@acu It’s the base64-encoded Java hashCode of the address book URL.
Which contact app is not able to decide the address book
I use oxygen Android and sync with DAVx⁵ some address books with my nextcloud.
If I want to save an address I can’t decide the address book.
Which contact app is able to this?
- Are the calendar entries there?
- In Android settings / Accounts, are there “DAVx⁵ address book” accounts or only “DAVx⁵” accounts?
Could be possible that the address book account has never been created yet, so there’s nothing to select.
Also, can you please provide the DAVx⁵ debug info?
there are various chinese manufacturers that seem to patch out the possibility of choosing a specific address book for saving the contacts. You can always use different contacts apps. For example Google contacts or Simple contacts.
Does that help?
