Davdroid is creating duplicate contacts in my addressbook for certain contacts when synchronising from the server.
It looks like the only thing these contacts have in common is that they do not have any fields set beyond a name (fields are respectively: VERSION, PRODID, UID, FN, X-CALYPSO-NAME, X-MOZILLA-HTML). Contacts with anything else at all set (email, phone) seem to be fine.
The duplicate contacts appear to be created every time I manually sync.
I can reproduce this even after wiping my existing accounts and addressbook, with davdroid 0.6.1
I’ve reproduced it with other contacts (with e.g. email and phone set) too.
Can you please provide more information, including logs?
Yep, they have UIDs. I’ll see if I can collect some logs today.

Do these contacts have an UID?

I wonder if this is related, from the logs:

FWIW this phone only has no Google accounts on it and just one Davdroid account.
It seems like android is assuming the RawContacts.STARRED flag to be a long (ContactsProvider2.java:4517), while davdroid is creating it as a boolean (src/at/bitfire/davdroid/resource/LocalAddressBook.java:612)

Thanks for the info, I’ll have a look at this.
The STARRED flag is now set as an int which hopefully fixes this problem. If this issue is still present in the next version of DAVdroid, please feel free to post again / reopen the issue.
I built davdroid from source and gave this a try.
While the fix in 88972ae has helped - the exceptions in the logs related to the favorites are now gone - it doesn’t appear to have fixed the duplicates. 
Please reopen this issue (I don’t seem to have the permissions to do so).
Ok, so can you please read Reporting issues and provide all information mentioned there, including detailled steps to reproduce and verbose logs?
