Jonathan Schwartz the day before Android SDK became available:

‘I’d also like Sun to be the first platform software company to commit to a complete developer environment around the platform, as we throw Sun’s NetBeans developer platform for mobile devices behind the effort. We’ve obviously done a ton of work to support developers on all Java based platforms, and were pleased to add Google’s Android to the list.’

The Java implementation is a port of JamVM/GNU Classpath. It was first ported back in November last year :

Of course, it isn't "Java" as neither JamVM or GNU Classpath has passed Sun's TCK. But as Sun doesn't make this available to open-source projects it's hardly surprising.

Yes, Sun has announced a new licence for the TCK, but this applies only to implementations substantially derived from Sun's OpenJDK, which neither JamVM or GNU Classpath is.

OpenJDK Community TCK license:

Porting Java to the IPhone was done already, see http://blogs.sun.com/hinkmond/entry/houston_we_have_liftoff but of course it can't be released until they have a legal agreement
