I am currently playing about with lesson 08 here

http://insanitydesign.com/wp/projects/nehe-android-ports/

I would like to change the background colour from black to white. In order to do this at the start of onDrawFrame() I have called

gl.glClearColor(1.0f, 0.0f, 0.0f, 0.0f);

This does indeed set a white background screen, but also results in nothing else showing up on the screen! Clearly this is therefore an incorrect method, but why, and how do I fix it?!

Many thanks in advance.
