The URLRequest class can be used to open the Phone application to place a call. By prepending the request with tel:, you will tell Android to launch the Phone application when the navigateToURL method is called. Figure 6-8 shows the sample application running and Figure 6-9 shows the Phone application with the phone number pre-populated:
<s:Application xmlns:fx=”http://ns.adobe.com/mxml/2009″
xmlns:s=”library://ns.adobe.com/flex/spark”>
<fx:Script>
<![CDATA[
protectedfunction sendIt_clickHandler(event:MouseEvent):void
{
var s:String = “”;
s += “tel:”;
s+= call.text;
navigateToURL(new URLRequest(s));
}

</fx:Script>
