LifecycleAwareAnimationController

A utility for keeping animations within the scope of a given lifecycleOwner.

This is useful in cases where the animation is only valid while the animating view is shown, and the animation end action should be performed immediately is the animating view stops being shown. A concrete example of where this is important, is in a system UI that may play an exit animation for a fragment before actually removing the fragment from the stack. If the animation is interrupted by a call to the containing activity's onSaveInstanceState, the fragment cannot be safely removed anymore by the time that the animation finishes.
