I tried a few months ago on a Samsung Chromebook, and the way that the Chromebook sandboxed networking around the Android emulator made it impossible for Roon Remote to communicate with the Roon core over the Local LAN.
Maybe someone has gotten better results or figured out how to hack around it. Not sure. It wasn’t my Chromebook, so I spent an hour or two fooling around and then ran out of avenues and gave up.
