禁用强制关闭弹出android

-1

我想要处理HttpHostConnectException当用户尝试发送一些数据时没有互联网连接。我不喜欢这样，我RESTClient实现类，我连接到服务器：禁用强制关闭弹出android

catch (HttpHostConnectException e) { 

       client.getConnectionManager().shutdown(); 
       try { 
        throw new NoInternetException(); 
       } catch (NoInternetException e1) { 
        inetError = true; 
        e1.printStackTrace(); 
       } 

       e.printStackTrace(); 
      }

，并在我的活动时，我捕捉到了异常：

catch(NoInternetException e) { 
      this.cancel(true); 
      editor.clear(); 
      editor.commit(); 
      finish(); 
      startActivity(getIntent()); 
      Toast.makeText(LoginActivity.this, "You've lost internet connection. You should try later.",Toast.LENGTH_LONG) 
       .show(); 
      e.printStackTrace(); 
      }

我要处理这个异常，重新启动的电流活动这是用户最后一次使用并显示吐司，如“你没有任何连接”。但是我通过强制关闭按钮弹出异常。我不希望它显示，但要重新加载活动并显示Toast与我的消息。我怎样才能实现这个？

逼近是一种力量接近。您的应用程序基本上收到来自内核的SIGINT信号。你不应该拦截它，而是检查你的代码。 – shkschneider

向我们展示强制关闭错误的Logcat。那么帮助你会更容易。 – YuviDroid

你有很多例外...... NullPointerException，HttpHostConnectException，ConnectException。也许这是实际导致强制关闭的NullPointerException（com.library.UserFunctions.getOrders（UserFunctions.java:71））。 – YuviDroid

你得到强制关闭，因为你可能在运行此HttpConnection的在你的UI线程。这是有问题的，因为它会导致UI挂起和结巴......因此，强制关闭。改为使用AsyncTask。

要验证这一点，请检查logcat中的NetworkActivityOnMainThread异常。 – shkschneider

不，我使用AsyncTask作为连接，至于服务器响应解析... –

只有3个错误有重要线路：

Error parsing data org.json.JSONException: End of input at character 0 of 
10-15 18:48:03.759: W/System.err(5061): java.lang.NullPointerException 
10-15 18:48:03.759: W/System.err(5061):  at com.library.UserFunctions.getOrders(UserFunctions.java:71)

你似乎得到一个空的响应，或者至少不能有螺纹JSON响应。检查UserFunctions第71行，并检查您的AsyncTask是否可以处理非JSON结果而不会崩溃。
