So, I have been stuck with this problem for a while. I am planning to build an app where I can play the audio of multiple apps together for example, I play a spotify song and then play a song saved on my drive. Now what I want is to play both the songs simultaneously without one audio stopping the other, so similarly for example listen to a spotify song and see a youtube video where I can hear both the song and the audio of the youtube video simultaneously.
I have been using shizuku to grant special audio focus permission and even successful in setting up shizuku and getting the audio focus permission but it is lost immediately as I play any audio. Need help to fix this and eventually add sliders to control the volume of the audio coming from each of the apps.
Let me know if anyone can help me with this. I might not be able to reply everyone therefore, I am sharing the GitHub of the app, where I have explained everything in the Readme.md
