Since I'm using AlarmManager
to perform periodical widget update, I need to ensure onEnabled
& onDisabled
will work reliably.
However, I realize they will not be triggered sometimes. I'm not the only one who is facing this problem.
Android appWidgetProvider onEnabled never called on tablet
- Is there any official bug ticket submitted to Google Android team?
- Is there any workaround, especially
onDisabled
? As I do not want AlarmManager still being triggered repeatably, after the last widget had been removed.

alarmManager.setRepeating(AlarmManager.RTC, System.currentTimeMillis() + scanSpeed, scanSpeed, pendingIntent);
