WebDav Mount are not recognized by the system file picker anymore [GrapheneOS]

[smellouk]

Problem scope

• I'm sure that this is a DAVx⁵ problem.

App version

• I'm using the latest available DAVx⁵ version.

Android version and device/firmware type

Android 16 (GrapheneOS)

Steps to reproduce

1. Make sure to mount a webdav
2. Go to System Backup and try to select the mount point

Actual result

During backup, I can't select the mount point from the system picker. This behaviour is the not reproducible with previous release. Also the mount is available on the File app but not available on System

Expected result

Mount points should be available to system.

Further info

No response

Got the same problem, same Android version.
Let me know if I can provide logs.

For me, webdav mounts that worked before disappeared after the upgrade to 4.5.12-ose
The davx5 app still lists the webdav mount, but others "cant see" it.

@ArnyminerZ I tried it by removing the app completly and unfortunately it didn't work. Can you recommend me next steps ?

[FelixDamrau]

Kinda the same on my side.
I want to use the webdav mount for the android backup, but the backup settings tell me "webdav mount N/A"

Maybe this is an issue not directly related to this wonderful app.
I can see the webdav mount in my file system -- but davx5-ose somehow doesn't "forward" this info to the system. :/

[ArnyminerZ]

Mmmh... I'm not sure about your setup, but everything seems to work fine on my end, at least with Material Files. Can you give me a bit more information? Have you tried removing the mount completely and adding it back?

[FelixDamrau]

Sure, which information do you need?

Here a summary of what I did so far:

• Remove the webdav mount and readded it - with the same name,
• Didnt work
• Removed again, added with another name
• Didnt work as well

I can see the webdav mount in my file system (native GrapheneOS "Files" App)
But I cant see it in the Settings -> System>Backup window (that's where I took the screenshot)

I have the same issue on FairPhone 6 with e/OS/ Android 15

I have tried removing and adding back the WebDAV without success, same as previous users.

I'm facing the same problem, the webmount is no longer available for seedvault backups on grapheneos.
Midnight commander can still access them though.

Would have been nice to mention this change in the change logs though.

That was the plan, I forgot to do so. Added to release notes.

[SparWiz-Khalifa]

So, did I understand right that we are basically waiting for Google to fix their bug in order for WebDAV mount to work again for Seedvault?
So this might happen in the next couple of days or weeks, most likely?

[rfc2822]

I'd rather like to know why it's not working with Seedvault, we were not expecting any problems. It's just another name for the provider, it shouldn't matter.

[rfc2822]

Seems that Seedvault contains an allow list that lists the old authority:

https://github.com/seedvault-app/seedvault/blob/e33368792940751536704c5d57176fa9a9a1237f/app/src/main/res/values/config.xml#L13

That would explain why it's not possible to sync with the new authority anymore.

I suggest to add the new authority to Seedvault. Could someone create an issue for that? Done: seedvault-app/seedvault#1014
