Place Call

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 += "tel:";
                     s+= call.text;
                     navigateToURL(new URLRequest(s));
