Destination: JAR

I'm trying to build my game so that I can play it on my android phone. I thought I might do this by building my game as a Stand-Alone java for mobile devices but every time I try and build it after a while it gives me a "Cannot create destination JAR file" error message. How do I get this to work?

You should wait for the Android exporter that is in development. :)

When can I expect it to be finished? And will it be compatible for Sony Ericsson Xperia Play?

Well?

I can't give you a release date yet, but soon hopefully. Your phone should be compatible.
