Skimmer, which was downloaded over 10,000 times during its first week, is a free desktop application that consolidates social networking activities from Twitter, Facebook, Flickr, YouTube, and Blogger. Using our experiences working on Skimmer we'll let you in on the secrets that will make make developing your own Adobe AIR desktop application much easier. In this session, you'll learn how to handle memory management, decide on a framework, reuse view components from the web, integrate your app with third party APIs, and more. We'll cover both successes and lessons learned during the six months of development on Skimmer.
