                    // TODO Auto-generated method stub

                    List<Animator> animations = new ArrayList<Animator>();
                    animations.add(ObjectAnimator.ofFloat(imgAlpha,
                            View.SCALE_X, 2).setDuration(800));
                    animations.add(ObjectAnimator.ofFloat(imgAlpha,
                            View.SCALE_Y, 2).setDuration(800));
                    final AnimatorSet animatorSet = new AnimatorSet();
                    animatorSet.playTogether(animations);
                    animatorSet.start();
                    animatorSet.setDuration(800);
                    animatorSet.addListener(new AnimatorListener() {

                        @Override
                        public void onAnimationStart(Animator animation) {

                        }

                        @Override
                        public void onAnimationCancel(Animator animation) {

AnimatorSet.end() fires onAnimationEnd(Animator) hence a recursion.

See documentation:

Ends the animation. This causes the animation to assign the end value of the property being animated, then calling the onAnimationEnd(Animator) method on its listeners.
