FN Tech Days 2008: Code Camp Competition winner uses Flyer Framework

2008-06-23T18:11:40+03:00

~~Arkanoid~~ Flashbricks from Luis Valente and Jackson Feijó Filho of Rio de Janeiro and Manaus, Brazil. The Nokia Champions created a Arkanoid based game controlled by using "accelerometer". In only three hours Valente and Feijó were able to work on all game logic and connect Python and Flash Lite by using Flyer Framework!

They won a Nokia N95 8 GB! The source code will be published very soon! I and Luciano were there helping with the contest organization =D

Creating scalable QRCodes (swf) with PyS60

2008-05-25T02:36:34+03:00

I'm releasing a short code snippet to create scalable two-dimensional bar code (swf) with Python for S60.

Unfortunately the generated SWF doesn't work on the native Flash player. I'm already trying to fix this strange behaviour but if you get it running please let me know. You can use the Barcode application on the N95 to decode the following picture.

Creating Mobile Videos Article

2008-05-09T14:00:18+03:00

Just published at Forum Nokia an interesting article: Creating Mobile Videos.

This article provides an introduction to the video capabilities of Nokia mobile devices and guidelines for creating and publishing mobile videos. It offers hands-on recommendations for practical issues, such as conversion settings and tool recommendations, as well as a step-by-step walkthrough of an example case where a video clip is adapted for mobile use. In particular, this article is aimed at media content producers who want to ensure reaching the maximum audience with relatively minimum effort.

Developing Flash Lite applications with dynamic layouts

2008-05-06T14:05:46+03:00

Hi readers,

I've just found an interesting article at Adobe devnet: Developing Flash Lite applications with dynamic layouts. It's written by David Brown Lead Developer of Emerging Technology at Agencynet.

"In this tutorial I describe the process I used to develop the dynamic layout of the Bacardi® Mobile Cocktail application. I'll cover how to react to environment changes, such as the current time of day, and how to implement automatic Stage size and orientation switching. Automatic adjustment is especially important for devices such as the Nokia N95, because it is capable of changing its resolution. For other devices, you will learn how to manually alter the orientation of your application to mimic that functionality. " - David Brown

It's a really great user experience made in Flash Lite. There's also a promotional video, check it out: Bacardi Mobile Demo.

Flyer For Maemo: Flex Security Demystified

2008-05-02T16:38:39+03:00

Hello readers,

It's my first time blogging at Forum Nokia Blogs. I am very grateful for use this tool to share my experiments and get in touch with Nokia community.

Seven years ago I started developing Flash content for web and cd-rom but along the evolution of the Flash technology I went to the world of mobile devices. Long short story... Luck of mine!

Last month I received a N810 from Forum Nokia for testing purposes. I really enjoyed to play chess and start the porting of Flyer Framework.

Flyer Framework is an open source project to extend browsing features and mobile technologies. Flyer was primarily built to extend mobile technologies features, especially Flash Lite but along the development We’ve discovered the truly power of the platform.

Flyer Framework runs on almost any OS (Symbian, Linux, Windows, Mac OS) that supports both Flash Player and Python.

While I was working in the porting process of the Flyer engine for Maemo I found an interesting challenge... overcome the flash player security allowing calls between a local python server (flyer engine) and the flash player (web content).

Like Flash Lite 3, the Flash Player plugin embedded on Maemo has built-in security restrictions that prevents cross-domain access. If you are planning to implement and use your own socket server or if you are accessing anything remote from a local file, for security, by default Flash Player does not allow an application to access a remote data source from a domain other than the domain from which the application was served. So you have to put a crossdomain.xml file on the server you are accessing.

A crossdomain.xml file is an XML file that provides a way for a server to indicate that its data and documents are available to SWF files served from certain domains, or from all domains. The crossdomain.xml file must be in the web root of the server that the Flex application is contacting.

You can also check out an article on Forum Nokia Wiki explaining how to archieve this: How to create a Socket Server in Python. To get an in-depth overview of the flash player security model, check out the Developer Connection article: Creating more secure SWF web applications.
