@ikeremozcan I bumped into the exact same issue. Did you manage to solve it somehow?

[ikeremozcan]

I solve it by saving stream in a file @gogolon. Then play audio from the file

I have the same problem. I can not get files mp3 to play in android emulator. This line works on windows but not in android for me: await CrossMediaManager.Current.Play("https://ia800806.us.archive.org/15/items/Mp3Playlist_555/AaronNeville-CrazyLove.mp3");

I have .net 8 and android 13 I get: Java.Lang.RuntimeException: 'Can't create handler inside thread Thread[Thread-13,10,main] that has not called Looper.prepare()'
