Creating notifications
Types of notification events
The notification API (net.rim.device.api.notification) lets you add custom events for your application and
define the type of notifications that BlackBerry® device users receive when custom events occur.

Notification event type Description
Immediate events With immediate events, BlackBerry devices notify the BlackBerry device user as soon as the event occurs,
using a system notification, such as a flashing LED, vibration, or tune. An application cannot request a specific
type of notification. In the BlackBerry device profiles list, BlackBerry device users control how they receive
notification of immediate events by choosing an active profile and setting profile options.
Deferred events With deferred events, BlackBerry devices schedule events in a queue according to their priority. When the
event occurs, applications that the event affects can provide custom notifications to the BlackBerry device
user, typically by displaying a UI element, such as a dialog box. The BlackBerry devices do not provide system-
wide notifications for deferred events.
