Android Jelly Bean - Download and install Download Manager without a pc
I'm writing this from the tablet having the issue.

2 months ago when I still had a working pc I wanted to install Linux on my tablet and in the process I wiped mostly everything from it and changed the custom recovery to not include those wiped app files.

I wanted to put Android back, but I forgot to download and install the missing app files for it to work correctly, the most important being the Download Manager.

Today my pc unfortunately broke up and I have a project to be done. So I thought to begin using this tablet to program as I have no money to buy another pc for maybe a year.

The problem is that I can't download anything as I'm missing the Download Manager app. When I try to download something for ex. with Chrome it crashes.

Now, given that I have no access to a pc for a year or so but my tablet is fully rooted, is there a way to download and install the Download Manager apk?

My thoughts on possible theoretical ways:

As I can't download but copy/paste text from the net, I could try to look for the Download Manager apk, copy its source, paste it on text file and give it the .apk extension.

Trick the Chrome cache to store the .apk file and then retrieve it from the cache offline. But here I don't know where the Chrome cache is stored and I'm afraid it's in a privileged part of the system where only a file manager with root functionality can see it.
2.

If it's supported create a script on Jsfiddle to fetch the apk file and save it through IndexedDB or LocalStorage and access it offline thereby being able to install it.

My question here is: Would that work? Otherwise have you ideas on how to do that given the current situation?

Cant find the delete dumpstate/logcat on my Galaxy TXT (Y Pro, B5510)
My internal storage keeps running low, even though I keep removing apps, and I only have a handful of apps installed. I cant install updates anymore either for the ones I do have because of this. I read somewhere that i could try deleting the dumpstate/logcats by dialing *#9900# using the 2nd option: Delete dumpstate/logcat, but after dialing that number, this option is not showing up anywhere on the Sysdump list of my phone. Is there some other way to use this option?</p>

Secure boot while still being able to keep up with nightlies
Following this great answer, I've secured the bootloader on my Nexus 7 deb by using fastboot oem lock and installing the original Google-provided recovery image.

However, I now have a dilemma. Here's my setup:

My device is encrypted with a very strong passphrase.

I'm running a CyanogenMod nightly, but I'm planning on sticking to more stable releases as they become available. (The nightly which I'm running is because it provides keyboard layouts as imported from AOSP that were previously unavailable)

Every so often, I'll get a crash and the device will reboot itself, there are weirdness with Bluetooth, etc. This I have accepted with running nightlies, I know what I'm getting myself into.

I just realized the terrifying truth: in order for me to fastboot oem unlock my device, a user data wipe is necessary. That really, really stinks.

Is there a way for me to do this without wiping my data? Moving forward, is there a way for me to both maintain security of my device and be able to flash new updates to my ROM?

问:
Convert Tablet into idiot-proof PC monitor
I'm working on a new classroom space at a small college. The goal is to have a fully wireless lecturn for the instructor. That includes power cables: everything must be battery powered. This means sticking all the powered A/V equipment (especially the PC) off to the side, where it can be plugged in, and only including what is effectively a terminal on the podium.

What does that have to do with Android? I'm glad you asked. I still need a display for the lecturn. I need a small-ish screen that can run on a battery for several hours at a time that I can connect over wireless to a PC. I'd prefer a dedicated monitor product, but since I can't find that anywhere, an Android tablet sounds perfect.

So here's the question: how can I set up an android tablet to do this?

I know there are a number of apps out there that support this at a basic level, but just the app alone is not enough. I need the result to be really idiot-proof. If at all possible, I want people to be fooled into thinking that the tablet is nothing more than a monitor: they wake up the tablet and the PC screen comes up with no additional touches, even if no one is logged into the PC yet. This also needs to function as (in some instances) the only monitor for the PC. Kiosk support of some type would be ideal, as well.

For what it's worth, I'm also exploring using a UPS (with the alarm disabled) with a traditional display and wireless dongle, but the android solution just seems much more elegant.


问:
Why do I sometimes get requests for root access from unusual applications?
I have a Samsung Galaxy S3 running a rooted stock firmware, Occasionally I get a popup from my superuser application saying that an application that I did not specifically install or launch has requested root access. I always deny these requests, obviously, but I'm not sure why they happen in the first place.

The most recent was from "Google Backup Transport", which, being a preinstalled application, seems like it shouldn't be asking me for root. At least one other person appears to be having the same issue, but I can't seem to find much information about it. I don't remember the previous application names, as it only seems to happen every several weeks or so, but it is not the same application every time.

Could this be indicative of a malware infection? If not, why is it happening?

EDIT: It just happened again - this time it was SyncMLSvc requesting root access - it seems to be a Samsung service.

Open links in standalone dedicated application
Im not sure how to word the question exactly but I will try and describe what I mean.

If im on a website, email or any app and there is a link that can be opened in a certain app, For example, clicking a youtube link, instagram link, pintrest etc it "opens" that app. But when I hit the multitasking button to look back on the site/email/source of the link, I find that the app is actually "inside" the source. For example, even though its opened the youtube app, when you click on the multitasking button it actually shows up as chrome (im not talking about it loading the youtube website).

Can it be set so it physically opens that respective app rather than "virtualising it" inside the source app?

I know this may sound very confusing...if so let me know ill try again or maybe do a video of what I mean...

Nexus 7 (2013) won’t go past Google logo screen, can't enter Recovery mode
I hold down the power button until it starts up, and it gets up to the Google logo screen, but won’t go any further; it just freezes on that screen.
Tried to reset device in Recovery Mode (support.google.com/nexus/answer/4596836?hl=en) using these steps:

If your tablet is on, turn it off.

Press & hold the Volume Down button, then press & hold the Power button simultaneously until the tablet turns on. You'll see the word "Start" with an arrow drawn around it.

Press the Volume Down button twice to highlight Recovery mode.

Press the Power button to start Recovery mode. You'll see an image of an Android robot with a red exclamation mark and the words "No command."

While holding down the Power button, press the Volume Up button.

Use the volume buttons to scroll to "wipe data/factory reset," then press the Power button to select it.

Scroll down to "Yes - erase all user data," then press the Power button to select it.

Points #1-#3 go well, but I can't pass through #4, after pressing the Power button to start Recovery Mode there is no 'image of an Android robot with a red exclamation mark', screen just goes off for 1-3 sec and than there is again Google logo screen, performing actions from #5 gives no result, tablet just goes off if I hold the Power button and the Volume Up button too long.

How to restore Google Search withOUT Google Voice Dialer?
Stack Exchange newbie here.  Please forgive any protocol mistakes.

I'm following a thread, but can't yet comment as a newbie, on a question involving the Google Voice Dialer for Android 4.1x - everyone commenting knows that the prior version worked fine but a new OTA push made it serious junk.  I've followed some instructions that say to disable Google Search so that the system will use Voice Commands instead, and that solution works consistently well.  However, additional instructions state that one should then re-download Google Search to reinstall it. This does not appear possible... when an app is disabled, it indicates this status in the Play Store and one cannot opt to download a fresh copy.  And re-enabling Google Search just puts the crappy Google Voice Dialer back online.

What app is activating all of my apps in turn?
Something on my phone is repeatedly cycling through all (or most) applications. Several times a day, it activates an app for a couple seconds, then moves on to the next app. It will continue doing this for many apps (maybe all of them) and it will repeat apps. Eventually it stops, but it will start again later in the day.

I notice the behavior because the rest of the phone, including the dialer, crawls to a halt. If I look at Apps -> Running I see the cycling app at the top. The screenshot shows that the cycle is currently on Facebook - an app that I have literally never used on my phone. It will cycle next to YouTube, Slacker, etc.

How can I figure out what's doing this, and how do I make it stop?

I've tried the following with no effect:

Repeatedly killing all Google Play services or processes that might be checking for updates.

Ensure that some of the activated apps are fully updated. They still appear in the running apps cycling.

Disabling Google Settings -> Verify Apps

How to Repair IMEI of rooted phone without backup

Can I create a stock recovery from Nandroid backup or from OTA? How?
I am looking for a stock recovery for my phone (HTC One M7, rooted, s-on,CID: HTC__102, Software number: 4.19.401.11). But I cannot find it. The reason I want this recovery is that I want to experiment if it is possible to keep my phone rooted but going back to Stock recovery so that I can get OTA updates.

I have a nandroid back up of my stock ROM (I created it in TWRP, so it is after flashing the TWRP recovery),  and also I have downloaded an OTA for my phone from forums.

Is it possible I can get an stock recovery image from OTA zip file or Nandroid backup?

Reorganizing Android storage
My Android device (rk2928, Android 4.1.1) currently has NAND flash on sdcard and the SD card on external_sd. Moving an app to SD keeps it in flash but takes up more of it total, so I'd like to reallocate the NAND flash used for sdcard into internal memory and then have the SD card on sdcard. How can I do this? Or is there a very good reason why I should not do this?

Clock frozen in the notification bar
Every once in a while, my Asus TF300T freezes for a bit and some apps crash. I notice that when this happens, the clock freezes in the status bar. For example the time in the notification bar will be 12:25 but the Clock app will show 12:28. This issue can easily be resolved simply be restating my device, but if I am the middle of working, I do not have time to wait 10-15 minutes for it to start back up again. Everything else functions as normal, such as buttons and notifications. My device is not rooted.

In this screenshot you can see the clock says the correct time and the frozen time in the upper right corner

How can I "unfreeze" the clock in the notification bar without restarting my device?

Use data connection when WIFI has no internet access
My friend has a wireless router in his car that supports streaming music. I would like to stream music to this router from my google play (or other internet source), but as soon as I connect to his router, I lose internet access (since his router doesn't have any kind of outside line). It seems that even though the router clearly doesn't have internet access, android is shutting down my 4G connection. Is there any way to change this behavior, or is it expected to change in Android L? It is a little disappointing that this doesn't work as it seems the iPhone has supported this for quite some time.

问:
Why does my Android have an 8MB hosts file blocking thousands of sites?
Background: my Android is the only source of internet I have - I use it as a hotspot while at home.

I have been noticing strange behavior out of my Desktop PC recently: sites like Amazon were not styled, and Yelp.com wouldn't work at all (as if it didn't exist)! Then, I attempted to use Yelp while I had WAMP running on my PC, and it redirected to my local website.

I soon discovered it was not a hosts file on my PC causing the issue, but the host file of my Android device from which my internet was coming.

I grabbed a terminal emulator from the Play Store and cat'd my hosts file into a text file, then retrieved it from my phone. It was 8.12MB, and it blocks 283,000 websites by redirecting their names to 127.0.0.1.

What is this madness? Most of these sites appear to be spam or inappropriate, but why are they blocked in this manner? Does Google do this? Why is Yelp.com blocked!? And why are Amazon's CDN servers blocked, too?

For now I think I'm going to manually edit the hosts file on my phone to get around this, but I would really like some answers, if anyone has any!

Thanks!


问:
Either downloading images directly to SD card or moving to SD while retaining original time stamps?
I have a Samsung Galaxy S4 with 4.4.2. When I read manga online and save the images the files in a given sequence are generally in a 1, 2, 3, 4, etc. numbered format. When I copy these files from the DOWNLOAD folder to the SD card though it ends up arranging them like 1, 10, 2, etc. regardless of the file manager I use AND it changes the time stamps at the same time so that it's permanently stuck like that. At the worst, I had over 5k images get scrambled and I am NOT looking forward to sorting them out one at a time on a desktop computer.

I would like to avoid this problem in the future. I would either like to have them save to the SD card right away, or I would like to be able to have the files retain their original time stamp when moved to the SD card so that I can retain the order of viewing regardless of the name, or both. (Renaming one at a time to 001, 002, 003, etc isn't really an option.)

Note: After the update (which AT&T forced on me without my permission), I rooted my phone with towelroot and Superuser and edited permissions to regain the ability to copy without problems, so if there is a solution that requires a root I am ready for it.

Is it possible to take slow-mo video in high resolution on Galaxy S5?

问:
Poor NFC recognition after replacing Nexus 4 back cover
After replacing the back cover on my Nexus 4, the ability to read NFC tags has decreased significantly. I replaced the back cover of my Nexus 4 with an original(!) replacement because the glass had broken. Yes, the new back cover has NFC and I've confirmed that by scanning the tags I used even before the cover replacement. It does work, because the tags can be scanned, but it takes a lot of tries and often I have to give up.

I test NFC capability by holding a known valid NFC tag at the center of the phone's back, and if that doesn't trigger then I very slowly slide the tag around the back, and repeatedly remove/reapply the tag. All my tags are the "sticker" type, and they're placed on a wooden surface (not metal), so it's not a matter of material or thickness.

I don't think I did the cover replacement badly, because it does work occasionally. Is it possible that the replacement is a poorer quality than the first? What can cause this problem, and how can I determine & fix it?

Tracking down which app makes HTTP requests
After configuring my Galaxy S4 (Android 4.4.2) phone to use a proxy server for debugging an app, I noticed that other apps on my device were making some suspicious HTTP calls.  I would like to track down what app is doing this.

Unfortunately, the request itself didn't have any clues... it only contained a generic User-Agent header:

```<code>User-Agent: Dalvik/1.6.0 (Linux; U; Android 4.4.2; SPH-L720 Build/KOT49H)

The response was also generic, and not related to anything I have knowingly installed.

问:
how can I control the second internal clock
My alarm clock app has been occasionally failing to ring in the morning, but I don't believe the problem is due to the app.

In other news I recently added a lock screen app that happens to display the time in two locations on the screen (one from app itself and other my widget) and on days when the alarm fails to ring I noticed that the second clock just stops, (which today says 3:52 am)

I have been checking the two clocks before bed, but last night when I checked it was good, yet the alarm failed this morning and now the times are different

I presume there are two internal clocks and the lock screen and alarm app are both using the problem clock, which is probably being killed by some task killer.

I can't afford to oversleep again!

There are bunch that sum up to 50 MB only (the total size is 1,13 GB) and many folders show up as "0 bytes" in usage, which is strange.

DiskUsage app shows that "system data" takes 90% of the storage, but I can't figure out what to delete or uninstall to free some space. How or what can I delete to free up space (I believe that apps themselves can't take up this much storage, I don't have that many I think).

NOTE: I moved hopefully all the apps to the SD card before.

I had peace of mind that no person can look into my personal stuff and business stuff, my credit card details etc. But, today in the morning I was surprised when Google Plus notified that a photo was uploaded from the phone. Its an old phone screenshot which I took one day before 7th July, 2014 ( The day when I returned the phone ).

So, what I want to know here is, is Google photo upload got stuck somewhere for 6 days as today is 13th July, 2014 OR some person from sony staff was able to decrypt my phone? I am a little worried about my personal stuff now. Had so many accounts linked there and now I will have to log in into each google account one by one and sign out all devices.

I have a Nook HD+ with kivy installed. When I connect the device with USB I can use Windows Explorer to see the directories and copy files to the Nook. But the log files it generates don't show up in Explorer. I've installed BusyBox so I can copy files around, and copying one of the logs to the base program directory works fine - ls -l shows that the permissions and owners are the same as the other files in the directory. But I can't see them from Windows.

I don't know which version of Android, if someone can tell me how to see it I'll add the information to the question.

What causes Android to have slow WiFi performance?
I have a Samsung Galaxy SII (GT-I9100 with Android 4.0.3) and a Samsung Galaxy Tab 10.1(GT-P7500 on Android 4.0.4). They both perform awfully slow on WiFi for internet related Apps.

Either Facebook, YouTube, Any web browser (Chrome, Mozilla, Dolphin and native) perform like if the WiFi connection was a slow one. Frequent time-outs in Play Store, videos taking forever to buffer, etc.

I Know for sure that at least at home the router/modem is not the issue, as I can have two laptops running Windows consumming WiFi at normal speeds, i.e. each one streaming a video on YouTube without pauses for buffering, but at the same time, one of my androids woul not even be capable of playing the same video, or take, say 1 minute to load a page that on my laptop loads in 2-3 seconds. The same happens in other WiFi Networks I connect them to. My devices have developed this behavior from 10-8 months ago and it has slowly worsened over time,

Is this something related to the Android Operating system? Could it be one of my apps? And if it is one of the apps, how can I identify and kill it?

It does not seem to be a disconnecting from network problem, I get steady connection indicator.

Note: I consider myself almost a lean user: I don´t keep a lot of apps and dont usually leave running the ones I use (i.e. I close the browsers, the facebook app, etc, and constantly check whether apps are running with the app manager).

Note 2: These devices sometimes work faster on 3G, wich doesn't make much sense because here in my country the provider is not very good and many of the cell towers(antenas) are clogged with a too many users. In these cases I normally get the normal, expected lag of such network.

Have a galaxy s3 rooted stock jelly bean 4.3

I've been doing some mods recently (not my own just downloaded)
I've undone the most recent ones I've done as only recently the problems started
Haven't you done a restore via CWM as don't want to completely lose the changes I've made

But text messages are sending but always showing up as sending icon (not actually sent)

Any suggestions?

Thanks

Can Android prevent you from using up the very last bit of your prepaid-service credit?
Is there a setting that warns you or prevents you from using up the very last bit of your prepaid-service credit? For example, when you are low on credit, but want to prevent yourself from using all of your credit. This way you wouldn't get into a crisis situation unable to call for help. Does such a setting or feature exist in Android?</p>

Faulty battery status indication
I have a Huawei Honor U8860 with Android ICS. I use two Mugen Power batteries. I always use one battery until it's empty, then charge it to full while using the other battery. Recently Android battery level has started to behave incorrectly. The battery level drops dramatically, then stays at the same level for a long time. I experience similar behavior with all the three batteries I own: the Mugen Power batteries and the original battery.

Below is the battery status chart at this moment. Suddenly the battery level dropped to 3 % yesterday, but it stayed there and I've been able to use the phone actively for another day since then. Clearly the battery is still performing well, but Android gets incorrect information about the charge, sometimes even shuts the phone down.

I tried calibrating with Battery Calibration app, but the problem has only got worse. Any ideas what's causing the problem? How does Android get the battery level? From the electronics integrated into the battery or by deducing from the voltage level? What does the calibration actually do?

Unexplicable battery draining on Galaxy Nexus
Okay, so first some details:

Samsung Galaxy Nexus (GSM version)

Stock rom (rooted)

Brand new stock battery (1750mah)

I started suffering from unexplainable battery draining a few months ago. And with that I mean draining from fully charged to empty in less than 10 hours with almost no usage at all.

I must add that I frequently flashed custom roms on there, particularly unofficial 4.4 roms for maguro (galaxy nexus). As a last resort, I installed the original and last release of JB on it again, for me 4.3 yakju.

Since that also did not fix the problem I bought a new stock battery on ebay. I thought that obviously the battery must be broken, since it would also drain battery even when powered off. Except the fact that the battery drains less slowly, the battery is also draining spectacularly (it now drains in 12-13 hours approximately)

As a final note: I am now running stock 4.3, with virtually no apps installed. Syncing is off, no wifi, no 3G no nothing. Even with my old battery, it would last a day with moderate usage.

So my question is whether you guys have any ideas or leads of what might have happened? Did I fuck up my phone by wrongly flashing it? If so, is there something that can still save my phone?

During locked screen: Notificaton 'Rights requested'. Google Account manager then crashes
Since a few days ago, my device has started showing an exclamation mark in the status bar when the lock screen is active. Today, this happened several times.

In the notification area there is a message that says:

Rights requested for account myAccountName@gmail.com

This is the phone's main account.

If I click on the message, Google account manager seemingly starts - and immediately shows a message indicating it has stopped. I assume this means that it crashed.

I didn't do anything myself that created the notification the notification since lock screen was enabled.

Is this is just odd programming, Or should I investigate further? May a virus be active?

System: Galaxy S3, Android 4.3 and SRT AppGuard installed.

UPDATE 20140720

I long-pressed the notification to get App details. Reports the details of Google Account Manager.

As said in my comment, I'd expect a crash in a user-installed application.

How to detect if bootloader is unlocked when fastboot doesn't work?
I have this tablet that runs on RK3168 (Rockchip) SoC.  The problem is that fastboot doesn't recognize the device, but after so much toil, I managed to find Finless' flashing tool and flashed CM Recovery image unto the device.  The flashing worked because when I rebooted to recovery mode, it showed CM recovery screen instead of the stock recovery screen.

The flashing tool is a windows GUI.  It doesn't have an unlock bootloader function.  But since I was able to flash the recovery image successfully, my question is, does this mean that my device bootloader is already unlocked?

Edit: (more details)
Using Finless' flashing tool, I backed up all the NAND partitions and named them accordingly, e.g. backup.img, kernel.img, etc.  Then I reflashed them all back into the device but reflashed a different recovery.img.  I reflashed a generic CM that I got from this site instead: http://androtab.info/clockworkmod/rockchip/

I did all this with the assumption that the flashing tool actually works.  After all, I used it to make the backup as it was the only tool that detected the device in fastboot mode because fastboot just doesn't detect it.  (It could be that the bootloader interface driver doesn't work properly for fastboot on Win x64, but I don't have the luxury of setting up a 32-bit OS.)

When I rebooted the device, everything was fine.  Rebooted into recovery mode and CM recovery screen showed up.

I'm still new to all this android flashing stuff, I don't really know what an unlocked bootloader means, and I just read from other guides that in order to flash a custom recovery, I need an unlocked bootloader first.  So I'm presuming that if I was able to flash images, that my bootloader is already unlocked?  But I'm not sure, so that's why I'm asking (albeit a very naive question...)

ACRA init crashing after new rom flash
I recently flashed CM11 on my GS2, it was slimkat 4.4.2 earlier. I believe I did a dirty flash because all my apps and settings were present when I booted it. I used the "recommended" wipe on TWRP.

Some apps gave issues (particularly settings > developer) but wiping app data fixed that. However some apps, watchdog lite in particular is having crashes before it starts (everytime). From logcat, this looks to be due to ACRA init. Clear app data or even app reinstall doesnt fix it. Anyone have any idea?

HTC Desire X doesn't come up after software upgrade
I want to apologize in advance if this isn't the proper forum for my question; it might be a hardware problem.

I got a message on my HTC Desire X that a software upgrade was available. (IIRC I was on 4.1) I checked if there was enough juice in the battery, enabled WiFi, and downloaded the upgrade. But when I clicked "install" the display simply went black, and the device hasn't given any signs of life since.

What I tried

1. Remove and re-insert the battery

2. Recharge the battery. This shouldn't have been necessary, since it had enough power, like I said. But strangely, even after 24h of charging the power LED remains orange

3. Factory reset: volume down + power button

The battery thing bugs me. It was a good battery (normal charging times) and now it doesn't work anymore. Does the charger rely in the CPU? For instance, if the upgrade really went bad and the CPU doesn't work properly, what about charging.

IF the upgrade didn't succeed, is there a way to get the device working again?

When the phone is new or, fresh factory reset, the mobile Internet connectivity is really active. This means, messages in WhatsApp, email notifications from GMail occurs properly in time. But gradually on usage, say 2 - 3 months, these apps take more time to notify new messages when the screen is off. When the screen is ON, messages are received instantly.

Observed only in mobile Internet. (H+ or H - WCDMA auto mode).

Not observed when in Wi-Fi.

Facebook notifications are in-time and this problem is not observed by the app. Only WhatsApp and GMail tend to suffer.

What could be the problem? Any suggestions?

Google Play Store behaving strangely: apps don't install
Lately, when I try to install apps from the GPS, the following things happen:

When I tap "install," the blue "waiting" bar shows up. (I don't know whether there's a better name for it.)

Instead of turning into a progress bar that shows the app downloading, the "waiting" bar just sits there. I eventually hit "stop".

When I go to the GPS on my computer, the apps I have unsuccessfully attempted to install show as installed, even though they're not. (And they don't show as installed on my phone.)

Has anyone seen this behavior before? What is the remedy?

EDIT. The phone is a Moto X, not rooted, on a cellular connection. It started maybe a week ago. I can't think of anything I might have done to provoke it.

Can Asus Nexus 7 WiFi support a Huawei E3276 4G usb dongle SIM holder to achieve telephone functionality?
I could connect (with an usb adapter) a Huawei usb dongle that I normally use with my laptop computer and contains a SIM card for mobile internet and phone functions like SMS and phonecalls, but it doesn't seem that android (4.4.4) with my Asus Nexus 7 WiFi edition recognizes the device. Can it be done, or should I investigate other ways to enable mobile internet and telephony for my Asus Nexus 7?

How to sync my iCloud email acct using the stock email app?
I am using cyanogenmod11 on both my phone and tablet which comes with AOSP email app. I've also tried the latest stock email app that Google released recently on the playstore.

No matter what I do, I can't get my email. The server settings (both imap and smtp) validates fine but nothing happens.

I've looked at various guides available in the net. They are very much the same. The settings used are the same.

I have tried K-9 mail app using the same settings and that works fine retrieving my data. So I believe I'm using the correct settings.

Any ideas what I could set in the stock email app?

Thanks :)

Left Alt on External Keyboard Helper for use on JuiceSSH and Finch
I like to use JuiceSSH to connect a remote machine which is running Finch.
Finch uses Alt as its hotkeys prefix, for example Alt+n to go to the next window.

I have an external Bluetooth keyboard which has a left Alt key and a right AltGr key. The AltGr key is working fine, my problem is with the left key. The only configuration I found in the Custom Keymapping is to put left Alt as left Alt modifier. But that's not what I want, I don't want left Alt to be a modifier, I want the application to receive left Alt as it is, so that I can use shortcuts like Alt + n, instead of getting the char ñ.

Basically, I want to be able to control Finch using the left Alt as the shortcut prefix.


问:
Galaxy S4 Calendar settings not saving
I prefer Google Calendar over Samsung's built in calendar app on the S4, for notifications. I don't need to remove the latter, and can't seem to; I just don't want it to display notifications. So I change the relevant settings, but periodically they revert.

I completely turn off notifications in S Calendar (no tone, no vibration), and turn them on in Google Calendar (with a specific sound and vibration and popup notification). In Google Calendar I also turn on "Show week number" and set "Week starts on" to Monday.

After some testing it seems these settings stay in place for as long as the device remains on. After turning it off and back on again, all of the settings in both S Calendar and Google Calendar, including the ones I mentioned not related to notifications, have reverted to their defaults (with notifications ON from S Calendar and OFF from Google) with the exception of the tone that I set for Google.

I'm fairly sure that having my phone turned off and then on again is exactly what happened each previous time I've noticed that my settings reverted.

I've looked at this post, and none of those solutions (for non-rooted phones) work; the settings still get reverted when I change them, and Samsung's calendar can't be turned off in Application Manager. If both calendars are having this issue I'm not even sure removing S Calendar would fix it.

A commenter on the first answer there seems to have the same issue, apparently since a recent upgrade. That may be the case for me too, because I bought this phone a year ago, but now both the device info and the app info for S Calendar have Android 4.4.

Why would these settings be reverting on every restart? How can I fix this, besides just not turning my phone off?

Modify shorcut or executable?
My car is a Chevrolet, and uses the Mylink radio system. It basically comes with some shortcuts (fixed) to run certain (limited) apps on an Android phone and show the phone's screen on the stereo car screen.

I want to run any app of the phone in the car screen.

So, my question is:

Is it possible to change the executable or shortcut on the phone to run another app?

For instance, my car can call an app called Bringgo. Can I change on the phone the shortcut or executable name to run Google maps instead Bringgo? So, If I tap the Bringgo icon on the phone, Google maps should run.

I think should be something like a symlink in Linux.

I have a rooted s3 mini, with CM 11.

Can I disable the volume warning if I raise the volume too much?
Occasionally when I raise the volume on my HTC-one, I get a warning message which stops me until I click 'Ok'. It's more of an annoyance than anything else. Can I disable it? I can't seem to find an option for it in the settings.

This question has already been asked here, but it was over a year ago.
There was no solution then, I'm wondering does anyone know if there is a solution now?

Catching a hidden application
In my Android, when I turn on the screen I see a quick flash pop-up that says: "Network error: it is impossible to connect" (or similar, I am from memory). This is logical as I have manually turn off data usage, but I would like to know which app is writting that message, in order to see if there is any setup to avoid it, or to write author. It is a bit annoyed.
Any ideas how can I know which app is it? I have lot of apps.

Thanks

Moving text messages from 2.2 to 4.2
I had recently purchased new LG Optimus L90 (model D415, Android 4.2.2, default OEM set up, Optimus UI) to replace old Optimus T (Optimus One, P509, 2.2). I had used SMS Backup+ to move my messages, call logs etc. I had successfully used it before when I did factory reset on the old mobile.

When I installed SMS Backup+ on the new phone, it did copy call logs, and it seemed to copy messages as well, because when I would tap the message icon for the first few times, it would flash old messages for a fraction of a second, but then would only display the new ones. I tried reboot the phone, and checked the settings, but nothing helped.

Is there a way to make this work, or should I try another app?

Update: I had tried restoring the messages again today, and when I check the list while SMS Backup+ is running I can see it populating with contacts that I had exchanged messages with. But if I click on any of them there are no messages inside, and so the app thinks of those as deleted and clears them upon list refresh.

Android x86 will not connect to the internet
I am using Android x86 4.4 RC2 (Dual-Boot not Virtual) and I can't connect to the internet. Whenever I click Wi-Fi, it stays on "Turning on Wi-Fi" and the Wi-Fi button is grayed out like the option is not available. I opened the terminal and used netcfg to see if the Wi-Fi driver (wlan0) was on but it wasn't so I turned it on by typing "netcfg wlan0 up" and it was up so I went back to the Wi-Fi settings but it still wasn't working. What do I do to enable Wi-Fi?</p>
