Twitter API 1.1 in Adobe AIR Mobile

In one of my previous blog posts on Twitter API in AIR Mobile App, many blog readers had requested for coming up with a tutorial on working with Twitter API 1.1 I have been very lazy on my design/development aspects since quite long but wanted to revive those back. So, to start with my Flex/Flash skills, I thought to come up with a tutorial on using Twitter API 1.1 in an AIR Mobile App.
