Blimey! Finally Java ME Technology Is Beating Inane Ringtones in the UK
|
It took 7 years, but finally Java ME is the number one revenue generator for mobile content (in UK as measured by total mobile content revenue). MIDP now has a firm foothold in the mobile market that took a while to achieve. This is another good lesson we learned in Java ME tech that applies to the future of both JavaFX Script and JavaFX Mobile.

Juicy Java ME Enabled RAZR 2 is a JUIX Phone But Still EZX in the Core

That should be fine to run a phoneME Advanced stack on top of....Without having to rebuild a new kernel, phoneME Advanced can be built using the OpenEZX header files to link to the EZX or JUIX libs.

A JavaOne Wish List?
Let's proudly represent Java ME Technology at JavaOne this year! There's still time to suggest topics, speakers, sessions, etc. Annette Vernon's blog is calling out for content from the community. We have also created threads on the forums where you can discuss the content that you would like to see related to Java ME Technology as well as open source development in general. Let's Create The Mobile Web Phone
|
If you read my books or my blogs, you will know that I am "pro" web/Open Standards. Thus, this post should not come as a surprise. It's a bit of a gedankenexperiment.
What I am proposing is a mobile phone optimized to accessing information on the Web (which is predominantly browsing but not necessarily so i.e. could include Widgets and RSS).

JIT me up, Scotty
This article talks about how the phoneME Advanced VM (CVM)'s JIT compiled code uses the runtime execution stacks, compiled code flow, as well as tidbits on efficiency and performance issues pertaining to the runtime stacks. Why Desktop Traversal Does Not equal 2D Traversal.
There are many aspects of designing for the consumer mobile space that differ subtly and drastically from the desktop space. Cell phones and desktop pcs evolved for very different usages. Traversal is a great example of one of the places those differences show up so I am going to start with an overview of desktop pc traversal versus phone 2D traversal.

Near-field communications (NFC) is starting to show up more on Java ME technology-enabled cell phones. It is used by having a RFID chip on a cell phone that interacts with the Java ME software to allow cell phone apps to be aware of RFID readers near-by in order for 2-stage authentication to take place.

There's a term that I commonly use to describe CVM: embedded friendliness. Is this really a proper English term? Maybe, or maybe not. But it concisely expresses the idea that a system is suitably designed to work on embedded systems, and thereby has the property of embedded friendliness. —

Access Desktop Data from Mobile Devides
|
Java ME has made it possible to write platform-independent applications for mobile devices and deploy them fairly easily. Now that we have a number of computing platforms strewn all over--office, home, and pocket--we need to think of interconnecting them. As far as desktop devices are concerned, wired internet has provided the necessary linkage for quite some time now.

Java ME tech chosen for Microsoft Windows Live Search Mobile

There is lots of buzz in the Mobile & Embedded community about Microsoft choosing Java ME Technology for their Live Search Mobile application.
Hinkmond Wong notes:
"Notice how the 800-pound gorilla, Microsoft, adheres to the mobile phone app standard and chose to write their Windows Live Search Mobile app in Java ME technology (more).
Meanwhile, Chris Adamson writes that Java ME Technology was simply irresistible for Microsoft to pass up.

Today, I started reading this thread on java.net forums. It made me wonder if people all mean the same thing when they talk about a multi-tasking Java platform. So, I decided to postpone my discussion of CVM internals for a day, and go over the topic of multi-tasking (which is also relevant to phoneME and CVM). —

Background Music in Games - Any Tips
In today's Forums,
Ian Strain has some ME game development advice in the thread
Re: Background Music in Games - Any Tips:
"We looked into this, the only phone we got this working on was the K750, using a midi as the background and wavs for sfx. I'm sure sony ercisson phones in the same category as the K750 will be capable of this too. We tried this on all other devices available (motorola, samsung, sharp, lg, sagem) but it never worked. So, either use a background sound and forget about sfx or just have sfx. I'd go with sfx and anyway most people turn the sound off anyway."
Why it took months to open the source code, and why active development isn't in the open yet. —

With JavaME open-sourced in the phoneME project, the public now has access to the code. However, in order to be able to navigate and effectively contribute to the code, one will also need knowledge of additional details like coding conventions, terminology/jargon, design philosophies, code organization, and design-tradeoff decisions for example. This article will be the first of a series that discusses these topics in addition to technical content about the inner workings of the phoneME Advanced VM. —
