The Android Scripting Environment (ASE) brings scripting languages to Android by allowing you to edit and execute scripts and interactive interpreters directly on the Android device. These scripts have access to many of the APIs available to full-fledged Android applications, but with a greatly simplified interface that makes it easy to:
Handle intents
Start activities
Make phone calls
Send text messages
Scan bar codes
Poll location and sensor data
Use text-to-speech
And more
Scripts can be run interactively in a terminal, started as a long running service, or started via Locale. Python, Lua and BeanShell are currently supported, and we're planning to add Ruby and JavaScript support, as well.
