This is a really interesting approach - thanks for sharing.

I’ve been doing something similar recently with VOC [1]. I’m targetting
Java bytecode rather than Dalvik, but with a similar end goal: to take
Python source code, and deploy it to Android as a native application
without needing to use the Android NDK. A couple of weeks ago I published a
video showing a native iOS, Android and single-page web app, all doing the
same thing running on Python [2], using this toolchain (plus some other
tools).

Of course, you’ve got the added bonus that you don’t need the Android SDK
either, which would be a huge win in my book. What’s the impact of
Android’s move to ART on this approach?
