The basic GroupDAV server at a general egroupware setup helps to serve both the CalDAV and the CardDAV services. The CalDAV service may be found basically by the following type of URL: http://some.server/egroupware/groupdav.php/calendar Opening this link in a browser helps to check if the service is active or not. In the former case the browser will show a list of events in an ICS format.
When doing my first setup, I basically selected this URL as my CalDAV source, selected a one-way sync, and selected (by the program's request) the personal calendar to sync.
After the sync I was able to see my personal events, and also the events where I was invited as a participant.
When chosing the calendar and infolog for synchronization with some installations this error arose:
org.apache.http.client.ClientProtocolException: calendar-query failed org.dmfs.dav.CalDav.calendarQuery(CalDav.java:1300) org.dmfs.dav.CalDav.loadResourceUpdates(CalDav.java:1145) org.dmfs.caldav.syncadapter.SyncAdapter.sync(SyncAdapter.java:319) org.dmfs.syncadapter.AbstractSyncAdapter.onPerformSync(AbstractSyncAdapter.java:96) android.content.AbstractThreadedSyncAdapter$SyncThread.run(AbstractThreadedSyncAdapter.java:247)
Simlpy not syncing the infolog, but only the calendar did resolve the issue.
If you can't create an account, try using the URL sample-server.com/egroupware/groupdav.php/calendar/
