2. Run the scene on an Android mobile device

4. Touch the screen and you can see that the device screen refresh rate increases to 120hz, and the animation will suddenly speed up as you can see with your naked eyes

1.编辑任意动画，比如：使用Tween操控节点在屏幕上做动画
2.在Android移动设备上跑起场景
3.观察移动设备的屏幕刷新率，待屏幕刷新率降到60hz
4.触摸一下屏幕，可以看到设备屏幕刷新率增加到120hz，同时肉眼可看到动画会突然加速一下
