Calendar sync crashes with NumberFormatException

  • A

    There are some appointments synchronised, I used 0.5.7-alpha from f-droid. The logcat message is the following:

    Much earlier in the logcat, while starting davdroid i get the following error message, but I guess thats not related to the problem:

    Looks like an Android bug: documentation says that the duration field is the “duration of the event in RFC2445 format”, but the calendar provider doesn’t seem to accept the same formats as defined in RFC 2445.

    Which Android version do you use? And can you post the details of the event (iCal)?

    I’m using Cyanogenmod M2 on a Nexus 5, but if I remember correctly the same problem occured in stock 4.4.2 as well.

    Just imported my whole ics-file to an owncloud instance and got errors, that 00001231T000000Z is not a date. So I checked the file and found:
    CREATED:00001231T000000Z .Maybe thats related to the problem because in the logcat it said

    01-29 01:47:43.576 E/DatabaseUtils(11605): java.lang.NumberFormatException: Invalid int: "T0"

    Working on this… at least 3 problems so far:

    1. Android bug: RRULE UNTIL component limited by 32-bit UNIX time → reported

    2. Android bug: DURATION=0 sec causes the NumberFormatException from the report

    3. So how to deal with DTSTART=DTEND all-day events, when setting DTEND is not allowed for recurring events and DURATION=0 crashes? DURATION=null works, but isn’t documented. DURATION=1 day would be wrong for “events on that day”.

    It will need more time…

    @werbung1975:

    DTSTART;VALUE=DATE:20130121
    DTEND;VALUE=DATE:20130121

    Is this really a 0-second event on 21 Jan 2013? If it’s an all-day event on this day, the iCal would have to be

    DTSTART;VALUE=DATE:20130121
DTEND;VALUE=DATE:20130122

    because DTEND is non-inclusive. See http://permalink.gmane.org/gmane.comp.mozilla.devel.calendar/894

    Could you please try whether OwnCloud generates DTEND=DTSTART or DTEND = DTSTART+1 when you create an all-day event for this day? In the first case, there would be an OwnCloud bug (aside to the DAVdroid, Android, … etc bugs related to this issue ;)).

    Hi rfc2822,

    Unfortunately, wide-known Yahoo! Calendar service generated such iCAL records several last days (definitely. I exported events as *.ics and reviewed them).
    It may be Yahoo’s problem technically, but really it’s user’s problem.

    The event was created on an old Nokia phone from 2007 synced with gmail via active sync protokoll (Nokia Mail for Exchange) and than exported from gmail as ics-File. It is supposed to be a whole day event. I think those events where sometimes changed to events from 00:00 to 23:59. So I guess its not an owncloud issue.

    I also tried the following app, but it crashes as well:
    https://github.com/gggard/AndroidCaldavSyncAdapater/issues/157
    because got confused by the names of the apps, I wrote the bug-report to Marten Gajda from CalDAV-Sync. He told me that in his app such events with DTSTART = DTEND get a duration of one day (Thank you Marten).

    Thanks for the info.

    I’m going rewriting some DtStart/DtEnd logic (also introducing better unit tests).

    For now, my proposed “solution” is that all-day events must always last at least one day (DTEND >= DTSTART+1). If DTEND is missing (“events on that day”) or DTEND = DTSTART (invalid all-day events like those posted above), DAVdroid will set DTEND := DTSTART +1 (because that’s the only value that makes sense) and thus prevent Android from crashing.

    By the way, I wonder when CalDav-Sync goes open-source…

    Hey the new version does not crash anymore, thanks! However those events with a UNTIL-date still show up only once. Do you want me to create a new issue or are you waiting for it to be fixed in android?

    @werbung1975 Can you please try to set the UNTIL-Date to something before 2038 in the iCalendar?
