Answer 1

Does your application have to be an activity? Can it utilize a background service?

Answer 2

If you use a Service and make sure it stays active (by first starting it and simply not stopping it) the application wont be killed (unless it's extremely low on memory of course).

Answer 3

You should use a service instead of using an Activity to do work in the background.
