I've been looking at the Android SDK for about 2 days, I wanted to hard code everything in; but all of the examples I find use as little java as possible, and as much XML as they can.

Is there a reason XML is used so much; other than less work? Is it even possible not to use it at all?

 

As far as I can see they use it extensively to make porting apps to different devices/layouts and languages easier. I've done a few minor programs with it and really only used XML the bare minimum for only the essentials.
