@rfc2822 Hmm… did you read everything properly? That’s exactly why I wanted a patch. - to not have to change it manually.
I have read it, but I’m not sure that I understand it correctly. Are you asking for a patch in a CalDAV client, which
- detects which server in which version is running on which URL,
- whether the server is OwnCloud and its version changed from 8 to 9,
- in which case, it tries out whether the new service URL is
/remote.php/dav, but only if the old URL was
just because some server software has changed its default URL?
I can understand that it’s cumbersome to change the URLs on all clients, but technically, you run a completely different service.
If you want to minimize migration work, you may redirect
/remote.php/dav on your server (.htaccess) and use the new URLs only for new accounts (i.e. set them as well-known URLs).
Could you at least hardcode the new address in the next update?
The are no hardcoded URLs in DAVdroid, and I don’t see any reason why there should be such.
