class LoadContactAsync extends AsyncTask<Void, Void, String> {

    @Override
    protected String doInBackground(Void... params) {
        Cursor people = getContentResolver()
                .query(ContactsContract.Contacts.CONTENT_URI, null, null, null,
                        "UPPER(" + ContactsContract.Contacts.DISPLAY_NAME
                                + ") ASC");

            if ((Integer.parseInt(hasPhone) > 0)) {
                Cursor phones = getContentResolver().query(
