Using XMLVM to port iPhone app to Android?

I'm considering writing an app for both platforms, but the iPhone app must be bug-free and on time, so I want to write 开发者_JS百科it first. I have no experience with either platform.

It would appear to be that applications written for Android in Java can be converted (imperfectly) to Objective C using XMLVM, after which one could fix it up and make it work with a lot less work.

My question is, can it be done the other way around? I don't see a theoretical reason why it can't, but I haven't found anything that suggests that it's been implemented. (Of course, I'm not fixated on XMLVM; if there's a different solution, I'd be happy to use it.)

Looks like it can't be done.

XMLVM converts bytecode (JVM bytecode, .NET bytecode, or Ruby YARV bytecode) to several different languages, including Objective C. It can't convert Objective C source or compiled code.
