嗨，我想下载视频文件，下面是我的代码

public void file_download(String uRl) {
      File direct = new File(Constant.FOLDER_PATH);
      try {
       uRl = "http://songs7.funmaza.in/videos/"
         + URLEncoder
           .encode("Issey Kehte Hain Hip Hop 720p - Yo Yo Honey Singh [Funmaza.com].wmv",
             "UTF-8");
      } catch (UnsupportedEncodingException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
      }
      System.out.println("URL For Download == " + uRl);
      if (!direct.exists()) {
       direct.mkdirs();
      }
      DownloadManager mdDownloadManager = (DownloadManager) ((Activity) context)
        .getSystemService(Context.DOWNLOAD_SERVICE);
      DownloadManager.Request request = new DownloadManager.Request(
        Uri.parse(uRl));
      request.setDescription("Downloading via Your app name..");
      request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
      request.setDestinationUri(Uri.fromFile(direct));
      mdDownloadManager.enqueue(request);

     }

在下载管理器中，我得到了以下信息

在此处输入图片说明

如果我通过简单的URL，例如“ http://beta-vidizmo.com/hilton.mp4 ”，则它可以正常工作

终于尝试并出错，我找到了这个解决方案，

    File direct = new File(Constant.FOLDER_PATH);
      uRl = "http://songs7.funmaza.in/videos/Issey Kehte Hain Hip Hop 720p - Yo Yo Honey Singh [Funmaza.com].wmv";
      uRl = uRl.replace(" ", "%20");
      uRl = uRl.replace("[", "%5B");
      uRl = uRl.replace("]", "%5D");
      System.out.println("URL For Download == " + uRl);
      if (!direct.exists()) {
       direct.mkdirs();
      }
      DownloadManager downloadManager = (DownloadManager) ((Activity) context)
        .getSystemService(Context.DOWNLOAD_SERVICE);
      DownloadManager.Request request = new DownloadManager.Request(
        Uri.parse(uRl));
      request.setAllowedNetworkTypes(
        DownloadManager.Request.NETWORK_WIFI
          | DownloadManager.Request.NETWORK_MOBILE)
        .setAllowedOverRoaming(false)
        .setDescription("Downloading via Your app name..")
        .setTitle("Issey Kehte Hain Hip Hop")
        .setNotificationVisibility(
          DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
        .setDestinationInExternalPublicDir("/MoviesAndSongs",
          "test1.mp4");
      downloadManager.enqueue(request);

完成了:)也感谢Haresh
