I cleared my address book and set up a new sync using 0.4.1 and indeed it displays some contacts now. Namely the same 5 contacts that I get on /remote.php/carddav/addressbooks/mimox/contacts. This means there have been two bugs, one on the client and one on the server side. The client side is fixed. Thanks a lot!
Keep contacts/calendars on device after deleting davdroid account
Is it possible to keep the synced contacts and calendars on the device after deleting the davdroid account?
perfect would be a dialog which asked for keeping information on the device on account deletion.
No. All contacts and events are deleted by Android when the respective account doesn’t exist anymore. If you delete an account, export the data before.
It might be possible to set the “owner account” of the contacts/events to
at.bitfire.davdroiddirectly, but I don’t know if this will even work and can’t recommend to do so as it would be non-standard usage with undefined results.
