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

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
