Hi,
I’m getting a 415 error code while trying to sync my caldav calendar with my android 4.2 which I did not have before (using the same calendar, hosted on Owncloud, and also syncing by davdroid).
I had to change my certificate recently, but apart from that, there has been no other changes (client side or server side).
I fetched the log :

So, if you could help me, that’d be great 
Best regards,

Thanks for your report. The logs are incomplete, could you please include the network traffic? Please do the setprop calls described in https://github.com/bitfireAT/davdroid/wiki/How-to-view-the-logs.
It sounds like your OwnCloud doesn’t like the Content-Type of an uploaded contact/event.
Also, which OwnCloud version do you use? Is there a way to reproduce the issue or do you have a test account?
Thanks for your help and your app

I don’t know about the content type. As I said it, I was able to use Davdroid with the same Owncloud account some months before (after that, I left it unsynced -cert error- for some time and only reset it a few days ago).
I tried with evolution, it works.
I use owncloud 6 (ooops, I just realize I forgot to update it, I’ll do it right now :))
I can create a test account, yeah.
Seems to be a server issue. The MIME type for iCalendar resources is text/calendar, but the server rejects the iCal file with “415 Unsupported Media Type”.
OwnCloud 6 seems quite old. I guess this has been fixed in OwnCloud because I haven’t seen this problem with OC 7 or 8.
Problem solved, although I have no idea what caused it.
I updated Owncloud from 6 to 8 (I had to update to OC7, you can’t do it directly, if that can be useful), but I did not solve the problem, I still had a 415 error.
Then, I tried using a different account. It worked fine.
So I knew I just had to delete and re-create the account for the calendar, which I did, and it worked.
Unfortunately, since the base calendar app for android is really a shitty application (and I’m being polite) which does not allow neither the import nor the export of the whole calendar, I had to send each events one by one by email to import them back after recreating the account. But when trying to import them to my calendar (the davdroid one), it only allows me to import them to the Google account calendar, but not to the caldav one…
(I’m not asking for help, just complaining about that app, it helps :))
Anyway, thanks a lot for your help, and for providing us with such a great app
OK, so I’ll close this issue now as it works for you.
