Android Sinch Video Call cannot switch camera and resume video monitoring

Question

I am developing an Android video call using Sinch, and I am following Sinch training materials and samples. Most of them work fine, but I ran into two problems that I have no idea how to solve them.

1) I can not resume rendering the video. Scenario: When I set up the call, everything works fine, then I exit the operation without freezing (so the video call still continues). When I restart my work again, localview (my own camera) will not continue rendering. This makes the other phone see me as if the video call is stuck / stuck.

    @Override
    public void onServiceConnected(ComponentName name, IBinder svc)
    {
         service = ((ServiceChat.ChatBinder) svc).getService();
         VideoController controller = service.GetSinchVideoController();
         if(controller != null)
         {
             // your own face
             localVideo.addView(controller.getLocalView());
             // contact face
             remoteVideo.addView(controller.getRemoteView());
         }
    }
    @Override
    protected void onDestroy()
    {
        VideoController controller = service.GetSinchVideoController();
        if(controller != null)
        {
            localVideo.removeView(controller.getLocalView());
            remoteVideo.removeView(controller.getRemoteView());
        }
        super.onDestroy();
    }

2) Another problem that I am facing is that I cannot switch the camera

private void SwitchCamera()
{
    VideoController controller = service.GetSinchVideoController();
    if(controller.getCaptureDevicePosition() == Camera.CameraInfo.CAMERA_FACING_FRONT)
    {
        controller.setCaptureDevicePosition(Camera.CameraInfo.CAMERA_FACING_BACK);
    }
    else
    {
        controller.setCaptureDevicePosition(Camera.CameraInfo.CAMERA_FACING_FRONT);
    }
    //controller.toggleCaptureDevicePosition();
}

but i got this error

org.webrtc.Logging: VideoCapturerAndroid: Ignoring camera switch request.
org.webrtc.Logging: VideoCapturerAndroid: Could not switch to camera with id 0

VideoController vcLocal = getSinchServiceInterface().getVideoController();

vcLocal.toggleCaptureDevicePosition();
