Build me an Android media player app based on mpv, with a much nicer and more modern interface than the usual player.

I want it to feel polished and easy to use, with clean controls, good looking screens, and smooth picture in picture playback. Please include playback history that works well, simple customization options, a sleep timer, and a few speed presets so I can quickly change playback speed. It should be built with a modern Android UI style and feel responsive and pleasant on phones.

Make it something I could actually use day to day for watching local or streamed media, and keep the experience focused on playback first. If you need to check current docs or best practices while building it, feel free to look them up online.
