Allowing the phone to sleep while using RTC alarm on Android

Question

I\'ve been seeing some strange issues using the Alarm manager in Android, despite the fact that I\'m using RTC (non Wakeup) the phone will reliably send the PendingIntents o

Answer 1

I've just spent an hour trying to find out why my RTC alarm sends PendingIntents even when my phone is sleeping. And the answers is very simple, because it was pluged with USB so the phone had status "charging".

Presumably something else was having the device awake at those moments.

A lot of applications with notification ads (like AirPush, Leadbolt ect) wake up the device.

Answer 2

Why was my service executing?

Presumably something else was having the device awake at those moments.

If another service is misbehaving and using the _WAKEUP variants of the alarm will my service wake up too?

Yes, though "misbehaving" is in the eye of the beholder.

Can I avoid being woken by another service, and just awake from the user turning the screen on?

Not directly via AlarmManager. You can watch for ACTION_SCREEN_OFF and ACTION_USER_PRESENT broadcasts, and perhaps disable your alarms between those.
