I want to build a custom media player app for Android TV. It's not for phones or tablets, it's specifically designed for devices like the Nvidia Shield, Fire TV sticks, and Chromecast with Google TV.

The main feature is that it should let you watch content from public sources, but with a much better experience. It needs a clean user interface that is optimized for navigation with a TV remote. It should also have a built-in SponsorBlock to automatically skip sponsored segments inside videos. Let's make sure it supports high-quality playback up to 8K, with HDR and 60fps options, plus adjustable playback speed.

A critical requirement is that this app must not depend on Google Play Services to function. Build this as a native Android app using Java and Kotlin. Finally, please include a simple self-updating mechanism so the app can check for and install new versions on its own.
