⚠️ Before posting ⚠️

  • This is a bug, not a question or an enhancement.
  • I've searched for similar issues and didn't find a duplicate.
  • I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
  • I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

  1. Open the app (I'm already logged in, so log in if needed)
  2. Tap Favorites.
  3. Scroll down.
  4. It will crash after 2-3 seconds.

Expected behaviour

It should not crash.

Actual behaviour

It shows the files, but crashes after scrolling to the bottom.

Android version

16

Device brand and model

Pixel 7a

Stock or custom OS?

Stock

Nextcloud android app version

34.0.0

Nextcloud server version

33.0.5

Using a reverse proxy?

No

Android logs

No response

Server error logs



Additional information


Here's the stack trace, my 2 cents is that there's a listOf() that should be a mutableListOf() somewhere, so it used EmptyList instead of MutableList and blew up.


Cause of error

    Same error experienced on a Motorola Edge 50 Neo. Only 1 item in favourites, so app crashes as soon as favourites tab is selected
