Hello,
I am using DAVdroid to sync my calendar and contacts with my synology NAS.
Everything was (and is) running fine with (remaining) android 4.x and 5.x (devices)
Since yesterday I have problems to sync my calendar with android 6.0 (clean install on nexus 6).
Contacts are working fine, but when I sync the calendar the app is terminated.
I do not get any entries from my Caldav server.
When I add a new entry on my android device the new entry is successfully synced to my Caldav server.
I tried to get the verbose logs, but the command:
adb logcat | egrep ‘^(E/)|(./davdroid)|(./HttpClient)|(./Wire)’
does not work on my Windows Computer 
What can I do to get the logs?
By the way:
When I set: “setprop log.tag.HttpClient VERBOSE” what is the default?
I think after getting the logs it should be reverted to default.
Is someone seeing the same error?
Thanks in advance & greetings from germany,
torsten
Hello again,
I found something in the logcat screen:

edit by admin: add ``` to make logs monospace
Does that help to narrow down the cause?
DavDroid 8.4.1 from Amazon Store
Nexus 6 with Android 6.0 Build MRA58K
Caldav on Synology DSM 5.2-5592 Update 4
Thanks in advance,
Torsten
Is there anyone who has already tried DAVdroid/0.9 with Android 6?
Please tell us if it works for your or which problems you have.
This problem has been fixed with DAVdroid 0.9.0.2, the new permissions model will be implemented later.
With DAVdroid 0.9.0.4 (original, not from amazon store) everthing works fine again. Thank you very much.
