Below information is from Developer Android side
Note: Neither setAndAllowWhileIdle() nor setExactAndAllowWhileIdle() can fire alarms more than once per 9 minutes, per app.
I want to be more clear for this case.
Example case:
I use AlarmManager with method setExactAndAllowWhileIdle() to set two alarms, first Alarm is 7:30 and second Alarm is 7:35. (device is in Doze mode at this time)
As you can see, the time delta is 5 minutes, less than 9. So second alarm will waiting 9 minutes in order to be fire off at 7:39 or it can't fire any more?
For a reminder app, should I check and alert user if there are two alarm which time different is less than 9 minutes and ask them set another time?
By the way, is setAlarmClock() always work for this case?
Thank you for your advice.
