4. Place the items from the contact list into an enumeration.
Enumeration enumContact = contactList.items();
int notFinished
5. Create a While loop to iterate through all the items in the enumeration.
while ((enumContact.hasMoreElements())
c = (Contact)enumContact.nextElement();
int[] fieldIds = c.getFields();
int id;
6. Search for the first contact with a valid city and region and display the address information for this contact in the BlackBerry®
Maps.
if (c.countValues(Contact.ADDR) > 0) {
String address[] = c.getStringArray(Contact.ADDR,0);
if ((address[Contact.ADDR_LOCALITY] != null) && (address
[Contact.ADDR_REGION] != null)) {
MapsArguments(c,0));
}
}
}
} catch (PIMException e) {
}
7. If a contact address is not found, display the default map in the BlackBerry Maps.
if © == null) {
Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, new MapsArguments());
}
}
};
