But there doesn't seem to be a solution valid for all cases, then. onResume() will also be called each time I launch the activity. Or it's shown at the foreground, because something which was in front of it was closed. This is not what I want. onCreate() with LAUNCHER category will be called only when the app is indeed created, but this will not be always the case when user opens the app. And in the last case (Application onCreate) there's also the problem that the application will not necessarily be created when the user launches it.
