I recently updated my tablet to Android 4.0.3 and now the textures for my game do not show up. I'm using OpenGL-ES 2.0 for my engine. It worked fine when I was running android 3.0. Is there any reason as to why this is happening?
It's not terribly well documented, but there are some events which cause an OpenGL context loss on android. Make sure your textures are reloaded after every context loss.
