的Android发布JSON崩溃

Question

我有一个项目中，IM使用HttpClient的，但它崩溃，

我的JSON是测井精细，

我有互联网的权限，

我测试了我的请求了HTTPClient ，并正在工作，

但我不知道为什么会崩溃？

这里我的代码，

public void empaquetaYmanda() { 

     Log.d("mensa", "empaquetaYmanda copio"); 


     //build my dictionary! 
     Map<String, String> comment = new HashMap<String, String>(); 
     comment.put("resource_uri", "pa que esto"); 
     comment.put("guid", "345"); 
     comment.put("dob", "13-07-1990"); 
     comment.put("address", "23 rue sante"); 
     comment.put("name", "Sakuraba"); 
     comment.put("mobile", "333456888"); 
     comment.put("email", "saku@sa.sss"); 
     comment.put("points", "333999"); 
     comment.put("surname", "Cerezin"); 
     comment.put("devicetoken", "token334455Droid"); 

     Log.d("mensa", "tu dicto :: " + comment); 

     //lo serializo dicto a json 
     String json = new GsonBuilder().create().toJson(comment, Map.class); 

     Log.d("mensa", "tu json :: " + json); 

     postData("http://sasa.com/api/v1/client/", json); //my 

    } 


    public void postData(String uri, String json) { 
     // Create a new HttpClient and Post Header 
     HttpClient httpclient = new DefaultHttpClient(); 

     HttpPost httppost = new HttpPost(uri); 


    // Url Encoding the POST parameters 
      try { 
       Log.d("mensa", "tu Encoding"); 

       httppost.setEntity(new StringEntity(json)); //revisa! 
       //httppost.setHeader("Accept", "application/json"); 
       httppost.setHeader("Content-type", "application/json"); 

      } catch (UnsupportedEncodingException e) { 
       // writing error to Log 
       e.printStackTrace(); 
      } 

      Log.d("mensa", "tu request::"+httppost); 


      // Making HTTP Request 
      try { 
       HttpResponse response = httpclient.execute(httppost); 

       // writing response to log 
       Log.d("Http Response:", response.toString()); 
       Log.d("mensa", "tu respuesta ::"+response.toString()); 

      } catch (ClientProtocolException e) { 
       // writing exception to log 
       e.printStackTrace(); 
      } catch (IOException e) { 
       // writing exception to log 
       e.printStackTrace(); 

      } 

    }

Answer 1

您试图在UI线程，这就是为什么它抛出NetWorkOnUIThreadException执行网络操作。尝试将您的网络相关代码保存在单独的线程中并执行它。 更好的解决方案是使用异步任务。

Answer 2

你不能让你的主线程的HTTP请求，你必须做他们的的AsyncTask或线程
