get unrecognized content from httpresponse (how to handle gzipped data)

While using httpClient to retrieve content from a HTTP response, I got a content that I can not recognized and it looked like a bunch of compressed data. I figured that it might be due to the content encoding and the following is a code snippet that I used to solve this issue:

private String gzipIS2String(InputStream is) {
        String result = "";
        String line="";
       
        try {
            GZIPInputStream  gzipIS = new GZIPInputStream(is);
            Reader          decoder    = new InputStreamReader (gzipIS, "UTF-8");
            BufferedReader  buffered   = new BufferedReader    (decoder);
       
            while ((line = buffered.readLine()) != null) {
                result += line;
            }
        }
        catch(IOException e) {
            e.printStackTrace();
        }
        return result;
    }

public String getURL(String url) {
        String result = null;

        try {
            DefaultHttpClient httpClient = new DefaultHttpClient();
            httpClient.getParams().setParameter(CoreProtocolPNames.USER_AGENT, "iTunes-AppleTV/5.1 (3; 8GB; dt:12)");
            HttpGet httpGet = new HttpGet(url);

            HttpResponse httpResponse = httpClient.execute(httpGet);
            HttpEntity httpEntity = httpResponse.getEntity();
            if (httpEntity.getContentEncoding().toString().contains("gzip")) {
                result = gzipIS2String(httpEntity.getContent());
            }
            else {
                result = EntityUtils.toString(httpEntity);
            }
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return result;
    }
