Developing, Debugging, and Customizing BlackBerry Applications

Use the BlackBerry Client Object API, BlackBerry Device Application Framework API, as well as native Research in Motion (RIM) APIs to create or customize your device applications.

To learn more about the BlackBerry JDE, BlackBerry Java plug-in for Eclipse, or RIM BlackBerry APIs, go to the BlackBerry Java application development Web site at http://na.blackberry.com/eng/developers/javaappdev/.

Note: Do not modify generated MBO API or Device Application Designer generated code directly. For Device Application Designer Code, use the customization pattern documented in this guide by either adding event handlers or customization classes. For MBO generated code, create a layer on top of the MBOs using patterns native to the mobile operating system development to extend and add functionality.

Building an Object API based Client Application
This example illustrates the basic code requirements for connecting to Unwired Server, updating mobile business object (MBO) data, and synchronizing the device application from a Client Object API based device application.
Adding a Device Application Entry Point
If you are creating a BlackBerry device application from code generated directly from mobile business objects (MBOs), add a main file to the application.
Developing the BlackBerry Device Application
This section provides procedures and compares the differences between creating a BlackBerry Device Application from mobile business object generated code in the BlackBerry JDE versus the Blackberry Eclipse plug-in (eJDE).
Debugging BlackBerry Device Development
Device client and Unwired Server troubleshooting tools for diagnosing RIM® BlackBerry® development problems.
Customizing Device Application Designer Code
After you generate code from your BlackBerry development environment, choosing the Custom Class generation option, go to the folders that contain the custom classes, and modify the code as needed. For example, adding controls to screens, adding widget event code, and so on.
