Now, all is well.
I used 2 free applications that I deleted because the automatic synchronization no longer worked.
With DAVx5, everything works perfectly.
It’s user friendly and very simple to use.
I’m running owncloud 10.0.10.4, calendar 1.6.1
I already share my agendas with 2 thunderbird and 1 android phone with davdroid that I bought.
Now I get the message "no access possible to Caldav or Carddav on Davx5 188.8.131.52-ose installed for free from f-droid.
I customized connexion with “URL and user name”. Url is “https://www…/remote.php/dav/userid”
Userid is “userid”, password is my password connexion to owncloud.
I read a comment on play store saying that davx5/davdroid is not working with owncloud. Any idea ?
Everything is working perfectly now. The address you get to give DAVX is this : “https://www/folder whereowncloud is located/remote.php/dav/calendars/userid/calendar name/”
Now, you get to synchronize the name of the account in order to make the related calendar app display the calendar.
