How to ICE Restart in Android peerconnection client?

Question

Answer 1

As the android peer connection object doesn't have any icerestart() method we have to do a workaround in our code to re-establish the connection.

Steps should be:

1. Put additional constraint:

constraints.mandatory.add(new MediaConstraints.KeyValuePair("IceRestart","true"));

2. Create offer again using that constraints:

peerConnection.createOffer(new YourSdpObserver(),constraints);

3. Set generated sdp to peerConnection using setLocalDescription.:

peerConnection.setLocalDescription(new YourSdpObserver(),sdp);

4. Send it to the remote peer.
