We built an audio-only demo called Party Line with multi-platform support from day one, targeting Android audio applications which has been notoriously limited. We initially encountered a problem where the app wouldn't work in the emulator but would on physical devices and lower API levels. After ruling out mic permissions issues, we used the WebRTC troubleshooter to identify a networking issue suggested by a socket layer problem and found an error message in Logcat indicating SELinux was preventing communication with the socket. We granted read privileges using the audit2allow command and successfully fixed the issue, allowing us to build out the full Party Line codebase.
