Reason Why Android Process gets killed when Task Manager is showing

Question

My Xamarin app gets killed by Android when the Task Manager shows 3 or so apps (including my app)

I'm wondering how i can find out "Why" Android is killing my App ? and none of the other apps.

i found WIN DEATH error in Android? and it could be because of an ANR, but then is there a way to find out ,what my application is so busy with on the main thread (without being able to use the Xamarin profiler..we only have VS professional , not VS enterprise)

Any help is appreciated.

thanks, tom

The Device Log shows (reverse chronological order) : (the app is called toms_app_tablet)

I see your `FloatingMeterService` is being restarted and then killed, and `MainActivityView`, `SoftMeterView` are also being killed off. So the question I would start with: what, if anything, are you processing in the service, CPU intensive? stuck in a loop? does your service try to update the activities in the background, do you hold references from your service to maybe a singleton that is ref'd to your activities causing a rapid cyclic fault path in your app, etc... — SushiHangover, Apr 06 '17 at 03:23
If your app is not really sucking up CPU in the background (remember **EVERYTHING** runs on the main looper thread unless you spin up a task/thread/runnable), I would *assume* you *might* have a memory leak and the OS is killing your app to maintain a min. free memory level.... — SushiHangover, Apr 06 '17 at 03:24
thank you for thinking along. So the service gets restarted and killed first ? the FloatingMeterService is only there because we wanted a floating window over the top of everything. There is hardly any processing done in there.. but i'll see if i can check if there is any lock or so.. i checked the _JavaRuntime.MaxMemory() : 537 Meg _JavaRuntime.TotalMemory() - _JavaRuntime.FreeMemory() : 26 Meg ...and it hardly moves.. — clogwog, Apr 06 '17 at 04:52
The funny thing is that it only happens during when the Task Manager is visible with all the other windows.. — clogwog, Apr 06 '17 at 05:02
Could just be the OS doing a low memory sweep. Also you can log memory overrides to logcat, such as `OnTrimMemory` and `OnLowMemory` — SushiHangover, Apr 06 '17 at 05:07
added the IComponentCallbacks2 handler to all of the Activities, and besides OnTrimMemory (TrimMemory.UIHidden ) none of them get called. None of them get called before the killing of the app either.. This is a hard one to nail down. — clogwog, Apr 06 '17 at 06:00
found a machine that has Visual Studio Enterprise so i can run the Xamarin profiler. Seeing that the OS is not telling me why the app is being killed, how would i go abouts identifying what is causing it ? If i run the profiler with all instrumentation Xamarin Profiler crashes right after the application crashes. I can select individual Allocations,Cycles, Memory, Performance or Time profiler.. Have gone through all of these, but can't see any threads particularly busy just before the OS kills it.. Any tips on how to identify the problem from here ? — clogwog, Apr 06 '17 at 23:33

Ok, found a solution. The App wasn't using a lot of processor time/memory or even received a IComponentCallbacks2
Used the Xamarin Profiler and it also didn't show any overuse/issue.

I noticed that the App/Service only got killed when it was 3rd in line (in the android Task Manager) or further on this particular tablet.

Added the StartForeground call inside the OnCreate of the service and i haven't seen the issue since.

If anyone knows why a service still gets cleaned up by Android (even if it is not misbehaving) i would like to know...

Reason Why Android Process gets killed when Task Manager is showing
