Apache licenced harmony project
This is misleading, if not flat-out wrong. Google and Oracle agreed at trial that the materials copied in dispute were part of the Sun Java SEs (1.4 and 5). That the code was out there under a different licence is irrelevant. Google did not try to claim their use was legit on the basis of Harmony (maybe because that licence didn't suit their purposes, either).
The case was not about the language, which Google was free to use. Again, stipulated by both sides at trial. It concerned only the 37 packages, the rangeCheck function, and the 8 security files.
