You can catch all uncaught exceptions in your Application extension class. In the exception handler do something about exception and try to set up AlarmManager to restart your app. Here is example how I do it in my app, but I only log exception to a db.

public class MyApplication extends Application {     // uncaught exception handler variable     private UncaughtExceptionHandler defaultUEH;      // handler listener     private Thread.UncaughtExceptionHandler _unCaughtExceptionHandler =         new Thread.UncaughtExceptionHandler() {             @Override             public void uncaughtException(Thread thread, Throwable ex) {                  // here I do logging of exception to a db                 PendingIntent myActivity = PendingIntent.getActivity(getContext(),                     192837, new Intent(getContext(), MyActivity.class),                     PendingIntent.FLAG_ONE_SHOT);                  AlarmManager alarmManager;                 alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);                 alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP,                      15000, myActivity );                 System.exit(2);                  // re-throw critical exception further to the os (important)                 defaultUEH.uncaughtException(thread, ex);             }         };      public MyApplication() {         defaultUEH = Thread.getDefaultUncaughtExceptionHandler();          // setup handler for uncaught exception          Thread.setDefaultUncaughtExceptionHandler(_unCaughtExceptionHandler);     } }
