App AlarmManager not working after clearing App Data

I wish to show a status bar notification at 12 pm everyday and hence, I'm creating an AlarmManager which fires an IntentService which will show some notification.

I've added Boot completed receiver and the AlarmManager is registered when the app gets lauched. Everything is working fine and the Notifications are shown everyday at 12 pm even when app is not in foreground (expected behaviour).

The problem is, whenever I clear the App data in Application settings, The AlarmManager no longer triggers the Application notifications. However, When I launch the app again, the App starts working with the notifications everyday with an expected behaviour.

Could anyone please help me with this issue? Is there a workaround to ensure that AlarmManager is triggered irrespective of these conditions.

This is normal behaviour. If the user voluntarily force stops or clears the data of the application,then it should be stopped. android system kills the entire task ,No services or broadcasts are allowed to run until an activity is run again. so you can't do anything to prevent this. see the qn answered here.

No. When you press 'Clear data', not only is the app's data cleared, its processes are also killed. When that happens, scheduled alarms are killed with it.

It's not strange that this happens. A running app might need data that you cleared, if it doesn't find that data, it could crash. Killing the app will prevent those crashes.
