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. Please read the CardDAV-Sync FAQ first if you have any questions.
There is a page about the CardDAV-Sync account settings available.
- The contact editor in Android 2.x is not capable of editing contacts from custom sync sources (see Issue5988). To address this issue I've taken the contact editor from the 2.1 sources and fixed it. Contact Editor Pro is available at the market (a free version is available as well). The issue has been fixed in Android 4, but several devices are still limited in their capabilities and may need an external editor for certain tasks, see HTC Sense issue.
