Answer 1

You need a WakeLock. There are different kinds of wake locks so be sure to select the least aggressive one that meets your needs. In particular it sounds like you need a Partial Wake Lock.

Partial Wake Lock - Wake lock that ensures that the CPU is running. The screen might not be on.

Also, make sure you add the permission android.permission.WAKE_LOCK to your manifest. And finally be double sure to Release your lock when you are done.
