SL4A - Scripting Layer for Android

I read an article from the 开发者_Python百科web on SL4A (which is also known as Android Scripting Environment).

The site from where i got an article is: http://infoworld.com/d/developer-world/php-development-comes-google-android-652

But i got the theorical knowledge only for SL4A (ASE)....

Anybody having practical idea or practical example, pls suggest to me.

1. Which are the scripting language supported by ASE?
2. How do i download script ?
3. How do i use script?

By default when you install the scripting environment you have shell scripting available (like bash). You can then install other languages as well. Currently it supports Python, Perl, JRuby, Lua, Javascript, Beanshell and Tcl.
