java - 将电影文件保存在特定文件夹中 -android-

Question

我有一个用于从 YouTube 下载视频的 Android 代码，它工作正常，但它将视频文件保存在应用程序文件夹中，并且我在“视频”公共(public)文件夹中找不到该视频

public void onNext(String downloadUrl) {
    dismissWaitDialog();

    String fileName = fmtStreamMap.title + "." + fmtStreamMap.extension;
    /*Added By Morad*/
    if (fmtStreamMap.extension.contains("mp3")) {
        Uri uri = Uri.parse(downloadUrl);
        DownloadManager.Request request = new DownloadManager.Request(uri);
        request.setDestinationInExternalFilesDir(MainActivity.this,Environment.DIRECTORY_MUSIC, fileName);
        downloadManager.enqueue(request);
    } else {
        Uri uri = Uri.parse(downloadUrl);
        DownloadManager.Request request = new DownloadManager.Request(uri);
        request.setDestinationInExternalFilesDir(MainActivity.this,DIRECTORY_MOVIES, fileName);
        //request.setDestinationInExternalPublicDir(DIRECTORY_MOVIES, fileName);
        downloadManager.enqueue(request);
    }
}

我使用了 request.setDestinationInExternalPublicDir(DIRECTORY_MOVIES, fileName); 但它不起作用。

  public void onNext(String downloadUrl)
     {
         dismissWaitDialog();

         String fileName = fmtStreamMap.title + "." + fmtStreamMap.extension;

           /*Added By Morad*/

            if (fmtStreamMap.extension.contains("mp3")){
                check_folder(Environment.DIRECTORY_MUSIC);
                Uri uri = Uri.parse(downloadUrl);
                DownloadManager.Request request = new DownloadManager.Request(uri);
                request.setDestinationInExternalFilesDir(MainActivity.this,Environment.DIRECTORY_MUSIC, fileName);
                downloadManager.enqueue(request);
             }else{
                check_folder(Environment.DIRECTORY_MOVIES); 
                Uri uri = Uri.parse(downloadUrl);
                DownloadManager.Request request = new DownloadManager.Request(uri);
                request.setDestinationInExternalFilesDir(MainActivity.this,DIRECTORY_MOVIES, fileName);
                //request.setDestinationInExternalPublicDir(DIRECTORY_MOVIES, fileName);
                downloadManager.enqueue(request);
              }

    }


  public void check_folder(String path)
    {
        File file=new File(path);

        if(!file.exists())
        {
            file.mkdir();
        }
    }
