Finally, create a third set to play the first two sets one after another. The alpha and move animations should go first.

can someone explain to me.

CodeChallenge.java 
ObjectAnimator fadeInAnimator = ObjectAnimator.ofFloat(button, View.ALPHA, 0, 1);
fadeInAnimator.setDuration(1000);

ObjectAnimator moveUpAnimator = ObjectAnimator.ofInt(button, "top", buttonTop, 16);
moveUpAnimator.setDuration(1000);

ObjectAnimator scaleXAnimator = ObjectAnimator.ofFloat(button, "scaleX", 1.0f, 1.5f);
scaleXAnimator.setDuration(300);

ObjectAnimator scaleYAnimator = ObjectAnimator.ofFloat(button, "scaleY", 1.0f, 1.5f);
scaleYAnimator.setDuration(300);

// Add code below!

AnimatorSet fadeAndMove = new AnimatorSet();
fadeAndMove.playTogether(fadeInAnimator , moveUpAnimator);

AnimatorSet scale = new AnimatorSet();
scale.playTogether(scaleYAnimator , scaleXAnimator);

AnimatorSet set = new AnimatorSet();
set.playSequentially(fadeAndMove, scale);
set.start();
