It looks like Google made some changes and the apk isn't valid anymore. I didn't change anything so I'll have to find out what Google changed and generate a new apk. I hope it's a quick fix.
Nice! Controller support is probably spotty because the buttons need to be adjusted manually in some menus. I haven't done any extensive testing with controller, so it's probably broken in a few places. But if you (or anyone else) find any issues let me know, they're usually very easy to fix.
