Chromecast app only shows Receiver Application URL

I am adding Chromecast to an Android app, which is not streaming media. So I base my code on the tutorials and the "CastHelloText" sample project according to the instructions from Google. I can run the app, press the cast button and then cast to my TV.

But the only thing I see is the webpage for the Receiver Application URL, which I wrote for the "Custom receiver" in the developer console. I never see the content of the app on the TV, just the webpage for the URL.

How can I proceed to cast the app, not the URL? I have read Google's tutorials and information about Chromecast, but it is difficult to find a straight approach on how to get this to work.

What do you mean by "cast the app"? Do you want to cast the entire sender screen to the receiver (like the Google Cast app's Cast Screen / Audio feature), or cast a single view (e.g., for your music visualization app, the remote display would only show the visualizer view, without any extra material)? – plátano plomo

If you want to "mirror" a certain view in your app on a cast device, you'd need to use the Remote Display Apis, and that, by the way, doesn't need a custom receiver. I don't know what documentation you have read but the best starting point would be the official cast documentation for developers.
