What is the device doing exactly when I'm pushing the (hardware) power button? I guess that's the most friendly way. You get to see a dialog with an option to power off the device (stock Android doesn't offer reboot). It appears that ShutdownActivity is called upon when you long press Power button. Anyhow, this is what you can try, remotely or locally, but ...

Adobe decided to stop support for its Flash Player on Android mainly because of HTML5 doesn't need flash player to play videos. Unfortunately, that didn't mean all Web sites you visit would start using HTML5 instead of Flash (though it would have been nice). If some of the Web sites you want to look at are using Flash, the last version of Adobe Flash Player ...

Simple, really: Android is safely shutting down vital parts of the runtime. The OS is also broadcasting intents to tell apps and services to gracefully close. These, in turn, flush their caches of all data and shared preferences, save what-nots to the sqlite database, et cetera. In other words, apps and services are given a chance to do their cleanup ...

If I am allowed to suggest out of the choices that you had provided, I will suggest Link2SD. With Link2SD you can try moving/linking a non-critical application to the SD card and check how well it works. Once moved or linked, try to reboot the phone (no other way than rebooting to avoid disappointments) and see whether that moved/linked non-critical app ...

killall zygote This will kill the root zygote process and cause a Android system refresh. This does not restart your phone's hardware, only the Android processes. By default (in Linux), the kill/killall commands do give the processes a graceful way to shut down, though it depends on the zygote implementation whether this in turn gracefully shuts down your ...

I have the same problem. It get stuck at 100% and doesn't give any notifications. Nexus 6p running Android 7.0 (not rooted). After the app reaches 100% I close the play store (swipe it away from recent apps) and start it again, it'll install and download the next app and get stuck at 100% of the next app. I am repeating the process to download the updates ...

From Android 5 onwards, there's a setting in the Developer options called Aggressive WiFi to mobile handover. Enabling this setting makes your phone switch to mobile connection when the WiFi signal is too weak. You can also take a look at a tutorial with screenshots.

The first thing to remember is that when an app runs, it doesn't actually do computation for the whole time it's running: most of the time it's idle, waiting for data to arrive over the network, or while you're looking at it on the screen. Only very badly-written apps and games keep the CPU active the whole time they're running: this runs the battery down ...

As geff described, you cannot avoid a wipe/factory-reset. But you can do a proper backup beforehand, so you can restore most of your data afterwards. This should work without any trouble for the apps you've installed yourself ("user apps"), while special care must be taken for pre-installed apps ("system apps"): As data structures (inside their databases) ...

For the following procedure you'll need adb installed on your computer (if you're not already have that, see: Is there a minimal installation of ADB?). Alternatively, a terminal emulator app should do as well. Android apps are managed by the "Package manager", which has a command-line interface called pm. So here's what you can do with it for your case: # ...

Converted from my comment on the question itself: According to a post on StackOverflow, this is most likely a network issue. In his answer there, Vignesh writes: Its due to wifi restriction, when i connect the internet through my service provider its working fine. Able to install any application.

Finally found the answer. I had four Google accounts - one of them could not sync because it required domain policy to be enforced, and I hadn't allowed that. I connected the tablet to my laptop and used adb logcat to see what was being logged when the error was displayed: I/GLSUser (28125): GLS error: DeviceManagementRequiredOrSyncDisabled <<...

Rather than sleeping, I spent a few more hours experimenting. I found what works best for my needs is an FTP server app. For casual transfers, when both devices are connected to the same network, I'll just transfer through my Access Point. With the limitations that implies. If I'm not near an AP or just want full speed, I'll deal with the hassle of ...

Turn off 3G when I've got WIFI on. I only need the mobile networks for phone calls when I've got wifi so I would prefer not to have 3G on. 3G and mobile data are two separate things. When wifi is enabled, mobile data no longer goes through the cellular connection, but it does remain connected to the 3G network (otherwise it couldn't receive calls or SMS/MMS)...

That symbol isn't Android-specific: it's the symbol for a hearing aid induction loop. Some landline telephones have an induction loop that transmits the phone audio directly to the hearing aid, so that hearing aid users can hear the phone call better than they would otherwise. The T stands for "telephone": because the induction loop system originated on ...

I just had the same problem tonight. All of a sudden my pc wouldn't recognize my S3 when I connected via the USB. I tried the USB debugging first and restarting...didn't work. I popped the battery out and restarted, and the USB icon showed up. Hope that helps. Thanks for all the helpful troubleshooting ;)

You are suffering the same problem I was after upgrading. Look in the direction of either Google Now or Google Maps. Good chance you have 'Report from this device' set in Maps Location Settings. This is murder on your battery! I disabled it and am now back at about 2% - 3% per hour on 3g with light use throughout the day. I also disabled Google Now for good ...

Disabling a notification for particular app wont' save battery. Yes it would a little by not ringing and vibrating and also by not making you look at the phone. Actually notification is handled by OS itself. An app just says that I want this notification to be displayed and OS handles it. In your case those apps are running in background using service and ...

Rendering Tamil characters is a challenge as there is no one glyph to one character mapping as in English. Earlier versions of Android (before 4.1) does not have this support natively. Which means unless the manufacturer or the author of the ROM decides to additional support, Tamil characters cannot be rendered properly. There were few hacks which helped ...

You can specify quite a bit of logic in just the contexts. Having a profile with multiple contexts would be the easiest way to accomplish this. Remember that all contexts have to be met sequentially before the task(s) will fire. Also, the Wifi Connected context will accept multiple SSIDs by using pattern matching. In this case a / equals logical OR. Try the ...

I'm digging up this question since I found it looking for the same problem. Putting single quotes around the parameters solved it for me: adb backup '-all -apk -shared -f mymobile.ab'

It just works, no need to wipe. You don't need to wipe, according to a blog post on CyanogenMod's Google Plus channel: Upgrading from CM10 to CM10.1 As you may have noticed, we started updating some devices from cm10 (Android 4.1) to 10.1 (Android 4.2) during the weekend. The upgrade process has been tested extensively for the older devices (manta ...

Go to Settings > About phone > Model number, and see which one matches: Samsung Galaxy Nexus (Maguro; GSM/HSPA+) - GT-I9250 Samsung Galaxy Nexus (Toro; Verizon; CDMA/LTE) - SGH-I515 Samsung Galaxy Nexus (Toro Plus; Sprint; CDMA/LTE) - SPH-L700 Edit #1: You can also check the back casing if it has Verizon (toro) or Sprint (toroplus) written on it. ...

It's not that Jelly Bean won't support Flash. Adobe decided not to support Flash for newer devices, starting from Jelly Bean and onwards. I don't know the know the reason though. Maybe they got tired of testing (and certifying) several devices? Source. You can still install Flash on Jelly Bean; there are workarounds for that.

You can do so by having your WiFi switched off when its signal gets weak. There are several apps available on the Playstore which can watch the WiFi signal, one of them being Tasker (which is what I use). Here you can define a minimum level and tell Tasker: If WiFi signal falls below this, switch WiFi off. Of course you can make it even more detailed, and ...

Instant Upload is a feature of Google+, which uploads the photos you take with your camera to a private photo folder on Google+ for easy sharing. This option allows you to enable/disable this feature, but it can also be controlled from other Google apps like Google+ and Google Settings.

In Linux/Android it is not recommended to close apps or use task killers. Unlike a Windows computer/phone, Linux/Android can keep applications "running" in the background which doesn't use any CPU or networking (unless it's a media player). It has actually been proven that closing apps causes more battery drain, because instead of Android being ...

I'm Budius, the developer of the WiFi Shoot! and I must say that J4velin's explanation is really spot on and pretty sad. I started developing it just because I saw this cool technology and no one was using it but it only proved to be a big headache. Even during development (I was using a Transformer TF300 and a Galaxy Nexus) it took me much more time than ...

There are several possibilities: manually setting all volumes to 0, except for those channels you want to keep (e.g. alerts, notifications, system). Issue: on some devices/systems some channels seem to be "locked together", so as soon as e.g. volume for calls is increased, some other slider increases automatically along. An app like Audio Control might help ...
