You can but you only need the callback information for knowing when the surface has been created/modified or destroyed. The renderer will get the same callbacks.
The important things are these: Your activity should only be creating one GLSurfaceView in onCreate and releasing it in onDestroy Your activity onPause and onResume must call your GLSurfaceView's onPause and onResume. Ideally, your GLSurfaceView will create your renderer. Your renderer needs to reload everything (textures, vbos, etc) to video memory when the surface has changed. After the surface has changed, when reloading, get all new texture and vertex buffer IDs. Do not use the old ones or you could crash the gl system. If you follow these rules, your app should play nicely with Android. On Sep 22, 11:05 am, Guian <guiandou...@gmail.com> wrote: > thx for your answer.
