The Scripting Layer for Android (abridged as SL4A, and previously named Android Scripting Environment or ASE) is a discontinued library that allows the creation and running of scripts written in various scripting languages directly on
Android devices.
SL4A was designed for developers with its main branch no longer being under active development.
These scripts have access to many of the APIs available to normal Java Android applications, but with a simplified interface. Scripts can be run interactively in a terminal, or in the background using the Android services architecture. Currently supported languages are:

It was originally developed by Damon Kohler, and had grown through the contributions of many developers.
