How to download a video using Uri as path?

[denisnumb]

I am developing an application with Android ≧ 10 target system.

And if I try to get the directory to save the video like this:

File downloadsDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);

This will work, but after clearing the application data or after restarting the smartphone, the application will no longer have access to the downloaded videos.

Because in Android ≧ 10, to work with external files you need to use SAF, that is, Intent.ACTION_OPEN_DOCUMENT_TREE and registerForActivityResult, then as a result I get a Uri as the user-selected path, which I cannot correctly convert into a full path for transmission to YoutubeDL.

How to download a video with only the Uri?

A temporary solution is to download the file to cacheDir and then move it to the desired directory

That's true for clearing the app data or uninstalling the app, but a reboot won't invalidate the file access afaik

to download the file to cacheDir and then move it to the desired directory

Yes, and this is the only way i'm afraid
