No calendar sync after upgrade davdroid 0.6.1 -> 0.9.1.2

[hhmb_001]

It is not possible to sync my calender after upgrade davdroid. I try to sync with ownCloud 8.1 and use the DAVdroid client (0.9.1.2) with Android 5.0.2.

The sync stopps with [error] I/O exception during sync, trying again later - EXCEPTION: java.net.SocketTimeoutException: timeout

I'm confuse - If I make a downgrade back to 0.6.1 it works fine and this error not exists.

DAVdroid Log:

Can anybody help me with this error?

The sync of contacts works without problems.

Hello,

It's the same problem as described here: OwnCloud timeout. OwnCloud takes longer than 45 seconds to begin listing the calendar items, so DAVdroid times out.

In my opinion, this is an OwnCloud issue, please follow up at https://github.com/owncloud/calendar/issues/995

@rfc2822 But why works the sync with DAVdroid 0.6.1 and the same OwnCloud version?

Because DAVdroid 0.6.1 uses a PROPFIND request instead of REPORT calendar-query, because it doesn't support VTODO (tasks). PROPFIND causes other problems too, the right request is REPORT calendar-query.

@rfc2822 Thanks! I follow https://github.com/owncloud/calendar/issues/807 too.
