我正在开发 Galaxy Note 10.1

下载动作启动java spring 动作。

此下载操作可在 PC、移动设备浏览器中进行

问题是 Galaxy Note 10.1 内置浏览器

这个浏览器的 userAgent 是

“Mozilla/5.0 (Linux; U; Android 4.0.4; ko-kr; SHW-M480W Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) 版本/4.0 Safari/534.30”

而android的下载方式是

mWebView.setDownloadListener(new DownloadListener(){ public void onDownloadStart(String url, String sUserAgent, String contentDisposition, String mimetype, long contentLength) { URL urls = null; String fileUrl = ""; String mPath = ""; Log.v( "sUserAgent", sUserAgent);

            String condition[] = contentDisposition.split("=");
            String x = condition[1];
            Log.d("test",x);
            try {
                fileUrl = URLDecoder.decode(x, "UTF-8");
            } catch(Exception e) {
                e.printStackTrace();
            }
            try {
                urls = new URL(url);
            } catch (MalformedURLException e) {
                e.printStackTrace();
            }
            String fileName[] = url.split("/");
            Log.d("test", url);
            try {
                HttpURLConnection conn= (HttpURLConnection)urls.openConnection();
                conn.setDoOutput(true);
                conn.connect();
                mPath = Environment.getExternalStorageDirectory()+"/Download/";

                String chkPath = Environment.getExternalStorageDirectory()+"/Download/"+fileUrl;
                File chkFile = new File(chkPath);
                if(chkFile.exists() == true){}
                else {
                    File f = new File(mPath);
                    f.mkdirs();
                    File OutputFile = new File(f, fileUrl);
                    FileOutputStream fos = new FileOutputStream(OutputFile);
                    InputStream is = conn.getInputStream();
                    byte[]buffer = new byte[24576];
                    int len1 = 0;

                    while((len1 = is.read(buffer)) != -1) {
                        fos.write(buffer, 0, len1);
                    }
                    fos.close();
                    is.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            Toast.makeText(getApplicationContext(), "DOWNLOAD COMPLETED", 0).show();
            File files = new File(mPath+fileUrl);
            Log.e("msg",mPath+fileUrl+"");
            Intent intent = new Intent(Intent.ACTION_VIEW);
            String mimes = fileUrl.substring(fileUrl.length()-3, fileUrl.length());
            if(mimes.equals("hwp")) {
                intent.setDataAndType(Uri.fromFile(files), "application/x-hwp");
            } else {
                intent.setDataAndType(Uri.fromFile(files), "application/"+mimes);
            }
            startActivity(intent);
        }   
    });

春季下载动作是

字符串 mimetype = "application/x-msdownload";

                response.setContentType(mimetype);
                response.setHeader("fileName", fvo.getFileStreCours()+fvo.getStreFileNm());
                setDisposition(fvo.getOrignlFileNm(), request, response);
                response.setContentLength(fSize);

                BufferedInputStream in = null;
                BufferedOutputStream out = null;

                try {
                    in = new BufferedInputStream(new FileInputStream(uFile));
                    out = new BufferedOutputStream(response.getOutputStream());

                    FileCopyUtils.copy(in, out);
                    out.flush();
                    response.flushBuffer();
                } catch (Exception ex) {
                    // Connection reset by peer: socket write error
                    log.debug("IGNORED: " + ex.getMessage());
                } finally {
                    if (in != null) {
                        try {
                            in.close();
                        } catch (Exception ignore) {
                            log.debug("IGNORED: " + ignore.getMessage());
                        }
                    }
                    if (out != null) {
                        try {
                            out.close();
                        } catch (Exception ignore) {
                            log.debug("IGNORED: " + ignore.getMessage());
                        }
                    }
                }

此文件正在从 NAS 下载

但 android 没有访问 web 的响应缓冲区

在android中，制作了0字节文件。

如何访问 web 响应缓冲区中的缓冲区和下载文件？

附言。网络服务不允许打开网址，所以我不能使用重定向
