Hi, I'm happy to hear that you wish to contribute to Arch Linux.
If you should be interested, there is an Android application for Arch Linux maintainers that could need a few improvements (notifications when packages are out of date, for instance). It could also be expanded to support AUR somehow. It's not a world-class Android application, but if you find it interesting, it may be a starting point. https://github.com/xyproto/archfriend Patches are welcome. :) -- Best regards, Alexander Rødseth xyproto / TU
