As issue link:
UsageStatsService.onDisplayChanged executed in system main thread,
If calling UsageStatsManager.queryEvents with too many events before it

too many activity resume / pause events or configuration change
during monkey test),
System will be blocked then watchdog timeout.
Let display listener executed in background thread handler
