AnimationHandler

public class AnimationHandler

This custom handler handles the timing pulse that is shared by all active ValueAnimators. This approach ensures that the setting of animation values will happen on the same thread that animations start on, and that all animations will share the same times for calculating their values, which makes synchronizing animations possible. The handler uses the Choreographer by default for doing periodic callbacks. A custom AnimationFrameCallbackProvider can be set on the handler to provide timing pulse that may be independent of UI frame update. This could be useful in testing.
