Managing applications

Application manager

The JVM on BlackBerry® devices includes an application manager that functions as the central dispatcher of

operating system events for other Java™ applications.

The net.rim.device.api.system.ApplicationManager class lets applications interact with the application

manager to perform the following actions:

• interact with processes, such as retrieving the IDs for foreground applications

• post global events to the system

• run an application immediately or at a specific time
