I am developing new app in OpenGL which should run on iOS and Android devices. I'd like to use OpenGL ES 3. For iOS that's not a problem, since any iPhone newer than the 5 has GLES 3.
But I am not sure how wide-spread GLES 3 is in the Android world or if all new devices support it. How can I determine how much support exists for GLES 3 so I can determine if I should use it or fall back to an older version?
