You can open the contacts application on a BlackBerry® device and display a contact by using the Invoke.invokeApplication() method, and passing in contact data as a parameter of an AddressBookArguments object.

1. Import the required classes and interfaces.

   import net.rim.blackberry.api.invoke.AddressBookArguments;
   import net.rim.blackberry.api.invoke.Invoke;
   import net.rim.blackberry.api.pdap.BlackBerryContact;
   import net.rim.blackberry.api.pdap.BlackBerryContactList;
   import net.rim.device.api.system.ControlledAccessException;
   import javax.microedition.pim.PIM;
   import javax.microedition.pim.PIMException;

2. Invoke PIM.getInstance() to retrieve a PIM instance, and invoke PIM.openPIMList(int, int) to open the default contact list, passing in as parameters the type of list to open (PIM.CONTACT_LIST) and the access mode with which to open the list (PIM.READ_WRITE, PIM.READ_ONLY, or PIM.WRITE_ONLY). To open a named contact list, you can instead invoke PIM.openPIMList(int, int, String).

   BlackBerryContactList contactList = (BlackBerryContactList) 
      PIM.getInstance().openPIMList(PIM.CONTACT_LIST, PIM.READ_WRITE);

3. Invoke BlackBerryContactList.getByUID(String uid) to retrieve a contact from the contact list.

   BlackBerryContact contact = contactList.getByUID("1XKIOD898");

4. Create an instance of the AddressBookArguments class, passing in a Contact object as a parameter.

   AddressBookArguments abArg = new AddressBookArguments("ARG_VIEW", contact);

5. Invoke Invoke.invokeApplication(APP_TYPE_ADDRESSBOOK, AddressBookArguments) and use the AddressBookArguments object for the contact.

   Invoke.invokeApplication(Invoke.APP_TYPE_ADDRESSBOOK, abArg);

6. Check for PIMException, and check for ControlledAccessException if your application does not have permission to access the application that it invokes.
