Abstract:

This article complements the online lecture series delivered at the annual Tizen Developer Conference and elsewhere. Titled “JavaScripting Tizen Web Apps” and “Tizen Application Portability,” these lectures serve to guide developers interested in Tizen and the benefits of portable development strategies.

An analysis of the available Tizen APIs begins with consideration of standards and portable web technologies. The Tizen architecture is reviewed, and contrasting its Web and Native Frameworks leads to an inspection of Tizen’s deployment approach and how it affects web logic and content of both server-based and locally installed apps.

While evaluating strategies to leverage JavaScript libraries, a number of popular candidates are presented. Attention is given to the Web Framework embedded version of jQuery Mobile as well as third party alternatives like Sencha Touch, Dojo Mobile, and Enyo JS. Along with a short explanation of native-to-javascript bridges and their potential in portibly employing the Tizen Device API, code samples illustrate the utility of popular JavaScript libraries.

Introducing Tizen:

As far as mobile-optimized operating systems are concerned, Tizen [Tsg01] is certainly a new player. This unique platform enjoying a partnership between Samsung, Intel, and the Linux Foundation intends to soon power a wealth of devices. According to Samsung, “We plan to release new, competitive Tizen devices within this year and will keep expanding the lineup depending on market conditions.” [Busweek01] As the Tizen OS and APIs mature one thing is clear. Tizen architects are putting the concept of portable applications built on standard technologies first and foremost.

In this article we’ll cover the basics of how Tizen APIs support development of portable apps. Regardless of whether the developer uses the official Tizen software development kit (SDK) or other development tools, apps written for Tizen’s Web Framework [Saxena01][Tsg02] can be ported to other platforms leveraging web standards relatively easily. Being an emerging technology Tizen stands to benefit even more from the porting of pre-existing web apps [Wang01].
