Visual Studio 2017 Studio显示错误``此应用程序处于中断模式''并引发未处理的异常 [英] Visual Studio 2017 studio showing error 'This application is in break mode' and throws unhandled exception

问题描述

我正在开发Xamarin.Android应用.每当我尝试下载JSON feed时，都会出现错误您的应用已进入中断状态，但由于所有线程都在执行外部代码，所以没有可显示的代码" .

I am developing a Xamarin.Android app. Whenever i try to download a JSON feed I get the error "Your app has entered a break state, but there is no code to show because all threads were executing external code".

这是错误的屏幕截图

Here's the screenshot of error

• 我的json提要下载代码

• My json feed download code

 string url = "http://xamdev.epizy.com/getData1.php";

 public async void downloadJsonFeedAsync(String url) {
    var httpClient = new HttpClient();
    Task<string> contentsTask = httpClient.GetStringAsync(url);

    // await! control returns to the caller and the task continues to run on another thread
    string content = await contentsTask;
    Console.Out.WriteLine("Response Body: \r\n {0}", content);

    //Convert string to JSON object
    result = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject> (content);

    //Update listview
    RunOnUiThread (() => {
        listView.Adapter = new CusotmListAdapter(this, result.posts);
        progress.Visibility = ViewStates.Gone;
    });
}

我在这行出现错误

i have got error at this line

字符串内容=等待contentsTask;

string content = await contentsTask;

这是我的json

{ 帖子":[ { "id":"1"， "url":"， "title":在Android应用程序中将语音转换为文本"， "date":"2017-06-16 06:15:18"， "content":将语音转换为Tex，在Android应用程序中将语音转换为文本，在Android应用程序中，在Android Applicationt中转换语音为文本"， 缩略图":"http:\/\/stacktips.com \/wp-content \/uploads \/2017 \/01 \/Speech-to-Text-in-Android-375x300.jpeg" } ] }

{ "posts":[ { "id":"1", "url":"", "title":"Convert Speech to Text in Android Application", "date":"2017-06-16 06:15:18", "content":"Convert Speech to Tex Convert Speech to Text in Android Application Convert Speech to Text in Android Applicationt in Android Application", "thumbnail":"http:\/\/stacktips.com\/wp-content\/uploads\/2017\/01\/Speech-to-Text-in-Android-375x300.jpeg" } ] }

请任何人告诉我我的代码有什么问题吗? 预先感谢..

Please can anybody tell me whats wrong with my code ? Thanks in advance..

这是我的php网络服务代码-

<?php 

if($_SERVER['REQUEST_METHOD']=='GET'){

    require_once('conn.php');

    $sql = "SELECT * FROM space";


    if ($result = mysqli_query($conn, $sql))
     {
      $resultArray = array();
      $tempArray = array();


       while($row = $result->fetch_object())
       {

         $tempArray = $row;
          array_push($resultArray, $tempArray);
      }


    echo json_encode(array("result"=>$resultArray));
    }
        mysqli_close($conn);

     }
   ?>               

推荐答案

最后我得到了答案.

问题出在我的托管服务器上，服务器响应中包含cookie.这就是为什么我的Android应用无法解析json的原因.

Problem was with my hosting server, server response with cookies in it. That's why my android app unable to parse the json.
