How to avoid duplicate contact name (data ) while loading contact info to listview?

Question

I am populating contact list details to list view successfully. My code:

  String order = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + \" ASC\";
         


        

Answer 1

Its because the listview is showing both normal contacts as well as whatsapp( or like this) linked contacts. Best is to store all the contacts in a Database and then retrieve the contacts using "select distinct..." command of SQL.
