java - 致命自旋挂起/卡在 ThreadID 上

转载作者：搜寻专家更新时间：2023-10-30 21:08:52

我正在为 Android 应用创建自定义日历。它现在的工作方式是从在线 MySQL 数据库中提取事件，将它们传输到 JSONArray 中，然后从那里将它们输入到日历中。它在模拟器上运行良好(如果有点慢)，但今天我连接了我的 S3，它给了我以前没有收到的错误。我在日志中遇到的错误是:

09-14 22:52:12.611: E/dalvikvm(4605): threadid=2: stuck on threadid=1, giving up

09-14 22:52:12.611: E/dalvikvm(4605): 致命的自旋挂起，倾倒线程

这是它一直挂断的 ASyncTask:

package com.legends.app;

import java.io.BufferedReader;

import java.io.InputStreamReader;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;

import android.util.Log;

public class Events extends AsyncTask<Void, Void, String> {

    JSONArray jArray;
    public String result = null;
    InputStream is = null;
    StringBuilder sb=null;
    HttpEntity entity;

    protected String doInBackground(Void... arg0) {

          //http post - calls from the php file that opens the DB
          try{

               HttpClient httpclient = new DefaultHttpClient();
               HttpPost httppost = new HttpPost("http://legendsofnotredame.org/club/mobile/android/cal.php");
               HttpResponse response = httpclient.execute(httppost);

               entity = response.getEntity();

               }catch(Exception e){
                   Log.e("log_tag", "Error in http connection"+e.toString());
              }


          //convert response to string
            try{

                is = entity.getContent();

                BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);

                 sb = new StringBuilder();

                 sb.append(reader.readLine() + "\n");                 

                 String line="0";
                 while ((line = reader.readLine()) != null) {
                                sb.append(line + "\n");
                  }
                  is.close();
                  result=sb.toString();
                  }catch(Exception e){
                        Log.e("log_tag", "Error converting result "+e.toString());
                  }
            Log.e("test","Converted results to string");
            return result;
    }

    protected void onPostExecute(String result) {


    }

}

添加大量日志后，我确定它卡在“sb.append(reader.readLine() + "\n");”上，但我不确定如何让它不执行那。有什么建议吗？

编辑:这是运行它的(几乎)完整的 logcat，从它卡在 readLine 上的地方开始。由于这篇文章太长，我不得不在一开始删除一些非警告/非错误行，抱歉!

这是我在主 Activity 中调用它的地方。这也是两个单独的文件，我不知道这是否相关，但我不知道可能相关。

 Events db = new Events();
        db.execute();
        while (db.result == null){
         continue;}
        result = db.result;

最佳答案

我又玩了一天之后弄明白了。由于非 AsyncTask 中的这些行而超时:

while (db.result == null) {
    continue;
}

它认为这是“你永远陷入了 while 循环，因此程序一定已经崩溃了”，而实际上它只是花时间来阅读事件。但是，如果没有它，它会在没有完全加载事件的情况下继续前进，并在尝试使用该数组时创建 NullPointerException。我所做的是这样做:

while (db.result == null){
   try {
      Thread.sleep(100);
   } catch (InterruptedException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
   }
   continue;
}

sleep 似乎将我还在那里的应用程序发回，只是等待数据以便我可以继续。或者它会减慢我通过 while 循环的次数。不确定它执行哪一个，但无论哪种方式都可以解决问题。
