Hi Alfredo,

Thank you for the code snippet, works as expected.

Also thank you for the issue related to cancel() method, I will keep that in mind.

Something along the lines of ... Notice the line under "Call it again."

                animation = AnimationScheduler.get().requestAnimationFrame(new
AnimationCallback() {
                        @Override
                        public void execute(double timestamp) {
                                        // Do some stuff here

                                        // Call it again.
                                        AnimationScheduler.get().requestAnimationFrame(this);
                                }
                        }
                });
