    Hello,

    I got a NullPointerException in davdroid while parsing an ics with a VJOURNAL entry.

    The logcat output is:

    29150 E/AndroidRuntime(20206): FATAL EXCEPTION: SyncAdapterThread-1
29151 E/AndroidRuntime(20206): java.lang.NullPointerException

    The ics is

    BEGIN:VCALENDAR

    As a fix you could throw a ParseException so the VJOURNAL will not get parsed.
    at/bitfire/davdroid/resource/Event.java:120

                    // event
                ComponentList events = ical.getComponents(Component.VEVENT);
                if (events == null || events.isEmpty())
                {
                        throw new ParseException("",0);
                }

    I don’t have tested this, cause I don’t get the source compiled.

    Thank you for this greate app

    This check is already here: https://github.com/rfc2822/davdroid/blob/b35273a6d56aeada4fe00dbd97895b8a3d5070b2/src/at/bitfire/davdroid/resource/Event.java#L123

    Maybe the event is interpreted later although it’s empty, I’ll have a look.

    Can’t verify with most recent version, so I’ll close this.

    Can you check if this occurs with the newest version and if it does, please post again?

    As far as I understand your code, the Event get parsed in
    https://github.com/rfc2822/davdroid/blob/b35273a6d56aeada4fe00dbd97895b8a3d5070b2/src/at/bitfire/davdroid/resource/RemoteCollection.java#L90
    and in line 91 added to the resource. So you need some logic later to ignore other entries than VEVENT.
    With the exception thrown those got ignored.
    It fixed some strange behaviour where i got “Kalenderspeicher angehalten” or a android core deamon got killed after a “sync now”

    The parseEntity method returns if there’s no VEVENT (as posted above).

    So, does the newest version still have the problem?
