localdesktop/localdesktop.github.io — reverse-engineered prompt

Build me an Android app that lets me run a real desktop Linux environment directly on an Android tablet or phone. It should install an ARM64 Arch Linux filesystem inside the app, start it without requiring root, and show a usable desktop session inside the Android app window.

The goal is for someone with a tablet, DeX style setup, keyboard, and maybe a mouse to open the app and get a Linux desktop with no complicated setup. It should use a proot style environment, launch Xwayland and a lightweight desktop like XFCE, and render through a minimal Wayland compositor in the native Android activity.

Please make it buildable into an APK from the repo, ideally from Termux on Android and also from a normal computer or Docker. Keep the first version focused on “install and go”, reliable startup, basic input, display rendering, and clear errors if something fails. Look up current Android and Rust build docs online if you need to.
