        String ret = "";
        try {
            InputStream is = getResources().getAssets().open(fileName);
            int len = is.available();
            byte []buffer = new byte[len];
            is.read(buffer);
            ret = EncodingUtils.getString(buffer, "utf-8");
            is.close();
        } catch (Exception e) {
            e.printStackTrace();
