CardDAV-Sync is a CardDAV client for Android to synchronize contacts. Due to its implementation as sync adapter it integrates seamlessly with the default contacts app.
(Also check out CalDAV-Sync)
Important note for Android 4.1 and Samsung users: To prevent the removal of your accounts on reboot install this app:
At present, Samsung users still need this workaround, even on recent devices.
Also note that many Android 4.x and 5.0 devices need the workaround to prevent removal of accounts during an app update.

If you find a bug send me an email please. Without detailed error description I often can't do anything especially when I can't reproduce it. It's also possible that your server has a bug that CardDAV-Sync can not (yet) tolerate or work around. If you report bugs I can fix them quickly and everyone will benefit.
This is the paid version of CardDAV-Sync beta. It equals the free version except that it syncs more fields. Visit my website for details.
Please uninstall the free version before you install the paid one (and vice versa).
Important! If your phone removes the accounts on reboot, move the App back from SD card to the phone. Some phones (if not all) can't handle sync adapters on SD Card properly.
For users which are unable to edit or create synced contacts I published an editor at the market. Just search for "Contact Editor" or see my website.
Once this app reaches version 1.0, I'll make it open source.
See http://dmfs.org/wiki/index.php?title=Open_source_status for details on the open source status.
* Sync contacts from a CardDAV-server (tested and reported to work with DAViCal, SOGo, egroupware, Zimbra, david.fx, Fruux, ownCloud ... and more. See our website for details)
* basic support for self-signed certificates
* two-way-sync (please, don't forget to backup your contacts before you use this! It is still beta!)
* syncs names, phone numbers, email addresses, postal addresses, photos, birthdays (but please visit "date formats" on my website first), notes, instant messengers, organizations, nicknames, categories (groups), phonetic names, related names and websites
* automatic address book discovery (works with most servers in default configuration)
* one-way-sync of Apple-style groups
* Support for Apple-style custom labels (X-ABLABEL)
* stores passwords encrypted
* supports efficient sync-collection request
* supports client certificate authentication
* import wizard for contacts from other accounts
It is still under development and some important features may be missing. Known limitations are:
* SOGo Contact lists are not supported yet
* only "server wins" and "phone wins" (default) conflict resolution available (that is when a contact is updated on server and on phone between two syncs)
Please report bugs. Feedback is very welcome.
Btw: just writing a comment like "Doesn't work on..." won't help neither you nor me to get it running on your device. Please contact me if you have problems.
* @david.fx users: david.fx returns all links to contacts from sub-folders. Currently this leads to the situation that some contacts may appear multiple times (joined to one contact)
Please send me an email if something doesn't work! Also check if you need to install the workaround app before upgrading, see the app description.
