lizongying/my-tv ? reverse-engineered prompt

Build me a simple Android TV app for watching live television, focusing on Chinese broadcast channels. The interface should be really clean and straightforward. When I open it, I want to see a channel list on the left side of the screen. When I click a channel, the live stream should start playing in the main area on the right.

Please add a feature to save my favorite channels into a separate list for quick access. It would also be great to have on-screen controls for volume and brightness. The app should be built as a single APK that can be easily sideloaded onto an Android TV box. Let's also include a function for the app to check for its own updates and notify the user. The main goal is an app that's super easy to install and use for watching live TV with no complicated setup.
