An update to OC 8.2.1 solved it for one device, but not for another. An update to davdroid 0.9.1.2 solved it for the other device. So not too sure what the issue was exactly.
iCalendar (hosted on Posteo) ACKNOWLEDGED format
I have a problem to use ISCdroid with a posteo calendar-feed.
When I try to add the calendar-URL, I get an Error:
‚Could not parse iCalendar resource‘
Faiphone with Android 6.0.1
I could send the URL to someone personally.
Thanks for your help,
Thanks for the URL. The problem are these lines:
ACKNOWLEDGED seems to be defined by this draft: https://tools.ietf.org/id/draft-daboo-valarm-extensions-04.html#rfc.section.8.1 and is understood and parsed by ical4j.
ACKNOWLEDGED is defined like this:
acknowledged = "ACKNOWLEDGED" acknowledgedparam ":" datetime CRLF acknowledgedparam = *( ; the following is OPTIONAL, ; and MAY occur more than once (";" other-param) ) Example: ACKNOWLEDGED:20090604T084500Z
In your iCalendar resource, there are two colons (:), which is not parseable.
So, this is an invalid iCalendar file. Please fix the your iCalendar or report this problem (including this analysis) to someone who can fix it.
