Open in Browser

From within your application, you can open a link using the device’s native browser in the same way you can within a traditional browser-based Flex application. This is accomplished with the URLRequest class. Simply creating a new URLRequest and passing this into the navigateToURL method will invoke the user’s browser to handle the request. Figure 6-1 shows the sample application running:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
