New calendar showing up in DAVx5 but not in cosuming apps #1499

Hi,

I have just started using DAVx5 and I was pleased in the beginning.
Now I have added a second calendar on my provider side and it shows up in the DAVx5 app as expected. But when I switch to my calendar app (fossify), the new calendar doesn't show up in the CalDAV section (its the same behavior in the Google Calendar). How can I enforce the exposure of new calenders to the Android system?

Furthermore, it seems that the synchronization of my first calendar has stopped as well. I have checked the FAQ section and disabled all battery optimization on my Pixel 5 altogether.

EDIT: I just noticed, that the last synchronization in my old calendar is more than 3 hours old (although it should be synchronized every 30 minutes). Switching the synchronization on and off, doesn't change anything. The new calendar has no sync timestamp at all.

Can you give me a hint on how to solve this issue?

Cheers,
Frogtime

It seems to be a size issue. When exporting all events to ics, the file results in 1,2MB. Is this a problem? How can I sync calendars that span over several years?

No, that shouldn't be a problem. Note that the default time limit in the DAVx5 account settings is 90 days.

This exception happens during the update of the calendar metadata is is not related to specific events:

    EXCEPTION android.database.sqlite.SQLiteException: Row too big to fit into CursorWindow requiredPos=2202, totalRows=497

Newly switched-on calendars need to be synced once. After that they show up on a system level and in other apps.

You can turn on verbose loggin in the DAVx5 settings and then press the sync button inside the app. Wait until it is finished, click the notification amd share the archive with yourself to save it. Then have a look in the logs and maybe you see something that helps you identifying the problem.

Does it help to switch the Event colors (not Manage calendar colors) toggle in the Account settings?

Otherwise you may want to wipe the calendar storage on your device, see point 3 here.
