Relaying a remote stream in native Android

[Dean Wild]

One of the javascript samples demonstrates relaying a remote media stream onto another separate peer connection.

https://webrtc.github.io/samples/src/content/peerconnection/multiple-relay/

It works by simply adding the remote media stream to another peer connection.

I'ver tried replicating this in my native android app using libjingle but it does not work. I take the remote mediastream from a successful peer connection and try to add it to a second peer connection. Unfortunately the addStream() method just returns false and the stream is never added to the second peer connection.

peerConnection2.addStream(remoteStream) // returns false

Am I missing something simple or does the native library not support this?
