i try this and work: http://www.androidsnippets.com/gesturedetector-and-gesturedetectorongesturelistener but i need onDoubleTap() it would seem that return super.onSceneTouchEvent(pScene, pSceneTouchEvent); is incorrect i search for good code since yesterday ... — user2080866, Mar 15 '13 at 14:11
i fixed for double tap here http://stackoverflow.com/questions/2640119/how-to-detect-doubletap-on-a-view but but I still can not run surfaceGestureDetector — user2080866, Mar 15 '13 at 14:23

This question is old as i write this reply, but the log message you show above is a not an error message. It is an appropriate message letting you know that the Object Pool for touch events did not contain any touches, so it created more.

This is a normal message from Andengine, and you will see it when you first start using touches, but less as the app runs, because the pool size will grow, and so a touch will be recycled rather than created.
