My app has audio playback functionality. I need to continue playback in a background when the app exited as a result of another app being launched. I also need to detect that previous instance of my app is already running (playing audio in a background) when my app is launched. In this case I need to instruct that background instance to show full UI (and continue playing audio). The just launched instance must now exit quietly. I believe it is quite straightforward requirements, I do not see anything fancy.
