I have a requirement where I need to notify inactive users (who have not opened the app for 7 days). This means the notification must be sent if the app is in background for 7 days or the app has been killed and not used for 7 days.

I followed an algorithm using AlarmManager similar to this answer but the notifications are not sent if the app gets killed. I tried to integrate BroadcastReceiver as shown below but it creates an infinite loop when I call it from OnDestroy() of CheckRecentRunclass (because it destroys itself periodically). Also, as I learnt from this answer, onDestroy() does not always get called when app is killed.

public class TimerRestarterBroadcastReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
    Log.i(TimerRestarterBroadcastReceiver.class.getSimpleName(), "Service has stopped");
    context.startService(new Intent(context, CheckRecentRun.class));
}
}

Is there any simpler and effective way to do this?

Possible scenario using WorkManager:

  • You create a task that send notification in 7 days
  • Every time user uses app change time of the old task to a new one after 7 days
