I'm trying to create a simple application that renders a background texture using OpenGL ES (I've used the Slideshow example as a basis). The texture (or at least the bitmap) is being successfully loaded, but the output only white.
The texture is 512x512, glGetError returns GL_NO_ERROR after glBindTexture, glVertexPointer, glTexCoordPointer and glDrawArrays.
What is the best way to diagnose the problem?
(As an alternative, I'm willing to dump my entire codebase if there is a better, working, template to work against)
