/**
* Start the animation playing. This version of start() takes a boolean flag that indicates
* whether the animation should play in reverse. The flag is usually false, but may be set to true
* if called from the reverse() method.
*
* <p>The animation started by calling this method will be run on the thread that called this
* method. This thread should have a Looper on it (a runtime exception will be thrown if this is
* not the case). Also, if the animation will animate properties of objects in the view hierarchy,
* then the calling thread should be the UI thread for that view hierarchy.
*
* @param playBackwards Whether the ValueAnimator should start playing in reverse.
