Description
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 beta)

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.
Also check out the paid version CardDAV-Sync beta. It syncs some additional fields (like company/organization and notes). For details see my website.
Please uninstall the free version before you install the paid one (and vice versa).
Note to Yahoo!® users: Due to the many issues on Yahoo!'s servers, Yahoo! is no longer officially supported by this app.
After the installation got to "Settings" > "Accounts & Sync" and create a new Account.
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 who 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.
Features:
* Sync contacts from a CardDAV-server (tested and reported to work with DAViCal, SOGo, egroupware, Zimbra, david.fx, Fruux, ownCloud ... and more. See my website for details)
* basic support for self-signed certificates
* auto-provisioning
* 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 and birthdays (but please visit "date formats" on my website first)
* 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
It is still under development and some important features may be missing. Known limitations are:
* organizations, instant messengers, categories, notes and websites are *not* synced by the free version
* SOGo Contact lists are not supported yet (work is in progress)
* 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)
* and maybe more
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.
known issues:
* @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)

Excellent sync! I've been using this app for months now. I've been flashing my phone and needing to download my contacts using this app and it has [never] failed. Works perfectly! Syncs to phone with no issues. And changes made can be updated to iCloud contacts. Thank you for the app that makes this a lot easier

Fails with ownCloud Fails to verify ownCloud. Maybe if this project was OPEN SOURCE, this problem would be solved.

Buena app Hace lo que promete, consume poco espacio. No permite renombrar la cuenta, pero no es algo indispensable.

Wonderful App This is the best app I've ever used. Works seamlessly. Never had to do the manual update of my address book when I switched from iPhone to android. Will definitely recommend to friends.

Doesn't accept username/password With Use SSL enabled, username/password rejected immediately. Without, won't proceed to next screen. Was going to try the Calendar app, but won't since I can't get this to work. :(

Does not Do Anything on my NOTE2 I downloaded CardDAV-Sync Free and it did now work at all. I entered the information as required and it tried to verfify my Yahoo! information and it just returned to the cofiguration screen and did not sync any contacts. I had just pulled down the SmoothSync for Yahoo Calendar and it worked flawlessly and was in hopes that CardDAV-Sync Free would operate that way as well. Sorry for the poor review, but it did not work for me. Could have been Yahoo servers, but the their servers worked with my IPhone4 and hooking in with a carddav sync with no problems. Is there any difference between the free version and the paid version????
