Activities can't be executed when not in foreground.

But, if you have a Service working for the activity, it will, and then when your activity come back to foreground it will get the updates the service did.

once you start a service, it can be stoped only by the system (in case of low device resources) or if the user want to stop it.

So, I think, that for your problem you should implement a Service, to work in background for your activity.

No you cant, onPause() is in the lifecycle of the activity... you cant skip it,
