我将文件写入Environment.DIRECTORY_DOWNLOADS，为什么无法通过“下载"应用程序看到它? [英] I write a file to Environment.DIRECTORY_DOWNLOADS, why can't I see it via the Downloads App?

问题描述

我在Environment.DIRECTORY_DOWNLOADS目录中写了一个文件(准确地说，不是下载，而是我的应用程序的SQLite数据库的转储).

I write (write, not download, to be precise it is the dump of a SQLite db of my App) a file on the Environment.DIRECTORY_DOWNLOADS directory.

File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
File file = new File(path, "db.csv");

如果我使用文件浏览器浏览电话，则可以在

If I browse the phone with a file browser, I can see correctly the file in the

  /storage/emulated/0/Download

目录，以及其他下载内容.

Directory, together with the other downloads.

但是，如果我打开下载应用程序，它不会显示...

But if I open the Downloads App it does not show...

要使文件也显示在Downloads App中，我该怎么做?

What do I need to do to have the file shown in the Downloads App as well?

推荐答案

下载"应用仅显示通过DownloadManager下载的下载，而不显示目录中的所有文件.

The Downloads app only shows downloads downloaded via DownloadManager, not all files in the directory.
