AnkiDroid-folder unavailable #16275

Closed LovolaAnki closed 2 weeks ago

LovolaAnki commented 2 weeks ago

Hey everyone!

When I try to open Anki (using android) it says "AnkiDroid-folder unavailable" and then I arrive on a page for advanced settings.

It seems as it has to do with the /storage/emulated/0/Ankidroid folder.

The only folders that I can find is the following:

Haven't reinstalled or updated it. This just occured out of nowhere.

Is there any way to solve this? I have a folder with backup files. I have a folder with all the media (collection.media). So the data is there.

Google's revoked your phone's access to /AnkiDroid, see: https://github.com/ankidroid/Anki-Android/wiki/Full%20Storage%20Access

Thanks! Do you know why they have decided to revoke that access?

The goal of scoped storage is to protect the privacy of app and user data. This includes protecting user information (such as photo metadata), preventing apps from modifying or deleting user files without explicit permission, and protecting sensitive user documents downloaded to Download or other folders.

Apps using scoped storage can have the following levels of access (actual access is implementation specific).

  • Read and write access to their own files with no permissions * Read access to other apps' media files with READ_EXTERNAL_STORAGE permission

DA: READ_EXTERNAL_STORAGE is no longer usable

  • Write access to other apps' media files is allowed only with direct user consent (exceptions granted to System Gallery and apps that are eligible for All Files access)
  • No read or write access to other apps' external app data directories

https://source.android.com/docs/core/storage/scoped#app-access-restrictions

In addition: it means that Android wipes app data by default when apps are uninstalled

Closing this as a duplicate of #14423 (as there's no work to be done here)

Feel free to continue the discussion, just moving this out of our active work queue, as I believe we've improved this for 2.18
