How do I force Google Now to show updates from certain websites?
Google Now gives me updates for blogs that I visit regularly. But it's not very predictable in which websites it monitors. I see cards for SMBC and Channelate regularly, but not for xkcd. How can I teach it to notify me for xkcd too?

Visiting xkcd more frequently would do it.

I visit xkcd just as often as I visit the others. Sometimes I get updates even from blogs I don't visit as often. I'm wondering if there is a surefire way to see updates from xkcd.

Exchange mobile sync has been disabled using gmail
My Exchange mobile sync has been disabled twice already by the exchange server. The reason is that the corporate policy is to disable mobile sync when a connection is attempted from a different device id. I checked and the reason is that for some reason at certain times Android sends Device ID: 0 instead of the real one.
I am using Lollipop, latest exchange services (Nov 2014) and Gmail as a client.

Battery of Samsung Galaxy S5 drained in 5 hours on Android 5.0
I received the over the air android 5.0 update a week ago for my Samsung Galaxy S5. I installed the update and since that the my fully charged battery is depleted in 5 to 8 hours. Before the battery was depleted in 24 to 36 hours.
I have a spare battery with the same behaviour.
Below screenshots of the battery usage. Note the second battery:

High battery usage of Google Play Services could be caused by a number of things. A few suggestions I could make to help rectify your issue would be to:
1) Force stop the app; clear the cache and then allow it to restart.
2) Install 'Greenify' from the PlayStore and prevent the app creating wakelocks.
3) If you are rooted; try reflashing an Android L 5.0 Gapps package with recovery.

I am not rooted. I tried your suggestions. Unfortunately no success

The battery drain is caused by the Samsung stock app 'my magazine'.
If you click on the 'location icon',  located next to your wifi icon, you can see which apps often make location requests:
In this picture can be seen that the 'apps' geo news and unified daemon have a high battery usage. When I stop those apps, battery drain stops. Unfortunately after some time the geonews apps starts itself again.
The solution is to put unified daemon on turn off state:
And to disable the stock app 'my magazine', which is responsible for geo news, by long pressing the home screen and selecting 'home screen settings':  and after that uncheck 'my magazine':
Now my battery life is back to 24 hours (instead of 4 hours)

How to reinstall Playstore?
Do you have any Idea to reinstall Playstore?
Do I need to Flash it?
Do I need to reset factory?
Do I need to download apk?
Can you help me?
Please?
Device:Cloudfone 700d tv
I don't know how to reinstall this
I install apk version result: Google play has stopped
I install modded playstore: not enough memory

You can install it as an APK. Google search latest Google Play store. AndroidPolice.com is a safe, reputable site that will have it.

@RossC I very much doubt that. Might work to update, but not for a "fresh install" (as it requires permissions only granted to system apps). See: How can I install the Google Apps Package (Play Store, …) on my Android device?

@Izzy but to delete it in the first place you'd need root access so you can reinstall it surely? I can on my phone here

@RossC To delete it you'll definitely need root, as it's a system app. While in order to simply update it, it should be enough to "uninstall updates" and wait for it to update again.

Have you actually deleted it, or only disabled it?  Go into Settings > Apps, page over to 'All', and see whether Google Play Store (and Google Play services) aren't still there on the list; if they are, go in and re-enable them.

my phone doesn't load any picture i take with the camera
I thought there was some sort of problem with my camera but it works just fine except that it doesn't load the pictures i take with it. I take a picture and when i try to view it it turns out to be a black screen. And in the gallery it sometimes doesn't show at all. I also can't send them because it says "error loading media". And none of my photos in the gallery have a thumbnail. What can i do?
P.S. I have the 9gag app and it doesn't load any picture on it either; as in i can't view any post whatsoever. Also with instagram.

Strange, sounds like you might be missing a JPG decoder library or something.  What device and OS are you running?  Has this problem always occurred?

Do you have the camera app set to save to the SD card? If so, the problem may sit with a bad card or problems communicating with the card.

I have a lenovo running on  android i hope that's what you're asking me and Îmi fact, yes, i have my camera app  set to save on the SD card. Now that i think of it, this problem started the day after i changed that. So  basically every photo I took before changing the 'where to save' settings are still on my phone, but they still don't have a thumbnail. The photos I took after the settings don't show at all.

Should I install higher CWM on old device?
I am updating my Galaxy S3 Mini with Android 5. Here is my steps:

Copy the Lollipop firmware and Google apps package downloaded in the page above into phone (not sd card).
Because I meet the fail to verify whole-file signature error, I need to install ClockworkMod Recovery. I used Odin 3.10. The name of the recovery file is recovery-clockwork-touch-6.0.2.7-golden.tar.md5. I downloaded it from the #4 comment in this page. However when I checked back, it gave me 404 error :-/
Everything seems to be ok, the Lollipop was installed successfully. Nevertheless when I installed Google apps, I got the set_metadata_recursive: some changes failed error. The best answer suggested me to install a higher version of CWM, however when I go to the ROM Manager page of ClowkworkMod website, I see that the highest version of CWM for my device is 6.0.2.7, the version that I'm using.

So should I use the higher version of CWM, even though it's not build for my device?

After Matthew Read suggests me to recover, I repeat step 2. This time, I can't access the recovery mode. The phone screen keeps being black and after a while it restarts to normal mode.

Likely you can recover with Odin if you flash a bad recovery, but one that isn't tweaked for the device isn't likely to work.  Often the mount points will be messed up or it won't accept input from the hardware keys.

That 404 is a little disconcerting!  Try the CWM image from the official site (or touch version).  You could also try TWRP.

All three are corrupted. However the last link leads me to this recovery. After flashing it, the phone freezes in the welcome screen (Samsung Galaxy SIII mini...) when I access to the recovery mode.

OK, at this point I would recommend that you flash the original stock ROM with Odin, whatever version it shipped with.  It's hard to say exactly what is messed up here but it's probably safest to go to a known good state.

Does Android lock my external SD card in a special way so that it is read-only on a PC?
I just got a new 64GB micro SDXC card for my Samsung Galaxy S2.
I had the same one already before, but after 3 years it said goodbye and had to be replaced (I can still read all data, but writing is impossible).
I am now trying to copy all data from the old SD card to the new one and here's the problem:
Writing to the new card while it is in the phone through Android is no problem at all. As soon as I use an adapter and put it into my PC (tried both, Win 7 and Linux), it is read-only. And I tried two adapters with the lock switch in all possible positions. Still read-only.
I noticed that Android (4.1.2, rooted) formatted the SD card as exFat, but my old card was Fat32. I downloaded AParted and reformatted the card to Fat32, but no changes.
I tried unmounting it properly before shutting down the phone and inserting the card into my PC. Doesn't help, either.
I inserted the card into the phone, connected the phone to my PC. Then I could add data onto the SD card, but the folder ".android_secure" which seems to be necessary for apps to work that have been moved onto an SD card fails to copy because Android doesn't allow that. That was close, but in the end useless because .android_secure could not be copied - and I have a lot of apps on SD.
Any hint on how I could get the last method work (maybe there is a special startup mode for the phone which allows me to access the SD card from my PC without locking ".android_secure"?) or something else? I mean I really have to be able to use the SD card on my PC! I'd appreciate that a lot.

Why root cannot access “.android_secure” directory on external SD card?

Thanks for solving this after 5 years!

I wish I could do that earlier but my account on SE is less than 3 years old. You won't need the link anymore but it may help future visitors :) Your question is visited 800+ times.

Backup from recovery
After trying to install an OTA update, I'm stuck in recovery mode (system won't boot).
I'd like to know if I got any way to backup my datas (Contacts / SMSs / Enventually applications) from recovery like I would do with Titanium Backup and/or equivalent.
I'm using TWRP recovery, just in case.

I use CWM, and it has an option to restore only selected parts. Check if TWRP has that too. If it does, make a full backup, then re-flash a working ROM, then restore only data from the backup, and finally, clear cache and (if applicable) Dalvik cache. I can't guarantee it, but these steps worked for me when I softbricked my old S3.

@SixthOfFour : I got this option indeed, but does this also include SMS and contacts ?

I have contacts synced with Gmail, so I don't know about those. And my experience is three years old, so I don't remember about SMS, but I believe those are stored somewhere in /data.

OK, thanks, I'll try this anyway, don't got much choice!

@servabat If you backup everything (Nandroid), then it will have everything including, SMS, contacts, messages from other apps, all applications and even modifications done to the system partition (/system is backed up as well as /data)

@GiantTree : Yes but how can I use this kind of datas ? Is there a way to 'unpack' Nandroids ? (because I don't really wish to restore system as this one is bricked !)

@GiantTree If you restore only /data, the /system partition is left untouched by the restore operation. At least with CWM.

@SixthOfFour it's the same with TWRP. You can choose what to backup and what to restore.

@servabat all of the files (the .win ones) are images of the corresponding partitions. They usually have their file system format attached to the name (eg. .ext4.win for ext4 partitions). In Linux you can mount them as normal drives, in Windows it's somewhat more difficult, because there is no official support for those file systems.

@GiantTree : I'm using Linux, I'll try mount then. Thanks

Actually, I finally did a nandroid then used Titanium ! It has a function to extract from nandroids.

Cannot reset lock screen password
I have a Samsung Galaxy Grand and I forgot my lock screen password. I set a full 16-character password but now I forgot the password.
Somehow I unlocked the screenlock, but now I can't reset it to a simple one. I'm typing and typing the same password that got me in but no use. I don't want to reset the phone.

Assuming that there's not an issue with the password being correct, I'm wondering if there is a chance you set encryption on the device.
On my Samsung, that forces the password to be an actual password, as opposed to a PIN or swipe. In order to change the type of screen lock away from the high security password, you need to first decrypt the phone. It should then let you select the screen lock of your choice. Worth a shot to look!

the maximum character limit that the phone can remember for a password is 16 characters, but for some reason it can actually be longer. Try typing in only the first 16 characters, this should help.

If you have root access or twrp go to /data/system
Delete the following
gatekeeper.password.key

gatekeeper.pattern.key

locksettings.db

locksettings.db-shm

locksettings.db-wal

It will remove your lockscreen what ever it is
how ever if your device have fingerprint and you have set it
It will require your fingerprint to set a new lockscreen

galaxy s3 mini - notifcation sounds -how to turn off.
I have the default notification sounds set to silent but every few minutes a bell sounds. Does anyone know what is causing it?

There are several ways to chase this down.
I would start by checking the notifications bar to see if it will tell you what app is trying to get your attention.
If that doesn't lead you the culprit, take a look through the settings > sound area.  You may have inadvertently turned on screen lock sounds or dialing sounds or keyboard sounds.
If neither of those work, head over to settings > accessibility and look through the options for possibilities.

Why won't my android phone charge from my computers USB port? It actually seems to drain the battery
Why won't my Android phone charge from my computers USB port and why does it seem it actually drains my battery?

Many devices will use more power than that supplied by a low-power USB port.  Have you tried other ports or other computers?  Does the device battery icon indicate that it's charging?

To expand on Matthew's comments, from wikipedia (http://en.wikipedia.org/wiki/USB):

As with previous USB versions, USB 3.0 ports come in low-power and
  high-power variants, providing 150 mA and 900 mA respectively, while
  simultaneously transmitting data at SuperSpeed rates.[25]
  Additionally, there is a Battery Charging Specification (Version 1.2 –
  December 2010), which increases the power handling capability to 1.5 A
  but does not allow concurrent data transmission.[22] The Battery
  Charging Specification requires that the physical ports themselves be
  capable of handling 5 A of current[citation needed] but limits the
  maximum current drawn to 1.5 A.

In other words, it's worth it to try as many sources as you can find when looking for a good charging port.

What is Gapps (Google Apps)?
I have some questions regarding Gapps:

What is Gapps? Is it a custom ROM?
Do I have to install it on my Android 4.4 device?

GAPPS is not a custom ROM. It means "Google Applications" and usually includes Play Store, Gmail, Google Calender, and more. If you have some of these applications, then you already have some GAPPS.
Most users will only need to install GAPPS if they have installed a custom ROM that did not have GAPPS included.

Can u tell me how to install it?

You can install GAPPS by flashing a GAPPS zip file using either ClockworkMod (CWM) or Team Win’s Recovery Project (TWRP). Please see this page for details: http://wiki.cyanogenmod.org/w/Google_Apps#Installation

GAPPS is not required for normal smart phone functionality. Calls, SMS messages, internet and Bluetooth will work without.

"GApps" is an unofficial package distributed in several forms and places containing Google applications and frameworks, not a ROM. You don't have to install GAPPS, but many users may wish to do so in order to access Google Play store and some applications that depend on Google Play services. Smart phone functions such as calling, SMS messages, internet, Wi-Fi and Bluetooth work without GApps.
There's a replacement project MicroG in development and F-Droid is a comprehensive repository and "app store" for open source Android applications.

Galaxy Note Not Working with Apple Router
I have a new Galaxy Note 10.1 (2014) tablet that I absolutely love. I've been using it to take lecture notes and the thing is great.
The tablet's wifi works fine with every network...except the one I have at home. I have an Apple Airport Express that I use as a hub for my university's 100mbps Ethernet line; I've contacted Samsung support only to get the standard "talk to your ISP about DNS settings" canned response.
The weird thing is, the tablet says it's connected to my network, and my computer says that the tablet is connected as well...but no application that involves internet works...only on my home network.

I've run across a number of forum posts addressing this issue, but few dealing specifically with the Apple hardware and DNS settings. Any and all help would be greatly appreciated.

Apple almost always has compatibility issues...

going to best buy to grab a non-apple router later. serious issues with my Dell inspiron laptop too. competition is good for business, but these hardware firms make it a nightmare owning from more than one manufacturer..

What to do when play store tells "Authentication required you need to sign in with your google account" And then I sign up but still the same I can't install apps.

This is a common problem and is often solved with little work.
This should fix your problem:
1) Remove your Google Account (From you device settings)

2) Clear Google-Play-Store cache and data

3) Sign-in with your Google Account again

4) Try to download an app

Wifi symbol always show exclamation mark since Lollipop upgrade
Since getting the recent Lollipop upgrade, the wifi symbol always has an exclamation mark. Wifi seems to work fine, and I gather this symbol means something to do with inability to access Google services - but I use Google Inbox, and that works fine, too. I also understand that this symbol corresponds to the red-shaded wifi symbol of Kit-Kat, but I didn't have that persistently.
So what's going on? It's just slightly annoying.
Motorola Moto G, early 2014.

Might have something to do with this: http://android.stackexchange.com/q/100657/1465

Yeah, that answer offers a way to disable the "captive portal detection" - although I think it requires root to implement. It doesn't offer any insight into why I'm having the problem though.

Factory data reset not working after root attempt

How can I send SMS messages from my real phone number, not my Google Voice number?
This question is precisely the opposite of the existing question: "How can I send SMS messages from my Google Voice number without using the Voice app?"
Since installing the Google Voice app, text messages that I send from the ordinary Messaging app are coming from my Google Voice number. I don't know how or why - no setting I can find in the messages app mentions GV or my GV number.

I currently use my OnePlus One's built-in Messaging app for SMS. I installed Hangouts and Google Voice, but both are NOT configured for SMS. (I use Google Voice occasionally, but I still use my real cell number directly for most calls and texts to my friends.)
In the "Messaging" app settings, it says "SMS Enabled."
In the "Hangouts" app settings, it says "SMS Disabled."
In the "Google Voice" SMS view, it says, "You are now receiving SMS in Hangouts." This is obviously not true, but doesn't seem relevant to my problem either. (I'm guessing that the writers of that particular message couldn't conceive of any SMS app other than GV or Hangouts. :)
When I actually receive messages, I get them in the "Messaging" app as expected. When I reply to those messages, which were sent to my AT&T number, my replies come from my GV number, confusing my friends.

After further digging, I found the answer. In the settings app under "wireless and networks," there is a setting: "Enable all apps to send SMS messages through Google voice." Disabling this fixed it.

Even though you are using the default messaging app, open hangouts and go into the settings and check under Send SMS From.
It should say send from Carrier, if it says Google Voice, the default app could use that number.

Also, you may want to try to click on SMS Enabled and set it to disabled if it says enabled.

The hangouts app had "SMS Disabled," which meant that "Send SMS From" wasn't even an available option.

Android Low Memory: How to do factory reset of my phone when it won't open anything
My Android phone is constantly giving me a "Low Memory" error on the top of the screen. I would like to uninstall intensive apps or even do a factory reset (following online tutorials), but even if I open the navigator or anything else from the home-screen, the screen goes blank black and then the home-screen is restored after a while.
All the tutorials I find online to fix the error, to find which apps are eating up the memory, to delete caches and history, or to do a factory reset involve opening Settings, and doing some operations there. But my phone won't do anything.
I also tried connecting it to my PC but it fails to connect.
So my question is that what are my options? What can I do about it? Is there a way to di a factory reset right from the home-screen without opening anything?

Resetting a Device that's Off

Power down your device. Before you begin the reset procedure, you will need to completely power your device off. (If the device is frozen, you can pull the battery out to turn it off.)
Press and hold the recovery buttons. The buttons vary from device to device, so you may need to look up the instructions for your particular phone. You will need to press and hold the buttons for a few seconds. Some of the more common button combinations include:Volume Up + Home + PowerVolume Down + PowerHome + PowerIf none of the above work, do a web search for your phone’s model plus “recovery mode”.
Select Factory Reset. Once the recovery menu opens, you can navigate the menu with the volume buttons. You may need to open the Recovery menu to find the Factory Reset mode. Use the Power button, some models use the camera button, to select your menu options.You will be asked to confirm the factory reset.
Wait for the restore process to compete. After your phone resets, it will be set back to factory defaults and will be like it just came out of the box

Refer to this link . it has different ways for formating http://m.wikihow.com/Reset-Your-Android-Phone

WIFI & Data Connection Problem

Also while using data connection, I'm unable to see the symbol H, H+ or E. Why is it so?

You won't see your mobile data connection when on wifi because you are on wifi. You are only connected to one of them at a time, either mobile data, or wifi.

Uncheck 3G option on the 1st SIM, and click on 3G option on 2nd SIM.

Does Nexus 5 support EAP SIM authentication?
As the title says, I can't seem to get it working at all. I am running Android 5.0.1 on Nexus 5.

From the answer on SO by chihchun,

Since the AOSP did not have EAP-SIM support, there are different implementations on the market. [...]

(Emphasis mine)
Also, looking at the list of supported devices for EAP-SIM on this site, I didn't see any Google Nexus products, which might prove the statement on that answer.
Note: I would say that the list might be too localized and not too updated, so don't take it as a hard fact. Also, the answer was posted on Jan '14 (before Lollipop), so it might be outdated.
OTOH, it seems that Nexus 6 actually has this function, and Nexus 5 was supposed to also have it. However, Issue #81587 on AOSP Issue Tracker and Issue #509 on Lollipop developer preview might tell that Nexus 5 doesn't support EAP-SIM, even on 5.0.1 Lollipop.

is it possible to do manual login by extracting EAP-SIM info?

How to fix recovery mode
I cant go in recovery mode I try the combinations and it not work I always rebooted and bypass the recovery how to fix this

You have a very vague question, but generally speaking there are a few ways to boot into recovery mode:

Most devices have a key combination that should be held down when powering on.  You can find many of them on CyanogenMod's wiki.  Search for your device, and if it's supported you'll usually find the instructions on the Info or Installation page.  If it's not a CM-supported device, your device manual or web site may have the information, or you can look online.
From the Terminal Emulator app (available for download), you can enter the command reboot recovery.
From a shell, if you have adb installed, you can boot into recovery with the command:  adb reboot recovery typed from your computer.
Some ROMs (such as CyanogenMod, but others as well) allow you to select booting into the recovery from the "Shut Down/Reboot" menu in Android.  You may need to enable this feature.  In CyanogenMod 12, it can be enabled via the Developer options as Advanced reboot.
I believe some 3rd-party apps such as Rom Manager can also cause the device to boot into recovery mode.
If you are able to start in bootloader mode, some bootloaders will allow you to boot directly to recovery.  This can be done via the UI (on a Nexus device, use the volume up/down to select the correct boot mode, then press the power button to reboot to recovery).

Finally, you can also tell the device to start the recovery on the next boot by manipulating the cache partition, but that is more advanced and I think one of the above methods will probably work for you.

I wont boot in recovery whenever I try to boot it to recovery it always go in normal boot

You really need to say what you tried to make it go to recovery.  Any of the six methods mentioned above?

How to replace Nexus 5 battery?
As we all know, the battery in the Nexus 5 is sealed inside the phone chassis and cannot be replaced by the owner the way other phones' batteries can be. I am not particularly in favor of disassembling the phone by myself and manually replacing the battery. The point is, say I use this device for a few years: sooner or later it will need a new battery as the old one wears out. So how do I replace it ? Is there a safe, convenient way to get this done without taking any risks with the device ?

There is a free guide available on ifixit.com:
https://www.ifixit.com/Guide/Nexus+5+Battery+Replacement/26009
Of course, when disassembling the phone you always take various risks of damaging it, but I assume you are aware of that.

HDMI underscan fix
I am using this Android 4.2 NAND image with my Marsboard A20.
The HDMI output is working fine but there is some underscan (black borders around the screen).
The image has busybox and rooting pre-installed.
I've found here i need to edit uEnv.txt in order to fix it.
Btw, trying to mount the boot partition like this fails:
su
mkdir /boot
mount /dev/block/mmcblk0p1 /boot

What resolution does your Marsboard A20 hasve and what your screen? They seem to use different ones, thus the screen adds black borders where the screen region doesn't fit.

The Android image is set for 720p, while my LCD has a native resolution of 1080p. I've also tried the build set for 1080p and the screen was cropped instead (i could not see a part of it)

Then your "720p" has probably a different aspect ratio (16:10 instead of your LCD having 16:9) therefore you get those black borders.

Your question is a bit misleading because what you really need to know is how to modify a file inside the boot partition.
Your mount issue is probably there because the boot partition is running from a rootfs image contained in the kernel image and not directly from the mmc-device. You will have to unpack, modify and repack it, but probably it will get easier if you

Item that looks like the keyboard's Backspace key in the notification panel?
I would like to know what the icon that looks like a backspace keyboard key in the upper-left hand side of the notification panel means (what application does it correspond to?).
In the screenshot given below the icon is found in the very left-most position in the notification icons area.

Thanks.

If you can, please provide some kind of screenshot, so we know what you're talking about. Otherwise, I think the icon you mean is the indicator for 2 or more other notifications.

OK, I've added the screenshot.

This is the indicator for 2 or more other notifications. Their icons have been hidden because they would overlap other (system) icons.
The icon is not bound to an app (well, it's System UI but I don't treat it as an app) and is only removable by swiping away enough notifications, so that all the icons fit into your notification bar.

Would have been nice if you could swipe the notification icons left and right like you can do with the buttons at the top of the notification panel, clock app, etc...

Depends on the launcher you are using, some support this, other don't. Best way to do is to just copy the data to export to the phone to import (both need to be rooted, though)

If both phones are running the same launcher app, then you can backup the launcher on one device, and restore it on another.

I want to see why my apps take 5-6 seconds to switch to after my phone has been idle with its screen locked, and no WiFi or mobile data. Some program running in the background must have generated a ton of cache misses and filled up the entire L2 cache with its own data.
Is there a way to see, per-app, how many cache misses are being generated?

Ideally, if some messages would have had to be sent while the device was powered off, I would like the message sending to be triggered automatically on start-up (configured to the particular app or service used to send the message).
I'm thinking of using an app to send respective intents to each app.
Is it possible?

An app called Tasker, for rooted phones can schedule SMS messages. According to its site, it can also be configured for Facebook Messenger, though I have not tried it.

Well, not sure if I can root my Samsung Galaxy SIII Neo Android KitKat phone (wasn't even able to root the older SIII after it automatically updates its software). Besides, I've heard that if I do so then Google Wallet will stop working, is this true? I wonder whether there are any solutions which will not require rooting. Thanks.

@JohnSonderson Google Wallet works on rooted devices, it just displays a warning banner when you open it. I'm not sure that you actually need root in order to schedule an SMS in Tasker, either. It can use root for certain functions (like killing processes), but many work without it. Sending an SMS isn't something that should require root, since, for example, 3rd party messaging apps are capable of doing this. Sending messages in other apps (like Facebook) may require root, though.

Interesting about Google Wallet. As to sending messages, if the Facebook app is programmed to properly respond to the Android intent for sending messages, then this would work. Sending an intent doesn't require root. And an Android service can run in the background also without root. So I'm puzzled.

Actually this is false. There are support for third party apps and yes, given enough time you could create a Facebook API of your own where you could post messages via a HTTP POST relay.. But natively no, this app does not support the use of sending facebook messages.

Application setting not work
I have Micromax canvas gold a300 and its application setting not work when I try to open it show setting unfortunately stopped.
So I cant open application setting on my mobile phone.  Please help me

Are you rooted?  Have you tried a factory reset?

I'm afraid it may be a fault in Micromax's firmware. I suffered from the same issue on a Canvas Fire. Do a backup and a full wipe. If issue persists, contact your nearest service center or try installing a stable custom ROM.

SMS Forwarding in Android
I use a dual SIM Android phone.
Model: Micromax canvas 4 Android OS version :4.2
In this device, I have 2 SIM Cards, from two different carriers/operators. The issue is one of the SIM is flawed and looses connectivity often, sometimes when I am expected to receive SMS, at that very moment, I lose connectivity.
Hence, I want to forward this SMS to another SIM in same phone!
I already use Call forwarding on this device and it works perfectly fine, meaning if my SIM-1 looses connectivity, and someone calls on it, I still get the call on SIM-2, via call forwarding.
Is this possible with SMS?

Platform-tools not showing in Mac OS-X
I've downloaded the Android SDK, and am running the SDK Manager. I've downloaded all of the packages, including Android SDK Platform tools (v 21.1.2). However, I don't have a folder called platform-tools anywhere on my system.
Running OS-X 10.10.2

What folders do you see under the android-sdk directory (or wherever you installed it)?

I only see "add-ons", "platforms" and "tools"

platform-tools folder is created as soon as you install SDK components using the download manager. It uses to be at the same level of the tools folder (there's no option to change that during the installlation process it should have been there).
The only suggestion I have is to use the manager again, remove it to then download components again. Use to be in the top of the list that shows in the SDK Manager window.
Anyway, I don't suggest you to install the sdk "too deep" into the directory tree. I had issues with that.

The library folder is usually hidden on a mac. Do this. Open Finder. Click Go. Hold the option key and library folder will appear. After that navigate to the android folder>SDK> and you will find platform-tools there. If that didn't help, you can find some more in-depth instructions here.

Accidentally i have uninstalled my home launcher
there is no launcher in my phone.i also switched off and switched on . it showed only samsung nothing else.My device was already rooted and i thought by factory data reset it would work but now i can't  even open the recovery mode.i guess my phone is empty. please help me to fix it.

First thing first:

You have to Factory reset your phone and then reboot it, most probably it will get switched on. Then you create or login with Google ID (you can as I did it in my old Micromax A76).
Now tap on setting===>app===>Google Play===>launch. (If you have logged in, you can easily launch Google store by only this method if "Home Launcher" is uninstalled in any rooted Android device.
Now install any 3rd party launcher from Goggle like Go Launcher, Solo Launcher or any launcher.

Enjoy :) You have got your phone back from a Coma ;)
P.S.  emphasized text Please make sure you are not doing Factory reset again without putting the apk of your current launcher in root folder.
Feel free to ask anything regarding this post.

Try method of Shri Bhagwan described or you can always use ADB to push an app into your phone.
When phone boots up, complete the welcome procedure(Name, Google account adding etc.) then open status bar and go to settings and turn on USB Debugging.
Then open terminal(Linux) or cmd(windows) and write adb install (appname).apk
Make sure you have adb binaries to execute command and required drivers to recognize your phone.
Hope it helps. :)

Location history shows wrong place
I am trying to find out how on Feb 18th and 19th of 2014, I was in Louisville Ky, but my location history is showing that I was in Somerset Ky.
Why did this happen?

Your location was probably pulled from wifi only, as opposed to GPS (this saves battery; you can check this setting in settings > Location > mode).  The wifi setting pulls its location information from the ISP, rather than your actual physical location.  Mine frequently tags me a dozens of miles away.

Replaced /system/bin/toolbox. How to I revert that?
I renamed the original /system/bin/toolbox" to "toolbox_alt".
I replaced the file /system/bin/toolbox with a file that was supposed to work, but doesn't work at all.
My filemanagers and the most terminal comands have stopped working and I apparently lost root access.
I have a Samsung Galaxy Note 3 (N9005) (International) running the newest Cyanogenmod nightly.
Can anyone help me deleting the current toolbox and renaming the "toolbox_alt" back to "toolbox" ?
Thanks ahead

Have you tried re-rooting?  You might be looking at a factory reset.

I fixed it myself.

I went to the recovery menu (CWM)
Mounted /system
Plugged it into my Laptop
Opened ADB on my Laptop Comand: adb shell
went to /system/bin and replaced the file

Hopefully this helps other who do the same mistake!

Connect to Sony Xperia M Dual with adb/fastboot
I want to ask how to install custom rom on Xperia M Dual
I had tried adb and fastboot command in cmd but it shows waiting for device..
Help me please I'm too frustrated

Sounds like you didn't install the proper usb drivers. Easiest way I can recommend: Boot a linux live system, install fastboot and adb and execute the commands as root.

But I'm running on win7 64 bit

That's why you should try a live system which does not require installation. Ohterwise, try to properly install the usb drivers for windows 7, without them your device will not be detected.

How do I backup my contacts that are on an excel file into my nexus 5 phone?
I have all my contacts saved in an excel file with name and phone number headers :)
Does anyone know how can I restore them into my new nexus 5 phone ?

Should I assume, from your question, that you have no desire to sync Google contacts?

If you are signed in to a google account on your phone, you can use Google Contacts and import a CSV of your contacts.

I did the same steps but Google didn't recognize the format or put the names and phone numbers in the comments section, they weren't correctly saved :)

You're going to have to provide more details on the file format you have if it's not saved as a standard CSV.

Check its format
If .CSV
Put that .CSV file into your SD-Card or internal then.
1. Go to contact > Menu

Import from storage
Select that .CSVfile
Then it automatically scan and add them to your contact list.

Assuming you have excel application
Name    Given Name  Additional Name Family Name Yomi Name   Given Name Yomi Additional Name Yomi    Family Name Yomi    Name Prefix Name Suffix Initials    Nickname    Short Name  Maiden Name Birthday    Gender  Location    Billing Information Directory Server    Mileage Occupation  Hobby   Sensitivity Priority    Subject Notes   Group Membership    E-mail 1 - Type E-mail 1 - Value    E-mail 2 - Type E-mail 2 - Value    Phone 1 - Type  Phone 1 - Value Phone 2 - Type  Phone 2 - Value Phone 3 - Type  Phone 3 - Value Website 1 - Type    Website 1 - Value

1.Copy the above text and paste it in excel sheet. Each fields will be pasted as seperate column.
2.Now update the required field (Name , Group-membership(ex:Mycontact), Phone 1 - Type(ex:Mobile)   Phone 1 - Value(ex: 9999999999) are required). You can leave the rest as blanks.
3.Save the file as filename.csv
4.Copy the file to phone.
5.Install this app
6.Export as vcf file
7.Open contact and import vcf

Looks like the app is not available on the Play Store anymore (you may still be able to see the entry on the Play Store if you have installed it before). Any other alternatives?

Nexus 5, I'm getting remote: flash write failure while trying to fix a bootloop
Before I say anything I just want to say I didn't install any custom ROMs nor rooted my phone.
I've downloaded the factory images from here https://developers.google.com/android/nexus/images#hammerhead
I put my phone into bootloader and I start the flash-all.bat script from the folder I've downloaded above. It runs this script:
PATH=%PATH%;"%SYSTEMROOT%\System32"

exit

I get the following output:

I've noticed the bolded lines so I unlocked the phone using a command fastboot oem unlock. It unlocks it, however if I reset the phone, it's locked again. People on the Internet say that if this happens then the phone is dead. I hope it's not the case.
I've tried running the script again when the phone is unlocked:

As you can see I get the FAILURE (remote: flash write failure).
I've tried removing the commands that reset the phone so the phone stays locked and I get this output after running the modified script:
target reported max download size of 1073741824 bytes

Press any key to exit...

Again, the FAILURE (remote: flash write failure) occurs but I don't understand why it can't find "system.img" because it is in the folder where the script is.
I've also tried the tutorial from this Youtube video https://www.youtube.com/watch?v=pJnoiMTw5cY
When I try the first command which is "fastboot flash system system.img" I get the same error.
So, is my phone dead or can I still fix it?
EDIT: I've RMA-ed[1] the phone and they've sent me a replacement. I hope this thread will help future people.
[1] https://en.wikipedia.org/wiki/Return_merchandise_authorization

In this thread they told me my emmc is fried because I can't lock / unlock my phone so I RMA-ed it.

The flash-all.sh script does not take into consideration that your bootloader is locked after each restart.
I opened the shell script and executed each command one by one, re-unlocking with the following after each command:
fastboot oem unlock

I flashed each image with no errors, but it did not seem to write to memory regardless.

I get FAILED (remote: Already Unlocked) even tough it is freshly rebooted.

Be careful. Unlocking bootloader will delete all personal data.

The interesting point is: Although you don't get these "only allowed in unlocked state" warnings anymore, is your bootloader really unlocked? What output do you get when you run the following command in unlocked mode?:
fastboot oem device-info
And: Can you still boot into recovery?

C:\Users\Neven\Desktop\hammerhead-5.1>
...
(bootloader)    Device tampered: true
(bootloader)    Device unlocked: true
(bootloader)    off-mode-charge: true
OKAY [ -0.000s]
finished. total time: -0.000s
I can boot into recovery mode. The little android with an exclamation mark inside a red triangle shows up. I tried wiping the cache and factory resets but as far as I've understood it failed. I can't photograph the screen at the moment. What's also interesting is that I don't have "wipe Davik-cache" command but I've heard I should have that.

Maybe try booting from fastboot into a custom recovery with 'fastboot boot recovery your-recovery.img' From there, You could try to flash the system partition from a ZIP file, but the behavior you describe is very unlikely and it seems like you cannot write anything to your mmc-device (the flash chip), since even wiping cache seems to fail. Would be interesting though to see if you can mount partitions r/w in custom recovery and modify their content from there. And since you said you didnt do anything with custom roms, how did you get the bootloop problem in the first place?

@kulesdzl I tried the first command but got this error
C:\Users\Neven\Desktop\hammerhead-5.1>fastboot boot recovery recovery.img
cannot load 'recovery': No such file or directory

Of course you have to load a proper recovery.img before attempting this. I recommend using a recovery from the twrp project, you can get images here: http://techerrata.com/browse/twrp2/hammerhead

I've downloaded images from https://developers.google.com/android/nexus/images#hammerhead I have a recovery.img so I don't know why it says it can't find it. I don't know what caused the boot loop. I didn't install custom ROMs nor rooted my phone. The last thing I remember what happened is that my phone started lagging and I was getting app.google.etc. stopped working. Don't remember the exact error. So I googled and people said to wipe the cache of google's applications. So I did and the phone started working again. The phone restarted itself somehow in my pocket and entered bootloop later.

Well, this is the stock recovery which will not allow you to do quite much, and you will not be able to connect via adb to it. Therefore, try booting a custom recovery to be able to get an idea what is going on from the command shell.

Wipe cache from recovery, make sure you have latest adb and fastboot files.
In the recovery menu, execute these commands.
adb shell
recovery --wipe_data
recovery --wipe_data

The supplied commands :
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot

Use Nexus Root Toolkit to do the job done : http://www.wugfresh.com/nrt/

Here is how you can get into adb from an unwriteable emmc:

Download twrp, extract it so you see recovery.img.
Unlock using fastboot oem unlock.  do not reboot.
Boot into the custom recovery (not flash) using fastboot boot recovery.img.

You will now be rebooted in twrp, from where you can access adb and adb shell.

I have the same issue and haven't been able to find the recovery.img file inside any of the twrp images. I feel like I am doing something wrong or am looking at the wrong img files maybe. Is there a link to where I can get the correct TWRP? Thanks!!

Mount EncFS on Android KitKat 4.4
On older (rooted) Android versions, Cryptonite was a great solution to mount EncFS encrypted folders, but on my new Android KitKat phone with an emulated storage, that fails.
I can successfully mount the encrypted folder in /storage/emulated/legacy onto another folder in /storage/emulated/legacy, but then the decrypted files are not visible to other apps. How do I mount an EncFS folder the right way?

How are you mounting it?

@Mathew What do you mean exactly? The encrypted folder is in /storage/emulated/legacy/encfs.crypt and I tried to mount it in /storage/emulated/legacy/encfs. Cryptonite offers a gui to mount encfs folders. (The folders also exist in /storage/emulated/0, but that doesn't work either.)

Can someone with the needed rep add tags 'cryptonite' and 'encfs' to this question?

The problem turns out to be a new security feature in KitKat. Apps by default have their own mount namespace, which means that mounts created by one app are not visible to a different app.
Secondly, Android phones without a real SD card use emulation for the fake SD card, and that gave me some problems.
SuperSU from Chainfire has an option to access the root mount namespace that allows a program to mount filesystems and have them visible to all other programs. Unfortunately, Cryptonite doesn't know bout this option. One solution is to interpose a script before the encfs binary that Cryptonite uses.
You will need a root shell to run these commands, probably from a computer using adb to connect to your phone over usb. (But using a terminal app could also work.)
Steps:
Move to the cryptonite data directory:
cd /data/data/csh.cryptonite

Note the Cryptonite user id:
ll -d -n .

This will give output similar to drwxr-x--x   11 10133    10133         4096 Feb 14 23:51 . The 10133 is the user id of Cryptonite (the second copy is the Cryptonite group id, but that should be the same).
Create a folder to store the original encfs binary in, and give it the right owership
mkdir original
chown 10133:10133 original

(replace the 10133 with the user id cryptonite has on your phone)
Move the original encfs away
mv encfs original/

Create a script named encfs to interpose for the real encfs. I prefer to use the nano command for this, but you could also create the file in a different way and move it using the command cp /path/to/encfs/replacement/file/here /data/data/csh.cryptonite/encfs
nano encfs

Put the following content into the replacement encfs script
#!/system/bin/sh

cmd=/data/data/csh.cryptonite/original/encfs

for param in "$@"
do
    replaced=`echo "$param" | sed 's:^/storage/emulated/:/data/media/:'`
    cmd="$cmd $replaced"
done

su -mm -c $cmd

Save the file with ctrl-x (volume down + x on some terminal emulator apps), answer y to save.
Make the replacement script executable
chmod +x encfs

Set the right owner
chown 10133:10133 encfs

(Again replace the 10133 with the user id Cryptoite has on your phone)
That should be it. Mounting an encfs folder from /storage/emulated/0/ onto a different folder in /storage/emulated/0 should work now.
What it does
The replacement script does two things: replace paths to folders from /storage/emulated/something to the actual place where the emulated SD card data is stored, and call the real encfs in the root mount namespace so that the mounted encfs folder is visible to al apps.
Changing the folder paths is necessary because for some reason mounting on the emulated SD card doesn't work (at least for me). The emulated SD card in fact stores its data in /data/media/0. By mounting on the actual storage location the SDcard emulation layer doesn't need to know that there is a different filesystem involved.
Directly mounting a file on /data/media/0 from Cryptonite doesn't work because the Cryptonite app doesn't have access to tha folder, so the replacement script changes the paths of the mountpoint and encrypted folder to point to the underlying SD card storage.

I have no problems to mount containers with EDS App correct work with all Android version

What's your relationship with this app? If you're the author of the app you must say so in your answer, otherwise it will be deleted.

fastboot oem unlock: hangs with `...'
First of all, I am a newbie to Android. I am using Ubuntu Gnome 14.10 to run all the commads.
I am trying to unlock the bootloader of my Lenovo A536 (stock Android 4.4.2 aka KitKat). Here is what I am trying to do:
$ adb devices              # lists the devices, apparently working
 List of devices attached
 0123456789ABCDEF   device
$ adb reboot bootloader    # no terminal output; phone enters fastboot
                              (there is written '=> FASTBOOT mode...' in the
                              bottom-left corner
$ fastboot oem unlock      # and here it stops without exiting; I have to force quit
 ...                          the fastboot by holding the phone power button for over
                              10s and then the command in terminal ends'
Before doing this I checked the USB debugging in the Developer’s menu.
Update #1
lsusb output (part of it) while the phone is connected to pc and booted in fastboot:
$ lsusb
Bus 002 Device 064: ID 0bb4:0c01 HTC (High Tech Computer Corp.) Dream / ADP1 / G1 / Magic / Tattoo
Update #2
I found out that after installing a USB VCOM Driver on a Windows machine I was able to flash TWRP 2.7.1. I think Linux somehow does not recognise my phone.
Here is the link with tutorial to flash TWRP 2.7.1 using Windows. Note that before running SP Flash Tool, you must connect phone without battery to the computer, and after selecting the scatter file, you must insert battery into phone, otherwise SP Flash Tool would not flash anything.

Does lsusb show the device connected while it's in fastboot mode?  Do you have the appropriate entries in /etc/udev/rules.d/51-android.rules?  You might also have better luck running the command as the superuser.

@MatthewRead – I have just appended the lsusb output to the question. And I have not such file as /etc/udev/rules.d/51-android.rules – should I create one? what should I contain? And running the command as superuser has same results.

Step 3: http://developer.android.com/tools/device.html#setting-up

I just created the file with sudo sh -exec "echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="17ef", MODE="0666", GROUP="plugdev"' > /etc/udev/rules.d/51-android.rules" && sudo chmod a+r /etc/udev/rules.d/51-android.rules (using 17ef for the phone is a Lenovo), but still it hangs with the elipsis …

I tried even sudo sh -exec "echo 'SUBSYSTEM=="usb|usb_device", ATTR{idVendor}=="17ef", ATTRS{idVendor}=="17ef", MODE="0666", GROUP="plugdev, OWNER="ts", SYMLINK+="android_adb"\nSUBSYSTEM=="usb|usb_device", ATTR{idVendor}=="17ef", ATTRS{idVendor}=="17ef", MODE="0666", GROUP="plugdev, OWNER="ts", SYMLINK+="android_fastboot"' > /etc/udev/rules.d/51-android.rules" && sudo chmod a+r /etc/udev/rules.d/51-android.rules && udevadm control --reload-rules, and then adb reboot bootloader && fastboot oem unlock, but the result is still the same.

Alright, I think we can probably rule out your OS/tools being the issue (although it wouldn't hurt to try Windows if you are able).  I can't find very much information on this device.  Are you sure the bootloader is locked / have you tried flashing a recovery image?

I tried to flash TWRP prior to unlocking the bootloader, but it would not let me do it (I just cannot remember the error). And yes, it is difficult to find any valuable information on this device about unlocking, rooting, and flashing :). I will try the m$ window$, but wanted to do it  without it—well, it should be easier to do it on Linux machine for android is basically a heavily modified Linux, but I do not know how.

I have the same problem. The symptoms show a Linux problem, what is really sad.

I don't have enough reputation on 'android' to answer the question, but see this answer I posted to XDA Forums: https://forum.xda-developers.com/t/all-fastboot-commands-hang-except-fastboot-devices-bad-hardware.4184331/
TLDR this works:  /usr/lib/android-sdk/platform-tools/fastboot oem get_unlock_data

Touch lags in all apps, except keyboard
I've noticed a delay of about a quarter of a second between tapping the screen and the app responding. Thud happens in all apps - it's most obvious in the game "aa", a fast, reflex-based game which is essentially unplayable with so much lag. The lag is also clearly visible in CyanogenMod's calculator app, where it clearly can't be attributed to complex or expensive rendering.
The only place I don't see the lag is the keyboard - keypresses register instantly.
Rebooting the phone in safe mode does not solve the problem.

I figured out the cause as I was writing the question - the "triple tap to zoom" accessibility feature was enabled. This means that the phone can't register any taps until waiting to make sure there isn't another tap.
Disabling this feature removed the delay.

USB driver for Verizon's Samsung Galaxy S4 SCH-I545VRUFNK1
I have a verizon S4 with which I plan to do some android development. Samsung's download website doesn't have a usb driver for the above mentioned model number.
I installed SCH-I545ZKAVZW's usb driver because it is for 16gb black mist devices, but android studio doesn't pickup my device.

You could try the universal ADB driver: http://adbdriver.com/documentations/how-to-use-android-adb-driver-installer-for-windows-xp-vista-7-8.html

C:\Program Files (x86)\Android\android-sdk\extras\google\usb_driver\android_winusb.inf

Otherwise, you can download the driver here and edit android_winusb.inf from wherever you extract that archive to.
Edit the [Google.NTx86] and [Google.NTamd64] sections to add these lines under both:
;Samsung Galaxy S4
%SingleAdbInterface%        = USB_Install, USB\VID_04E8&PID_6860
%CompositeAdbInterface%     = USB_Install, USB\VID_04E8&PID_6860&MI_00

Now you want to install the driver by right-clicking adb_usb.inf and choosing Install (make sure your device is connected).  It will probably give you an error about Driver Signature Verification.  Depending on your version of Windows there are different ways to temporarily disable that; here is a good guide for Windows 8.  Once it's disabled, install the .inf file and you should be good to go.

I followed every step, the galaxy s4 still won't show in android studio.

@u530891 That is very odd.  Are you able to transfer files and such to the device from your PC?

You may be right. The connection is very intermittent. I tried 3 different cables, same problem. Wondering if the micro-usb  port in my phone is gone.

SD card damaged
My phone model is Micromax A77 operating system is 4.2.2 jelly bean.SD card company Sony. My phone shows that SD card is damage format it.I format it but not shows.I restart it I again shows to format it again not show SD card

Have you tried another card to be certain the slot is good and the phone can read it? Have you tried to fix the partition table on the card? (You'd have to do it with a PC/Mac/Linux program).

Try checking if the SD card is recognisable with an other phone or computer, in case it is still not working this could mean that your SD card is spoiled. If it works in an other phone or computer, it could be a problem with your phone.

How can I restore a deleted file that I should not have deleted?
I used titanium backup to delete something I shouldn't have deleted and than I factory reseted my phone and now I can't log in with my Google accounts ,can anybody please tell me what I have got to install for this ?

If you deleted something from /system, the only way to fix it is to either copy the file back on to the device manually, if you can find the file. Or flash a new ROM to the device using something like ODIN (or via recovery)

There's a free app on the play store called Undeleter that may help once you can root your device again. It sounds like you erased your Google play services, Google framework, and possibly your Google+ /data when you wiped it. Which is normal. Titanium backup's /data is stored on your sd card, or even internally sometimes in a different directory that is most often protected by root even when you factory reset it.
Boot into recovery using the button press sequence, factory wipe it, and the Dalvik cache, adb push a stockROM.zip file from the manufacturer or just Google search it.
Reboot back to recovery and flash the Gapps file, which also is a .zip file, for your specific Android device, and reboot one more time.
Wait five or ten minutes while it loads the first time. Mine have taken 30 minutes before just after flashing a new ROM, so just have patience. Then you can link it to Wi-Fi and reload your Google account info.

Message app uninstalled after using viber?
I could only text people using viber, which is not usefull for out of internet zones. I uninstalled viber thinking it was a default thing. My samsung Galaxy Note 3 has uninstalled the texting application. I have since deleted viber and cannot text anyone, how do i fix it?

"just solved the issue. apparently when an app is 'disabled' it ends up at the bottom of the HUGE list under application manager -> all apps
when you 'enable' the app, it re-joins it's place in the ranks alphabetically"
found this on another site,
for me it was in the tab "disabled apps"

connection between spell correction, language selection, predictive text, and keyboard
Can someone please explain to me the android conceptual model between

language selection
spell correction
predictive text
keyboard

I.e., is it the responsibility of the keyboard app to support multiple language, provide dictionaries, and analyze the sentences you type to try to predict the next word?  Or is the keyboard just responsible for noticing where your fingers touch and providing characters to another program which does the checking and prediction?

In most android keyboards, the keyboard app has its own dictionary and language packs. It records the language in the keyboard's data base. Spelling correction and predictive text depends on the language data, the script of the language that was selected and your most used words and sentences. It remembers your sentences or any new words that you type and try to help you complete your sentence by using the previous record of your conversation or anything.

"not executable: magic 7F45" when running redsocks on Android emulator
I'm trying to get ProxyDroid or redsocks to run on the Genymotion Android emulator (x86). ADB shell into the device, run redsocks and I get not executable: magic 7F45.
I know it means that the version doesn't comply with the CPU. However, on Genymotion, I'm able to run a bunch of ARM packages with no problem (having installed the Genymotion ARM translation files).
I have compiled redsocks sources on my Ubuntu box (binary works fine on my Ubuntu x86), but when I copied the binary to the emulator, it still gives the same error message when I try to run it (not executable: magic 7F45). So, it looks like neither the ARM nor the x86 versions are working on the emulator.
I also have taken the redsocks binary that I compiled on my Ubuntu x86 box and pushed it to x86 AVD (standard SDK) - it worked perfectly. So it appears that the not executable: magic 7F45 error is not related to the cross-CPU compilation?
Is there a way to get redsocks run on Genymotion?

What file(1) utility says about your compiled binary?
Because compiling on x86-based PC does not promises your binary always will have x86 target platform - GCC can produce virtually any targets.

You can't freely copy binaries from your Ubuntu box to emulator one - even if all are x86-based, they use different basic OS libraries.
To compile binary for Android-x86 target you must use special cross-compiling tools\environment. See Android sources toolchain to take a look on how they configure gcc+ld switches to create android-x86 binaries on Ubuntu box.

Can't delete app because it isn't there
I have an LG L70 and was downloading an app that was about 470 megabytes and then i got a notification saying that there wasn't enough space on the phone to download it so i clicked it and it looked like it wasn't installed. I checked the memory on the phone and the app wasn't there. Did the phone download the some of the app but not finish and still keep the app? Because it still took all the space but it isn't there. I want to delete it but don't know how.

Most likely the "partly download" still sticks around somewhere. Usually in /data/local, where you might wish to explore with e.g. a file manager.

Go to: Settings -> Application manager -> All and search for Download Manager. Click on it and then click on Clear Data.

List of intents and registered apps for those intents?
Is it possible to view a list of intents and which application is set to launch when such intent is issued by an application? It would be nice if the OS provided such a feature where you could also change this as desired or even clear this setting for any intent so that the user would have to choose from a list of apps to open the intent with when the intent is issued. It would also be nice if on such screen one could make exceptions for apps which would open a different application than the default one for a given intent (and this could thus be set on an app-by-app basis).

There are a couple of apps doing exactly that, see my list "Manage Default Apps".

Thanks for the list, but couldn't find what I was looking for (an app which actually lists the intents by their name with all the dots separating the various parts of the intent name). Anyways, for an app which opens an intent you can clear it from being the default app. I wish I could get the Intent Analyser and Intent Intercept apps to work but they're not working for me (interception fails).

If you want to explore an app's intents, all I can think of are apps like Activity Launcher (Apex Launcher has that functionality built-in as well). But those won't show you where they are used.

Have you looked at the output of adb shell dumpsys package?

No I haven't. As a matter of fact I've just installed Android Studio, but when I type adb at the DOS prompt I get command not found.

How do I move screens in the app drawer?
I have a Samsung Galaxy S5.  I have a bunch of apps installed.  From the home screen, I can tap on the Apps icon.  This takes me to the App Drawer.  In the App Drawer, I have 2 screens full of icons of apps.  I have a 3rd screen full of folders with icons of apps in them.  I would like to move the 3rd screen so that it becomes the first screen.  How do I do this?
If I were on the Home Screen, I can long press to allow editing the screens.  Here I can long press on a screen and move it to the left or right of other screens and reposition them.
This doesn't work in the App Drawer.  I can't seem to do this in the App Drawer.  I tap on the menu and tap on Edit.  I am not able to reposition the screens.

I'm pretty sure you can't move whole screens, just individual apps.

You can't, and I don't think you can on any custom launcher either I'm afraid. You could try Nova / Apex / Go launcher or similar (all are free) and see if they meet your needs.

Gallery application replacement for adding text based Photo Notes
The Samsung Galaxy SIII Neo stock Gallery application has (and other models do too) an option to set a Photo Note when you're viewing a picture. When you select it the picture rotates via some OpenGL animation, and you can scribble on its back. But the space is limited, whereas attaching a note using the virtual keyboard would make it possible to enter a virtually infinite string of characters inside the EXIF data. Beasies the fact that I'm not even sure how to view the scribbled notes (or EXIF data!) once you transfer the picture to the PC (perhaps someone can explain), this feature would be really useful.
Anyone know how I can make use of the feature I'm after?

There are a number of photo apps that will let you edit exif data on the android.  This one specifically does the data: https://play.google.com/store/apps/details?id=com.teapps.exiftageditor, some do other pieces of editing, some sort your files for you, etc, etc.  Take a look around for one that works well with your particular image work flow.
Wikipedia has a nice roundup for PC/desktop meta data editors here: http://en.wikipedia.org/wiki/Comparison_of_metadata_editors. Your choice will of course depend on your PC, budget, and needs.

How to retrieve files from Samsung Galaxy S4 stuck at samsung logo after dropping it?
I dropped my Galaxy S4 GT-19500 and after i picked it up it was still open but when i tried to phone a friend it just turned off and kept turning on and off, it reaches the Samsung logo then immediately turn off and when i plug it to the pc or the charger it shows the big battery bar but empty with the circle and also flashing on and off like the Samsung logo, the problem is when i try to turn it off it doesn't turn off and when i take the battery and put it again it just go on alone, so i can't enter safe mode or recovery mode and can't connect it to the PC and Dr. Fone, i think it doesn't charge when i leave it too.
So what i need is to get the photos from my phone, i don't care what to do I will do it! Please help me I really need those photos i don't care about the phone XD.
If it's not possible to get the photos with the known ways, Is it possible to take the default SD card of the phone and take the photos from it ?
Thanks

First, odds are good you can salvage your photos.
Provided you did not encrypt your sd card, pull the sd card and take a look at it with a desktop/laptop (you won't be able to pull anything useable off of it this way if you did indeed encrypt it).  The images will be on there if you set up your camera app to save them there.  Otherwise...
Hardware repair on the phone will be required to get the connectors all back and sorted out (it sounds like you managed to short or unplug some bits, and perhaps damaged connectors on the motherboard). If you are feeling mechanical we can walk through looking at it; if not, we can suggest other repair options.

I really don't feel mechanical xD, I'd like your other repair options because I'm very bad when it comes to the hardware things. Thanks

@GasserTarek it takes a brave soul to admit that ;-)  I'm not sure that we can actively recommend vendors here, so I'll go with a generic "start with where you bought it" and ask them for prices on the repair (yes, it will be pricey). You can also google for mail-in repair services, but do your homework on them - you don't want a place that will lose the photos by careless repair.

Galaxy Avant - "Lock automatically" turns Keyguard back on
I have a new Samsung Galaxy Avant and I want to setup tasker like my old phone, specifically to turn off the Keyguard when I'm home.
It works, until the "Settings > Lock screen > Lock automatically" kicks in and turns it back on. Ive tried making another tasker action that turns Keyguard off again say, 10 seconds after the screen turns off, but that doesn't work and the Keyguard stays on. I'm not against rooting the phone, but I don't think it's needed since the Keyguard does stay off in the short time period between the display turning off and lock automatically triggering.
I'm guessing Lock automatically is a Samsung thing. Is there a way around this, or to turn off Lock automatically?

I was wrong when I said Lock Automatically was turning the Keyguard back on. If you reopen the phone before that timer ends, the Keyguard has never been set to begin with and has nothing to do with the Tasker profile.
Anyway, to get around this I did need to root. I also needed to install secure settings. With that out of the way, the setting that needs to be set on/off is Plugin > Secure Settings > Edit Configuration > Root Actions > Pattern Lock (this might be different if you are using a different type of Keyguard).
There is one last thing to note. When the Pattern Lock turns off, it reverts to whatever type of lock was being used before it turned on, so if you want it set to None, you need to have it set to that beforehand.

Auto-mount microSD when plugging phone to computer with USB
In short: How to automatically mount the microSD-card as a storage drive when I plug the phone to computer?

When I want to connect my Android 2.3.6 phone (with USB cable) to computer (Windows 7 / PC), I have to

unlock the phone (slide finger on screen)
slide to make the top notification panel appear
click on USB connected / select to copy files to/from your computer in the notification panel

click on "Connect USB storage"

Accept the warning message

wait...

So many steps!
Instead of all these steps, I would like auto-mount the microSD-card as a storage drive when I plug the phone to computer. How to do that?

The first question is: are you willing to forgo locking it? I don't think there is an automatable way around this (for good reason). Second: PC or Mac or Linux?

@LivedWithOtters No I don't want to forgot about locking screen... 2nd question: PC Windows 7.

Based on your answer in the comments (apologies for not catching the OS in your initial post), you're going to still have to unlock by hand.  Past that step, I would recommend trying Macrodroid, Tasker, or other automation apps to see if they can help out. I've not used them to automate connections like this, but they are great in other situations, so I have great hope for a solution here for you.

Shouldn't there be an option in Settings like "Auto-mount on USB connect?" I can't find it, but it seems that it exists on some phone running Android : http://android.stackexchange.com/questions/15380/every-time-i-plug-in-my-phone-via-usb-it-automatically-mounts-the-sd-card-xperi?rq=1

@Basj What happens when you change that setting to msc? Can you skip login on the phone and see it directly with the computer?

I can't even find this option @LivedWithOtters... I don't have "Connectivity" menu...

@Basj Do you have this Settings > Applications > Development on your version of phone/OS?

Yes @LivedWithOtters, but I only have "USB debugging" (on), "Stay awake" (off), "Allow mock locations" (off) and sadly, no other option here.

Why does my unplugged Nexus 5 keep shutting down after any app usage?
I bought a Nexus 5 a year ago and it has been running fine. After the Lollipop update, my phone has started crashing. Even though the phone has enough battery, if I run any app for like 5 minutes (it happens for any app, no particular app I could isolate), the phone just crashes to a black screen. When I start it again, the battery has suddenly gone to zero from its initial healthy number (e.g. 40%) and the phone shuts down again (sometimes even at the loading stage after the "Google" display on starting). But if I charge my phone even for a second after it crashes and then restart it, then the battery shows up as 40% (or whatever it was pre-crash) again. But then the phone crashes again after I use it. If I don't run any apps, then the phone does not crash.
Does anyone know the solution to this problem? Please help because now I can't use my phone even for 5 minutes without giving it a charger jumpstart!
Note: The phone never crashes when it is plugged to a charger no matter how many apps I use. It only crashes if it's unplugged.

You might want to try wiping the battery stats from Recovery while fully charged, and then do a full drain/charge cycle while it's powered on.

Quickly switch back to in-progress call or navigation?
One of my favorite iOS features is that, when you have a call or turn-by-turn navigation in progress and switch apps, you can easily return just by tapping the status bar.
In android, I've noticed a number of apps that can show floating widgets over other apps - Facebook messenger's floating "chat heads" and CyanogenMod's floating calculator widget are good examples.
Is there any way to make similar floating icons appear when on a call or when navigating in the background, that when tapped will quickly return to the relevant app?

In Android 4.4 on Samsung Note 4, while you are using an app, phone calls will pop up as a small moveable window on top of that current running android app. You can maximise/minimize that moveable window. This might be a better solution to multitasking while having a phone call on the same device. I am not sure cyanogenmod have the similar features, though.
However, stock Android 4.4, have a pull down notifications window. Applications such as Google Maps Directions and Waze, will put a notification icon in the notifications status bar while you are navigating, so pulling down the notifications window will allow you easy access to switch back to the navigation application. As the screenshots shows the notification window have resume navigation bar at constant place in the middle of the screen, on top of other notifications.

Yes, I know I can get back to a phone call or navigation from the notifications window. That's sill a little inconvenient though. (Especially while driving, I don't want to have to look away from the road to browse through the busy, complicated notifications list looking for Google Maps.) I was hoping for something even easier, like the moveable window you're talking about. (That's what facebook messenger does too, except the "window" is by default just a single, small, fairly unobtrusive circle - very convenient.)

I added screenshots of the notifications window. It has the resume navigation button at constant place in the middle of the screen.

Unable to find Android WebView in Google Play store
A recent Chromium blog post contains a screenshot of a Google Play store page for the "Android System WebView".

I am unable to find this page. I have tried searching the Play Store on my Nexus 7 2013 device (which has Lollipop on it). Interestingly, this page does not seem to exist on the web at all:

It seems so.. I checked the package name of the APK, and it should be com.google.android.webview, so the Play Store link should be https://play.google.com/store/apps/details?id=com.google.android.webview, but it doesn't exist currently.

@AndrewT. And I don’t even have it installed as an app. If I understand correctly, the WebView should exist as a separate app on Lollipop. I don’t see it on my Nexus 7 2013.

It isn't listed on the launcher. Try checking on Settings > Apps > All > Android System WebView. Meanwhile, after reading the blog post, I'm thinking that the Play Store is only available for beta tester first. So, for public users, you won't see it live.

@AndrewT. Ah yes, I see it. I got version 37 (the newly announced beta is version 40).

@AndrewT. Confirmed on the web (but apparently with restricted access) https://twitter.com/passcod/status/567177405182140416

Update
Android System WebView's update is now released for public. Still, if you want to get (beta) update earlier, then continue reading:

As the article says,

If you're making use of the WebView in your app, becoming a beta channel tester will give you an early start with new APIs as well as the chance to test your app before the WebView rolls out to your users.
The first version offered in the beta channel will be based on Chrome 40 and you can find a full list of changes on the chromium blog entry.
To become a beta tester, join the community which will enable you to sign up for the Beta program; you'll then be able to install the beta version of the WebView via the Play Store. If you find any bugs, please file them on the Chromium issue tracker.

(Emphasis mine)
As of current, the WebView is based on Chrome 37, while the beta channel offers Chrome 40. Also, currently there is no update publicly available, hence the Play Store link displaying "Not Found". To be able to see page (and update the WebView), you have to join beta channel testing. The guide as provided on the Google+ community:

Join WebView Beta Channel community on Google+.
Sign up as a tester via this link.
Go to the Play Store page and ensure your devices are updated with the latest version.

Any way to set lockscreen notifications on AT&T LG G3 Lollipop?
AT&T appears to have completely disabled the lockscreen notification settings in their LG G3 Lollipop update. Anyone know of any way to change which notifications are shown, which are sensitive, etc.?

If you go to Settings -> Sound, and scroll down to the Notifications category.
The Lock Screen selection allows to choose Hide sensitive only, show all, or hide all. The Apps selection is a list of apps, which will let you select app behavior. However, the sensitive option is only available if you select "Show all notifications" option above.
Additionally it appears some applications have an invisible sensitivity setting that allows them to display information when "Hide sensitive only" is selected. I have several apps on my phone that display info/controls when the screen is locked, and I have it set to "Hide sensitive only" I found some discussion of the above information on this site, but nothing to explain the fact that some apps seem to default to nonsensitive, most don't.

Which stable and modern custom ROM can I install on Galaxy Tab 10.1 (GT-P7500)?
According to the device description at Cyanogenmod, the names for the device are:

Samsung Galaxy Tab 10.1,
GT-P7500,
p4.

The listed Cyanogenmod ROMs for this device are all "nightly", based on Cyanogenmod 10.1.
Aren't there more stable than "nightly" builds for this device? Are there ROMs that are based on a more recent Android version than Cyanogenmod 10.1 is (or this doesn't make sense for this device)?
I do not specifically ask for an official Cyanogenmod ROM, but it is the first place I look for a open-source custom ROM.

The dates on those indicate that they're not nightly, I'm guessing they're just not feature-complete for that device.  I'm not sure what you're looking for, though; if CM isn't providing stable builds, tautologically there are not stable CM builds.  ROM recommendations are off-topic here.

It Looks like there has never been an official supported stable build. That being said, you can try some of the nightly builds and hope they're stable.
Alternatively, you could have a look at some other ROMs such as ColorosOS, ParanoidAndroid, SlimROM (Check the compatibility, i've never used these on a tablet).

How can i change text vibration on my Galaxy S3?
I want to change sms vibrations on my Galaxy S3 but I can only change it for incoming calls.
Can someone tell how to change notification vibrations for sms on my Samsung Galaxy S3?
Thank you in advance.
PS : I am using Hangouts.
Edit : If possible, I don't want to install an app to solve my problem.

I have answered, but I'm not sure exactly what you mean by 'change' the vibration, I've given the answer to disable/enable them. As for changing the duration, type etc you can't unless rooted.

In Android each application can control the notifications itself. So if you turn off vibration for calls, texts will still have the option, and so on.
In the case of Hangouts:

Open the application.

Swipe from the left to open the menu (technically it's a navigation drawer).

Tap "Settings"

Tap "SMS"

You can enable/disable vibration here:

(source: techcovered.org)
If you wish to change the intensity/duration/pattern of the vibration you either need an SMS app that supports this feature or root access to your device coupled with a custom kernel that allows this feature.
Alternatively (though you specified you don't want to) you could try an app like Vibrate tools and see if that fits your need. I have not tested this app.

Ok thank you for your answer. So you are telling me that whithout a specific application or using a custom kernel it is impossible? edit : I am talking about intensity/duration/pattern of the vibrations.

@Maxime as far as I know yes. I'll keep looking for you though, but as of now the only way I can find is using S-Tweaks or something similar to change kernel settings.

I will try it, thank you very much for your time.

@Maxime no problem, happy to help! I've added a link to an app that might help. I know you don't want to install one, but it might be the way to go in this case.

After upgrade to android lollipop Moto G 1st Gen getting slow and lagging
My Moto G 1st Gen mobile is getting lag and slow after upgrade to android lollipop.
Please help me to get it fix.Thanks!

No need to reset the phone.Clearing cache partition should do the job.
How to clear cache partition on Moto G

I already did and did not help for me. I guess a factory reset is the only option left.

I don't think that factory reset might help if clearing cache didn't help. Anyway no harm in trying. But be sure yo backup your data before doing so.

The official guide to Moto G Clear Cache process is here.
But the only combination that worked to access the "wipe cache partition" menu was:
[Try to press and hold Power Button for at least two seconds and then without releasing the Power Button press Vol. Up key]

The instructions are outdated for Lollipop. It's now the opposite. On the Android in distress icon, you'll want to press the Power button a few seconds, then tap on Volume Up. I hope this helps.

I did the below method and it worked fine for me,

Do a backup of your phone
Do a factory reset.
Restore your phone

It should be fast now.

Does it really speed things up? I just though the phone couldn't really hand OS 5.0.

After Upgrading to lollipop, pattern lock issue, after unlock again screen locks , very annoyinig
I have upgraded my Moto G2 phone set to Lollipop version, After I did this facing issue with screen pattern lock/unlocking.
After I unlock screen, it goes lock again and this continues until I frustrated and I leave my phone untouched for sometime. Then I try after some time should be ok.
Very annoying and making life complex when desperately need to use.
Please some one share if you have face similar issue and resolved. Thanks.
Cheers
Sankar

Welcome to Android Enthusiasts StackExchange. Please be clearer asto what the problem really is...

Seems clear enough to me -- the device is repeatedly locking itself when it is unlocked.

Possibly, Remove lock screen option immediately when phone screen turns off, if its enabled.

I know this is dumb... but are you using flip cover. I had similar problem with my oneplus one recently and in the oneplus one forums they say that this is caused by the magnet in the flip cover. When you fold it back it falsely triggers the locking mechanism it seems. Although i agree to this i don't know how it wakes after sometime!!

How can i change app data location?
My default write disk is external sd card , my internal sd total space is 5.28 gb available is 4.66 gb my sdcard total space is 14.83 am using 16 gb available in sd card is 11 gb . my phone storage RAM is 1 gb (0.89) available is 65 mb .but when ever i downlaod any apps from play store its showing insufficent memmory like that. that time i goto settings > storage > phone storage > apps then i clear data of some apps i mainly used. my default write didk is external sd 11 + gb free . then i download apptosd app from playstore after also i am facing same issue . is there any option to change our app data phone storage to internal sd or external sd please. (my os is Android 4.4.2 kit kat ) ("Remember I can move app to sd card and internal sd ") by using of cm clean master app ) i cannot move app data to sd card or internal)

Application data is secure data stored on a partition with many restrictions.  Android does not allow you to move your data somewhere, where no such security for your data exists. If it would, malicious apps could easily steal user credentials, debit card info, etc. Therefore, Android does not allow you to move your applications' data.

But in my friend phone videocon quad z51 is kitkat 4.4.2 he don't have that issue all data is going to external sd or internal he dont have p phone storage option .when we go to settings > storage there we can seee internal sd and external sd only

On your device:

Go to your phone settings → Developer Tools.
If you don't see the developer tools options, go to Settings → About phone and tap on the build number seven times and then you should get the developer tools on your settings menu.
Turn on USB Debugging from Developer tools.

On your computer:

Make sure that you have the latest device drivers (I'm assuming you're using Windows OS. This isn't necessary for Linux or iOS).
Download the adb (Android Device Bridge) tool. It usually comes with the Android SDK, but you can find it here.
Connect your device to the computer using a USB cable.
Run adb from Command prompt using one of these commands:
adb shell pm set-install-location 0
adb shell pm set-install-location 2  # alternative command

The first command sets your install location for phone memory. The other one sets to external SD Card.

ok you can do it efficient, if you have root permission..
now i assume you know what is rooting.. if not, please don't follow this answer..
there are two ways available, easy but hard way and hard but easy way..
1) easy but hard way, install xposed and download a module name called "XInternalSD", enable it and restart your phone.. now go to that app and check "enable for all user apps" option.. and thats all.. its done.. from now on you can install any app or game, and it will directly installed to your sd card.. no more "insufficent space" warning..
now why this method called Easy but the Hard way?
its simple, xposed is a system level hook.. so if you dont know what you are doing, it will brick your device..
2) using link2sd app.. download it from playstore.. and go to options and set "install location" to external.. thats all.. but this method doesnt force all apps to sd.. if an app requires to be installed in internal, it will leave as it is.. optionally you can format your sd card to make an ext partition for installing all apps on sd card.. thats all..
note: these two methods needs root permission..

In the samsung J1 ace goto settings/storage/sdcard/three dotmenu to set it

Huawei Y330-U11 bootloop
My device, Huawei Y330-U11, is stuck on a bootloop.
Recovery isn't working. The only possible mode is "Fastboot & Rescue" mode, which needs the phone to be connected to the PC. But, the phone is not being detected.

Try downloading a stock y330-u11 firmware from Susutun then extract the zip. Read fully the instruction given. Once you've got the SP flash tool, check the scatter file and the uboot. Choose Recovery and boot. Then hit download. Turn of the phone and pull out battery. Reinstall the battery but don't power on. Connect the usb while holding vol up/down. The progress bar should start.

An app on my phone has suddenly disappeared but when i look in play store,it is already installed and can be opened
I just saw that an app which i had on my phone suddenly went missing. I thought I might have uninstalled it by mistake ,but when i looked for it on the play store, it was already installed and i could open it from there. But on my phone it is not there. What can i do.?

is your phone rooted, or do you use launchers?

Go to your phone>settings>apps>all apps. is your app there?

If you're using third party launchers like go launcher or apex launcher, it is possible to hide an app and make it invisible in the app drawer. If this is not the case, look for it in the apps section in your settings. Or simply re-install the app from the play store. And turn on "place the app on your home screen" in the play store settings before you reinstall just in case, so that you know the app icon is visible now.

How repair sd-card locked read-only mode? Its probably file system error
I have alcatel onetouch pop with jellybean 4.2.2. I put into 32 Gb sd hc card. Card did not work correctly.  Sometimes (specialy when i tried write more that one file) card has blocked with something like read-only mode. In that sitiation I used to connect my phone to computer (win 8.1) and run disk checking from properties. thats usuly had fix problem. Now my friend have switched on developer mode on my phone and my computer stoped seeing phone. I can't switch off dev mode, and I don't know how to repair sd card. Sorry for my English. Anyone can help me?

First, stop letting your friend mess with your phone. :) Dismount the card on your phone (or shut the phone down), remove the card, and use a compatible USB card reader to mount the card on your Windows computer.
At that point I would strongly suggest you copy off all the files from the SD card to your computer. After that reformat the SD card, using either the official utility at https://www.sdcard.org/downloads/formatter_4/ , or by putting it back into your phone and having it reformat it. (I strongly suggest the first option!)
If you encounter problems with any of this, chances are your card has been damaged beyond repair, perhaps by the flash memory write cycles being exhausted. Grab what you can and get a new one.
All of this, by the way, assumes you really have a micro SD card, or a full-sized one that you've verified the write lock tab is set properly.

I formatted the card as FAT32 and didn't work. I uninstalled the application (for access rights). Nothing.
What worked for me WITHOUT rooting the phone. Format the card from the phone, not computer. If you don't find the formatting facility then you can format the card as NTFS. Then insert the card. The phone will notice you it is faulty and give you the possibility to format it. After that it should be solved.

Pasting an image on Word app failed, copying its link instead
I am unable to copy an image from internet and paste it on Word documents. When I copy the image, the image's link is copied to clipboard and when I paste it on Word document the link is pasted.
Can anyone tell me why am I unable to copy image to clipboard and how can I do so?
I'm using Motorola Moto E on Android KitKat 4.4.4 if it matters.

I am not sure but maybe it depends on where you copy from. Also there might be some restriction on the file types you can copy (though images should be allowed).

@GiantTree I tried copying image from a webpage. I have tried copying with gif and jpg file types.

Does it say "Copy image" or "Copy image url"? There's a difference between these two ^^

@GiantTree It says Copy Image.

@GiantTree Added Images to the question.

I just tested it on my phone. It seems like word does not allow pasting anything but text. Maybe try another office app or paste it on PC.

@GiantTree Tried QuickOffice but didn't work. Any other office app suggestion.

My Navigation Keys and Status Bar are lost!
I'm using Nexus 5, Lollipop 5.0.1 (rooted), no custom ROM, and Franco Kernel. I was changing my Nav Keys by an app. By mistake, I hit restore and then after the reboot I found that my nav bars are gone and even the status bar!
Now I literally have to reboot to switch in apps. Please help!

Which app did you use?

Dirty flash Lollipop over itself, meaning don't wipe anything. All your data will be intact. If your using Xposed framework, it will have to be re-enabled. If necessary you can wipe cache.
