It is what is said and done in these “moments” that defines our lives. My family is forever blessed that the following people shared moments from their lives with us: Dick and Anne: You both ran the gauntlet with us and we all made it through! We treasure your friendship in ways that words will never be enough. Marcia, my “mom-in-law”: You are always there, and you are always supporting us. We love you deeply. Arthur: At the hardest time, you were there. I will never forget. My deepest thanks I give to my wife and children. I love you, hon. v This page intentionally left blank ContentS Author’s Note ................................................................................................xi Foreword .....................................................................................................xiii Section 1 Setting up Flash CS5 for Android Development .................................................3 Designing and Developing for Android Hardware ......................................7 Configuring the Android SDK Publish Setting ..........................................12 Setting up Flash CS5 for Android Development .......................................15 Installing Your AIR Application onto an Android OS .................................17 Building Your First Application for Android Using Flash CS5 ..................18 Project 1: Creating Your First App Using Flash CS5 .......................................27 Setting up Your Development Environment ..............................................27 Creating the Graphics ..................................................................................35 Building an Application ...............................................................................37 Running Your App on Your Android Phone ................................................43 Section 2 Rapid Android Development in Flash CS5 ........................................................49 Creating Content for Your Android Phone That Does Not Require Programming ..........................................................................49 Animation Techniques You Should Use on Mobile Devices .....................50 Controlling Sound .......................................................................................71 Controlling Video .........................................................................................80 Working in the Third Dimension .................................................................83 What You Have Learned ..............................................................................86 vii viii Contents Project 2: optimizing Animation, Audio, Video, and Component Use in Your AIR for Android Apps.......................................................................89 Your Building Blocks ....................................................................................89 Importing Files into Flash ...........................................................................91 Adding Animation ........................................................................................94 Adding Audio ...............................................................................................96 Adding Video ................................................................................................96 Testing on Your Android Phone ..................................................................96 Section 3 Developing Mobile Apps using ActionScript ................................................101 Enabling Flash to Execute Solutions Faster with AVM 2.0 .....................102 What You Can Expect When You Use AS3 ...............................................102 Controlling Data ..........................................................................................113 Controlling Text ...........................................................................................116 Drawing with the Shape Class ...................................................................117 Using ActionScript to Control Animation, Audio, and Video in Your Android Apps .......................................................................118 Extending Flash with Open Source Libraries ..........................................125 Summary ....................................................................................................125 Project 3: Building Sprite’s 123 ........................................................................127 Setting Up the Project to Run on an iPhone ............................................128 Setting Up the Timeline.............................................................................131 Adding Interaction to Your Number Screens ..........................................134 Completing the Application ......................................................................137 Section 4 Leveraging Custom iPhone and Android Interface Calls with ActionScript ......................................................................................141 Using Gestures in Your Apps ....................................................................142 Working with Gestures ..............................................................................146 Contents ix Which Way Is Up?
