(Today we will discuss the implementation of Tween animation in Android development. First of all, it is the same as the Frame animation we discussed in the previous chapter due to the animation method provided by the system. The primary function of Tween Animation is to set the animation track before making animation, including time, orientation, etc. However, the disadvantage of Tween animation is that it can only set two frames of the starting point and the ending point, and the intermediate process is completely ended by the system. Therefore, it is seldom used in game development with a large number of frames.)
