Question

I am using android.app.Application to create a single instance. For some reason I see Android kills my Instance and recreate (call onCreate). How can I stop this from happening ? I tried adding logs on onTerminate and onLowMemory but non of these get called before Instance get killed.

Please advice.

public class Instance extends Application {
  @Override
  public void onCreate() {
    super.onCreate();
  }

  @Override
    public void onTerminate() {
        super.onTerminate();
        Log.e(TAG, "onTerminate");
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
            Log.e(TAG, "onLowMemory");
    }
}

That is fully expected behavior in Android OS. If you need smth to track some app’s state, then you need to use some persistance means: file storage, shared preferences or ContentProvider. More details on this here: https://stackoverflow.com/a/4642069/247013
