Version 3.0 of the Symbian Product Development Kit is available, and Symbian 3's Mobile Runtime for Java Applications support enables developers to write Java apps for Symbian devices.
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."
