Hi,
I’m experiencing a issue with DAVDroid: I have an owncloud calendar which is already synchronized with my laptop calendar client and works well.
I want to have this calendar on my smartphone too, so I’ve installed DAVDroid to synchronise with stock Android 7’s calendar.
I have two calendar in owncloud: a birthday calendar automatically updated from my contacts, and a personal calendar which I manage myself.
This is only my personal calendar which not working with DAVDroid.
Here is the debug output: https://pastebin.com/raw/mncPAGgF
Any ideas to help me ?
Regards,
Paul
Which calendar app do you use?
Hi @rfc2822 ,
I’m using Etar from F-Droid, but I’ve also tested with Standalone Calendar with the same message.
I think the problem is not the frontend application but between davdroid and com.android.calendar
@zato The problem occurs in this line:
weAreOrganizer = values.getAsInteger(Events.IS_ORGANIZER) != 0;
It seems that IS_ORGANIZER is null in your case, which I haven’t seen before and doesn’t make much sense. I wonder how it can be null and what this value should mean. Therefore I have asked for the calendar app, which has probably set the null value.
In the calendar provider table definition (latest 7.1 version), IS_ORGANIZER can indeed be null:
CalendarContract.Events.IS_ORGANIZER + " INTEGER," +
Do you think IS_ORGANIZER = null has the same meaning as IS_ORGANIZER = 0?
@rfc2822 said in Owncloud Calendar/DAVDroid synchronisation fails:
Do you think
IS_ORGANIZER = nullhas the same meaning asIS_ORGANIZER = 0?
Hum this question is for me ? because I have no idea of the answer, I’m not a developer 
Since my last answer, I’ve noticed something: if I create a new empty calendar it can be synchronized with DAVDroid, and if I import my ics file (previously exported from my personal calendar), then the error occurs again.
So maybe there an event in my calendar which can’t be processed ?
@zato Maybe the importing process sets this field to null. I’ll have a look at that and process null values as if they were 0, if it doesn’t cause other problems.
Should be fixed with davdroid/3132ffbd, which now allows null values for IS_ORGANIZER.
Change to Nextcloud
