I have an existing Android TV app that already relies on ExoPlayer. I now need a straightforward way to play YouTube videos inside that same player and, at the same time, bring the project up to the latest stable SDK versions. Scope (keep it lean and focused): • Embed MY YouTube video playback (which is sent via an api) in ExoPlayer with reliable streaming on Android TV. • Upgrade the project’s Android SDK and ExoPlayer libraries to their current releases, fixing any breaking changes that appear. • Supply a clean, runnable sample activity in my codebase that demonstrates basic playback controls (play/pause/seek). Advanced extras like 4K, captions, or playlists are nice-to-have but not required for this first pass. • Document any API keys, permissions, or Gradle settings you add so I can compile the build locally. I will provide the existing source and a test YouTube URL as soon as you start. A short read-me that tells me “clone, build, run” is all the documentation I need.
