What is Adobe AIR?Adobe Integrated Runtime (AIR) is a

cross-operation system runtime, that allows developers to leverage their

existing Web knowledge skills in HTML, Ajax, XML, Flash and Flex to

build and deploy Rich Internet Application (RIA) on the desktop and

soon on Mobile devices.

Adobe AIR architecture

Adobe AIR 1.5 & Flash 10

3D Effects

The Flash Player 10 3D tool API allows you to

take any pixel or container and

move it around in a 3D space.

Custom Filters & Effects

The Pixel Bender just-in- time (JIT) compiler can also be leveraged and used to process other data, such as sound or logic.

Text Layout Framework

Text Layout Framework (TLF) is Adobe new Flash framework for dealing with text consist of set of classes in Flash Player 10 that brings print-quality to the web and allow you to create multilingual web applications using device fonts.

Enhanced Sound APIDynamic sound generation – the sound APIs allow creating sound dynamically and generate audio applications such as music mixers. You can work with loaded MP3 audio at a lower level by extracting audio data and supplying it to the sound buffer. It allows to process, filter, and mix audio in real time using the Pixel Bender compiler. Speex audio codec – In addition to supporting ADPCM, HE-AAC, MP3, and Nellymoser audio. Flash 10 also support new, high fidelity open source voice codec called Speex (www.speex.org/), which deliver low-latency for voice encoding and adds to the Microphone class.

Visual Performance • Hardware• Acceleration• Vector

Enhance Drawing APIWinding fill - When two shapes used to intercepts we used to have an empty hole. Winding fill means that we have an area fill as long as we have the winding in the same direction.

UV Maps – used in After Effects and other Adobe Video products and allow mapping on a 3D space.

Graphics.drawPath – Uses a list of drawing commands and coordinate to create a pixel.

Graphics.drawTriangles – Take Vector data and renders a set of triangles, typically to distort containers and give them a 3D z dimension.

Reading writing local filesFlash Player 10 has exposed two new APIs in FileReference: load and save.

File I/O API

AIR allows you to access the local file system on the client machine the same as native OS programs. You can do common operations such as reading, writing, moving and renaming.

File.copyTo() vs File.copyToAsync()File.deleteDirectory() vs File.deleteDirectoryAsync()File.deleteFile() vs File.deleteFileAsync()

Local storage and Encrypted SQLite

Adobe AIR 1.5 closed a security gap. All AIR applications are using the exact same database, so essentially any AIR application can read other applications database.

Application Update and Notification API

AIR 1.5 updated the Updater API and assist you updating an existing application. In AIR 1.5 you can actually change the certificate of the application. To update an application the application ID and the publisher ID should match.

Network AwarenessAIR is built to run in conditions where the network connection is changing. There is an event being lunched every time the application connect and disconnect from the internet allowing you to create an application that have network connection awareness.

air.NativeApplication.nativeApplication.addEventListener(air.Event.NETWORK_CHANGE, onNetworkChange);

var socketMonitor:SocketMonitor = new SocketMonitor('www.YourSite.com', 80); socketMonitor.addEventListener(StatusEvent.STATUS, statusChangeEventHandler); socketMonitor.start();

Native Windowing API and Chrom Control

There are three types of windows: Normal - A normal typical windowUtility - A tool paletteLightweight - Lightweight windows with no chrome
