setPivotX doesn't work on android 4.1.1 NineOldAndroids

I am animating an ImageView using scaleX(). This is supposed to be a progress bar which fills from left to right. It works without a problem on API 10, 18 and 19. But on API 16 there seems to be a problem with the setPivotX() method. I have tried every option in NineOldAndroids: set view pivot .

final ImageView progressBarFill = (ImageView) getView().findViewById(R.id.progressbarImageFill);
//...

ViewHelper.setPivotX(progressBarFill, 0);
AnimatorProxy.wrap(progressBarFill).setPivotX(0);
animate(progressBarFill).setDuration(1000).scaleX(0.25f);

and

AnimatorSet set = new AnimatorSet();
set.playTogether(
    ObjectAnimator.ofFloat(progressBarFill, "scaleX", 0f, 0.25f)
);
AnimatorProxy.wrap(progressBarFill).setPivotX(0.0f);
ViewHelper.setPivotX(progressBarFill, 0f);
set.setDuration(1000).start();

The animation works but it animates from the center of the ImageView. Can anyone confirm this issue?

UPDATE

I have tried to use androids standard animation package as well: 

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    progressBarFill.setVisibility(View.VISIBLE);
    progressBarFill.setPivotX(0);
    progressBarFill.setPivotY(0);
    AnimatorSet set = new AnimatorSet();
    set.playTogether(
        ObjectAnimator.ofFloat(progressBarFill, "scaleX", 0f, 0.25f)
    );
    set.setDuration(2000).start();
}

But is still doesnt work on android API 16. So the problem is not only related to the NineOldAndroids library but the standard animation function as well.

Turnes out that setting the pivot X to 0 doesnt go down very well in API 16. So to set the pivot to the very left in the view progressBarFill.setPivotX(1);worked a lot better.
