webrtc-conferencing-1v3-connectionFactory.dispose(

问题:

I am trying to create a 1v3 or 4v4 conferencing(whatever you call it) android app, i have successfully connected 4 people together using webrtc and socket.io. But when i disconnect one of the users i get webrtc native crash

Fatal signal 11 (SIGSEGV), code 1, fault addr 0xb8 in tid 17650 (Thread-648)

Same code works in moto c but crashes on other devices.

webrtc version used - compile 'io.pristine:libjingle:9694@aar'

 onDisconnect(){
   if (null != peerConnection2) {
        peerConnection2.removeStream(localMediaStream);
        peerConnection2.close();
        peerConnection2 = null;
    }
    if (null != peerConnection3) {
        peerConnection3.dispose();
        peerConnection3 = null;
    }
    if (null != localVideoSource) {
        localVideoSource.dispose();
        localVideoSource = null;
    }
    if (null != peerConnectionFactory) {
        audioManager.setMode(AudioManager.MODE_NORMAL);
        audioManager.setSpeakerphoneOn(false);

        peerConnectionFactory.dispose();  <<<<--- THIS IS WHERE THE APP CRASHES.
        peerConnectionFactory = null;
    }
}

I am not sure if updating the version will help me with this bug, even if i go for updating it to new version, i am unable to find any proper documentation or blog related to it, it'll be great if you can point me to any known link(blog/documentaion) for latest version of libjingle.
