Affected version

0.24.0

Steps to reproduce the bug

1. Export subscription into a file by clicking export to>file under subscription tab
2. Clear data
3. Try to import the subscription by clicking import from>exported file
4. The file picker won't even let you pick the exported file

Expected behavior

The app should import subscription

Actual behavior

Won't even let me pick file

The issue only arises because new pipe doesn't ask for storage access permission when trying to import subscription by clicking on import from> previous export under subscription tab.

Screenshots/Screen recordings

No response

Logs

No response

Affected Android/Custom ROM version

Color OS v6.0(android 9)

Affected device model

Oppo Realme 1 CPH1861

Additional information

Note: I figured out the reason why it's because new pipe doesn't ask for permission for storage at startup so when the import is clicked it launches android file picker but if you go to settings and try to set download location it asks for permission or just manually enable storage access in settings or app info depending upon your OS and ROM then when you try to import subscription it uses newpipe's native file picker which works fine entirely.

Same issue but for "Export database" function.
I cannot export "my channels/subscriptions/playlists/settings" with this NewPipe v0.24.0. It say something like "No app can to manage this action". Help please? Thank you!

Whew, this is using an old phone. As by emulator testing it is not an issue over API version 29 where the new StorageAccessFramework is being used.

No special App permissions needed

Can confirm the bug exists still on v27.7 on SDK API < 29

I now question if this is an android "bug"

This only happens if this setting is enabled tho. So it is in fact using an old android SAF.

Without SAF:
Without SAF the Permissions are requested and one is able to use the internal Newpipe File Picker

With SAF export
So if you export a file with SAF you are permitted to import it again.

Turns out these older Android versions don't really support the MIME Type "application/json".

This means it is not a permission issue.

Hi, I'd like to work on this permission bug for subscription import. Planning to add a runtime permission request before opening the file picker. Will test on Android 9+.
