  view) {
    Log.d(TAG, "initializeAndJoinChannel: ");


    try {
        mRtcEngine = RtcEngine.create(getBaseContext(), appId, mRtcEventHandler);
    } catch (Exception e) {
        throw new RuntimeException("Check the error.");
    }

    // By default, video is disabled, and you need to call enableVideo to start a video stream.
    mRtcEngine.enableVideo();

    FrameLayout container = findViewById(view);
    // Call CreateRendererView to create a SurfaceView object and add it as a child to the FrameLayout.
    SurfaceView surfaceView = RtcEngine.CreateRendererView(getBaseContext());
    container.addView(surfaceView);
    // Pass the SurfaceView object to Agora so that it renders the local video.
    mRtcEngine.setupLocalVideo(new VideoCanvas(surfaceView, VideoCanvas.RENDER_MODE_FIT, 0));

    // Join the channel with a token.
    mRtcEngine.joinChannel(token, channelName, "", 0);

    return mRtcEngine;
}
