Hi i have the same problem. Have you found a solution? Thanks

I've got the same problem when using OWT android client demo with M104 libwebrtc on Android 10+ emulator in Android Studio.

From the stack trace, seems i need to put new LocalStream call into a foreground service? But how can the local stream ref connected to other code?
