Answer 1

With READ_CONTACTS permission in your manifest, you can get synchronized contacts based on the type of account. For WhatsApp, this is "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()) { // You can also read RawContacts.CONTACT_ID to read the // ContactsContract.Contacts table or any of the other related ones. myWhatsappContacts.add(c.getString(contactNameColumn)); } 

Answer 2

myWhatsappContacts ArrayList will contain all the phone numbers that are present in your whatsapp application.

 Cursor cursor = getContentResolver().query(ContactsContract.Data.CONTENT_URI ,new String[] {ContactsContract.Data._ID ,ContactsContract.Data.DISPLAY_NAME ,ContactsContract.CommonDataKinds.Phone.NUMBER ,ContactsContract.CommonDataKinds.Phone.TYPE} ,ContactsContract.Data.MIMETYPE + "='" + ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE + "' AND " + ContactsContract.RawContacts.ACCOUNT_TYPE + "= ?" ,new String[] { "com.whatsapp" } , null); while (cursor.moveToNext()) { myWhatsappContacts.add(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))); }
