He should have called it "AndroidBootstrap". Since Twitter Bootstrap is a thing that this seems much more closely aligned with.

AndroidBootstrap already exists, then I chose "AndroidKickstartR" ;)

I already created androidbootstrap.com :) different project. :)

What's the difference between this and AndroidBootstrap?

AndroidKickstartR is a dynamic android app generator. It helps to quickly start a project including the libraries you want depending on your needs. Whereas AndroidBootstrap is a more complex and complete template. So, if you don't need some "features" you have to remove the unusable/unused code. So, it really depends on what you need ;)
