I'm beginner in kivy library programming, but I have done very simple application, like in Kivy tutorial. On desktop it works cool. But than I wanted to do .apk file(Hadn't used Linux). I've tried a lot of steps to do an .apk file, but finally when I've installed and opened this program. It had an error. I've tried a lot of specs and new_android, but nothing worked. Finally I've updated my buildozer to the last version. But now, after buildozer android debug, he writes this error:
IOError: [Errno 2] No such file or directory: u'/home/kivy/reyyy/.buildozer/android/platform/build/dists/RetroApp/build/outputs/apk/RetroApp-debug.apk'.
