3<p>Provides classes that handle tweened animations.</p>
4<p>Android provides two mechanisms
5    that you can use to create simple animations: <strong>tweened
6        animation</strong>, in which you tell Android to perform a series of simple
7    transformations (position, size, rotation, and so on) to the content of a
8    View; and <strong>frame-by-frame animation</strong>, which loads a series of Drawable resources
9    one after the other. Both animation types can be used in any View object
10    to provide simple rotating timers, activity icons, and other useful UI elements.
11    Tweened animation is handled by this package (android.view.animation); frame-by-frame animation is
12    handled by the {@link android.graphics.drawable.AnimationDrawable} class.
