It's pretty hard to say without more details. I would start out by
making sure that you have a valid rendering context. Disable your
regular rendering and do a hello world type of rendering such as a
single triangle.

I have an OpenGL app that manipulates it's geometry in screen space to

Android's OpenGL implementation seems to be unhappy with this, and
doesn't draw anything.
The same app, compiled from the same code base, works fine on windows
and on iPhone. If I load the app's projection matrix into GL's matrix,
and multiply it's inverse with the final geometry prior to drawing it
(which is effectively a no-op) it displays correctly.
App is native and OpenGL is 1.x if it matters.
Any ideas why is that so?
