You can use the components of the net.rim.device.api.applicationcontrol package to let an BlackBerry® device application display custom messages to a BlackBerry device user when the BlackBerry device application attempts an operation that the BlackBerry device user must permit. The BlackBerry device application displays information about the type of permission that the user must provide. For example, you can use PERMISSION_PHONE for an operation that requires access to the phone functionality of the BlackBerry device.

You can use the applicationcontrol package to include a custom message with the default message that a BlackBerry device application displays in response to an application control.
