Answer 1

I think you'd be better off using android.app.AlarmManager to schedule a wakeup alarm. Be careful though - you don't want to do any long-running work in your onReceive() method as that's normally called on the main thread, and will hang your activity. You'll still need to acquire the wakelock for the duration of your task to prevent the phone sleeping part-way through.

Answer 2

Follow the pattern Mark Murphy provides with the WakefulIntentService. I would suggest picking up his books, not only for the detailed explanation of this class and example he includes in one of them, but for the other wealth of information you'll find in them.

I just recently implemented this pattern for my main app and this class works like a charm.

I dont think you are using the correct flag accorinding to the android documentation fior PowerManager:

*If you hold a partial wakelock, the CPU will continue to run, irrespective of any timers and even after the user presses the power button. In all other wakelocks, the CPU will run, but the user can still put the device to sleep using the power button.

In other words, try using PARTIAL_WAKE_LOCK as this is the only one that gurantees the cpu to run
