Description
The WorkManager lib schedules and alarm to track if it was force stopped. This happens in the ForceStopRunnable class (see also: https://android.googlesource.com/platform/frameworks/support/+/a9ac247af2afd4115c3eb6d16c05bc92737d6305/work/workmanager/src/main/java/androidx/work/impl/utils/ForceStopRunnable.java) which will run during initialization of the WorkManager. On some Samsung devices this will trigger a SecurityException, and as far as I know Samsung throws this exceptions when your apps schedules more than 500 alarms. The app isn't full of alarms, so i think FLAG_UPDATE_CURRENT will keep an old instance in memory of the cancelled version. But I haven't been able to reproduce this, and I don't see multiple copies of the alarm scheduled either.
Happens only on SDK 28 and some rare cases on SDK 29
Question
Does anyone else here have the same experience working with the WorkManager Library and knows a way how to reproduce this issue?
Is there a work-around for this issue?
