Originally called Apollo, Adobe Air was released in beta back in 2007 and has gone from strength to strength ever since. You can build an Adobe Air app using HTML, JavaScript, Flash or ActionScript relatively simply. Basically anyone with even a little knowledge of programming and a little patience can create rich Internet applications.

Below, we present the Adobe AIR Developer’s Toolbox: Resources and Tutorials, a round-up of tutorials, links, references, cheat sheets and showcases that will help you create the next popular app.

What is AIR and How To Get Started?

First things first: Adobe Integrated Runtime (AIR) is a cross-platform runtime environment for building rich Internet applications using Adobe Flash, Adobe Flex, HTML, or Ajax, that can be deployed as a desktop application. The runtime bridges the “classic” user experience within Web-applications and rich, highly sophisticated user experience in modern desktop-applications.

To do so, the runtime complements the browser adding desktop integration, local data access, embedded database, convenient desktop APIs and a cross-operating system compatibility. In other words, Adobe Air makes it possible for web-developers to run rich Internet applcations outside the web browser (similar to Mozilla’s Prism) – on the desktop – and also guarantess cross-compatibility across operating systems. Hence, applications are created using a mixture of JavaScript, HTML, and Flash. The resulting application is delivered to end users in a single package and rendered using the WebKit HTML engine.

The only requirement is that the users of AIR-applications have the AIR runtime engine installed (very much like Adobe Flash users need to have the Flash-plugin installed on their system). In fact, Adobe AIR is becoming more and more popular with over 100 million installations of the engine across the globe and over 470 AIR-applications featured on Adobe AIR Market Place.

Adobe AIR SDK

To get you started, you will need the runtime environment for running AIR applications on your OS (download the latest version of Adobe AIR – you will be asked for the OS you are using). You will also need the Adobe AIR Software Development Kit (SDK) to develop, build and deploy Adobe AIR applications.

This development kit (will provide you with the framework for AIR APIs, a template for the Adobe AIR application install badge, the command-line Adobe AIR Debug Launcher and the command-line Adobe AIR Developer tool. The kits are available for Mac OS X (22.1 Mb), Windows (15.8 Mb) and Linux (18.5 Mb).
