Hybrid app skills gap is hurting mobile application development

According to Mark Gargenta, CEO at San Francisco-based training company Marakana Inc. and author of the O'Reilly book Learning Android, the future of mobile application development lies in the emergence of the hybrid app, where the tumultuous union of Java code, JavaScript and HTML5 must be counseled and made to work by Android architects and designers.

Hybrid Android applications have certain functions that are going to be coded using HTML5, and other functions that will be programmed natively in Java. The dichotomy of HTML5 versus native apps raises questions as to which parts of an application should be developed using browser-based technologies and which features should be developed using native code. TheServerSide turned to Gargenta for answers.

"For things that are run-of-the-mill," said Gargenta, such as forms or features that you might see on a traditional webpage, there's a good chance Web-based technologies will work. "If there's nothing fancy about the feature you are implementing, you can knock it off using HTML5."

On the other hand, integrating maps or taking and manipulating pictures are the types of activities that can benefit from a native mobile approach. "Those things are best done natively because you can take the power of the mobile device and work with the camera, work with the sensors and create a great user experience," Gargenta said.

The future of mobile application development is a combination of Java, JavaScript and HTML5. Fortunately, there is no shortage of Java developers. Furthermore, programmers who are adept at HTML5 and Web scripting languages are in plentiful supply. But how many developers understand how the two fit together?

When creating hybrid apps melded from Java and HTML5, "there are always technical challenges integrating the two," Gargenta said. "And that is something you can figure out relatively easily, calling Java from JavaScript and vice versa." After all, solving problems through the use of code is what developers do. But architecting a hybrid solution is a different skill altogether, and that's where the current skills gap exists. "Finding the person who can understand everything and architect a full system is more challenging than the technology itself," he said. While the future of mobile development may indeed be a hybrid strategy, widespread adoption of this approach is still a long way off, and one reason for the delay is the lack of skills in integrating Java with HTML5. The hybrid approach will work, but it won't happen until the hybrid app skills gap gets filled, and architects get comfortable and experienced at designing solutions that effectively meld technologies.
