Asha.jpg Nokia has announced a series of new S40 phones called “Asha” – mass-market devices with smart-phone features: Good-sized touch screens, 1 GHz processors, WiFi connectivity, social networking integration, and more. Prices starting around €60 retail.

In case you don’t know, the S40 series is built on Java ME and has a huge deployed base in many parts of the world where price/performance is critical. Along with the new phones, Nokia is also making available the new Nokia SDK 2.0 for Java (beta), which enables developers to build rich Java applications with multi-touch, sensor support, an improved Maps API, and the Lightweight UI Toolkit (LWUIT) (more API & tools details). Furthermore, there is a host of developer information, the remote device access service, and even a porting guide to help you port your Android app to the new Asha platform.

Last, but not least: More and better options to monetize your applications. Nokia has enabled in-app advertising and in-app purchasing, and improved the way applications can be discovered by customers. Nokia has seen downloads from the Nokia app store rise by 63%, now totaling billions.

From what I’m hearing, the revenue opportunities on S40 for developers are often way better than what is typical for other smart-phone platforms (where competition is huge and consumers are fickle).

ojwc-use-cases-small.jpgWith over 3 billion devices and counting, Java on mobile devices is enjoying growth and huge adoption in many key markets around the world.

In the meantime, developers are pushing to build richer and more interesting applications, both from a functional as well as a user interface perspective. New use cases in mCommerce, social networking, location-based services, mobile cloud features, and access to functionality on the operator network are catalysts to create and deliver new compelling applications to the largest mobile user base.

To that end, Oracle is revving the mobile Java platform with Oracle Java Wireless Client 3.1 (OJWC). OJWC is an industry-leading Java ME implementation geared towards device manufacturers, operators, and OEMs who want to get to market quickly with a full-featured, high-performance mobile Java runtime.

This latest 3.1 release provides the following new functionality:

  • SIM Extensions—Enable remote content management on mobile handsets through SIM-based services
  • Oracle Mobile Developer APIs—Allow new use cases for Java ME applications on feature phones
  • Improved Content Management APIs—Facilitate content discovery and deployment
  • Network APIs—Leverage data from operator’s network for running smarter Java ME applications on resource-constrained devices
  • Other Enhancements—Aid integration with the device platforms

Oracle Java Wireless Client 3.1 will become available on devices over time as it is rolled out in markets around the world.

For developers, the new features such as the Oracle Mobile Developer APIs and the Network APIs are of particular interest. You will be able to start building applications for OJWC 3.1 with the upcoming next release of the Java ME SDK – stay tuned for this.

Find out all the details about OWJC here.

Finally, I get a chance to catch my breath. JavaOne has been extremely busy and while there are still a few hours of good talks to go here is a quick summary so far:

General observations:

The vibe is very positive. Attendance is significantly up over previous years and the show is well organized. Feedback from attendees has been very excouraging – lots of good buzz on #javaone and other social channels. Many sessions are sold out or standing-room only.

Announcements:

This year’s JavaOne left no doubt Java is moving again, and picking up steam. Throughout the conference and in the various keynotes there was a host of announcements, strategic initiatives, roadmaps, product releases and updates.

I’ll try to summarize, focusing on the Java Platform, Java SE, and Java ME technologies:

Java SE and the Java Platform:

  • Oracle announces plans for advancing the Java SE Platform, including a vision beyond JDK 8

  • Oracle is continuing its work to merge the HotSpot and JRockit JVMs, with the first converged features available in JDK 7
  • IBM announces availability of Java SE 7 across its products lines, the faster ever adoption of a new Java SE release by IBM
  • Oracle recently announced availability of Java SE 7 for Embedded on ARM and x86 platforms

OpenJDK:

  • OpenJDK hosts the development of JDK 7 for Mac OS X, JDK 8, and becomes the reference implementation for Java SE 8 and beyond
  • Twitter joins OpenJDK

JavaFX and Rich Client UI Technology:

  • The JavaFX 2.0 GA for Windows is now available
  • A JavaFX 2.0 for Mac OS X Developer Preview is now available, with GA releases planned starting 2012
  • NetBeans 7.1 Beta is now available, with JavaFX 2.0 support
  • Oracle details JavaFX roadmap to 2013, including cross-platform support for Mac OS X and Linux
  • Oracle announces plans to open source the JavaFX platform in the OpenJDK project
  • A private Beta for JavaFX Scene Builder is now available, with public Beta planned in early 2012
  • Oracle announces Project ‘Avatar’: A complete solution for Dynamic Rich Clients, including HTML5 support and back-end integration

Java ME:

  • Oracle increases investment in Java ME
  • Oracle Java Wireless Client (OJWC) 3.1 is now available
  • Oracle announces plans to evolve the Java ME Platform and align Java ME with Java SE 7 through:
    • Submission of new JSRs over the coming months
    • Updates of the CLDC Platform VM and library specifications to enable better alignment with Java SE 7 features
    • Creation of a “CDC Profile” in Java SE 8, which allows deployment of Java SE 8 implementations in resource-constrained environments
  • JavaFX to become the graphics framework of choice for mid-range and high-end embedded platforms
  • Oracle announces intent for full coverage of embedded vertical markets
  • Oracle plans increased and deeper integration of Java ME with content services (“Mobile Services Integration”)

Updates:

  • 5/15/2011: Added link to previous blog on Twitter API ME and a How-To (see below)

Smartphones get a lot of attention these days, but feature phones running Java ME outsell smartphones by a 5x-10x margin and have an installed based measured in the billions, not millions.

So, as an application developer or ISV, if you are going for the big markets, Java ME really needs to be part of your platform story. Not only does Java ME provide the big numbers, but Java ME also has all the tools and features to make creating great applications easy – applications that look and feel like smartphone-class applications.

Ok, so, let’s say you want to create one of those cool, new-fangled social networking-/location-based/interactive mash-up applications … Where do you start?

A while ago, I created a presentation and a sample application on just that topic. I presented it first at JavaOne 2010 in San Francisco as session S314178: “Beyond Smartphones: Rich Applications and Services for the Mobile Masses” and you can find the presentation by searching at the JavaOne content catalog.

video-shot.pngI’ve been continuously updating it since, and have now released the source code under the BSD license on java.net. The “Meet Me For Dinner” sample application and project shows the core building blocks and development aspects of creating rich and compelling applications and content for Java ME platforms.

The sample app is not perfect (still has a few minor bugs and is lacking some nice-to-have features) but the goal is to show interested developers how to get started and enables them, due to the liberal BSD license, to copy-and-paste code as a starting point for their own projects.

Check out this short video for an introduction. Then go the “Beyond Smartphones” project on java.net for the full sources, instructions on how to build and run the code, and a forum for questions. Also, see my previous post on the Twitter API ME for more information and a “How-To”.

Finally, if you’re planning to attend JavaOne in Hyderabad, India next week (May 10-11), be sure to attend the “Beyond Smartphones” session scheduled for Wednesday, May 11, at 3:45 pm.

mobile-statistics.jpg Ernandes Mourao Junior is cranking out good stuff. A while ago I blogged about his excellent Twitter API ME project – I’ve used it myself and it works very well.

Among other things he is working on, Ernandes now has released the Google Analytics ME API.

Quote:

Google Analytics ME is a compelling and well defined API for Java ME and Android developers who wish to integrate their apps into Google Analytics. With this API, developers will be able to prepare their apps to send out useful data, about how users are interacting with them. Those data will be valuable to identify, e.g., audience and improvement points.

The project page has a few introductory code snippets, the code itself, as well as links to further documentation on Google Analytics. Looks pretty straightforward – I hope to be able to give this a spin soon.

Thanks, Ernandes – and keep up the good work!

Cheers,

– Terrence
