From your description, DAVdroid does not create duplicate contacts. DAVdroid creates “raw contacts”, as does Gmail. For every person, these two “raw contacts” are aggregated by Android to one “contact”.Wait until Android aggregates the contacts (may take some time), or Merge them manually in your Contacts app (“merge”), or Choose “Contacts to show: only DAVdroid” in your Contacts app.
since 1.0x I sometimes get all existing addressbooks double in the account. I even checked the server and renamed the phonebooks: the server has only 2 addressbooks but davdroid gives me each address book twice (after changing the name, still the same - had hoped that I’d get one old one new)
Am I the only one with this effect? It seems however that it is working properly besides that - no matter which phone book I choose.
Can I help with some logfile to investigate further?
Do you use Horde?
The logfile of the resource detection would be crucial.
However, I strongly assume that your address books are provided multiple times by the server (with different URLs), and DAVdroid just detects them.
Is there a problem with that?
I do use Horde - is that the answer already? If not I can provide logfiles …
This horde problem was already seen in beta tests, see Address books duplicated by -system- group (I have moved the topic to the public forum).
