Answer lies in it’s openness and the coming slides too!!

PlatformPlatform Hardware  

Android is not for a single piece of hardware; it's a complete, end-to-end software platform that can be adapted to work on ANY number of hardware configurations.

Everything is there, from the boot loader all the way up to the applications.

Simple!! You may feel it similar to VB
