Tizen Developer Summit Korea

Tizen is addressing the need for quality by using a leading edge appscore to identify the best apps to make Tizen a success.  Using an advanced machine learning algorithm, apps created on cross platform tools like Marmalade are identified early and then given the resources (technical and financial) to port the app to Tizen.  It is the first time a true meritocracy has been developed for an app ecosystem.

Mapping and location are essential to any operating system. With HERE, a Nokia business, we aim to deliver the world's freshest maps and location experiences across multiple screens and operating systems. In this session we will demonstrate how HERE supports the Tizen ecosystem and how developers can create location-enabled applications for Tizen with maps and maps-related functionality powered by HERE.

Tizen device have to support local market / country specific service to meet consumer expectation.  In Japanese market, “Ditital TV” support is mandatory to satisfy their requirement as device competition.  However, some specific service functionality is not available / suitable by HTML5 due to some limitation and libraries should be native. In this session, advantage of Tizen platform flexibility comparing to other HTML5 base platform, such as FirefoxOS.

Aki's team optimizes Tizen HTML5 mobile applications at Samsung. While dealing with multiple vendors and several complex apps, they have seen apps which work perfectly, as well as apps with various performance issues.

In this session Aki shares common pitfalls, lessons learned, and proven techniques for achieving good application start-up times and run-time performance.

Accurately measuring HTML5 application performance in Tizen is explained. Aki will then share concrete techniques for improving the measured performance. Topics include tips on correctly initializing complex application structures, efficiently modularizing and lazy loading JavaScript, as well as correctly utilizing smooth hardware-accelerated animations. Aki will also explain techniques how to ensure user-initiated scrolling and animations will work at a steady 60 frames-per-second rate.

The Dynamic Analyzer in Tizen SDK, helps the developers to improve the performance and stability of their application easily. With the following demo, you can find the bottleneck point, unstable usage of memory, file, thread, network, openGL and functions of application and library. Some of them are done by automatically and some are by manually but easily. With the debugger, you must pause the application at a certain point to analyze, and it is still hard to get statistical and analytic information. This tool will resolve these regret, and make yourselves experience wider view of application analysis. For the more, this tool have the potential to add more applicable ideas of analysis. You can contribute to make this tool much better with your ideas and feedback only.

There is a need for web application developer to know how to create compatible applications which work across multiple Tizen devices. Also for application developers, they need a tool to provide guidance during development of Tizen application. On the other hand, App Store needs a tool to provide to assist in screening submitted Tizen applications before acceptance. In this pretension, Xu will introduce Tizen web checker tool and  show how to use this tool to verify the given application package’s validity, API usage, and adherence to security rules in order to avoid violation of API access privileges, using deprecated API, and other compliant issues.
