with read_contacts permission in manifest, can synced contacts given business relationship type. whatsapp it's "com.whatsapp". so:

cursor c = getcontentresolver().query( rawcontacts.content_uri, new string[] { rawcontacts.contact_id, rawcontacts.display_name_primary }, rawcontacts.account_type + "= ?", new string[] { "com.whatsapp" }, null); arraylist<string> mywhatsappcontacts = 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. mywhatsappcontacts.add(c.getstring(contactnamecolumn)); }

android contacts whatsapp viber
