I think I got it working by starting the animator and then setting the currentPlayTime(). The documentation clearly tells (which I just stumbled upon) that if the animation has not been started, the currentPlayTime set using this method will not advance the forward!
Sets the position of the animation to the specified point in time. This time should be between 0 and the total duration of the animation, including any repetition. If the animation has not yet been started, then it will not advance forward after it is set to this time; it will simply set the time to this value and perform any appropriate actions based on that time. If the animation is already running, then setCurrentPlayTime() will set the current playing time to this value and continue playing from that point.
http://developer.android.com/reference/android/animation/ValueAnimator.html#setCurrentPlayTime(long)
private void stopAnimation(){ mCurrentPlayTime = mRotateAntiClockwiseAnimator.getCurrentPlayTime(); mRotateAntiClockwiseAnimator.cancel();}private void startAnimation() { mRotateAntiClockwiseAnimator.start(); mRotateAntiClockwiseAnimator.setCurrentPlayTime(mCurrentPlayTime);}
