问题

我有一个链接，如果我们访问它，.mp4 文件将会自动下载，但如果尝试使用下载管理器下载，则文件将以 .html 格式保存，我想要的是 .mp4 格式。

String ID = "https://presaver.com/download/9Tw-f3i-08k/22";
DownloadManager downloadmanager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri = Uri.parse(ID);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setTitle("YoutubeVideo");
request.setDescription("下载 YouTube 视频");
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setVisibleInDownloadsUi(true);
request.setDestinationUri(Uri.parse(path));
downloadmanager.enqueue(request);

我认为您在这行代码中写错了：

```java
Uri uri = Uri.parse("ID");

应该改为：

Uri uri = Uri.parse(ID); // 字符串 ID

Uri uri = Uri.parse("ID");

Uri uri = Uri.parse(ID); // string ID
