Basically, use Kivy. There is a udemy course that started me off with Kivy.

First Steps

from kivy.app import App
from kivy.uix.label import Label


class Main(App):
    def build(self):
        return Label(text='Hello World')


Main().run()

I've never actually done any of this, and likely won't. Android development isn't on my near-future todo-list.
