I’ll close this issue because I think it’s a duplicate of #51 and it should have been fixed with 0.5.4 (see release notes). Please try with 0.5.4+ (uninstall DAVdroid, install 0.5.4 or later, add account again) and if this issue persists, please comment here and I’ll re-open the issue.
Sync error without OpenTasks
I use Davdroid to sync with Owncloud. I do not sync tasks and did not install OpenTasks. Then, I get the following sync error:
08-01 13:54:11.269 10623 11056 E ActivityThread: Failed to find provider info for org.dmfs.tasks 08-01 13:54:11.279 659 697 D SyncManager: failed sync operation Owncloud u0 (bitfire.at.davdroid), org.dmfs.tasks, USER, currentRunTime 5133228, EXPEDITED, reason: 10119, SyncResult: databaseError: true stats  08-01 13:54:11.282 659 697 D SyncManager: not retrying sync operation because the error is a hard error: Owncloud u0 (bitfire.at.davdroid), org.dmfs.tasks, USER, currentRunTime 5183103, reason: 10119
Only when I manually change the synchronization interval in Davdroid for tasks from every 240 minutes to manually, the synchronization works without errors.
Yes, I am using Android 6.0.
