Are you a Java developer and want to develop a mobile app that connects to a secured Java EE back end, but you don’t know where to start? This session is tailored for you. This live coding session, driven by Java and using a familiar development environment, goes step by step through building a complete mobile, hybrid, multiplatform application ready to be distributed on different vendors’ stores, such as the Apple store or Google Play. Starting from scratch, the tutorial takes you through building a simple Java EE application and, from there, scaffolding a mobile web client and turning it into a native app, including Android and iOS. This is an in-depth session in which the attendees will learn concretely, and without using hipster tools, how to enter the mobile world.
