Using the emulator

Using the emulator
The emulator is slow, buggy and just plain sucks for development. I strongly recommend to use a real device. If you absolutely have to, keep in mind that the emulator runs in "ugly but fast" mode by default. If you don't want this, you can trade image quality for speed by calling
gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST);
on the gl context. But it still sucks IMHO.
Emulator and OpenGL ES 2.0
It just doesn't work. Don't bother with it.
