title: Async HTTP post android
body: <p>I am using an application where i just need to download a pair of coordinates for google maps from a mysql server. I can do this successfully using php and a normal httpost but my app freezes for a few seconds when i do it. </p>
  
  <p>I read that you need to make httppost asycronous in order to avoid that freezing until the server finishes the prossess and sends the results.</p>
  
  <p>The point is that i need that results in a json array like the normal httpost.</p>
  
  <p>For example if i had this httppost.</p>
  
  <pre><code>HttpClient httpclient = new DefaultHttpClient();
  HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");
  
  try {
      // Add your data
      List&lt;NameValuePair&gt; nameValuePairs = new ArrayList&lt;NameValuePair&gt;(2);
      nameValuePairs.add(new BasicNameValuePair("id", "12345"));
      nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
  
      // Execute HTTP Post Request
      HttpResponse response = httpclient.execute(httppost);
  } catch (ClientProtocolException e) {
      // TODO Auto-generated catch block
  } catch (IOException e) {
      // TODO Auto-generated catch block
  }
  
  String result11 = null;
  // convert response to string
  try {
      BufferedReader reader = new BufferedReader(new InputStreamReader(is11, "iso-8859-1"), 8);
      StringBuilder sb = new StringBuilder();
      sb.append(reader.readLine() + "\n");
      String line = "0";
      while ((line = reader.readLine()) != null) {
          sb.append(line + "\n");
      }
      is11.close();
      result11 = sb.toString();
  } catch (Exception e) {
      Log.e("log_tag", "Error converting result " + e.toString());
  }
  
  // parsing data
  try {
      JSONArray jArray1 = new JSONArray(result11);
  } catch (JSONException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
  }
  </code></pre>
  
  <p>How can i convert that to an asynchronous post so i can avoid the freeze ?</p>
