// Center point is p1; angle returned in radians function findAngle(p0:Point,p1:Point,p2:Point) { var a = Math.pow(p1.x-p0.x,2) + Math.pow(p1.y-p0.y,2), b = Math.pow(p1.x-p2.x,2) + Math.pow(p1.y-p2.y,2), c = Math.pow(p2.x-p0.x,2) + Math.pow(p2.y-p0.y,2); return Math.acos( (a+b-c) / Math.sqrt(4*a*b) ); }

var degrees:Number = radians*180/Math.PI ;

var boolValue:Boolean = (boolString == "true") ? true : false; just one line! I like it!

it’s very easy to make the device stay awake. First you need to enable the following two permissions in the -app.xml file:

<uses-permission android:name="android.permission.WAKE_LOCK">
<uses-permission android:name="android.permission.DISABLE_KEYGUARD">
</uses-permission></uses-permission>

Then you need to use this simple line of code anytime you want to keep the device awake: NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE; To enable the device to go to sleep again: NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.NORMAL;

var req:URLRequest= new URLRequest( "http://translate.google.com/translate_tts ?ie=UTF-8&tl=zh-TW&q=" + encodeURI("中文")); var snd:Sound = new Sound(req); snd.play();
