Ah sorry for long response time. Anyway, I went back to the problem and started using GLSurfaceView instead and it works with the current setup. With the GLSurfaceView, where am I supposed to implement onTouchListener? Since if I make the "starting" activity to implement the onTouchListener, it never gets called on touch evens.
Any tips what/where it should be implemented? Cheerio for all the tips. On 9 marras, 17:51, Robert Green <[email protected]> wrote: > Ah, I didn't realize how you were initializing GL.
