Hi,

from my very vague memory of fiddling with android, yes, the Android
itself provides the libs that apps link to, e.g. libGLESv2.so, and
those are trampolines to the real implementations, which is what
you would build from Mesa. Your guess sounds right to me, FWIW.

The last time I looked, a year(?) ago, Android's libEGL multiplexes into
at least two different gfx stacks: Android's own sw-based, and the
vendor's hw stack. You should find the app-facing EGL and GLES libs in
Android's (platform)/frameworks/base/opengl/libs or around there.


Thanks,
