WebRTC crash when I try to end a call (close connection)

In android implementation of WebRTC, I have checked multiple discussion all of those mention about unloaded .so files I have even tried using https://github.com/KeepSafe/ReLinker to keep hold on these .so file.

Here is crash log for the issue:

According to the bug reported here and here, it seems that you need to create the peerConnectionFactory only once. Each time it is created it tries to create an audio device module, but only one is supported on Android.

Also (if using MediaSoup) make sure you create only a single Device and free it when done.

Many thanks to Dhilip from https://stackoverflow.com/a/30803727/656600. His solution on his own question(about objective C) helped me. I am quoting his suggestion here:

I was trying to create PeerConnectionFactory and LocalVideoTrack in worker thread! Problem solved when I moved those to main thread.

Based on that suggestion I updated my code to:

Handler handler = new Handler(Looper.getMainLooper());
handler.post(() -> {
    peerConnectionClient.createPeerConnectionFactory(getActivity(),peerConnectionParameters, this);
});

This fixed the crash for me. I am still looking for explanation on this. So please add details if you know.
