Be careful. You are using one of the possible ways to run Kivy-based software using the Kivy launcher . This launcher requires installing your application ( main.py ) and a description file ( android.txt ) in the kivy/yourapp on your SD card.
So, in /mnt/sdcard OR /sdcard make sure you have the kivy directory + the directory for your application + main.py + android.txt .
If you want to create a standalone APK, you need to use the python for-android project.
