If Google used "Java" to describe Android, Sun would sue them, like they sued Microsoft. "Java" is a trademark and the only way to use it is to pay Sun (well, Oracle now) a lot of money for the compatibility suite.
I don't see how either Harmony or Dalvik should affect Gosling's feelings one way or another. He had no hand in either so deserve no credit. To the extent that Harmony re-implements Java, no-one is trying to deny Gosling credit for creating Java in that context.
The decisions that Google made were either technical (Dalvik is designed with mobile usage in mind while a standard jvm isn't) or contractual (Sun wants control over Java, Google wants control over Android, neither wanted to fold and things are just fine that way: Android is successful in its domain and Java is successful in its domain).
Harmony isn't Google's work. It was an open-source project led by Apache Foundation (http://en.wikipedia.org/wiki/Apache_Harmony) to re-implement Java libraries.
Dalvik was Google's work.
