Create a package for Android for Kivy. I think I need to take a closer look at Kivy. They are now working with Python for Android, their own Python distribution that brings a customized interpreter for Android and a coupling via Cython, NDK, and JNI to the Android SDK. This way, you can produce real APKs that can be installed normally on devices - but write everything that makes up the application itself in Python. Of course, the question remains how fast it will run - Python is interpreted after all. But it would definitely be interesting for tools, especially since you can also run Kivy applications more or less directly under desktop systems.
