On Adobe Blog, Rob Christensen has posted a new vedio Flash session: Developing Well-Behaved Mobile Applications for Adobe AIR, the session was talked by  David Knight and Renaun Erickson. David Knight, a member of the AIR development team; Renaun Erickson, a platform evangelist at Adobe.

Adobe TV channel, wrote that this session will "Learn how to tune your applications to provide an optimal user experience within the performance limitations of a device's hardware and software. We'll share tips and tricks for how to build Android applications powered by Adobe AIR that respond quickly. Discover best practices for how to troubleshoot performance problems such as rendering bottlenecks and occasionally connected networks."

This session covered a number of key topics that are valuable for developers building mobile applications using Adobe AIR including:

1.     How to measure the performance of your application
2.     How to detect performance bottlenecks
3.     How to improve the performance of your apps using techniques like object caching, GPU render mode and cacheAsBitmapMatrix
    

Here is the video session:

Christophe Coenraets has posted a new Flash tutorial: Flex for Android in 90 Minutes, this tutorial will tell you a quick way to get started building Flex applications for Android.

The tutorial will be posted as a DevNet article in a couple of weeks, but I already wanted to make it available here because a number of people have asked for it. It is a based on the hands-on session I delivered at MAX, with additional information and instructions.

Here is a quick outline:

1. Part 1: Creating a Basic Mobile Application
2. Part 2: Using Mobile Item Renderers
3. Part 3: Navigating and Passing Information between Views
4. Part 4: Creating an Action Bar
5. Part 5: Integrating with the Device Capabilities (Dialer, SMS, Email)
6. Part 6: Using a RemoteObject
7. Part 7: Using a Local SQLite Database

Blue_Chi has posted a new Flash tutorial: Reacting to iPhone Status Changes Events, the tutorial will teach you how to react to iPhone status changes by using ActionScript 3.0.

Reacting to status changes on the iPhone is pretty easy as all you have to do is register for the corresponding event using the NativeApplication class. This class can be used directly in any iPhone or AIR application to react to application level events.

Here are the codes fragment:

NativeApplication.nativeApplication.addEventListener(Event.EXITING, onExit);
function onExit(e:Event):void {
    //Code to be executed upon exit.
}

Last time, Elad Elrom had posted a Flash tutorial: Optimize Flash Content and Improving Usability on Mobile Devices part #1, this time he has post the Optimize Flash Content and Improving Usability on Mobile Devices – Part #2, in this part Elad Elrom will be covering best practices, tips, tricks, and other useful information to help you create optimized Flash applications for mobile devices.

It includes:

• Architecting
• Manipulating swf Framerate for Optimization
• Reducing memory usage and avoiding memory leaks
• Updating screen once per frame
• Reducing complexity and decreasing nesting
• Avoiding expensive operations
• Decreasing execution time
• Avoiding initializing and reference to unused classes
• Setting redraw region to min
• Reducing swf file size
• Splitting applications into modules
• Reusing objects – Object pooling
• Working with external assets

Renaun Erickson has posted a new Flash tutorial: Debugging AIR apps on iDevices with Flash Builder 4 or Burrito, the tutorial will teach you how to debug your AIR applications running on a iDevice (iPhone, iPod, iPad). The process is very similar to the steps you needed for AIR for Android with Flash Builder 4.

There are the steps:

1. Connect iDevice to the same network as desktop with Flash Builder, and lookup the desktop ip address.
2. Compile application for debugging, both mxmlc -debug and pfi -package -target ipa-debug.
3. Put the debug version of the application on the iDevice device.
4. Configure the project in Flash Builder to launch debugger with out launching the Application.
5. Launch newly configured project.
6. Launch AIR application on the iDevice device.
7. (depends if you use correct value in -connect with adt) Enter IP of Flash Builder machine and click button.
