What is Adobe Air?
Adobe AIR is a developer's tool for creating platform-independent web applications. Adobe® AIR® is a multi-operating system, multi-screen runtime that allows you to leverage your web development skills to build and deploy rich Internet applications (RIAs) to the desktop and mobile devices. Desktop, television, and mobile AIR applications can be built with ActionScript 3.0 using Adobe® Flex and Adobe® Flash® (SWF based). Desktop AIR applications can also be built with HTML, JavaScript®, and Ajax (HTML based).
AIR enables you to work in familiar environments, to leverage the tools and approaches you find most comfortable. By supporting Flash, Flex, HTML, JavaScript, and Ajax, you can build the best possible experience that meets your needs.
