How to do Android build environment setup?

You can get complete information on this topic http://source.android.com/source/initializing.html. If you will get complete information the above mentioned site, why  I am writing this again here? Because some packages are removed from Ubuntu distribution system, so you may not install all recommended packages easily. If you execute following steps before android environment setup as mentioned in android official side, you may not face any trouble.

sudo add-apt-repository ppa:ferramroberto/linuxfreedomlucid 

sudo apt-get update

sudo apt-get install python-software-properties

sudo add-apt-repository ppa:sun-java-community-team/sun-java6 
  
sudo apt-get update 

Then, continue your environment setup procedure. This procedure working fine with me.

Thanks, Enjoy it...
