How to avoid interrupting background music

Hello,
Players of my game are complaining that if they start my game whilst listening to music or podcasts the playback stops and my game takes over the Audio. Is there a way to prevent this and continue playing back the audio from the background apps and add my game’s audio on top of it?

I assume there will be different solutions for Android and iOS. I am interested in both, but in this thread primarily in Android.

Cheers!
