An important note for users of Early Access how to uninstall:
  1. stop all emulators and Java ME SDK IDE
  2. stop device-manager. If running on jdk 1.6 click on the icon   in status bar and chose Exit. If running on jdk 1.5 use ps aux | grep device-manager.app and kill the process
  3. remove Early Access rm -rf /Applications/Java_ME_SDK_3.0.app
  4. remove working directory rm -rf /Users/<username>/Library/Application Support/javame-sdk

Merry Christmas and happy New Year

- Your Java ME SDK Team

Screencast: Device Selector

Some time ago I asked you how are you familiar with Device Selector. I'd like to thank everybody who answered the question. We have got lots of interesting information. More than half of participants answered "I don't know what Device Selector is." I didn't expect so high percentage of votes for this option so this is a good chance to say a few words about Device Selector functionality.

Device Selector is a small window in the bottom left corner of Java ME SDK development environment. In general you can use it to set emulator properties or simply run project on different emulators. This screencast shows you Device Selector in action.

Preverify: VERIFIER ERROR

If you are running Java ME SDK 3.0 Early Access for Mac OS X you might experience preverify problem and got VERIFIER ERROR message. To fix it run following command in /Applications/Java_ME_SDK_3.0.app/Contents/Resources/bin path:

lipo preverify -output preverify -extract i386

It leaves only 32-bit version in the preverify file and takes out the 64-bit version.

Usability Study

Last week was very interesting for us. We spent two days in usability lab observing how people use Java ME SDK 3.0 and we collected a lot of useful information from this usability study.

We could see four usability study participants every day. Some of them were professional developers, some of them students with different level of Java ME knowledge. It was a really edifying experience to observe people with varied Java ME skills using a product which they haven't had seen before. Each participant got one and half hour to finish three tasks. The tasks were designed to cover general product functionality as well as specialized features, e.g. sensor emulation. Java ME SDK engineering team did a lot of notes and we are also looking forward to results from the user experience team who organized the study for us. We should get the results next week but we have already started to think how to improve the product usability.

Do you want to know how the usability lab looks like? It consists of two rooms, darkened and well-lid, separated by two-way mirror. It allows people in the darkened room to see into the lighted room but not vice versa. I'm sure you know this kind of room from criminal movies. In our case the rooms are equipped better than on police stations and usability study participants feel there more pleasantly than suspects in police interrogation room. We are also much more friendly than police officers :-)

The participant sits alone in the lighted room and working on usability study tasks. Participants are asked to think aloud to allow observers in the next room to follow their mind. User experience team is recording participant's voice, face and desktop to be able to analyze their work-flow later.

We'd like to thank to all participants for attending Java ME SDK usability study and to user experience team for organizing this study. It was very inspiring for us. Thank you!

Following pictures show participant and observers rooms.

This is what really didn't happen during the usability study ... at least not during our study :-))

What's going on with Mac version?

That's a question we have got a lot of times. It was answered here and in different forums, describing why it take some time to release Mac version so I'm not going to write the reasons again. Today I'm going to show you something behind the scene. We are running Scrum process while developing Java ME SDK. Next two pictures were taken at the end of our latest sprint.

The first pictures shows our office board with table of stories and their tasks. As you can see we finished all tasks.

Taskboard

The second picture is more interesting. It shows burndown chart, which is a is graphical representation of work left to do versus time. The green line represents the ideal burndown. You can see that our progress was under the ideal line. It means that we worked faster and finished our tasks sooner than we expected when planning the sprint. Especially in the beginning the progress was quite rapid so in the middle of the sprint we added a few extra stories and we achieved all of them.

Burn down chart

That's what is happening in our team and hopefully answers the title question. Java ME SDK for Mac is in progress and it goes well ... stay tuned – coming soon to a computer near you!

1 update found

Have you started Java ME SDK 3.0 and see a small icon in the bottom right corner?

Update Notification

It appeared there about a month ago and some of you maybe asked what it means. The icon notifies you about available updates for Java ME SDK. This is a new feature in 3.0 release and allows delivery of updates faster than regular releases.

It is very easy and simple to install new updates, just click on the icon and follow instructions.

This first update contains updates of BD-J libraries from HDcookbook project and a few small fixes in Blu-ray development support. During the updating process you can see a message that plugins are signed but not trusted. You can trust them. This issue is also solved in the update and if you install the update this warning will not appear again in the future for next updates.

M3DD Latin America - the best conference I've ever been to

I'm back from Java Mobile, Media & Embedded Developer Days - Latin America (M3DDLA) and I'm still full of impressions from this conference.

M3DDLA was hosted by Senac University, Faculdade de Tecnologia in Goiânia, Brazil and organized by GoJava, Java community of Goiás (state of Brazil). Java has a very big and very active community in Brazil and I could see it at the conference. A lot of people interested in mobile Java technologies registered and came to M3DDLA. Each session had a big audience and there were a lot of questions at the end of each presentation. It was very nice to see Brazilian passion for Java. I can't help myself I have to say that it was the best conference which I've ever been to!

The success of M3DDLA would not be possible without a great organization. I want to say here once more 'thank you' to Murilo, Raphael, Roger, Terrence, Mauricio, Flavia, Filipe, Marcos, Leonardo and all other who I don't know by their name and who worked hard to prepare this excellent conference. Also thanks to everyone who came to visit it because without your audience M3DDLA would have never succeed!

My special thanks go to Jose Luiz Uzeda de Oliveira, manager of Address West Side Hotel Residence where all conference speakers stayed. He and his team did the best for us to feel there as at home and we really enjoyed it.

Four days in Goiânia wasn't just a conference. It was also learning about Brazil. Now I know much more about Brazil than I knew one week ago. Great part of this learning was tasting Brazilian food and drinks. I still remember the taste of tucunaré, feijoada, brunch, cupuaçu, Guaraná Antarctica, caipirinha :-), etc. I can't also forget the trip to Pirenópolis which our new friends organized for us. It was a really nice day ended by swimming under waterfall. It was my first time in Brazil and I hope not last time because this visit still comes back to my mind. Thank you Murilo, Heloisa, small cute Lara, Raphael, Alice, Filipe, Marcos, Leonardo, Igor for spending your free time with us and making our Brazilian experience!

Muito obrigado!
