Even after a restart? Would you have a chance to share the log (if you know how to do it)
weirdly, if I show the open apps, it's there, but if I try to switch to it it just jumps back to the 'desktop'.
Yeah, tried multiple times, even killed the app and retried. Same result.
Somebody on reddit said it was using ART and crash. Without it it work. Try without it maybe? I didn't got a chance to test a Kivy application with ART yet.
Ah yeah I'm using ART. It takes 30 min to rebuild everything for Dalvik, bit too much effort when I'm out and about. Unlucky! Usually most apps work fine under ART.
