Open the contacts application

You can open the contacts application on the BlackBerry® device by using the Invoke.invokeApplication() method, and passing in the relevant arguments.
  1. Import the required classes and interfaces.
    import net.rim.blackberry.api.invoke.Invoke;
    import net.rim.blackberry.api.invoke.AddressBookArguments;
    import net.rim.device.api.system.ControlledAccessException;
  2. Invoke Invoke.invokeApplication(APP_TYPE_ADDRESSBOOK, AddressBookArguments).
    AddressBookArguments abArg = new AddressBookArguments();
    Invoke.invokeApplication(Invoke.APP_TYPE_ADDRESSBOOK, abArg);
  3. Check for a ControlledAccessException if your application does not have permission to access the application that it invokes.
