  <p>My class is:</p>
  
  <pre><code>public class JSONParser {
  static InputStream is = null;
  static JSONObject jObj = null;
  static String json = "";
  public JSONParser() {
  }
  public JSONObject makeHttpRequest(String url, String method, List&lt;NameValuePair&gt; params)
  {  try
  {
  if(method == "POST")
  {
      DefaultHttpClient httpClient = new DefaultHttpClient();
      HttpPost httpPost = new HttpPost(url);
      httpPost.setEntity(new UrlEncodedFormEntity(params));
      HttpResponse httpResponse = httpClient.execute(httpPost);
      HttpEntity httpEntity = httpResponse.getEntity();
      is = httpEntity.getContent();
  }
  else if(method == "GET"){
   DefaultHttpClient httpClient = new DefaultHttpClient();
      String paramString = URLEncodedUtils.format(params, "utf-8"); url += "?" + paramString;
      HttpGet httpGet = new HttpGet(url);
      HttpResponse httpResponse = httpClient.execute(httpGet);
      HttpEntity httpEntity = httpResponse.getEntity();
      is = httpEntity.getContent();
  }
  }
  catch (UnsupportedEncodingException e) {
  e.printStackTrace();
  }
  catch (ClientProtocolException e) {
  e.printStackTrace();
  }
  catch (IOException e) {
  e.printStackTrace();
  }
  try { BufferedReader reader = new BufferedReader(new InputStreamReader( is, "iso-8859-1"), 8);
      StringBuilder sb = new StringBuilder();
      String line = null;
      while ((line = reader.readLine()) != null)
      { sb.append(line + "\n");
      }
      is.close(); json = sb.toString();
  }
  catch (Exception e) {
      Log.e("Buffer Error", "Error converting result " + e.toString()); }
       try {
           jObj = new JSONObject(json);
       }
       catch (JSONException e) {
           Log.e("JSON Parser", "Error parsing data " + e.toString());
       }
  return jObj;
  }
  }
