@rfc2822 Thank you, this helps a lot, it is a subscription of a shared calendar of an openXchange suite. Seems this error has always been there, but ICSX5 has begun to fail just with the pre-former release. I will contact the server software provider…
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.
