DESCRIPTION
Studies report there are more than 100 tools and frameworks for cross-platform mobile development. Most of them are JavaScript/HTML5 based, but are there actually any options for "plain old Java developers" that allow you to write mobile apps for multiple platforms in Java? After a brief overview of the general architectural patterns in cross platform mobile development, we will dig a little deeper and have a look at some Java-based frameworks that claim to make the "write once, run anywhere" promise a reality. In particular, I will demonstrate GWT mobile and Tabris (formerly known as RAP mobile). The session will consist of a few introductory slides outlining the architectural differences between the various options and a lot of live demos of the tools.
