  @param adType   * Specifies what kind of ad can be served by this {@link AdUnit}
  from the
  AdSense Content Network. This attribute is optional
  and defaults to the ad
  unit's parent or ancestor's setting if one has been
  set. If no ancestor of
  the ad unit has set {@code adType}, the attribute
  is defaulted to {@link
  AdType#TEXT_AND_IMAGE}.
