I hope to have time to write about Flash Lite from Adobe, Java Micro Edition (Java™ ME), S60, S40, Mobile games, mobile video, prototype development, multiplatform applications, Python, C++, PHP, Adobe ColdFusion, Adobe Flex, JavaScript, ActionScript, Flash Professional IDE, Eclipse, Carbide C++, NetBeans IDE. Enjoy it!

Hi readers,

I've just released Jarpa source code. You can always use the SVN repository to download the latest code. 

Update: You can also take a look at the Wiki Article.

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.

I'm proud to share a short application snippet of the next Jarpa Framework. Jarpa Framework wants to provide developers with the combined power of Adobe's Flash Lite and Java's programming capabilities.

Jarpa is opening the doors to extend Flash Lite capabilities with the widespread acceptance of Java ME. No Symbian nor Java ME knowledge is required to start. We've been using the same process to develop the lbs feature (store locator) on Anina Dress Up game.

Note that the application is a short preview (beta) and was only tested on N95 and also requires a memory card to copy the resources (swf) to open the application. As soon as possible I'm going to reveal the sources at Google code.  Please, let me know your thoughts and if you are looking to a specific feature to be included.

It’s very exciting for us to be featured on Forum Nokia as a FN Success Story. Check it out at http://www.nokia.com/A4126233

"French supermodel Anina and Brazil’s i2 technologia teamed up to create Anina Dress Up, a fashion-memory game created using Flash Lite from Adobe. It is available for S60 3rd Edition and S40 devices."

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.

Nokia Energy Profiler is a stand-alone test and measurement application for S60 3rd Edition, Feature Pack 1 devices (and onwards). The application allows developers to test and monitor their application’s energy usage in real time in the target device.

The application is available as a SIS package for S60 3rd Edition devices, but measurement works only in S60 3rd Edition, Feature Pack 1 (or newer). Older devices can still view files. 

Nokia Energy Profiler 1.1 has the following views:

• Processor
• RAM Memory
• Network
• Signal Levels
• Energy
• Voltage

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.

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.
