Forum Nokia Contest: Are you the cutest?

Participation

To participate in the code competition, you must create a working code example that utilizes Qt and Qt Mobility APIs. The code can be a traditional end-user functioned application or something that is useful for developers, such as a new framework or a new Mobility API implementation.

Note that Forum Nokia would also choose suitable code examples, applications, frameworks and resources to this contest to be published in source code on www.forum.nokia.com wiki.

Participants can create several examples and each will be eligible for an award. If you submit five applications/frameworks, you have a much better chance of winning than if you submit just one!

Developer Talk At UFPE: How to Build Your Own Smartphone with Symbian OS

The time is running out for the end of the year and I forgot to mention about the First Free Software Conference of the UFPE. There I had the pleasure to meet Wilkens and others great open source advocates.

I also had a chance to talk about Symbian (we have compiled the Symbian^3 kernel there), Qt for S60 and a bit of Maemo. Check out some pictures from the presentation and slides.

Marcel, Thanks man for the opportunity! :)

Symbian C++: How to use Accelerometer on Symbian 5th Edition

I'm publishing this Symbian C++ source code snippet since there is a lot of issues between S60 Platform Services and accelerometer on Flash Lite 3.x. I can describe a few here:

1) The accelerometer sensor data stop working on idle screen;
2) You have to set a high frame rate on the Flash side to get real time sensor data;
3) When connected to a socket server the Flash Lite runtime reduces the frame rate to 1 then like the previous statement we can't get real time sensor data;
4) In the chart example the memory gets full after about 12 minutes, the app crashes and usually shows a phone message: 'Not enough memory to load file'. (Thanks Steven to point it out)

The source code is based on Forum Nokia Wiki articles. Hope this help someone! :)

Flash vs Qt: The next battle?

Both Qt and Flash platform have something in common: a cross-platform runtime environment.

IMHO, Qt could be a Flash killer in the near future.

Adobe introduced Adobe AIR on March, 2007, to provide a cross-platform runtime environment for building rich Internet applications using Adobe Flash, Adobe Flex, HTML, or Ajax, that can be deployed as a desktop application and maybe mobile.

While Adobe AIR developers can benefit of using Adobe Flash, Adobe Flex, HTML, or Ajax skills to build applications that deploy to the desktop, Qt developers benefits from a successful open source framework, with high performance on embedded, mobile and desktop.

There are some rumors of Adobe Air to mobile phones that could bring ActionScript 3.0, the current robust OOP programming language of Flash to mobile phones but the question is: Will Adobe be able to deliver AIR runtime to mobile phones with the same performance achieved by the trolls?

...and...

Will trolls be able to maintain Qt flexible and scalable with so many deliveries (Maemo, Symbian, Windows, ...)?

It's my point of view, please, comment if you have any ideas or feedback about this.

Tum: Twitter client for Maemo and Symbian S60

I do not finished my undergraduate degree yet, I have a long history behind it. People sometime treat me like an idiot. I'm not a dumb or I don't like to study.

Every single day I study what I like, I try to acquire skills informally, talking with experts, observing others, through trial-and-error, maybe I am going to be the next Brazilian president ... kidding ... :)

I've been working in my very spare time in a twitter client for Maemo and Symbian phones. It's called TUM, acronym to Twitter User Magnificent. You can see a video from an old version at this Youtube page.

Please, note that I have changed the name of the project because there is already another Twitter client called QTwitter.

Buscapé Widget: Compare preços direto do seu smartphone Nokia

O Buscapé Widget, um miniaplicativo para os smartphones Nokia N97 e 5800, desenvolvido pela pernambucana i2 tecnologia recebeu destaque recentemente em grandes portais de comunicação. É com muito orgulho que divulgo essa notícia pois é através de muito trabalho, esforço e dedicação que estamos alcançando respeito e niveis mais altos no mercado de aplicações para smartphones.

SÃO PAULO - Num esforço para tornar seu smartphone N97 mais atraente para consumidores brasileiros, a Nokia anunciou uma série de widgets desenvolvidos especificamente para os usuários do Brasil.
Segundo a Nokia, uma parceria entre desenvolvedores da fabricante e de empresas fornecedoras de conteúdo e serviços – como Terra e Buscapé, por exemplo – permitiu a criação dos widgets que podem ser instalados no N97 e, depois, acessados por meio de um único toque sobre a tela do celular, já que os miniaplicativos permitem a criação de atalhos já na tela inicial do smartphone.
Entre os widgets exibidos pela Nokia, estão soluções para buscas no comparador de preços BuscaPé, previsão do tempo fornecida pela Climatempo e conteúdo do portal Terra.

A i2tecnologia é uma empresa participante do Forum Nokia Launchpad.

Interview with Mark Wilcox: Qt for S60, Qt for S60 Mac OS X SDK, Symbian S60 and more!

Last month during a chat with Mark Wilcox, a top mobile developer, we talked a lot about Symbian S60 development. In my point of view some of the topics we talked are very important to all mobile developers and due to this importance I decided to publish this short interview.

Felipe Andrade
Hi Mark. How do you going?

Mark Wilcox
Hi Felipe,  I'm good thanks. How about you?

Felipe Andrade
I'm fine but a bit confused. I would like to know your thoughts regarding Qt. At the current stage Qt for S60 seems promising but are there any efforts to port Qt for iPhone or Android at Nokia? I know, there are some legal problems with iphone yet.

Mark Wilcox
Qt for iPhone would be easy - Mac OS X is already supported (including a Cocoa port) but Apple doesn't allow "runtimes" so at the moment no port is planned.

Android doesn't allow native apps.  There is a native SDK for JNI style coding but it's unclear whether that will be available to 3rd party developers.

No native = no Qt - even though the base platform is Linux.

Nokia is going with Qt all the way, so the GTK+ bits of Maemo will become less important.

Personally I think the interesting area for future app development is in Web/native hybrids (using Qt WebKit on Nokia & other Symbian devices).

Felipe Andrade
and Symbian C++?

Mark Wilcox
For system programming only.  In Symbian^4 Avkon will be removed.

Qt (and Orbit) will be the application framework on all Symbian devices.

Felipe Andrade
so... Qt will support all Symbian APIs, right?

Mark Wilcox
Most.  There is the Qt Mobility project and Qt Mobile extensions. It will still be possible to write hybrid code that accesses the system APIs, like you can with Qt on other platforms now.

Felipe Andrade
Are there any efforts to port Symbian SDK to Mac OS X?

Mark Wilcox
Yes. More specifically to Linux, but Mac OS X should work too as it's basically BSD.

Felipe Andrade
Cool! What do you think about the Nokia market share in the next years?

Mark Wilcox
Market share for Nokia is likely to be quite stable in these tough economic times. They may not have the best UX at the moment, but their touch phones are much cheaper than Android and iPhone devices. Nokia also has a good position with Qwerty devices.

Felipe Andrade
Mark, can I publish our conversation in my blog? I think it could be useful for others user and developers.

Mark Wilcox
Also, if you need links to the info on Qt replacing Avkon, there is public info on this on the developer.symbian.org wiki.Search for Direct UI.

Felipe Andrade
Thank you very much for your time and patience!

Mark Wilcox
You're welcome.

Felipe Andrade
Bye for now.

Mark Wilcox
Bye.

WRT Widgets: Loading Google Maps JavaScript API at Runtime

Dear Reader, I wrote another article on Forum Nokia Wiki focused on web runtime widgets. This time I talked about How to Load external JavaScript files at Runtime to reduce application startup time and improve the application performance.

You may have many others benefits by using it:

  • reduce application startup time;
  • minimize data traffic;
  • improve the user experience when it comes to mobile data traffic expenses;
  • improve the user experience inducing flow;

This week's featured article, Using built-in GPS and JavaScript to display your current position on Google Maps, is created by Felipe Andrade (me) :P
