redphx/better-xcloud-android ? reverse-engineered prompt

Build me an Android app for Xbox Cloud Gaming and Remote Play that makes the experience feel smoother than using a browser. I want it to support the same features as the Better xCloud userscript, run light and fast, use less battery, and handle controller vibration properly. It should also automatically keep the screen refresh rate at 60Hz while gaming, and it should be set up so custom userscripts can be used too.

Make it feel like a polished app people can actually install and use, with a simple launcher flow into xCloud, a clean settings screen, and support for Android TV as much as possible. Keep the app small and responsive, and if you need current Android or webview guidance, look up the latest docs online. Focus on making the whole thing reliable and easy to use, like a better dedicated client for Xbox cloud gaming rather than just a wrapper.
