Phone screen customization

You can customize the phone screens on a BlackBerry® device to display content about a caller by using the PhoneScreen

class that is provided in the net.rim.blackberry.api.phone.phonegui package. For example, you can display content

that is provided by your CRM application about a customer.

The device displays the content on the lower part of the phone screen. If the device has multiple applications that can provide

information about a caller, the device displays content from an application for approximately two seconds before displaying

content from the next application.

To download a sample application that demonstrates phone screen customization, visit www.blackberry.com/go/

phonescreensample. For more information, see the BlackBerry Java Development Environment Integration Development

Guide and the API reference for the BlackBerry® Java® Development Environment.
