There was nothing in the lawsuit about being authorised or not. The court ruled that Google's particular use of the Java APIs was not fair use, as it wasn't intended for interop[1]. Apache Harmony can only license what they own, and they don't own the Java API. I guess that if you use Harmony in a way that makes fair use of the APIs you should be fine, but that's not what Google did (at least according to the court's ruling).
