代码示例来源：origin: googlesamples/android-Camera2Basic

@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());
}

/**
 * Sensor could be rotated in the device, this method returns normal orientation sensor dimension
 */

  int sensorOrientationDegrees = CameraOrientationHelper.getSensorOrientation(characteristics);
  if (sensorOrientationDegrees % 180 == 0) {
    return sensorSize;
  }
  // swap dimensions
  return new Size(sensorSize.getHeight(), sensorSize.getWidth());
