Being a big nerd, and having an rpi3 laying around, I gave this a try this weekend. I installed LineageOS Android 9, Google play store via a gapps pico installation, and TrainerRoad installed after that just fine. Have an ANT+ dongle, but the Kickr and HR strap connected fine via Bluetooth.
So, technically it all works fine. But holy moly is the entire endeavor a test of patience. Android is slooow on the rpi3. Anything, really anything, is better than this. Grab the cheapest Android tablet you can find and use that. If Android could be more optimized for the rpi3, that would change things, especially if hardware video acceleration was working, but I’m pretty sure I’ll be wiping the installation, was neat to try out though.
