The Chaquopy SDK is the easiest way to use Python in your Android apps. It's distributed as a plugin for the standard Android build system. Download and installation is automated via Gradle and takes only 5 minutes.

This open-source app is a demonstration of what you can build with Chaquopy. It includes:

* A REPL (read-eval-print loop) for interactive experimentation.
* An example of an Android activity written entirely in Python.
* An example of how to use a Python library in a normal Java activity.
* The SDK's complete unit test suite.

The core of Chaquopy is a lightweight but flexible Python/Java language interface allowing you to access Java from Python or Python from Java. Freely intermix the two languages in your app using whichever one is best for each situation. Most PyPI packages can also be automatically downloaded and built into your app.
