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! :)

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.

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;

Free WorldWide SMS for Nokia Internet Tablet Users!

Hi All,

It's a long time since my last post. I've been involved  in many activities at i2tecnologia from Adobe Flex to Nokia Web Runtime.
In my spare time I have built a GTK/C version of my proof of concept software. It's called beCloser and has as main focus connect people. This is the first alpha release of the beCloser Marketing tool for Nokia Internet Tablets (N810), for testing purposes only, intended to:

* get more knowledge of maemo development
* engage with open source development
* get feedback from friends and experienced users
* encourage students to start from scratch

My main focus when I started coding beCloser was to connect people around the world with existing mobile technologies. By providing sponsored SMS messages I want to bring mobile communications to a new level.

The beCloser Maemo Edition brings free worldwide sms messages to Nokia Internet Tablets. It's a proof of concept software! Sorry, I can not guarantee that everything is working fine at this time.

* send free worldwide SMS
* easy debian packaging

For N800 users:
Please, please, help me to know if it is working on N800 ;-)
