Questions:

I am looking for a very simple tutorial to use OpenGL only for 2D drawing.

My problem is that I want to draw, with OpenGl a bitmap having its pixels.

Thank you in advance,
Ouael

How to&Answers:

The glbuffer for the Android NDK was useful for me.

This answer also has many tutorials linked.

Answer:

Get any 3d example and just set the z coordinate to zero.

e.g. if you have coordinates like (2,3,1) change it to (2,3) or (2,3,0).
