string youraccounttype="";//ex: "com.whatsapp"     cursor c = getcontentresolver().query(             rawcontacts.content_uri,             new string[] { rawcontacts.contact_id, rawcontacts.display_name_primary },             rawcontacts.account_type + "= ?",             new string[] { youraccounttype },             null);      arraylist<string> contactlist = new arraylist<string>();     int contactnamecolumn = c.getcolumnindex(rawcontacts.display_name_primary);     while (c.movetonext())     {         // can read rawcontacts.contact_id read         // contactscontract.contacts table or of other related ones.         contactlist.add(c.getstring(contactnamecolumn));     }     c.close();
