文件未通过Android中的DownloadManager下载

Question

您好我想下载视频文件，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);

     }

在下载管理器中我获得了以下信息

如果我传递简单的网址，例如＆＃34; http://beta-vidizmo.com/hilton.mp4＆＃34;那它工作正常

请尝试这种方式，希望这有助于您解决问题。

file_download("http://songs7.funmaza.in/videos/Issey Kehte Hain Hip Hop 720p - Yo Yo Honey Singh [Funmaza.com].wmv",context);

public void file_download(String url,Context context) {
        url = url.replace(" ","%20");
        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)
                .setTitle("Demo")
                .setDescription("Downloading via Your app name..")
                .setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
                .setDestinationInExternalPublicDir(Environment.getExternalStorageDirectory() + "/MyFolder", "test1.3gp");
        downloadManager.enqueue(request);

    }

最后尝试并错误，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);

已经完成了:)感谢Haresh给你
