CalDAV-Sync is a CalDAV client for Android to synchronize events and tasks. Due to its implementation as sync adapter it integrates seamlessly with the native calendar app and widgets. Also check out CardDAV-Sync

To get task , please install this task app https://play.google.com/store/apps/details?id=org.dmfs.tasks

Since version 0.4 CalDAV-Sync s read-only sync of webcal ics feeds (via http & https).

Important note for Android 4.1 and Samsung s: To prevent the removal of your s on reboot install this app:
https://play.google.com/store/apps/details?id=org.dmfs.jb.workaround.caldavsync
Although this issue seems to be fixed in Android 4.2 the workaround is still required on Samsung devices.

Please note that there is a new issue in Android 4.4: http://code.google.com/p/android/issues/detail?id=66905
It causes s to be removed when an app is updated. Installing the workaround app should help.

This app will create new calendars on your device (one for each calendar on your server ).

Please send me an email if you find a bug. 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 CalDAV-Sync can not (yet) tolerate or work around. If you report bugs I can fix them quickly and everyone will benefit.

It is tested and works with
- DAViCal
- SOGo
- Zimbra
- OSX/iCal Server
- eGroupware
- Oracle Beehive
- david.fx
- iCloud
- ownCloud
- many more, see http://dmfs.org/wiki/ for a list of all servers reported to work

Note to Yahoo!® s: Due to the many issues on Yahoo!'s servers, Yahoo! is no longer officially ed by this app.

Note to Free.fr s: Free.fr doesn't CalDAV. However you should be able to sync your free.fr calendar one-way using the Webcal option.


After the installation got to "Settings" > "s & Sync" and create a new .

If there is no calendar installed on your device, go to my website and install CalendarProvider.apk and Calendar.apk (FroYo and Gingerbread only)
