Android: Directory contents empty in app while web frontend shows file

[nakal]

Actual behaviour

File list is empty in some folders on Android while there are files in the web frontend (same user).

Expected behaviour

Viewing contents of a directory in the Android app should always be consistent with that what the web frontend shows.

Steps to reproduce

1. Make some directories.
2. Upload files.
3. Check contents, some folders might be empty, even you uploaded files there.

I see a similar behaviour, yet noticed it only with images. The images shown in the photo view are not visible in the file view.

[nakal]

I can confirm that it happens with images in file view exclusively. And also I've found partially shown directories. E.g. 2 of 12 images are shown.

[ne20002]

I also confirm this bug.

[tobiasKaminsky]

Can you create us a test account, test if the problem occurs also there and if so send the credentials to tobias at nextcloud dot com with a reference to this issue?

[LunaticTazz]

I can do that. Give me a day to set it up and test it, as I'm busy at the moment.

[tobiasKaminsky]

I think this is fixed via https://github.com/nextcloud/android/pull/4470

So for some reason the files were uploaded, but stored with a wrong upload path, which does not affect storing it on server, but they got stored wrong in our internal database.

On a clean installation all files are found, so it is not a problem with sync, but how they got stored initially.

I try to reproduce it, so I do not need any test account.

[tobiasKaminsky]

It seems like this

• auto upload images, move them to NC folder
• see them in folder, within our app
• open photos view
• see downloaded photos
• go back to auto upload folder
• images are not there anymore
