What lib (or code) does android use to implement opengl?

What lib does android use for 3d game?
What gl version does it support? is it open source? how is it compare to mesa?

I can't get the answer from google...

from what I've gathered, which may or may not be correct - I've been seeing if it were possible to make a Maemo machine run Android apps without rebooting - say, a chroot - and it seems quite difficult due to massive abi differences. A whole 'wine' effort to convert the calls would be needed...

but I would think Android should at least still use glibc? not sure...

Maemo on the other hand seems very traditional Linux like.

I guess, you are asking wrong question. Android does not use any library for 3d game. Android is a system that allows creation of games, as well as all kinds of other applications. It provides set of libraries for doing it. The application developers pick the libraries that are most suitable for their applications. Android also provides OpenGL. Here's documentation http://developer.android.com/guide/topics/graphics/opengl.html

So, study the docs for available libraries and choose those that you want to use.

yeah, my question is obscure, sorry.

What I really want to ask is:

What lib (or code) does android use to implement opengl? How is it?
What gl version does it support?
is it open source?
is it developed from scratch by google or copied from other project?
how is it compare to mesa?

To v_andal:
I viewed that page, this page says something about the gl interface and gl version.
but nothing about the implementation status.

I could be wrong, but I believe Android uses OpenGL ES (for embedded systems):
http://en.wikipedia.org/wiki/OpenGL_ES#OpenGL_ES_2.0_2

Yep. It says so right at the beginning of the page that I gave link to
