JavaFX Applications Across Devises

Using the new Gluon Mobile framework and some hardware from Adafruit, Gerrit Grunwald describes how to create a mobile/desktop application that can be used to control a mood light that can be turned on and off, set to a particular color, or set to a color cycling mode. His goal in the article "In the Mood: Build Your Own Mood Light and Control It with Java" is to show how easy it is to create a mobile app based on JavaFX.

The Gluon Mobile framework provides methods for achieving platform-dependent settings, which is critical when building an app for different platforms--such as mobile, embedded, and desktop devices--because the UI design is often totally different on different platforms. And, if you are building an Android app, Grundwald points out another advantage of the Gluon Mobile framework: even though Android is not capable of running Java 8, you can use Java 8 in your source code because Gluon Mobile uses retrolambda, which makes it possible to use Java 8 features (except streams) on Java 7.

Grundwald's mood light can be hooked up to the internet and controlled remotely from different devices, such as a mobile phone and a desktop computer. And, if you don't think you need a mood light, he points out another use: you can use it as a build-server status light or for other purposes.

To see how using JavaFX on mobile devices can be a real alternative to native applications--not for all use cases, but at least for some--read the article.

JavaOne Rockstar Speaker Hendrik Ebbers

In a Java Magazine article, senior Java architect Hendrik Ebbers talks about his JavaOne sessions and JavaOne. "There will be some very cool JavaFX, community, open source and Internet of Things talks this year. The talks are always very professional; I have never experienced a bad one. So don't miss the talks" he explains.   

Hendrik focuses on research and development, Swing, JavaFX, middleware and DevOps. He wrote the book titled "Mastering JavaFX 8 Controls" and will present six JavaOne sessions:   
  • Smart UIs for Mobile and Embedded in JavaFX introduces a new JavaFX theme that is made for embedded devices and will fit perfect in all the cool new Internet of Things and mobile products. 
  • DataFX: From External Data to a UI Flow and Back shows how the different DataFX components make it easy to manage external data by using well-known Java technologies.
  • Enterprise JavaFX, an overview of various best practices for communication between server and client, async background tasks, MVC approaches, and the designing of complex dialogue flows
  • Extreme GUI Makeover.  JavaFX 8, a new UI toolkit, offers a lot of amazing features to help you craft modern-looking and interactive UIs.
  • The JavaFX Community and Ecosystem introduces the JavaFX ecosystem including third-party frameworks and popular knowledge base. It also illustrates the functionality and synergy effects between the libraries with a live coding session. 
  • Test-Driven Development with JavaFX
