Usage
The client can synchronize data from Android calendar with the server under the following conditions. For this reason we do not recommend to use automatic synchronization. It is better to do a manual synchronization instead it.

• Use an item Sync now to provide a manual synchronization
  

Working

• synchronization of events added via Android
• synchronization of events added via webmail
• synchronization of events modified via webmail 
• change of time, date, transfering events to all-day event and back
  
• synchronization of all-day events modified via Android

Known issues

• changing of an existing event with a time in Android – the only tested way is to first convert the event to full day:
  • choose the event you want to modify,
  • convert it to full day event -> synchronize it,
  • now modify the full day synchronization and make the changes (date, time, name...) -> and synchronize.
• Repeating events can synchronize wrong way if you modify (delete) only certain events in a

If an error occurs during synchronization - CalDAV sync error (general), it is necessary to delete the event that is causing it (usually an event with a set time that has been modified in Android Calendar). Only then you will be able to continue with the synchronization.
