I come from Android and I use “group” to group my phone contacts.
When I import my contacts into nextcloud-16.0, I don’t think the group is picked up. Then I manually set a contact into a group on the server and sync them. I don’t see the group is created nor the contact is placed under the group.
Groups are supported as long as they are stored as “categories of contacts” and not “separate VCards”. The DAVx5 app on Android e.g. provides a configuration option for it.
Login my nc account via firefox, click on “Contacts”, click on “Settings” on the left lower corner, click on “Import into”, select the contacts.vcf which was generated in gmail;
When the import is done, the group field are not populated at all. The “group” is the “label” in gmail.
Should I do it via “DavDroid”? I did too and the results are the same, no “group”.
I don’t know in which version (v3.0/4.0) Gmail exports contact records and if the category field is correctly populated. Please check the content of the vcf file with a text editor.
Example:
BEGIN:VCARD
VERSION:3.0 # <<< version number
...
FN:Mr John Doe
N:Doe;John;;Mr;
CATEGORIES:Work # <<< category field
...
Yes, I think you’re right. It seems that the vcf export function strips some fields.
I recommend to give a csv to vcf converter tool a try. See e.g.:
