I try to write some code to display contactList using contactListService, as what you've done before, I encouterd 2 problems:
1. sometimes the result of :contactListService.getRoot() is empty;
2.When "addContacts","addGroup" is running on UIthread, after the list has been initialized , it will freeze when the listView is clicked or menu is clicked.
I try to write the code as what you've done ,but it seems not working well.
Could you tell me why?
