Java is great on desktops and servers. But what about mobile devices? At first sight there aren't too many options. Of course, there is Android. It uses large portions of the Java class library, but brings its own application model and ui toolkit. On iOS there seems to be no Java at all. So, how can you leverage your Java skills on these platforms? This half day workshop shows you how to do this. I will be discussing a handful of approaches that allow you to implement business logic and user interfaces in Java and execute both on iOS and Android. Bring your laptop and let's do quite a bit of coding.
