Both issues have gone away with 1.6.5-ose from F-Droid. Thanks for the update.
iCalendar parsering - ical4j exception
-
Hello!
My Davdroid log:
https://drive.google.com/open?id=1piBL3d3wr6qLw_8kwPRRRUtURsOSZUBXI am running Davdroid against my own caldav server. Synchronizing(REPORT) VTODOS seems not to work. When looking Davdroid log, I can find ical4j exceptions. With my iCalandar knowledge I can’t find any fatal error in iCalendar content. Could some look my log, if you could say what’s going wrong here.
regards

http://10.0.2.2/juha/neo/rush8crr2a203728.ics seems to be an invalid iCalendar. Have a look at line 30, but the error may has its root in another line. Can you post this resource (without private data)?
How did you create these tasks?
Does synchronization work when you create the task on your Android device?

This iCalandar is generated by a server that I have written myself.

It seems the iCalendar is invalid. Please double-check it, including the VTIMEZONEs. You may also use a validator.
Also, please use correct formatting for such data. It’s really hard to read it otherwise.
If you think that your iCalendar is correct and it’s a DAVdroid error, please provide an iCalendar file to reproduce the problem.

Now I get it to work. Datetime formats where wrong. iCalendar.org validator did not detect these problems. I find this errors using severinghaus.org validator here:. It is based on same iCal4j library.
