title: Casting from Android - can you cast an entire app or only media content within the app
body: <p>I'm looking through the chromecast api and trying to figure out whether I can cast an entire android app on to the screen, or only media within that app. Does anyone know the answer to this? I want to make sure if I build a cast app, that the entire app can be sent to a tv screen, not just media contained within it.</p>
