Any news on this?
Google CardDAV: Received GET response without ETag
-
I have a android 8 device, with no Google services, no Google Play, nothing. I use Davx5 to sync contact from gmail account but I have a problem that the sync only work if I do it manually. If I create a contact in chrome in 15 minutes, I will have and error in my device. This error (is in spanish sorry):
And the log is this:

Someone can help me to sync contacts automatically? Thanks.

Hello,
This seems to be a problem of your CardDAV server: it returns a .vcf response without an
ETag
, which is not allowed by CardDAV because theETag
is required for synchronization.Such bad behavior is one of the reasons why Google CalDAV/CardDAV is not officially supported by DAVx5.
I strongly recommend to use a CardDAV service that behaves like specified in the CardDAV standard.

I need a free cloud service like google contacts to sync contacs in an android 8.1.0 device that have no Google services, no Google Play, it have nothing. What do you recommend me?

Have a look at our list here:
https://www.davx5.com/tested-with
There are plently of services that are free also. But as for all free services you have to question why they are free and how they are financed. Maybe host it yourself on a Synology or Nextcloud :)?

It’s weird because on tested-with google is included as those tested, it’s actually #17 in the list. But it seems you’re saying google is not supported?
This is sort of new, BTW, it was working fine for quite a while. I believe before the last 2 updates I got from f-droid everything was fine (last one 2.4.0-1). At times it works, but when it doesn’t, it doesn’t for quite a while. Might be Goggle changed something as well (as mentioned I had no issues before)?

Yes, Google is changing a lot all the time and they deprecated older APIs recently. Some people report its working, but we’ve now disabled the entry again, because it makes too much trouble for us to support a service which constantly changes and which is also not very well tested by Google itself.
