i want to make sqlite data to jsonarray but i get some problem i have write this code to parse from sqlite to arraylist with hasmap and change it to json with it use gson to convert

public ArrayList<HashMap<String, String>> tampil_meja() {
        SQLiteDatabase database = this.getWritableDatabase();
        ArrayList<HashMap<String, String>> arrayListMeja = new ArrayList<HashMap<String, String>>();

        Cursor cursor = database.rawQuery("SELECT * FROM "+ TABLE_MEJA , null);

        if (cursor.moveToFirst()) {
            do {
                HashMap<String, String> hashMapBiodata = new HashMap<String, String>();
                hashMapBiodata.put("id", cursor.getString(0));
                arrayListMeja.add(hashMapBiodata);
            } while (cursor.moveToNext());
        }
        cursor.close();
        return arrayListMeja;
    }

ArrayList<HashMap<String, String>> arrayListPesan = sqLiteHelper.tampil_semua_pesanan();
        userFunction.gson(arrayListPesan);
        Gson gson = new Gson();
        String jsonPesan = gson.toJson(arrayListPesan);
