Thanks for the tip regarding version 3.0 and 4.0. The complete trace DAVdroid write to SD-Card contains “VERSION:4.0”. Owncloud somehow falsly converts it to “VERSION:3.0” without converting the values properly. So this ticket can be closed. Thanks for your help.
P.S.: This is my oc workaround: https://github.com/s3menzer/contacts/commit/5e5a813f8eaff6a77dc2b2f9abb533a5f973a5db
java.lang.NumberFormatException: For input string: ""
Since Davdroid 1.11 (or maybe 1.10) the synchronisation of my Horde tasks is not working properly. I get the error message For Input String: “”. When I deactivate the task list with the error for syncing the error appears for the next activatet task list.
Deleting and reinstalling multiple times does not fix the problem.0_1525852314332_debug.txt
