I'm in the process of writing an OpenGL ES powered framework for my next Android game(s). Currently I'm supporting three different techniques of drawing sprites:

• the basic way: using vertex arrays (slow)
• using vertex-buffer-objects (VBOs) (faster)
• using the draw_texture extension (fastest, but only for basic sprites, i.e. no transforming)

Vertex arrays are supported in OpenGL ES 1.0 and thus in every Android-device. I'm guessing most (if not all) of the current devices also support VBOs and draw_texture.

Instead of guessing, I'd like to know the extensions supported by different devices. If majority of devices support VBOs, I could simplify my code and focus only on VBOs + draw_texture.

It'd be helpful to know what different devices support, so if you have an Android-device, do report the extensions list please. :)

String extensions = gl.glGetString(GL10.GL_EXTENSIONS);

I've got a HTC Hero, so I can share those extensions next.
