@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public Size(android.util.Size size) {
  this.width = size.getWidth();

@Override
public int compare(Size lhs, Size rhs) {
  // We cast here to ensure the multiplications won't overflow
  return Long.signum((long) lhs.getWidth() * lhs.getHeight() -
      (long) rhs.getWidth() * rhs.getHeight());
}
