OK
Python for android ended.

The app was tested build without kivy or flask requirements so the service unit test would be ran:

python setup.py apk --ndk-dir ~/.buildozer/android/platform/android-ndk-r19c/ --sdk-dir ~/.buildozer/android/platform/android-sdk/ --arch=armeabi-v7a --debug --requirements sqlite3,libffi,openssl,pyjnius,python3,requests
