title: How to modify android Source code and use that into Android device?
body: <p>First my task is: to permanently remove the Bottom menu from Tables Android 4.0.4, which includes back , home and menu keys. I don't want that, as per my requirement.</p>
  
  <p>I have gone through number of blogs and posts available on internet about "How to modify Android Source code". But none of them is clear about exactly changing the Source code and then use that in device.</p>
  
  <p>I mean i downloaded Android source code using <a href="http://pradeep-ki-duniya.blogspot.in/2013/03/hiding-and-showing-system-barstatus-bar.html" rel="nofollow">Hiding and Showing System Bar(Status Bar + Navigation Bar) in Android Tablets using Android Source Code</a></p>
  
  <p><a href="http://pradeep-ki-duniya.blogspot.in/2013/03/hiding-and-showing-system-barstatus-bar.html" rel="nofollow">1</a>: <a href="http://source.android.com/source/initializing.html" rel="nofollow">http://source.android.com/source/initializing.html</a> and got some idea about changing source from <a href="http://pradeep-ki-duniya.blogspot.in/2013/03/hiding-and-showing-system-barstatus-bar.html" rel="nofollow">here</a></p>
  
  <p>but nothing clear to me. 
  Can anyone point me to the clear blog or video which can help me because its a week of googling and still unable to get it done.</p>
