Toolchain for building APKs for python projects.
pip install python-for-android
main.py is your entrypoint. To build an APK:
p4a apk --private . \ --name TGG \ --package net.kahowell.tgg \ --version 0.1.0 \ --bootstrap=sdl2 \ --requirements=python2,kivy

Wraps Java code into python wrappers
# example from https://pyjnius.readthedocs.io/en/latest/android.html#using-texttospeech from jnius import autoclass Locale = autoclass('java.util.Locale') PythonActivity = autoclass('org.renpy.android.PythonActivity') TextToSpeech = autoclass('android.speech.tts.TextToSpeech') tts = TextToSpeech(PythonActivity.mActivity, None) # Play something in english tts.setLanguage(Locale.US) tts.speak('Hello World.', TextToSpeech.QUEUE_FLUSH, None)

# not necessary for webview app class MyApp(App): def on_pause(self): pass # save state here
