I wanted to watch the innerparts of the Android framework to understand how their UI widgets
are built. When I explored googles android site I realized that Android releases are not shipped
with source jar files which expected!

After a while I found a fast solution to my problem:

After all I´m not intressed in getting all the source files and participate in the FOSS at the moment
just get the app done…

Google please provid source jar files with each release
