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

AnimatorSet scaleFab1 = new AnimatorSet();  
scaleFab1.playTogether(scaleXAnimator, scaleYAnimator); 

AnimatorSet scaleFab2 = new AnimatorSet();  
scaleFab2.playSequentially(fadeInAnimator, moveUpAnimator); 
scaleFab2.start();

@ Dennis Muguti You have to pass in scaleFab and scaleFab1 in your example to give you this animator set

AnimatorSet scaleFab2 = new AnimatorSet(); scaleFab2.playSequentially(scaleFab, scaleFab1); scaleFab2.start();

i only had to change the last part of your code
