Google decided to change the export behaviour of the Eclipse plugin. Here's a solution: http://www.jpct.net/forum2/index.php/topic,2663.0.html

It that one using/trying to use the new hardware accelerated gl emulation? Try to remove the mGLView.setEGLConfigChooser... part from the code. I just noticed that you are trying to use OpenGL ES 2.0. The emulator doesn't support this. Get a real device, the emulator sucks anyway.
