It was originally developed by Damon Kohler, and had grown through the contributions of many developers. Hot off the heels of my previous post on getting Python scripting on my Android phone via the Scripting Layer For Android, I wrote my first (silly) Python. SL4A is a very useful scripting environment for Android that lets you use scripts written in Python, Perl, Ruby, Lua, Java (BeanShell), JavaScript (Rhino) and other languages. Python for Android PythonForAndroidr4.apk 3. integrated & extended script layer for android library (sl4a): it lets you drive the android work with python. And Python Part of SL4A has became independent project. SL4A doesnt allow you to do native UI components (buttons, scroll bars, and the like), but it does support WebViews.

It was, however, not an official Google product, even though many of its developers have worked for Google. SL4A is used in Rapid application development or prototype development test script Personally, I prefer to use Python since I am always told myself, go and study Python. Using SL4A (which has already been mentioned by itself in other answers) you can run a full-blown web2py instance (other python web frameworks are likely candidates as well). SL4A was first announced by Google in June 2009, and was originally named 'Android Scripting Environment' (ASE). Scripts can be run interactively in a terminal, or in the background using the Android services architecture. These scripts have access to many of the APIs available to normal Java Android applications, but with a simplified interface. SL4A was designed for developers with its main branch no longer being under active development. 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.
