Android is a Linux OS kernal plus a  virtual machine  which supports GUI  services  and a JIT compiler in law suites charged by Oracles now. 

A different set of shell tool to write some  AP is not 
a new OS. 

It can be called a new IDE which supports manny services not well maintained by the  free linux 
contributors in a loosely unorganized way.

You can use VMware like techniques to emulate another OS
to support AP of different formats. This is not new at 
all.
