wish help you to fix your issue As suggested by other answer this is a issue reported.
try using :
        ObjectAnimator anim = ObjectAnimator.ofFloat(rowView, "translationY", 0f);
        anim.setInterpolator(new DecelerateInterpolator(1.0f));

android: NullpointerException on startDrag() after animation

Tag : android , By : Jack

I think the issue was by ths following , I had the same problem. You basically need to either cancel() the animation or clearAnimation() from the View, before you will be able to Drag again. You can trigger this cleanup in the AnimationListener's onAnimationEnd(). I went with clearing the animation from the view, because canceling was creating multiple "images" of my view.
Exactly why you need to do this, I don't know.

getting NullPointerException: Attempt to read from field 'int android.view.View.mViewFlags' - Android animation

around this issue As @sasikumar has mentioned the solution was to run the test on real device
but also i solved it on the emulator also by adding postDelayed with 500 milliseconds delay before removing the view in the animation end listener:
animatinSet.setAnimationListener(new Animation.AnimationListener() {
    public void onAnimationStart(Animation animation) {

    public void onAnimationEnd(Animation animation) {
        v_mainContainer.postDelayed(new Runnable() {
            public void run() {
        }, 500);

    public void onAnimationRepeat(Animation animation) {
