DAVdroid 1.5-ose does not synchronize address books
There was a problem in DAVdroid 1.5-ose which caused DAVdroid not to synchronize address books. This problem has been fixed with DAVdroid 126.96.36.199-ose.
How can I download 188.8.131.52 from F-Droid?
There’s only version 1.5.0 available.
My problem is I got not addressbook and contact list for Davdroid at ma contacts.
If I try to add the addressbook at my account settings, my settings will freeze completely and I can only close the task by button.
After I open the account settings there’s still noch addressbook.
