How to Have 2nd Step Verification for Making Calls in 6.0?
I would like to use 2nd Step Verification always for Making Calls. I can use a second device to get those codes; etc second Gmail account; or a similar encryption device as used by banks. I do not want to use the same device to get the code and call.
The current layer of protection is not enough in Android 6.0 System.

Problem: anyone who has access to your phone can make a call. This is a serious problem. Reasons and logs about them, I have provided private to developers of bottle necks.

Motivation of crackers in end-to-end. If the cracker can get through the protection layers, they can kill end-to-end applications for some reason. Experienced compromises in Signal.

How can you Have 2nd Step Verification for Making Calls in 6.0?

Sideload Factory OS via ADB
I have a nexus 6 which failed when updating to 6.0.1. I can no longer boot into the Operating System as the /system partition is corrupt. I ran a factory reset - but this didn't fix the problem because factory reset only clears out the /cache and /data partitions.

Since I am able to get into the bootloader and android recovery I was wondering if it is possible to reinstall the OS via ADB. I've searched around it it looks like ADB can only be used for installing updates/programs while fastboot can flash the /system partition with a factory image. I'm unable to use fastboot because the phone is not rooted. So, is there any way to restore the factory image of the OS via ADB on a non-rooted phone?

Is auto-sync really the biggest battery killer?
I have been digging the archives for eternity to find that Location Services and Auto-sync (assuming we ignored other factors such as Bluetooth etc -- because my focus is mainly about auto sync) are extremely battery hungry.

Although, i manually toggle the switches (GPS, BT etc) based on requirement. I have paid enough heed to notice the battery gain and drain caused by auto sync enabled and disabled.

I have read somewhere people claiming innocence of autosync. Basically, Their idea is  that it doesn't constantly push all the data from server to my phone and vice-versa. instead, there is a thread meant to ask the server if there's something new (and events are created based on the responses).

So, shed some light on:

1) is auto sync really causing  the depression to my battery?

2) what does auto sync really do (perhaps a geeky explanation please) ?

3) how many minutes/hours am i actually gaining or losing while leaving it ON or OFF ?

Repair bricked Nexus 9
During an OTA update the tablet went into a boot loop.  I let this continue a few times until I was fairly certain it wasn't going to resolve itself.  I never had a reason to unlock the tablet or use ADB so I never enabled those options from the developer menu.  I am able to see the device from a PC using fastboot, same from my linux laptop.  When I attempt to flash anything I get permission issues, same with the oem unlock command.  ADB devices shows nothing, so I'm not sure if there's a way to update or sideload something or if I'm just screwed.

I've done a good amount of research and found people who have said they were able to sideload, but I'm not sure if ADB is like the unlock option -that it has to be enabled from inside the OS? (Aside: Why would they do this?!?)  Unlocking isn't an option it seems, so are there any other workarounds people are aware of?  Is there a way to unlock or enable ADB from the recovery menus?

Note: need help Nexus 9 stuck in endless reboot loop does not work for me as fastboot sees the device, but ADB does not.

Any help would be greatly appreciated.  This is the worst flagship device I've ever used and seriously has me considering an iPad...  With much angst.  I just can't believe a device that is less than 2 years old that gets bricked on an update, that I would have to pay to repair and not have a tablet for weeks.  Just not acceptable.

How to search for a specific email in a long thread in GMail for Android?
My inbox is full of long conversations (threads), each of them often having 50 or more emails. I find that the search function in the GMail app on Android is virtually useless with an inbox like this. Is there something I'm missing?

A bit more context: on the desktop web UI, searching for a specific phrase yields results that are conversations. Clicking on one of these opens up that conversation, expanding only the emails that match, as well as highlighting the matching parts. This is good.

On GMail for Android, the same search query yields the same results, and tapping on one of them opens that conversation, however, only the latest email in the thread is ever expanded. There's no indication which emails in the long thread actually contain matches. I need to expand each one in turn and read them myself to look for matches, which is of course ridiculous.

Note that refining my search won't help, here. The correct conversations are found, but that's not granular enough. I need the precise emails that match.

So again: what am I missing, if anything? Is the GMail app for Android capable of actually giving me precisely relevant results?

How to remove root backdoor on an Allwinner device?
I read on The Register that a root backdoor is triggered by writing rootmydevice to the special file /proc/sunxi_debug/sunxi_debug. That gives the current running process root privileges. If that file is present on your device or single-board computer, then you need to get rid of it. This is the code that checks for the magic write:

```<code>if(!strncmp("rootmydevice",(char*)buf,12)){
    cred = (struct cred *)__task_cred(current);
    cred->uid = 0;
    cred->gid = 0;
    cred->suid = 0;
    cred->euid = 0;
    cred->euid = 0;
    cred->egid = 0;
    cred->fsuid = 0;
    cred->fsgid = 0;
    printk("now you are root\n");
}
</code>```

I have questions:

I have a Fusion5 tablet (which is rooted) manufactured by Allwinner with sun8I chipset using kernel 3.4.39. The file /proc/sunxi_debug/sunxi_debug is zero length. If the code is present, which file (if any) would it be in?

When using Terminal Emulator, I do rm /proc/.sunxi_debug/sunxi_debug, I get "Permission denied". sudo su gets "sudo: not found". How do I delete the /proc/sunxi_debug/sunxi_debug file?

Weird volume behaviour in Android 6.0.1
My wife's Nexus 5 recently started behaving very weirdly.

For notifications, it always think that it's in silent mode (i.e. it vibrates and doesn't play a sound). This happens regardless of the actual volume settings. All other sounds seem to work properly (ringtones, in-call volume, etc.)

Also, when she presses volume up or down, it adjusts the in-call volume instead ringtone volume.

I have tried rebooting, and I even tried deleting the cache (as described here - https://android.stackexchange.com/a/139739/165076) but nothing seems to help.

So I do that, but it doesn't seem to take because a day or two later, it informs me again that an upgrade to 4.3 is ready. I look and I see that the current version is 4.2.2. What is wrong?

Don't know if this matters, but before the reset, it was rooted, and so after I assume it is not and that's fine.

  Restrict market updates to WiFi network

I'd like to avoid using the expensive 3G data bandwidth for app updates.  Is there an app or something that will restrict updates so that they can only happen over wifi?  Alternatively, is there a master switch that can disable updates and then re-enable them?  The best solution I've found so far is to uncheck the "automatic update" box on each app's Market page.  This is tedious at best, and I'm not sure if I would get notified of available updates or if I would need to periodically check every installed app's Market page for available updates.

问:
How do carriers block tethering?
I have two sim cards with data bundles from different carriers. One is working fine with (WiFi) tethering, but with the second SIM card I cannot use tethering.

Searching online I saw that tethering can be blocked by blocking browsers' user-agent headers. Alternatively using torrenting software headers and other PC-related application headers. In my case, I cannot even ping 8.8.8.8 from my laptop using the second SIM card, while I can from my android using a terminal emulator.

Tethering problem with the second SIM card existed from the beginning. Perhaps I just loaded one web page with it (or it seemed like loading, but in reality browser retrieved it from its cache).

So in my case, how does the carrier block the tethering?
Of course, the purpose of this question is to bypass this block.
There is also the possibility that there is no block at all, but something else is causing the problem, but I am baffled because this should happen with both SIM cards, right?

EDIT (solution):
After paying $20 to my working SIM card to google around, I solved it myself... I discovered that USB tethering was possible with the second SIM card. I found this strange, and checked (Android 6.0) the 'Mobile data > Mobile networks > Access point names > ''carrier name'' Internet (or sth similar)' for both SIM cards.

This is a long list of settings (Name, APN, Proxy, Port, etc...). The difference was in the 'APN type'. In the working SIM it was filled with 'default,dun,mms,supl'. In the "faulty" SIM with 'mms' only! So I wrote 'default,dun,mms,supl' and now tethering works fine with a WiFi hotspot.

Fastboot "waiting for device"
I have an galaxy s4 i33 that I need to have upgraded for work (or buy a new phone.)

On both windows and Linux I can type "adb reboot bootloader" to open the bootloader.

However, in windows:

-Odin Crashes.

-ADB can only find the device when it is turned on normally

-Fastboot says "waiting for device"... forever.

-(Did not try fastboot devices in windows.)

In Linux:

-Fastboot can NEVER find the device.

-ADB can only find the device when it is on normally

'lsusb' looks like this when the device is turned on normally:

```<code>Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

How to fix mobile hotspot?
Shortly said, my mobile hotspot doesn't work.

I can connect my laptop to my phone but I can't get on the web. Mobile data on my phone works flawlessly.

What I've tried:

Putting my SIM card into another device

Connecting other devices to my phone's hotspot

Connecting my laptop to other hotspots

Putting another SIM card into my phone

All of the above, except the second point, work.

I was thinking it's my phones fault, but the last list item confuses me.
Why does it work, when I insert another SIM card? I didn't change any settings. I even let the hotspot run and just switched SIM cards.

I already asked my mobile provider if there are any special settings, either on my phone or on my laptop, I have to make. But they don't know about anything.

Has somebody ever encountered a similar problem or has an idea what else I could try?

I have another problem which I thought is somehow connected to the above one:

I rooted my phone and tried to unroot it again for OTA updates. But the phone doesn't properly restart. It always boots to the bootloader and I can't get into recovery.

But since my hotspot works with a different SIM card I don't think these two problems are connected.

I think the cause of my hotspot not working is the special constellation of my phone with my SIM card.

Can't install TWRP LG Optimus G
This thread of mine is partly copied from XDA.

I can't get through following issues. Phone's firmware is full vanilla since the very beginning - only updated from Jelly Bean/ICS to 4.4.2 with OTA.
I want to install TWRP Recovery and then try some custom firmwares. I started with making a backup of IMEI/NVRAM by MTK Droid R&T just to be safe.
I can't, IMEI/NVRAM button is greyed out. Log:

 --- ERROR  :  --- TotalBytesPerChunk Not Found. Set default Page/Spare=2048/64 !!!
 --- Unknown ROM structure, backup NOT possible!
</code>```

I've looked for solutions. They suggest e.g. searching for MTK app from different source. It doesn't help.
Setting up a root is also a trouble. I tried to use the simpliest, well known method within the reach based on Batch script.
Log:

Press Enter after making the change.

Command like adb reboot bootloader just restarts the phone. It starts as usually.

Then I tried reinstalling KitKat with OTA hoping that phone will let me do more then. While installation phone got into Download Mode, then it rebooted and - what is strange - there was no changes at all. No factory reset occurred.

At the moment I'm helplessly begging/crying for help. Thx for any help/suggestions.

So, I checked my In Settings > Apps > Downloaded and found 2 unknown apps & deleted them. But somehow they appeared again. It's good to say that my device is rooted. I then went to system/app folder and found those 2 of them:

.
2.apk name: com.system.cap.qs.iupdater.apk

package name: com.android.updater

I tried to delete them but failed though I'm rooted. I faced a new problem at night when the original systemUI & Android updater stop working. I think those unwanted culprit apps are trying to override the original system apps because their package name matches the system apps.

Blank screen boot loop on SM-T211
I have a Samsung SM-T211 (India) tablet and am using it for 2 years. I have rooted it using ODIN and TWRP (android 4.4.2) based on online tutorials and it is working fine. Couple of days back when I connected to samsung Kies, it showed that there is an update. I have read in internet that updating through Kies only makes your OS updated resulting an unrooted device which I thought is OK.

Kies downloaded the program and installed on the TAB. It said the TAB would reboot after install. The TAB didn't booted to samsung logo instead entered a blank screen boot loop(I can see a dim light on screen).It is rebooting itself into blank screen. I have tried to enter DOWNLOAD mode but no key configuration is working. The TAB is not even connecting to PC. I have reinstalled Kies and USB drivers still no luck with detection.

Its been a week and I have observed the following :

a) Some times it completely shuts off only enters boot loop when connected to wall charger

b) couple of times when tried to enter download mode, a blank screen with four lines showing ODIN, OS- CUSTOM appeared. It only happened twice randomly and I couldn't capture the image.

I also removed and reattached the battery connector according to  some tutorials with no result.

I have given it to samsung customer care, they said there is a display problem which I don't believe as it is flawlessly working for over two years and I can see OS status as custom briefly (as mentioned above)

I am pretty naive to android(and its terminology) and cannot come with own solution however I can follow any guidelines if given.

Please provide me your suggestions to solve this issue. Thanks in advance.

Is it unnecessary to unmount twice?

Before unplugging the tablet, I usually do "Eject" in the desktop OS X/GNU/Windows file manager, and then click "Turn off USB storage" on the display of the tablet.

Is it alright to:

Just eject the drives on the desktop, and then physically plug out the cable?

Intermittent internet connectivity problems on Samsung Galaxy S4
So last night Chrome on my Galaxy S4 suddenly started refusing to load websites while connected to the exact same WiFi network that works flawlessly for two different laptops and a PC within my home network. Even using two different mobile providers' data networks, or the WiFi at three different friends' houses doesn't seem to work, so I doubt this issue has anything to do with my internet connection/s.

The strangest thing about this whole situation is that Chrome will search Google fine, and the Play store app will also search its catalog, download updates and even install new apps without a hitch, but pretty much every time I try to connect to a non-Google-owned server, the connection status bar fills about 10% of the way and hangs for 30 seconds before timing out.

Has anyone experienced anything like this before?

EDIT: This now happens at least once per day; often 3 or 4 times per day. Restarting the phone seems to be the only way to get connectivity back, before it drops out again a few hours later. Google apps (Play Store, YouTube, Maps, etc.) all work fine without a restart but other apps and websites refuse to respond. Please help; this is driving me crazy!!

Turn off vibration on apps for nexus
Is there any way to turn off the vibration on the nexus 4 phone? I would like to open up the phone and rip out the vibration device it is annoying me that much.

For all calls and SMS there is no vibration. But for the Apps there is vibration. However I would like to keep the notifications for the apps, in the sense that I would like to have the visual pop ups that come on the screen. They are great! But it seems like it is almost impossible to decouple the associated vibrations that come with it.

If I go to the app notifications it either gives me the option of completely getting rid of the notifications, or having the notifications with vibrate. Only WhatsApp has the little cog wheel at the top which gives me the option of turning off vibration as well. All other apps don't.

Otherwise can someone tell me where this vibrate thingy is so I can jam a screwdriver into it or pour acid into it?

It's pretty simple:

If I turn off the phone's screen and then connect the wall charger, the power supply draws ~6W from the wall, and this doesn't change if I keep waiting.

If I connect the wall charger and then turn off the phone's screen, the power supply draws ~10W, and I hear a very slightly audible high-pitched noise from the power supply the moment I turn off the screen.

If I turn on the screen again, it goes back down to ~6W, but once it turns off it goes up again.

I have two questions:

What is causing this?

If it is intentional and not a bug, then what is the rationale for the cause? Is this well-known?

The ROM is CM11S 05Q.

(Yes, the charger & cable are the OEM's, and yes, I've actually measured the current.)


问:
Nexus 9, no recovery, no USB debugging, OEM locked in Settings
I've got a pretty complex problem.

At the moment:

Nexus 9 WiFi Tablet, USB Debugging not enabled

Normal Startup: Android laying on the floor

Startup with Power+Volume Down:

Fastboot Bootloader LOCKED

Recovery doesn't start

Factory Reset crashes as well

fastboot oem unlock → permission denied

Question

I want to know whether I can completely reset/wipe my device through fastboot or whatever I can use to do it.

I am not able to fastboot boot boot.img or something similar because USB Debugging and OEM unlocking aren't enabled and I can't start the device to do so.

The device has no microSD card slot.

EDIT:
When I choose HBOOT → RECOVERY I get the Android laying on the floor with a red triangle.

It is the device of a colleague of mine. He restarted the tablet and it happened. Don't have more information.

[SOLUTION]:

I could find a solution for my problem.

adb.exe sideload volantis-ota....zip

With the help of an OTA-Image, I could reset and recover the tablet.

CWM recovery Nandroid Backup
Is there any way to create a Nandroid backup inside CWM recovery, by using the /cache/recovery/extendedcommand file?

(This file supports all the commands a normal updater-script file supports inside a flashable zip).

Edit:
I know it's easier to do this with use of TWRP. However, I am developing an app that takes backups automatically. I want it to support both CWM and TWRP if possible.

问:
How to emulate camera input in Android? (To activate Whatsapp Web)
I have an Android device without a camera and I run Whatsapp on that device.

I want to activate Whatsapp Web from this device. Unfortunately, the only way to do this is to scan a QR-code, and I can't do that as I have no camera.

So, if I just could emulate camera input, that means use an image or video file of the QR code and have that be taken by the OS as camera input, then I would solve the problem.

This is doable on Windows. I'm sure it should be doable on a rooted Android device as well, especially if we can use Xposed Framework.

But the question is, does anybody know how to?


问:
Microphone volume randomly reduced
I have a Lenovo A6000 phone, Android 4.4.4 is installed. I have Dolby off and I don't use any app to control volumes (not even skype, viber or facebook messenger), also, the phone is NOT rooted.

Sometimes the microphone's recording volume becomes so low, others can hardly hear me talking. It happens randomly and If I restart the phone, the volume becomes correct again.

I can always test If It is correct or not, because I have a similar sound recording software preinstalled on my device like this:

And I can use the sound sensitivity meter to see if it is high enough, sometimes it becomes so low that I cannot get it higher than 10% when I am talking normally.

I guess It is not a hardware issue, because a restart solves it instantly. Is there any app that can interfere with the microphone volume?

Edit.: Some people say that If I update to Lolipop it solves the issue, but I don't have any software updates available.

Mobile Data icon and WiFi icon are showing exclamation mark even though internet is connected
I'm having OnePlus 2 with latest OxygenOS 3.0 Beta. I live in UAE. Recently I started getting exclamation mark with connection icon, whether using mobile data or Wi-Fi. I suspected of issue with beta version. But when I went outside the country, I didn't face the same issue. When I came back I started getting the same issue again. This leads me to suspect it's a carrier related issue, not an issue with beta OS.

I tried resolution mentioned in below post already. They are not helpful.

Apparently my OnePlus 2 is not detecting internet connectivity, but allowing me to browse sites and use every services, which require internet connectivity.

Google Now reminders will not store the hour
I can reproduce this issue consistently each time.

Using Google Now to store a reminder (either via voice input or by keyboard) will correctly store the title and the date, but not the hour.

If I use the voice input, it recognizes the hour set properly and even displays it to me. After that, it asks if I want to save the reminder, I say 'yes' and it seems to be stored properly.

But when I go check it, it has lost the hour and it is set for the entire day.

Is this a known issue? Is there a fix? Can other reproduce this?

Why doesn't my computer list Android devices in Device Manager, or detect my Sony Xperia Play (R800)?
I have an ancient Sony Xperia Play that I am trying to root. However, I can't even get it to show up on my computer.

It's possible that I accidentally deleted my drivers by running an unroot script. However, since then I've tried the following:

enabling mass storage mode, debug mode and unknown sources on my phone;

installing Android SDK, the usb drivers, and multiple versions of abd;

removing superfluous drivers (but I can still run "Minimal ABD & Flashboot"...?) & installing Koush's adb driver.

Absolutely no option for "Android Device Bridge" (or its various aliases), nor the phone itself, shows up in the device manager when I connect the phone via USB. When I run abd devices, no devices show up. I don't really know what I'm doing, any advice as to what could be the problem?


问:
How can I disable (only) the rear facing camera?
I have a Droid Maxx running Android 4.4, but the rear facing camera has a problem. I tried replacing it once, and it worked for a few minutes, but went bad again. The front facing camera works fine.

Because all the apps tend to default to the rear facing camera, I end up not being able to use the camera at all. (The rear camera just freezes the app when it is activated.) It would be really nice to be able to use the front camera, since that one still works fine. (If I can find a way to activate it before the rear camera locks up the app.)

I found several apps on Google Play that will disable all the cameras, but I didn't see any that let you disable just the rear camera while keeping the front active. Is there an app or a setting that would allow me to do this?

The phone is using the stock Verizon bootloader and is not rooted. Thanks in advance for any tips in this regard!! I love the phone, I just miss the camera.

How to force apps to use default notification sound or vibration?
Every other app has its own notification sound or vibration. Some apps have unpleasant notifications sounds or vibrations so long I think I'm receiving a call.

I like my life simple: I want all apps to use the default notification sound and vibration I selected in my system settings.

How can I do that?

Dial between two emulators does not work
Today, I had installed the latest Android SDK and created two emulators (Nexus 6), I then tried to dial from one emulator to another.

Based on Make incoming call in Android emulator without command code,
I just dial 5556 from the emulator of 5554.
But there is no receiving call in emulator-5554.

The name of the second emulator is emulator-5556 so I guess that it is correct to just dial 5556, right?

Restoring SMS database in Marshmallow

Keyboard emoji not available in some apps
Google updated their keyboard app yesterday, a few welcome tweaks, but something seems to have broken for me.

In some apps that are badly built, I've no longer got access to emojis. If I long press the enter key, I should be presented with 3 (teal circle) options here above the enter key - instead I see only two. Emojis are missing.

They're in the bottom left key section I hear you cry! Nope, these are just plain text smileys, full image emojis are nowhere to be seen in this case.

Most other apps I've used do indeed appear to work properly and have the full functionality present.

It's worth noting that the emojis in the app I'm seeing this did work before the update.

Is there anyway to fix this, like forcing the same layout for any app?

And no, I don't want to download another keyboard, I really like the Google stock keyboard, this is it's only flaw right now.


问:
Generate all gallery thumbnails 'at one time', not 'on demand'
Context:

Hello, I am an amateur photographer and I recently moved from an old iPad to a Galaxy Tab S 10.5 with custom rom, Android 6.

On the iPad the thumbnails were created while importing photos from iTunes, and even at the first time I opened the gallery everything was there.

Now I just copy a Photo folder into the root of my microSD card and I use QuickPic Gallery (but any other gallery is the same) to view the photos. I have 2-3k pictures and every time I open a gallery for the first time i see only black squares and they slowly appear, same story when I open a photo full-screen.

Short story:

Pictures that I copy into the microSD card have no thumbnails.

I don't want to wait for the creation on-the-fly when I open a folder or manually open everything after copying so the next time will be cached!

How can I trigger the creation of all necessary thumbnails just after I copied my photos?

Thanks

问:
How to provision an Android phone automatically?
tl;dr: How can I write a short declarative description of the state I want my phone to be in, and then apply it to a phone?

After a factory reset or hardware change it's always a pain to get my phone back to a usable state. At the same time I don't trust any random third party service to store my settings:

I don't have fine grained control over what they actually store. They may sell or leak that information without my knowledge or consent.

They may be incompatible with future hardware/software, and I won't know until I try to restore.

They may be incompatible with my configuration (try updating Android after rooting your phone, for example).

They may at any time be shut down.

I'll bet none of them allow me to retrieve the data in such a way that I can migrate to another service.

Setting up this sort of thing for your own PC requires very little technical skill and a little time - I've already set up a repository to provision my own desktop and laptop. However, I've no idea how to do something similar on Android. I can't see any mention of a Puppet client, and I don't know if it's possible to provision a device in any sensible way without installing a custom kernel or rooting it.

问:
Do apps need to be started once to receive background data
I just recently bought my first Android based phone (Samsung Galaxy A3).

One thing I noticed (or maybe imagined noticing?) is that I appear to only receive notifications (like a new message in WhatsApp or a new email) if that app was previously started (and thereby listed in the "Running Apps" screen).

Is that true? Would that not defeat the purpose of notifications? I tried searching for settings that would imply such a behaviour, but couldn't find any.

Restrict background data is turned off

WhatsApp/Gmail, etc. all have background data enabled

Sync (from the top shortcut menu) is enabled

Accounts/Sync settings for WhatsApp and Google Accounts are enabled

I have a DataUsage warning at 400MB (reached) and a limit at 500MB (not yet reached)

Network connection is set to LTE/3G/2G (automatic) and I am in 4G currently

Thats about all I could think off / find... Is there more to check?


问:
Can the Chrome logo icon in the notifications bar be changed to reflect the site delivering the push notification?
I've heard plenty about the power-draining properties of Facebook's app - I'm obviously as keen as the next smartphone user to find ways to save battery power. Of course, others have concerns about the app's all-consuming permission set.

One popular solution to these little issues for a lot of Android users seems to be to bin the app entirely, and set up push notifications from Facebook's mobile site using Chrome for Android. So, I'm giving that a go.

The notifications work like a dream, but - as I could have expected, really - it's the Chrome icon that's displayed in the notifications bar, not the Facebook one. It's pernickety of me, but I'd really like it to be the Facebook icon that appears in the notifications bar.

Through reading this question, I've already found out about the Notification Toggle app, which supposedly lets you change notification icons. I've yet to download and play around with it, but in theory this will be a good enough solution for my needs - I've no plans to receive push notifications from any other sites, so superimposing the Facebook icon onto Chrome notifications will do the job just fine.

However, it doesn't strike me as unreasonable for a user to receive push notifications from two or more different sites - in which case, it would be useful for notification icons to reflect the site for which notifications are being received. Maybe by pulling through the site's favicon for use in the notifications tab? Or failing that, it would be good to be able to change icons manually by targeting the site, and not just any and all Chrome notifications.

Does anyone know if something like this is possible? I don't know if being rooted or not would make a difference in this case, but for what it's worth my personal setup is an unrooted Honor 7 using Nova Launcher.

Tether laptop to Android Pulse Secure

I imagine there is some way to route my laptop's connection to the VPN via my phone without using cellular data.

When I disable cellular data and enable USB tethering in settings, the modal hangs, presumably because it is trying to check with the phone company over their network for "permission".

How to install hindi font in kindle 6.4.5 without rooting it?
I have Kindle whose version # is 6.4.5.
I have installed whatsapp in it. But the Hindi messages will not appear correctly , it will be shown in rectangle form. I have tried to install hindi font as mentioned below

Before installing fonts you need to make sure that those fonts meet
  the minimum requirements, such as:

```<code>      a. The format used is TrueType or OpenType.
      b. You need to have 4 variants of the files: regular, bold, bold
          italic, italic
      c. The file structure should look like this: [name]-Regular.ttf ,
          [name]-Bold.ttf ,[name]-Italic.ttf, [name]-BoldItalic.ttf
</code>```

After you make sure they meet these requirements you need to take the
  following steps in order to use your custom fonts:

Connect the Kindle to your PC;

Use the computer and browse the content of the Kindle and create a folder in the root of the drive : fonts;

Copy your files in that folder, following the structure given above;

Start Calibre and go to Kindle Configuration > Modify Kindle Settings;

From the Font Family, choose the fonts you need;

Save the settings and wait for the device to reboot.

But get no success.. Please can any one help me

问:
How to know which installed app can show before my native lock screen?
My question stems from this question about an app showing a custom view (with ads) before the lock screen. As of now none of the answers there provides a technical way to filter out the concerned app on your own, without relying on app reviews or a list somewhere on web -  in short, a complete dependence on the experiences of others. In such cases even if the solution is one query away from web search engine I prefer to come up with a technique to hunt down the cause of the effect through means already available in Android.

Anyhow. Let's come to the point. How do I find out which installed apps are potentially capable of showing themselves before my lock screen?

With limited understanding I earlier speculated that an app would need the permission to draw over other apps to show before lock screen. However, my experiments with ES File Explorer v4.0.5.2 and with continuous monitoring of appsops service concludes that ES File Explorer didn't make use of SYSTEM_ALERT_WINDOW (I had appops deny that permission to the said app), yet, it displayed that famous quick charging screen. Swiping it away even dismissed my unsecured lock screen. That said, using dumpsys activity activities and dumpsys window windows I immediately found the activity com.dianxinos.lockscreen.LockScreenContainer responsible for that screen.

I'm aware of certain window manager flags supposed to be used in source code and  helps an app to show before lock screen and that's all is needed. No special permission or an attribute in manifest is needed so it becomes very difficult as well as inefficient to find potential apps until the effect comes into action, forget about symptoms.

True, that I can narrow down the hunt to apps which:

can receive data from internet (to show ads);

listens to ACTION_POWER_CONNECTED (not necessarily needed; may not be relevant in future);

listens to ACTION_USER_PRESENT (not necessarily needed);

requires SYSTEM_ALERT_WINDOW (may or may not be needed);

requires android.permission.WAKE_LOCK (not necessarily needed);

requires android.permission.DISABLE_KEYGUARD (not necessarily needed).

Yet, none of them, used as a parameter alone or combined, satisfactorily solves the original problem I have.

I would like to stress that I'm looking to filter out apps potentially capable of displaying something before my lock screen. I'm not asking for what is this lock screen with ads and how do I remove it?

Note: if it matters: I'm using stock and rooted Android 5.0, 5.1.1 and 6.0.1 on Nexus 6.

Edit

To avoid confusion: By before the lock screen I mean anything that is shown to user before the default lock screen is displayed whenever you attempt to wake up the device. As Izzy noted in a comment, "it places itself in front of the lock screen" might be a better phrase, but I avoided it since it appears to me to be corresponding to an overlay.

How can I enable the "Add user or profile" option on Lolipop (Asus Zenpad S 8) - fw.max_users?
Hi I have been setting up Parental Control for a 9 year old kid on an Asus ZenPad S 8.0, which has Android 5.0 Lolipop installed.

I created a restricted account for him but tinkered trying to remove the guest option as he could bypass security by creating a temporary guest account.

In the end a part from install some aps like Time Limit, Screen Time, Internet Security, Family Time... I didn't actually do much as at some point after trying many different tools () I realised the tablet had to be rooted in order for the guest account to be disabled as described in this article http://slashgenie.com/how-to-disable-creation-of-android-guest-accounts-on-lollipop/
I decided not to root it as I am new to Android and I understood this voids the warranty and can create a "brick" :(

The strange thing is that now with the main owner/admin account I can create guest accounts but I can't create new accounts (I want to create another restricted account for his brother).

The "Add user or profile" option is disabled. This guy seems to have a similar problem Why can't I add any more user?
But I only have two users the admin + the kid. Maybe with my tinkering of file explorer apps and sql editors I did actually manage to reduce the number of accounts to 1 (my original intention with fw.max_users=1)... but this should have show up on the file build.prop, which it doesn't, and how could I do that as my device is not rooted!?


问:
2 years old Zenfone 5, how to control battery use?
Sorry for asking about such an overdone subject.

Question is, I have a (as of now) 2 years old Zenfone 5.

Android 4.4.2, ZenUI, not rooted (yet), Energy Management off, stock charger.

Configurations include minimal brightness, only antenna is constantly on, and I have touch feedback from Dev Config on.

For the last 3 months, my battery seems less able to take on Wi-Fi, and Google's apps specifically.

For a measure, I already had my battery last little less than 40h, by not using any Internet whatsoever. Now, I start using Wi-Fi and it drops at a rate of 0.3% per min. I remember a time I could use it the same way, and it'd last at least two hours more than now.

Apps recently downloaded include Piano Tiles 2, Avast and Malwarebytes, both of the latter I already uninstalled. Piano Tiles 2 force-stopped.

As of posting this question, I've force-stopped most non-crucial apps beyond aforementioned and turned Energy Manag. back on, to see if anything change. I'll report back any improvement.

Thanks in advance!

How to have an App Factory wait for 30 minutes before performing the next action?
I learned that app factory apps should run in the background no problem, but if that's the case, I'm wondering why the simple app I created randomly restarts when it includes a 30 minute waiting action. When I take it out, it works (starts does its job and stops in a matter of a few seconds). But I'd like it to do another action after 30 minutes and that's when it keeps restarting several times during that 30 minute period.

ADB: how to use it over TCP/IP during USB accessory development
I'm using an evaluation board from Atmel (based on SAM D21 Cortex-M0+ MCU) for developing a custom Android USB accessory and related app.

I'm new to Android development, but I understood I need ADB connection for debugging: breakpoint, step into, step over, resume, and so on.

ADB is generally over USB, but the USB port is connected to the accessory. So it can't be used for debugging (I know Android device in USB accessory mode shows two endpoints, one for accessory and the other for ADB, but it will be very complex to manage this USB ADB by the accessory I'm designing).
So I tried to establish an ADB connection over TCP/IP. After some issues with my network devices, I think it works now: I can set breakpoints, step into, and so on.

The problem raises when I plug the Android device to the USB accessory. Exactly in this moment, the ADB connection over TCP/IP to the device seems stopping immediately. After that, I can re-establish another ADB connection (with "adb connect" command), but it is very annoying. Everytime I restart the USB accessory software, it enumerates the Android device and put it in accessory mode, so the ADB over TCP/IP stops.

Maybe this happens because adbd running in the device listens to USB port, even if it was configured to listen to TCP/IP port. Is there a way to definitevely stop the USB listening of adbd?

Maybe is there another solution?

My app crashes immediately when the USB accessory is plugged. I can't debug what happens, because at the same moment the ADB connection over TCP/IP is lost and must be established again manually.

How do I disconnect a VPN?
I am using VPN Dragon and Hotspot Shield VPN. When it asks me to trust the vpn, I check the box and connect it, and it works fine. However, there is a problem which keeps bothering me: sometimes the connected vpn dialog stops showing bytes sent and received (Attached screenshot link) and the vpn stops working at that point. I can not even disconnect it using the button in the dialog. The only way to disconnect it is, reboot. I am tired of rebooting.</p>

How can I change background for incoming calls on my Huawei P9?
I've just switched from Galaxy S4 to Huawei P9.

The most annoying thing I've noticed so far is the background color of incoming calls.

At work I have the phone in silent mode. When the phone is inactive, the screen is black (naturally). When I get an incoming call, the background is still black and the information on the screen is minimalistic.

It's therefore very hard to notice the incoming call when my focus is on my computer screen.

Is there any way of changing this without hacking the Android OS?

adb version says 1.0.32 but droid-explorer says its 1.0.29 and won't start
Using win7 64bit.

I downloaded just the commandline tools from developer.android.com; the zip not the installer.

I copied everything to c:\dev\android\sdk\ and ran the SDK Manager and updated everything. When I run> adb version it reports a version of 1.0.32

I installed the most recent droid-explorer, using DroidExplorer.0.9.0.4.x64.Setup.zip .. during the installation it asks me to specify the android sdk directory, which it detects correctly as c:\dev\android\sdk\

After installation, I run droid-explorer wherein it states adb version is 1.0.29, minimum supported version is 1.0.31 .. I cannot launch it properly.

I added c:\dev\android\sdk\platform-tools to the Environment Variable PATH but this did nothing.

Any insight in to why the adb version is being incorrectly reported would be appreciated. I tried copying 1.0.31 binaries overtop as well and this did not solve anything.

"Fingerprint hardware not available" after TWRP restore
A couple months ago I had to get a replacement for my Nexus 6P, so I did a full TWRP backup, copied it onto the new phone, and did a restore (note that I had to rename the backup folder so that TWRP would recognize it). Since then various things haven't quite been working correctly, but one of the most annoying things is the fingerprint reader.

Whenever I turn on the screen, a red message appears at the bottom of the lock screen that says "Fingerprint hardware not available". In addition, when I go to Settings > Lock screen > Fingerprint, the fingerprints I had set up are listed (and I can rename them), but when I try to delete one, nothing happens. Additionally, when I tap "Add fingerprint", it goes to the screen to set up a new fingerprint but then a message immediately pops up that says "Fingerprint enrollment didn't work. Try again or use a different finger." Also, when I open the fingerprint screen (even while it's still prompting me for my PIN), I get this:

```<code>05-28 21:33:20.343  3787  3787 V fingerprintd: authenticate(sid=0, gid=0)
05-28 21:33:20.352  3787  6214 E fpc_tac : fpc_tac_send_get_uint32_cmd failed with retval: -3
05-28 21:33:20.352  3787  6214 E fpc_fingerprint_hal: do_identify failed -5
05-28 21:33:20.352  3787  6214 D fingerprintd: onError(1)
</code>```

repeated endlessly in adb logcat.

Deleting a fingerprint results (AFAICT) in this:

```<code>05-28 21:37:15.506 22939 22939 V FingerprintSettings: Removing fpId=983097043

05-28 21:37:15.529  3787  6214 D fingerprintd: onError(1)
</code>```

and from there it repeats endlessly again.

There's nothing else in adb logcat when I tap "Add fingerprint" besides a log entry about the Activity being started.

Any ideas? I've searched the web extensively and even poked around in the source, all with no luck.

I'm on CyanogenMod 13.0-20160522-NIGHTLY-angler, but this is definitely unrelated to the fact that it's a nightly.

App doesn't recognize moved OBB file to SD even though 'Obb on SD' Xposed module is installed
I'm trying to move the OBB files of some of my games to my SD card to free some internal storage space.

I looked for solutions and found the Obb on SD Xposed module, which says that "just enable module, reboot and move obb's to SD card (to same folder: Android/obb) - that's that." My device is already rooted and has the Xposed Framework installed. So I just downloaded and enabled the module and rebooted.

I'm looking to move Plants vs Zombies 2's OBB file which is around 600 MB, to the SD card. I've updated the game in Google Play Store and then started it to verify that it is fully updated and doesn't need to download anything.

I then moved the com.ea.game.pvz2_row directory (which contains the OBB file) in /storage/sdcard0/Android/obb/ to /storage/sdcard1/Android/obb/ using Amaze File Manager in root explorer mode. I rebooted the device and then I ran Plants vs Zombies 2 but upon starting, it started downloading resources of around ~600 MB (which is probably the directory I moved).

How do I make Plants vs Zombies 2 recognize the moved OBB file in the SD card?

Details:

Device: Lenovo A3300-HV

Android version: KitKat 4.4.2

The device is rooted. SU management app is SuperSU.

I already did the 'KitKat SD Card' fix and I have other apps that write to the SD card without any issues.

The /storage/sdcard0/ directory despite its name, is actually internal storage. This device has only one physical SD card and it is at /storage/sdcard1/.

Obb on SD details:

'Data On SD' is unchecked

Play Store Hooks is unchecked (I also
tried checking but it doesn't seem to affect the issue)

Detect SD on
Android 5/6 is grayed-out and can't be toggled (says 'No path found')

Internal Path says "Detected: /storage/emulated/0".

Nandroid Backup Fails with extractTarFork() error
Long story short, I tried to install MultiROM on my Nexus 6P, and it failed.  So I tried to restore my backup using TWRP 3.0.2.0, and it keeps failing at exactly 7800MB with the error E:extractTarFork() process ended with ERROR=255.  I have seen posts talking about checking the log when this happens, but I'm not sure exactly how to do that.

What exactly do I need to do to restore my backup?

I guess I should add some detail.  I first tried booting to recovery and restoring the backup.  The phone rebooted into a boot loop part of the way through the restore process every time I tried that.  Then, I tried flashing the phone completely back to the stock image, and then restoring.  I got the error 255 above.  Then, I tried flashing back to stock completely, wiping Dalvik/cache, and restoring the backup.  I still get the same error message.  I tried restoring everything except userdata, and the phone reboots part of the way through the restore.

I could easily reroot, reinstall Xposed, and reflash TWRP if for some reason my system backup partition is corrupted.  However, I don't want to lose my data partition at all.  That was the whole reason I made the backup in the first place.

Charging Behaviour Changed After Using Car Charger
On a recent road trip, I used a car charger to re-charge the battery on my Nexus 5 phone. Ever since, I have noticed a significant increase in the time required to charge the battery, even when using my normal charging cable. Whereas before I could completely recharge the battery in 2-3 hours, now it is taking more like 6-8 hours. My first thought was that the car charger damaged the battery in some way, but that does not seem to be the case. I have not seen any change in the battery life, just this annoying increase in charge time.

What I'm wondering now is, could the phone be 'stuck' in the slower charging mode used when charging from usb (like a car charger)? If so is there a setting somewhere I can change to get it back to normal? Is there another possible explanation for the sudden change in charge time?

Mi4i full partition corrupted. Unable to restore EFS partition
I have a Mi4i which was rooted and Cyanogen was installed. Suddenly after reboot, the phone stopped booting into the Cyanogen OS.

I tried to flash the Cyanogen again but it did not boot. I flashed the stock ROM, which is MIUI 6 and the phone booted this time. Now I could see that the SIM card was not getting detected. And also IMEI number was showing as invalid.

I then deleted all the partitions and tried to recover the phone by flashing using "MiFlash". This time too the Cyanogen OS didn't boot up. Then I again flashed the stock ROM and this time also MIUI booted up correctly. Still the IMEI was showing as invalid. I don't have any backup of the EFS partition.

I checked the stock ROM flash_all.sh script and could not find any efs partition being written (modemst1, modemst2, fsg). Then from somewhere I got the modemst1, modemst2 and nv_data partition data and I wrote the partitions manually. After writing the EFS partitions Cyanogen booted correctly. But this time the IMEI showed as "012345678901234" and "012345678901235".

As this is a dummy IMEI, the SIM was not getting registered in the network. Tried with QPST RF NV manager tool to write the IMEI which successfully did but with *#06# it still showed Invalid IMEI. Tried with a couple of IMEI flasher and none of them worked.

Also tried to write the IMEI number using AT command (AT+EMGR=1,7,"IMEI1") but the AT command was returning "ERROR"

Please help me to recover my phone. Now I have my phone with MIUI 7 installed and it is working fine except the IMEI issue.

Thanks in advance.

Does Android Marshmellow hotspot block apps?
I am trying to trace a problem with Teamviewer and I think the issue somewhere revolves around my smartphone.

I use Teamviewer 11, on a Windows 10 Tablet, using a Samsung Note 4 Mobile Hotspot on Vodafone UK.

Until last week on my Note 4 was Android 5.0.1 - everything worked as I would expect; I would load up Teamviewer, log in with my password and would be able to access my remote computers. I was then prompted for the 6.0.1 update (build MMB29M.N910FXXU1DPE1) and now I can not get a connection to Teamviewer servers.

Now, Teamviewer reports that the issue is with F-Secure (my AV/anti-spam), however with alternative connections under the same F-Secure conditions it works fine. So....

What I have tried:

Connecting using a mobile hotspot on a BlackBerry Z10 (with the same Sim Card) - Works

Connecting using my home wifi - Works

Connecting using my Note 4, with firewall or AV disabled - Doesn't work

I have checked that my Note 4 hotspot is set as a private connection, the same as my other connections and there are no obvious differences.

Am I missing something in Android Marshmellow or does it do something differently?

How do I get the CID from my HTC Flyer when it does not boot anymore?
My flyer does not boot anymore (due to unsuccessful Honeycomb update try) and I want to reset it to Gingerbread using RUU_Flyer_HTC_WWE_2.23.405.3_R_Radio_20.3504.30.089BU_3809.07.04.06_M_release_204108_signed.exe. But just executing the RUU installer does not work. I need a Goldcard. To make the Goldcard I need the CID of my device.

Usually you extract the CID by this method:

http://android.modaco.com/topic/305672-creating-a-goldcard/

Unfortunately the command gives me the following output:

C:\Program Files (x86)\Android\android-sdk\tools>adb shell cat /sys/class/mmc_host/mmc1/mmc1:*/cid error: device not found

My HTC Flyer is connected via USB. HTC Sync is currently not installed. It is RELOCKED and S-OFF.

What can I do?

"keep screen on if USB debugging" application?

Possible Duplicate:

  Disable Display Standby when in Developer Mode missing in Android 2.3

CyanogenMod has this "keep screen on if USB debugging" as a feature in Settings > Applications > Development, but my phone isn't supported by CyanogenMod and so this little life saver is missing.

I searched the Market and all I could find is Screen On which only attaches to an application, not USB debugging.

Is there a simple, tiny app that does only "keep screen on if USB debugging"?


问:
Removing charging animation from the tablet installed in a car
I've bought a no-brand tablet based on Allwinner A33 CPU running Android 4.4.2 to be put as a media system in a car. This tablet has few specific features which makes it suitable for the task but the most important one is "Quick boot" mode which keeps tablet running while powered off and then booting it in a matter of seconds (4-5 seconds) so I don't have to wait for the whole system to boot (something similar to hibernation).

I'd also like to mention that I have a lot of knowledge working with the hardware and software but my question is purely software-related.

Since I want to keep tablet charged at all times (to power RTC and to enable quick boot feature) via 5V DC in plug, when I turn off the tablet normally or via quick boot it displays the charging animation.

What I have noticed is that there are two different animations:

When tablet is powered down normally it displays animation from the boot partition and it seems it's handled by the charger application which is also found in the same partition

When tablet is powered down via quick boot it displays similar animation but I'm unable to find where this is called from.

At first I thought it fetches animation images from the bootloader partition but when I remove those images animation is still playing. Then when browsing through the U-Boot code I've seen it also handles charging animation but I've recompiled and updated the U-boot but animation is still playing.

I've also noticed when tablet is turned off via quick boot option, it keeps Android system running because dmesg gets filled with messages from the healthd application regarding the status of the battery without interrupting even when the tablet is turned off.

Ideally, I'd like to completely avoid powering on screen while tablet is turned off (car is turned off) but I'm running out of options and thought to look for a help here.

Anyone has any idea regarding this matter?


问:
need further info on how to recover a bricked Asus Transformer Pad TF300T
I've got the exact same problem as the fellow over at https://android.stackexchange.com/a/126418/170164

I'm not a programmer or developer by any means - only came across this site searching for an answer to the problem - but I'm pretty good at poking around & following instructions, and ultimately problem solving.

So I don't quite get some of the instructions in the answer provided.

Yes, I've got adb.  And I got the right drivers.  And I edited the Windows path so I can more easily use adb.

So here's the original answer:
If you can make your device appear in a PC, in recovery (teamwin) then just move the above file to a folder on the Transformer's SD card. Then on your device, pick "install update from sd" and find that file. Tap it, then wait. If it succeeds, you WILL be on CM 10.2 (Android 4.3) now, but its better than the alternative.

adb devices command does show my device in recovery

So, if I understand, I use the adb push command to move the file (which I saved in my downloads).  So, is this right?
adb push c:\locationofthefile\filename.zip /sdcard/filename.zip
(assuming lower/upper case doesn't matter?)

I got that far.  cmd is waiting on my next command.  I don't know how to access the device (since being able to access it, is, after all, what I'm trying to do here) in order to install the file from the sd card.  I assume it's something I have to do with adb, but haven't a clue where to start.

So, how do I follow the rest of the answer: "pick "install update from sd" and find that file. Tap it, then wait."  ???  Please help!

Nexus 5 volume-down button stuck, cannot boot non-safe mode
I got a bit of liquid onto my phone, and now the volume-down button on my Nexus 5 doesn't seem to work.  The button itself doesn't bother me much, but every time I reboot the phone, it goes into recovery mode, and it appears that it can only be booted into safe mode.

What can I do to stop it from always booting into safe mode?

Thanks.


问:
How to rename an ext. SDCARD
When running the stock Samsung firmware on my Galaxy Note 4 (N910C), the external SDCARD was mounted at /storage/extSdCard.
I have recently installed CM13 (Bliss-ROM) and the external SDCARD got mounted at /storage/3937-3663 instead.

As a result, my restored apps (via TitaniumBackup) are looking at /storage/extSdCard for files that are actually at /storage/3937-3663.

What's the ideal way to resolve my "apps looking in the wrong place" problem?
Renaming "3937-3663" to "extSdCard" is not possible.
Telling the apps the correct path would be very time-consuming, esp. for apps like "Tasker", which has many wrong path-entries now due to above change of path.

Any suggestions?

问:
How do I enable the Android 6 System UI Tuner?
I read here that there are some hidden settings in addition to the Developer Options on Android 6. These are also mentioned in various reviews and referred to on this site also. Apparently they can be accessed after doing certain gestures to make the cog in the quick settings menu spin.

Unfortunately it does not spin for me (and others), even if not disabling animations in developer settings as has been suggested.

Does anybody know any other secrets about how to enable that menu?

Can I return to Tap & Go when the step has previously been bypassed?
I have a new moto maxx 2, and when I first started it, one of the setup prompts was to use Tap & Go. That was successfully initiated, but did not complete because the old phone turned off. I want to go back and complete the process, but can't find any way to go back to that screen. It's not even in the setup wizard. Thoughts? </p>
