Original GitHub issue: https://github.com/floccusaddon/floccus/issues/1563

Which version of floccus are you using?

5.0.9 Android

Sync method

WebDAV

Which browser are you using? In case you are using the phone App, specify the Android or iOS version and device please.

Firefox 123.1.0 on a Google Pixel 4a with GrapheneOS sunfish-factory-2024021100 using Android 13

Which version of Nextcloud Bookmarks are you using? (if relevant)

No response

Which version of Nextcloud? (if relevant)

27.1.4

What kind of WebDAV server are you using? (if relevant)

Self-hosted NextCloud 27.1.4

Describe the Bug

No matter how often I use the back gesture, force stop floccus and floccus bookmark sync or reboot my phone, it will show a splash screen with the floccus icon (which I think comes from the OS itself), then immediately fade to that entirely blank black screen (white in light mode) with the only thing being displayed being the phone's status bar and the phone's bottom indicator for swiping up.

Expected Behavior

I expected floccus, after importing my json, to continue into any sort of UI, be it a sync screen, or further setup. In case of an error I expected floccus to display and error and provide a way to mitigate and try again, maybe provide some error code or similar that I could use in a search or an issue.

To Reproduce

Install floccus bookmark sync (5.0.9) in F-Droid from the F-Droid repository on a Pixel 4a running GrapheneOS release sunfish-factory-2024021100
import my json (can I upload this privately somewhere?)
Confirm the "Successfully imported profile(s)" with OK
still on the export/import screen now showing both profiles for export, tap the hamburger menu and tap the first of the two profiles in the menu (either Firefox root bookmarks folder or tabs, the UI doesn't distinguish between the two because they share the same login name)
the screen will go blank (white or black depending on Android's dark mode toggle) and no gestures, closing and reopening, force stopping of floccus and floccus bookmark sync or phone rebooting will get floccus out of that screen

Debug log provided

I have provided a debug log file

Hello 👋

Thank you for taking the time to open this issue with floccus. I know it's frustrating when software
causes problems. You have made the right choice to come here and open an issue to make sure your problem gets looked at
and if possible solved.
I'm Marcel and I created floccus and have been maintaining it ever since.
I currently work for Nextcloud which leaves me with less time for side projects like this one
than I used to have.
I still try to answer all issues and if possible fix all bugs here, but it sometimes takes a while until I get to it.
Until then, please be patient.
Note also that GitHub is a place where people meet to make software better together. Nobody here is under any obligation
to help you, solve your problems or deliver on any expectations or demands you may have, but if enough people come together we can
collaborate to make this software better. For everyone.
Thus, if you can, you could also have a look at other issues to see whether you can help other people with your knowledge
and experience. If you have coding experience it would also be awesome if you could step up to dive into the code and
try to fix the odd bug yourself. Everyone will be thankful for extra helping hands!
One last word: If you feel, at any point, like you need to vent, this is not the place for it; you can go to the forum,
to twitter or somewhere else. But this is a technical issue tracker, so please make sure to
focus on the tech and keep your opinions to yourself.

I look forward to working with you on this issue
Cheers 💙

I see this issue on 5.0.10 (also using webdav - via apache2). Rolling back to 5.0.9 on 2 phones both worked.

You may not need to rollback, https://github.com/floccusaddon/floccus/releases/tag/v5.0.11 is out

Downgrading didn't solve it and 5.0.11 doesn't solve it for me, either. I tried updating directly and also uninstalling and installing, then doing the import again. I just want to sync my bookmarks and tabs 😭

Just to be extra clear, it hasn't worked for me on Android at all so far. I'm a recent convert from iOS to Android

I recorded a video of my steps because I can't be sure I'm not doing anything wrong. Please let mW know if there is anything I should do differently

Hi @alinanorakari
I'm sure we'll get to the bottom of this. Could you send me your floccus export json file via https://cloud.marcelklehr.de/s/PCi3iLWrzdMZSmw ? You may replace your passwords with something less sensitive.

Thank you for providing the file. You have a tabs profile in your export, which is likely causing problems. The android app has no notion of tabs.

As a quick fix you can

Stop the app
Remove all stored data from the app
Re-export your profiles, this time without the tabs profile
Import again
Manually create a replica of the tabs profile in the android app

I'll soon fix the app so that tabs profiles will be converted to normal ones upon import.
