Android-IA tracks Mesa master branch and is being rebased once a week 
(so currently at 17.3.0-devel). Plan is to support any new Android release.

Not sure what your goals or requirements are here but have a peek in 
configure.ac to see what options are available. My suggestion is that 
you pull Mesa git and compile/use that instead of the rather old version 
of Mesa in Ubuntu 16.04 (12.x?).
