    String[] whereArgs1 = new String[]{localContactId};
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null, rawWhere, whereArgs1, null);

    if(cur != null && cur.getCount() > 0) {
        while (cur.moveToNext()) {

                String lookupKey = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
                Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
                cr.delete(uri, null, null);
