Сбой webRTC на peerConnection.dispose()

Я занимаюсь разработкой приложения для видеочата с использованием собственного WebRTC с моим сервером Java Signaling.

У меня есть успех создать связь, и она работает очень хорошо.

НО, когда я пытаюсь отключить звонок, приложение падает со следующим сообщением об ошибке:

Сбой происходит, когда я вызываю peerConnection.dispose() или peerConnection.close();

Вот мой код для отключения вызова:

    private void callDisconnect() {
    if (peerConnectionFactory != null) {
        peerConnectionFactory.stopAecDump();
    }
    Log.d("ZCF", "Closing audio source.");
    if (audioSource != null) {
        audioSource.dispose();
        audioSource = null;
    }
    Log.d("ZCF", "Stopping capture.");
    if (videoCapturer != null) {
        try {
            videoCapturer.stopCapture();
        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }
        videoCapturer.dispose();
        videoCapturer = null;
    }
    Log.d("ZCF", "Closing video source.");
    if (videoSource != null) {
        videoSource.dispose();
        videoSource = null;
    }

    Log.d("ZCF", "Closing peer connection.");
    if (peerConnection != null) {
        peerConnection.dispose();
        peerConnection = null;
    }

    Log.d("ZCF", "Closing peer connection factory.");
    if (peerConnectionFactory != null) {
        peerConnectionFactory.dispose();
        peerConnectionFactory = null;
    }

    rootEglBase.release();
    Log.d("ZCF", "Closing peer connection done.");
    PeerConnectionFactory.stopInternalTracingCapture();
    PeerConnectionFactory.shutdownInternalTracer();
}

Я попытался сначала вызвать peerConnection.dispose(), но он все еще не работал. Что бы ни пытались, это всегда сбой со следующим:

I/org.webrtc.Logging: NetworkMonitorAutoDetect: Unregister network callback

что я делаю не так?

Я исправил эту проблему, удалив peerConnectionFactory перед peerConnection.

@Override
public void disconnect() {

    if(executor == null) return;

    executor.execute(() -> {

        localVideoTrack.dispose();
        localVideoSource.dispose();
        localAudioTrack.dispose();
        localAudioSource.dispose();
        peerConnectionFactory.dispose();
        peerConnection.dispose();
    });

    executor.shutdown();
}

Я в onResume() добавляю NetworkMonitor.getInstance().startMonitoring(getActivity()); не найти эту аварию
