Android AlarmManager stops when activity die

Answer 1

This is only a guess but I think the issue has to do with the API. Starting with KitKat, the system messes up the AlarmManager. Perhaps consider trying using something else for systems at abd above kitkat.

"Note: Beginning with API 19 (KITKAT) alarm delivery is inexact: the OS will shift alarms in order to minimize wakeups and battery use. There are new APIs to support applications which need strict delivery guarantees; see setWindow(int, long, long, PendingIntent) and setExact(int, long, PendingIntent). Applications whose targetSdkVersion is earlier than API 19 will continue to see the previous behavior in which all alarms are delivered exactly when requested. "
