9 ABOUT THE AUTHOR JERMAINE G. ANDERSON has been programming for the past 10 years, specializing in Flash and, more recently, the Flex framework. His work predominantly centers on video streaming, and producing on-demand and live video content for the sports and entertainment industries where he has created web components and rich consumer products using Adobe Flash, Flex, and AIR. In 2004, he became interested in Flash mobile applications; this was intensified after winning the Best Productivity category for his mobile TV guide concept in the first ever Macromedia Flash Lite 1.1 contest in He has since spent time working for UK mobile phone operator T-Mobile, where he created dynamic user interfaces and prototypes using Flash Lite. He has managed an international team of developers and now works for leading entertainment and communications company British Sky Broadcasting. He holds a BSc (Hons) in Chemistry from the University of Birmingham, and an MSc in Computer Studies from Sheffield Hallam University.

10 ACKNOWLEDGMENTS WRITING THIS BOOK WAS TRULY A LABOR OF LOVE during the many days and late nights spent putting it together. Time flew, and before I knew it, the days had turned into weeks, and the weeks had turned into months. The end result is something that I am really proud of. None of this would have been possible without the support of everyone at Wiley, who I d like to give a big thank you! Thank you all for the time and effort spent making things happen. I d like to give special thanks to Scott Meyers, Acquisitions Editor, and Kenyon Brown, Project Editor, for driving the project. Thank you for the belief, guidance, and words of encouragement that were given throughout. Also, thank you to Darren Osadchuk, Technical Editor, for his technical advice and all important feedback. I d also like to thank the development team at Sony Ericsson Velimir Karadzic, Enrique Garcia, and Youness Ghanim who gave some of their time to review and give feedback. Finally, many thanks to all my family and friends, for the love and support they gave me during the time of writing. I couldn t have done it without them, especially my darling wife, Joanna.
