Not all calendars listed

---

Hello. Thanks for your awesome app!

mailbox.org exposes it’s calendars via CalDAV. There is an extra calendar (Tasks/“Aufgaben”) which which is not seen by davdroid. It has a special tab in their web ui but its caldav url is similar to the other calendars: https://dav.mailbox.org/caldav/XXX, where XXX is calendar ID. For the tasks it seems to be ID == 27, and for others its a dynamic ID.

I can import the tasks calendar fine into thunderbird and it works like normal calendars. I wonder why davdroid doesn’t see it. There isn’t a way to manually add it either.

DAVdroid checks for CALDAV:supported-calendar-component-set and ignores collections that are not supposed for VEvents: https://github.com/rfc2822/davdroid/blob/ec94fe61fd4af92cd253100b375176e3816c92cd/src/at/bitfire/davdroid/syncadapter/QueryServerDialogFragment.java#L191

I guess that the Tasks collection is not suitable for VEvents (even if they might actually work), so DAVdroid doesn’t show it would be intended behaviour.

For details, please provide logs.

Thanks for your pointer. I didn’t look at the logs but I’m pretty sure the tasks one is a VTODO component (the semantics in Thunderbird/Lightening support this).

Is it possible to support VTODO in DavDroid?

Please follow up at #34 to get informed about task syncing in DAVdroid.
