In kurento android, after joining the room for group video call, whenever someone connects and starts streaming, the function

onRemoteStreamAdded(MediaStream mediaStream, NBMPeerConnection nbmPeerConnection)

is called, and I can simply attach the mediastream with a videorenderer and it works. But when I join the room with existing peers publishing their videos, no media streams show up, but sdp offers are generated. How do I get video stream from all the users in the room using sdp offers?

@aditya i have worked on M2M streaming . I have done like this :-

  @Override
public void onRoomResponse(RoomResponse response) {
    int requestId = response.getId();
    boolean check = false;
    for (Map.Entry<Integer, String> entry : videoRequestUserMapping.entrySet()) {

        if (entry.getKey() == requestId) {
            check = true;
        }
    }
    if (check || (requestId == publishVideoRequestId)) {

        SessionDescription sd = new SessionDescription(SessionDescription.Type.ANSWER,
                response.getValue("sdpAnswer").get(0));

        if (callState == CallState.PUBLISHING) {

            callState = CallState.PUBLISHED;
            nbmWebRTCPeer.processAnswer(sd, "local");
            mHandler.postDelayed(offerWhenReady, 2000);

        } else if (callState == CallState.WAITING_REMOTE_USER) {
            callState = CallState.RECEIVING_REMOTE_USER;
            String connectionId = videoRequestUserMapping.get(requestId);
            Log.e("ConnectionId", ":" + connectionId);
            nbmWebRTCPeer.processAnswer(sd, connectionId);
        } else {

            callState = CallState.RECEIVING_REMOTE_USER;
            String connectionId = videoRequestUserMapping.get(requestId);

            nbmWebRTCPeer.processAnswer(sd, connectionId);
        }
    } 
}

hi first you need to close the connection when someone leaves the group using

nbmWebRTCPeer.closeConnection("username");

you can manages on this method :

 public void onIceStatusChanged(PeerConnection.IceConnectionState     iceConnectionState, NBMPeerConnection nbmPeerConnection) {
 if (iceConnectionState.name().equalsIgnoreCase("CLOSED"))  
   {
   nbmWebRTCPeer.closeConnection(nbmPeerConnection.getConnectionId());
   }

}
