Hi Jon,

I am not using Zoom video SDK in my project. I am still evaluating it for my use case.  
I am using this sample project bundled with the downloaded video SDK “zoom-video-sdk-android-1.1.2/Sample&Libs/mobilertc-android”.

You can easily reproduce the issue by following the below steps:

1. Paste below code in `BaseSessionActivity` class

```auto
ZoomVideoSDKVideoSource source = new ZoomVideoSDKVideoSource() {
    @Override
    public void onInitialize(ZoomVideoSDKVideoSender sender, List<ZoomVideoSDKVideoCapability> list, ZoomVideoSDKVideoCapability ZoomVideoSDKVideoCapability) {
            System.out.println("sender:" + sender); // This line is not called during initialization
    }

    @Override
    public void onPropertyChange(List<ZoomVideoSDKVideoCapability> list, ZoomVideoSDKVideoCapability ZoomVideoSDKVideoCapability) {

    }

    @Override
    public void onStartSend() {

    }

    @Override
    public void onStopSend() {

    }

    @Override
    public void onUninitialized() {

    }
};

```

1. Set external video source

```auto
params.externalVideoSource = source;

```

Please let me know if you need more details.
