Is onDestroy called in an application when the phone runs out of battery?
android,shutdown,ondestroy,application-shutdown,system-shutdown
In reality there is no telling what will happen. There's even doubt about if onDestroy() will be called under normal circumstances. One of the few situations where onDestroy() in an Activity SHOULD be called is when using the BACK button or if an event in the Activity explicitly results in...
More than one principal activity
android,android-activity,root,oncreate,ondestroy
When you call your activity, you can try to take the running one and put it in the front with : intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); I recommend you to check your Manifest if there is something like : android:launchMode=["multiple" | "singleTop" ] It is also possible that your device run out of memory...

Android - destroying service on calling stopService
From the docs: Once requested to stop with stopSelf() or stopService(), the system destroys the service as soon as possible. However, if your service handles multiple requests to onStartCommand() concurrently, then you shouldn't stop the service when you're done processing a start request, because you might have since received a...
Scope not being removed
angularjs,controller,angularjs-scope,ondestroy
The short answer is, $destroy is not automatically called by Angular when an element is removed. You must call it explicitly (https://docs.angularjs.org/api/ng/type/$rootScope.Scope): $destroy() must be called on a scope when it is desired for the scope and its child scopes to be permanently detached from the parent and thus stop...
Android initializatoin of class fields not done
java,android,initialization,ondestroy
Statics are statics -- they are global to the process. So their value will last for the lifetime of the process, which is usually much longer than an individual activity instance. Source: https://groups.google.com/forum/#!topic/android-developers/PZXbCXliRbo...
Android onStop onDestroy called after onCreate

Can we have blocking waits in onDestroy()?
The onDestroy method (as well as all other activity lifecycle methods, view callback methods, etc.) is called on the application's main UI thread, so no, you shouldn't block for a significant period of time when called. Doing so will likely result in lag, and may even spawn an ANR (application...
Android Alarm not triggered after finishing
Regarding the leak warning, you can define your receiver in your manifest like so <receiver android:enabled=["true" | "false"] android:exported=["true" | "false"] android:icon="drawable resource" android:label="string resource" android:name="string" android:permission="string" android:process="string" > . . . </receiver> this will give you the expected behavior. Reference here. An example: <receiver android:name="MyReceiver" > <intent-filter> <action android:name="com.doopy.numbers.ACTION_PLAYREMINDER_DAILY"...
Registering “onDestroy event handler” with Android Activity
android,android-activity,ondestroy,eventhandler
You can make your library class implement Application.ActivityLifecycleCallbacks and then register it using getApplication().registerActivityLifecycleCallbacks(libraryClass); Then your library class will receive all activity lifecycle callbacks from your application. If you're only looking for one activity's lifecycle events, the ActivityLifeCycleCallbacks methods have Activity parameters and you can filter for the activity you're...
