SL4A - Scripting Layer for Android -

I read an article from the web on the SL4A (also known as the Android Scripting Environment).

From the site I got an article:

But I only got theoretical knowledge for the SL 4A (ASE) ....

Anyone Practical ideas or practical examples, pls suggest me.

1. What are the scripting languages ​​supported by ASE?
2. How do I download scripts?
3. How do I use scripts?

   By default when you install the scripting environment in which you have shell scripting available (E.g. Bash). Then you can install other languages, currently it supports Python, Perl, Jerubi, Lua, Javascript, BenShell and TCL.
