Sunucudan JSON nasıl indirilir?

Question

Bir sunucunun nasıl sorgulanacağını ve yanıtı (JSON veya XML) nasıl indireceğinizi gösteren iyi bir örnek var mı?

Bu hile yapmak gerekir

String JsonResponse = HttpHelper.connect(SERVER_URL); 
JSONObject json=new JSONObject(JsonResponse); 

private static String convertStreamToString(InputStream is) { 
     /* 
     * To convert the InputStream to String we use the BufferedReader.readLine() 
     * method. We iterate until the BufferedReader return null which means 
     * there's no more data to read. Each line will appended to a StringBuilder 
     * and returned as String. 
     */ 
     BufferedReader reader = new BufferedReader(new InputStreamReader(is)); 
     StringBuilder sb = new StringBuilder(); 

     String line = null; 
     try { 
      while ((line = reader.readLine()) != null) { 
       sb.append(line + "\n"); 
      } 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } finally { 
      try { 
       is.close(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
     return sb.toString(); 
    } 
    public static String connect(String url) 
    { 
     HttpClient httpclient = new DefaultHttpClient(); 
     HttpGet httpget = new HttpGet(url); 
     HttpResponse response; 
     try { 
      response = httpclient.execute(httpget); 
      //Log.i(TAG,response.getStatusLine().toString()); 
      HttpEntity entity = response.getEntity(); 
      if (entity != null) { 
       InputStream instream = entity.getContent(); 
       String result= convertStreamToString(instream); 
       instream.close(); 
       return result; 
      } 
     } catch (ClientProtocolException e) { 
     } catch (IOException e) { 
     } 
     return null; 
    }
