Introduction

In terms of comparaison, you can check how Python for android can be useful compared to other projects.

Project Native Python GUI libraries APK generation Custom build
Python for android Yes Yes Yes Yes
PGS4A Yes Yes Yes No
Android scripting No No No No
Python on a chip No No No No

Note

For the moment, we are shipping only one "java bootstrap" needed for decompressing all the files of your project, create an OpenGL ES 2.0 surface, handle touch input and manage an audio thread.

If you want to use it without kivy module (an opengl es 2.0 ui toolkit), then you might want a lighter java bootstrap, that we don't have right now. Help is welcome :)

How does it work ?

To be able to run Python on android, you need to compile it for android. And you need to compile all the libraries you want for android too. Since Python is a language, not a toolkit, you cannot draw any user interface with it: you need to use a toolkit for it. Kivy can be one of them.

So for a simple ui project, the first step is to compile Python + Kivy + all others libraries. Then you'll have what we call a "distribution". A distribution is composed of:

  • Python libraries
  • All selected libraries (kivy, pygame, pil...)
  • A java bootstrap
  • A build script

You'll use the build script for create an "apk": an android package.
