Customize Chromecast Dialog

You can customize the appearance of the VideoMediaRouteControllerDialog which appears when you click on the MediaRouteButton when casting.

You can do this by overriding the custom_media_route_controller_controls_dialog.xml layout file.

As an example, here is the custom_media_route_controller_controls_dialog.xml that we use in our demo app:
