Android HttpPost崩溃，无法调试？

Question

设备是Xoom平板电脑。出于某种原因，我不能做HttpPost，当我尝试时，我无法捕捉到错误。我尝试了一些基本的例子，它们都以相同的方式崩溃（请参阅堆栈跟踪）。如果我错过了许可，我会附上我的清单。我知道这发生在client.execute(post);声明中。错误没有被捕获，我得到的只是你在下面的堆栈跟踪中看到的内容。我尝试了很多不同的方式，但是我不能告诉我真实的错误是什么。发布数据似乎并不重要，同样的事情发生在一个简单的HttpGet请求。我究竟在想什么？

块有问题

try { 
       HttpClient client = new DefaultHttpClient(); 
       HttpPost post = new HttpPost("http://share1.iqperspective.com/test"); 
       List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); 
       nameValuePairs.add(new BasicNameValuePair("avar", "test data")); 
       post.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
       client.execute(post); 

      }catch (UnsupportedEncodingException e1) { 
       Log.v(TAG, "catch1"); 
      }catch (ClientProtocolException e) { 
       Log.v(TAG, "catch2"); 
      }catch (IOException e) { 
       Log.v(TAG, "catch3"); 
      }

我觉得异常（NetworkOnMainThreadException）的名字告诉你这是怎么回事。您需要在非UI线程上执行您的网络代码。有关更多信息，请参阅文章Painless Threading。
