Avoid calling onPause() when there is no window focus

Question

I'm designing an app for an Android device with NO SCREEN! Naturally the problem is that I have no window focus (I have no screen)
hence onPause is called right after onResume.

For testing, I use a controlled PC with a simulated UI layout, but when I lose
screen focus or run without the simulated UI on my device, onPause is called.

I tried some window manager flags to help me but none of them helped me. Anybody tried an app without screen or can help?

It might be possible to get your job done with an Activity but you would probably make your life unnecessarily miserable. I think what you are looking for is a Service or maybe a BroadcastReceiver. Check the official documentation on Services and Broadcast receivers.
