        URLPath = "xxxxx";
        URL url = new URL(URLPath);
        uc = (HttpURLConnection) url.openConnection();
        uc.setReadTimeout(30000);//timeout set
        uc.connect();// connect

        fos = new FileOutputStream(savePath);
        InputStream in = uc.getInputStream();
        byte[] buffer = new byte[1024];
        int Length = 0;
        long FinishedLenth = 0;
        while((Length = in.read(buffer)) > 0) {
            FinishedLenth = FinishedLenth + Length;
            fos.write(buffer, 0, Length);
        }
        in.close();
        uc.disconnect();
        fos.close();
      }

这是我的下载代码。当我下载600mb的小文件时，我遇到了问题
并且没有错误发生。
但是我下载了2G的文件大小，错误发生了。

这是一个错误消息，我谷歌的错误消息。
我找到了解决socket关闭问题的方法。
但是下载大文件时出现错误。
所以我不知道如何解决这个问题。
谢谢所有。

问题可能出在

uc.setReadTimeout(30000);//timeout set

对于较大的文件，您的连接可能会超时，请设置一个大于下载文件所需持续时间的值，或者不要指定。
