Symbian Delivers PDK 3.0, Java Apps Support
The Symbian Foundation has released Version 3.0 of the Symbian PDK, based on the Symbian 3 operating system.
In a July 7 blog post, Mark Skrebels, release council chair and senior release manager for Symbian, said Symbian PDK 3.0 is "the first PDK (Product Development Kit) based on Symbian 3 since it achieved its Functionally Complete (FC) milestone" on June 16. "The PDK contains a full build of the Symbian 3 platform along with the corresponding source code, giving developers access to the Symbian 3 feature set and providing the community with the means to engage with us on taking Symbian 3 into devices," Skrebels said.
Skrebels said Symbian 3 represents "a major step forward in the Symbian platform, providing a greatly improved user experience, multiple personalized home screens, an exciting and advanced multimedia experience including HDMI [High-Definition Multimedia Interface] support, the introduction of next-generation graphics, better data networking and much, much more!"
He continued, "PDK 3.0.0 is the first release to support a full UI [user interface] ROM executing on ARMv5 platforms." In addition, Symbian "commissioned a great new theme for the S 3 platform called 'Fresh,' which is included for the first time in this PDK," he said. Screenshots of Fresh can be found here.
Also relating to Symbian 3, Jyrki Aarnos, package owner for the Mobile Runtime for Java Applications, and Aleksi Uotila, product manager for JRT within Nokia, talked in a July 8 blog post about "setting Java applications free with JRT" and enabling developers to write Java applications for Symbian 3 devices.
"Recently, Nokia contributed the JRT to the Symbian Foundation and it is available in the latest Symbian 3 PDK. This means that developers can write Java applications for Symbian 3 devices, like the recently announced Nokia N8," Aarnos and Uotila said in the post. "More importantly, the JRT is now open source so the community can modify and add to the JRT implementation under the terms of the Symbian Foundation's EPL [Eclipse Public License] license."
They continued, "JRT also uses an implementation of the open-source eSWT UI API 1.0.3 from the Eclipse eRCP project. The virtual machine has been provided to the Symbian Foundation by IBM under a separate license, allowing it to be used for research and development purposes and for Java application development.
"The JRT contribution consists of 1 million lines of Java and C++ source code for the runtime, application installer and API libraries as well as test cases and documentation. It is designed to be highly portable to other platforms, has a simple native extension mechanism for adding new APIs and provides a firm baseline for introducing MIDP 3 functionality."
