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
