I SWITCHED MY APP FROM SUPPORT V4 TO APPCOMPAT V7。现在我收到以下错误

我正在通过 XML 从我的服务器下载 IMMAGE.JPG。并在列表视图中显示图像

@Override
    protected Void doInBackground(Void... arg0) {
        //Download the file
        try {
            Downloader.DownloadFromUrl("http://www.atlantisipad.it/atlantis.ipad/AtlantisAndroid.xml", openFileOutput("AtlantisSites.xml", Context.MODE_PRIVATE));
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        return null;
    }

这里是下载类

package com.makemyandroidapp.example.atlantissites;

private static String myTag = "AtlantisSites";

//Handler msg that represents we are posting a progress update.

    try {

        URL url = new URL(URL); //URL of the file

        //keep the start time so we can display how long it took to the Log.
        long startTime = System.currentTimeMillis();
        Log.d(myTag, "download begining");

        // Open a connection to that URL.
        URLConnection ucon = url.openConnection();

        // this will be useful so that you can show a tipical 0-100% progress bar
        //int lenghtOfFile = ucon.getContentLength();

        Log.i(myTag, "Opened Connection");

        byte data[] = new byte[1024];
        //long total = 0;
        int count;
        //loop and read the current chunk
        while ((count = bis.read(data)) != -1) {

            //total += count;

            //write this chunk

        }
        //Have to call flush or the  file can get corrupted.
        bos.flush();
        bos.close();

        Log.d(myTag, "download ready in "
                + ((System.currentTimeMillis() - startTime))
                + " milisec");
    } catch (IOException e) {
        Log.d(myTag, "Error: " + e);
    }
  }
 }
