Ok, so I’ll close this. If this issue persists and if you think that DAVdroid could do something better, please post here again and I’ll re-open.
Caldav works Cardav doesn't work with Sony Android phone
I just installed DAVdroid on my sony xc with android 8.0
I entered my base URL and login credentials
Then I selected the account in DAVdroid.
Granted contact, event and task access permissions.
Then I select the calendars I want to have synchronized so that they are shown with checkmark (). And all my calendars do synchronize!
And I tried to do the same with the address books, but DAVdroid can’t find my address book.
Do you have any suggestions, what I can do?
Sorry, for my poor english - hope, it is good enough, that you can understand what my problem is about.
Thanksand best wishes from Cologne
Which server do you use?
I use t-online.de
I ereased the account, did the whole process again, now it works…
