Sync error

jtg

I have been using DavDroid for quite some time. Some time ago it started throwing errors after each sync, albeit the syncs themselves succeed (or at least I haven’t found any difference between the server and my device yet).

The device in question is a Samsung S4 mini, running Android 4.4.2.

The relevant parts of the logcat output are as follows (filtered by egrep davdroid\|HttpClient\|Wire

I/davdroid.SyncManager(22907): Full synchronization forced

The last two lines are repeated 4170 times, if I count it right.

Any idea what might be going on?

Hi, I experience the same problem.
Syncing with davdroid//0.8.4.1 from Owncloud 8.1.1 on a raspi to my samsung S5 mini (Android 4.4.2) I get the contacts synced in both directions and the list of calendars, but no entries in calendars and tasks.

In the logs I get
snippet.txt

rfc2822

This seem too be two different problems.

@jtg Can you please post an example of your calendar (.ics) files?

@74alex When the ical4j library (which is used by DAVdroid) isn’t initialized correctly, this error may occur. Is this reproducible every time you start the sync process? Did you try to uninstall and re-install DAVdroid (there has been a change in the Manifest that might be related, and maybe the new Manifest hasn’t been processed somehow)?

Please see an example at the end of the message. I use a number of tools to access my calendar, however, so I’m not sure how characteristic this example is.

@rfc2822 I tried to reinstall but no effect. Still stops working. What should I do next?

edit:
I reposted a new thread at ical4j-exception-when-syncing-calendars

A found another entry, that seems more interesting, by exporting the calendar using the “Calendar Import/Export” app and comparing it with the copy stored on the server. Quite a few of the entries show difference similar to the following (diff -u output, lines marked with + come from the version on the Android device). To the best of my knowledge, the entry was synced from the server to the device.

Does this give some hint?

@jtg
For the record, I no longer experience this issue. I’m now using version 0.9.1.3 but I suppose the problem went away with version 0.9.
