buildozer

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

Trying to run Kivy with buildozer on Ubuntu 16.04, (startup-demo-project pong) I get an error on command buildozer android debug deploy After: .... [DEBUG]: BUILD SUCCESSFUL .... at the end of the build there is an error message: .... IOError: [Errno 2] No such file or directory: u'/home/std/Dokumente/python /Kivy/.buildozer/android/platform/build/dists/myapp/build/outputs /apk/myapp-debug.apk' My installation is according to: http://buildozer.readthedocs.io/en/latest/installation.html for Ubuntu 16.04. Also buildozer serve does not show anything useful, only: Directory listing for / as
