Java Runtime for S60 with Mobile Sensor API support, finally!
jack44 | 02 April, 2009 19:33
First of all, it's worth noting that Nokia has introduced a new naming scheme for Java platform - "Starting from S60 3rd Edition Feature Pack 2 Java Runtime for S60 is versioned separately from the underlying S60 Platform with aim to provide more frequently new Java versions to the market. Key drivers for that are for example faster time-to-market for new features and a possibility to update Java Runtimes for S60 independently in the future via Nokia SW Update." IMHO, it's a very good decision - the concept is very similar to e.g. Sony Ericsson Java Platform 8 (JP-8) or ealier versions. Currently published versions include Java Runtime 1.3 for S60 (JRT 1.3) and forthcoming Java Runtime 1.4 for S60 (JRT 1.4).
JRT 1.3.x is in use in the Nokia 5800 XpressMusic (sw 20.0.012 onwards) and includes some new features like MIDP security prompting enhancement (a possibility to select the security setting, when the prompt is shown), popup textbox, freely resizable fonts, support for new system property "com.nokia.mid.msisdn" to retrieve the MSISDN, Nokia UI API 1.2, orientation support for Location API (JSR-179) if device has magnetometer hardware, forcing certain orientation by using "Nokia-MIDlet-App-Orientation" JAD attribute, support for downscaling of Canvas graphics.
JRT 1.4.x is in use in the forthcoming Nokia N97. It's very nice to see Mobile Sensor API (JSR-256) support (supports accelerometer, battery charge sensor, charger state sensor, network field intensity sensor). Now you can access sensors natively in Java ME like it's done in C++ (sensor framework) or WRT widgets / Flash Lite (Sensor Service API) and don't need "Multi-Language Programming". The API came to the platform quicker than I expected. JRT 1.4.x includes also Nokia UI API 1.3, 9-way navigation support, 8 Mpix camera support, improved Java support for QWERTY devices, On-Screen Keypad on device with touch screen and hardware keyboard, finger usability improvements for touch screen (tap detection).
The version of JRT can be checked by using standard MIDP system property "microedition.platform". A working sample MIDlet code is available here.

Isn't J2ME dead yet?
Sorcery-ltd | 03/04/2009, 19:37
I keep hearing that J2ME is on its way out, so this is an interesting move in that context.
All the runtimes should be independent of the platform version though, since software upgrading is likely to get much more complex in the future with the Symbian Foundation and the whole concept of a single platform version probably needs re-thinking.

Interesting!
Curious about current JRT support...
jack44 | 09/04/2009, 15:22
I was curious about current JRT support, so I've made some additional tests...
In S60 3rd Ed. FP2 (and newer) there is information about device name, software version, software platform and its version and Java Runtime version, e.g. on my N78 (sw. 11.043) system property returns
"NokiaN78-1/.043/sw_platform=S60;sw_platform_version=3.2;java_build_version=74701". As the screenshot above shows, my 5800XM returns everything right.
In older S60 devices (and Series 40 phones) the returned value is typically something like the following (showing device model and the sw version)... my N95-8GB display "NokiaN95_8GB/15.0.015".
For reference:
S60 3rd Ed. FP2 SDK (v1.1): "Nokia3250/S60_3_2_200802"
S60 5th Ed. SDK (v0.9): "(...);java_build_version=000", but finally S60 5th Ed. SDK (v1.0): "(...);java_build_version=1.3.4"
Hope, this helps!
If you wish, you can post your own results of other S60 3rd Ed. FP2 devices.
What about the N95
jdesbonnet | 28/04/2009, 00:38
Is there any plan to update the N95's Java platform in a future firmware update? It's a great piece of hardware, it's a pity to EOL it so soon.
Re: What about the N95
jack44 | 29/04/2009, 12:04
I wouldn't expect any Java platform updates for N95.
Firstly, it's S60 3rd FP1 device (new naming scheme starts from S60 3rd FP2),
secondly, it's rather old device (in terms of mobile world),
thirdly, there would be a big mess (one person would update the device, the other wouldn't)...

Ah, my friend bought the Nokia5800 Xpress Music. I think the shape and design ia a bit odd, but not really so when I hold the life unit. I just still prefer flip and slider models. classified ads |job listings |bathroom furniture

I'm glad they have sorted this out, I have the Nokia 5800, which I love. I will have to check what version mine is running, and get it updated.
