Android - Repeating Alarms Allowed While Idle

Question

I need to set a repeating alarm every X hours that would even fire in doze mode. However, the only Apis available in AlarmManager for Android 23 are setExactAndAllowWhileIdle and setAndAllowWhileIdle which are not for repeating alarms.

I am wondering if I should reschedule the alarm every time it fires? or is there any better solution?

Can this still be done in Oreo and above.`setExactAndAllowWhileIdle` and set a repeating alarm every X interval that would even fire in doze mode. Does anyone has a sample how can I do that. — Valentin Gjorgoski, Aug 28 '19 at 12:18

That is exactly what you should do.

The idea behind doze is to attempt to prevent draining the battery. Repeated alarms drain battery, so the builtin way to repeat alarms by passing an extra parameter was removed in android 6. It can still be done, but as you were wondering, that requires you to manually reschedule the alarm.

Be sure to reschedule the alarm immediately when it fires, before doing anything else that could go wrong and prevent the alarm from being rescheduled.

Which method gets called to set this up? Are you supposed to call `setAndAllowWhileIdle()` or something else? – Etienne Lawlor Mar 30 '17 at 06:11
Does this bypass Background Execution Limits in Oreo? I doubt it. I use this and still Android says Background start not allowed: service – NinjaCoder Nov 04 '17 at 23:45

@NinjaCoder I don't see how that is related to scheduling alarms – Tim Nov 05 '17 at 22:40
My bad. I was confusing this answer with scheduling alarms with service in `PendingIntent` – NinjaCoder Nov 05 '17 at 23:45
