Huh. I actually was about to suggest that the Java Hello World should work, but a quick perusal dismisses that.
Why would Google bother keeping the JVM class hierarchy if they were implementing a different VM to run against anyway? That just seems to be asking for trouble. I can sort of see some merit to Oracle's argument now. It would be one thing if JVM byte code was treated as an Intermediary representation that then compiled to Dalvik... but it isn't even really that.
Damn, Google stepped in it. Hard.
Edit: Further research indicates Java Byte code is an intermediate representation compiled to Dalvik; so technically the Java Hello World would work coming out in Dalvik (or Android Runtime). So... Back to being confused again, because clearly, even if Google did copy pasta the Java APIs the end machine they are driving is drastically different; I.e., System.out.println() would generate no visible output on Android.
So I'm really back in Google's camp, Oracle is trying to copyright a steering wheel.
"Hello, world" is a rather poor example, because there's little practical value in a mobile application like that. The real value comes from being able to reuse many existing Java libraries.
Hello World! In a Turing space is all you need to implement every other program. Arguments that "there exists no program" come with an inherent verifiability criterion of " well here's one." The thing that Oracle is pissy about is that things get transpired out of Java Byte code, into Dalvik or ART.
Oracle wants patent like protections for the output of Java, and overall API structure in all languages. They want copyright on a meta-pattern. Just trying to imply skulduggery to "look, they joined our API structure, and didn't even do a good job of it, so they should have to pay us for infringement" is a transparent farce. It's an entrenching power grab.
