Android ICS HTTP POST

我知道这个问题已被询问了很多次。我也搜索了论坛，但无法找到我正在寻找的答案。Android ICS HTTP POST

该代码适用于许多Android版本，但不适用于3.0或更高版本。 String response_from_server = null;

// Create a new HttpClient and Post Header 
    HttpClient httpclient = new DefaultHttpClient(); 
    HttpPost httppost = new HttpPost(file_n_folder.URL_POST); 

    //Log.d("URL",file_n_folder.URL_POST); 

    try { 

     JSONArray postjson = new JSONArray(); 
     postjson.put(obj); 

     // Post the data: 
     httppost.setHeader("json",obj.toString()); 
     httppost.getParams().setParameter("jsonpost",postjson); 

     // Execute HTTP Post Request 
     HttpResponse response = httpclient.execute(httppost); 

     // for JSON: 
     if(response != null){ 

      InputStream is = response.getEntity().getContent(); 

      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(); 
       } 
      } 
      response_from_server = sb.toString(); 

      //Log.d("RESPONSE FROM SERVER",response_from_server); 

      return response_from_server; 
     } 

    }catch (ClientProtocolException e){ 
     Log.d("EXCEPTION line 94",e.getMessage()); 
    }catch (IOException e){ 
     Log.d("EXCEPTION line 96",e.getMessage()); 
    } 
    return response_from_server;

它总是在httpclient.execute（httppost）上崩溃应用程序;

你们可以请我建议我，什么或如何解决这个问题？
