用于解析JSON的代码在IntelliJ中工作但在android studio中不起作用

Question

网站上发布了一个JSON，我试图阅读并回到Android应用程序通知中。

有问题的JSON字符串： {＆＃34; fridgestatus＆＃34;：＆＃34;失败＆＃34;，＆＃34; fridedetail＆＃34;：[{＆＃34; unit＆＃34;：＆＃34; zxcv＆＃34;，＆＃ 34;姓名＆＃34;：＆＃34; Chill Wall＃2＆＃34;，＆＃34; readtime＆＃34;：＆＃34; 2018-06-05T16：57：00.789000Z＆＃34;，＆＃34; TempF＆＃34;：27.14}，{＆＃34; unit＆＃34;：＆＃34; asdf＆＃34;，＆＃34; name＆＃34;：＆＃34; Chill Wall＃3＆＃34;，＆＃ 34; readtime＆＃34;：＆＃34; 2018-06-05T17：41：08.961000Z＆＃34;，＆＃34; TempF＆＃34;：37.22}，{＆＃34; unit＆＃34;：＆＃34 ; qwer＆＃34;，＆＃34; name＆＃34;：＆＃34; Chill Wall＃1＆＃34;，＆＃34; readtime＆＃34;：＆＃34; 2018-06-05T17：30：50.822000Z＆ ＃34;，＆＃34; TempF＆＃34;：33.98}，{＆＃34; unit＆＃34;：＆＃34; tyui＆＃34;，＆＃34; name＆＃34;：＆＃34; Back Room ＆＃34;，＆＃34; readtime＆＃34;：＆＃34; 2018-06-05T18：34：52.605000Z＆＃34;，＆＃34; TempF＆＃34;：49.46}，{＆＃34; unit＆ ＃34;：＆＃34; ghjk＆＃34;，＆＃34; name＆＃34;：＆＃34; Chill Wall＃5＆＃34;，＆＃34; readtime＆＃34;：＆＃34; 2018-06 -05T18：23：17.123000Z＆＃34;，＆＃34; TempF＆＃34;：36.68}]}

这是托管在某个地址的网址上。

这是我在Java中的代码：

import org.json.JSONArray;
import org.json.JSONObject;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;

public class main {
    public static void main(String[] args) throws Exception{

        String fridge = "All fridges are normal";

            fridge = getFridge();
            System.out.print(fridge);

    }

    public static String getText(String url) throws Exception {
        URL website = new URL(url);
        URLConnection connection = website.openConnection();
        BufferedReader in = new BufferedReader( new InputStreamReader(connection.getInputStream(),"UTF8"));

        StringBuilder response = new StringBuilder();
        String inputLine;

        while ((inputLine = in.readLine()) != null)
            response.append(inputLine);

        in.close();

        return response.toString();
    }

     public static JSONObject parser() throws Exception{


        JSONObject json = new JSONObject(getText("WEB URL"));

        return json;
    }

    public static String getFridge() throws Exception{
        String thisFridge = "No issues.";

        JSONObject json = parser();

        JSONArray n = json.getJSONArray("fridgedetail");
        for (int i=0; i<n.length(); i++){
            JSONObject m = n.getJSONObject(i);
            if(m.getDouble("TempF")>40.00)
                thisFridge = m.getString("name");

        }


        return thisFridge;
    }




}

然而，当我尝试将其拉入android以在临时值过高时发出通知时，应用程序就会崩溃。
