Finally, create a third set to play the first two sets one after another. The alpha and move animations should go first, followed by the scale animations. Don't forget to start this last set to run everything!

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.playTogether(fadeAndMove, scale);

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