# davdroid from f-droid. username ian,
# url https://iank.pw/radicale/ian.
# I disabled power management feature, it's got 240 min sync interval,
# so it shouldn't be bad.
#

# when setting up davdroid, switch to groups are per-contact categories,
# per https://davdroid.bitfire.at/configuration/radicale/
#
# set account name as ian@iankelling.org, per help text below the
# field.
#
# After setting up account, I added one address book, named
# ian. calender was already created, named ian. checked boxes under
# both. synced.
#
# ignorable background info:
#
# When debugging, tailed /var/log/radicale/radicale.log and nginx log,
# both show the requests happening. Without creating the address book,
# after creating a contact, a sync would delete it.
#
# Address books correspond to .props files in the radicale dir.
#
#  Some background is here,
# https://davdroid.bitfire.at/faq/entry/cant-manage-groups-on-device/
# which shows separate vcard option is from rfc 6350, the other is 2426,
# radicale page says it implements the former not the latter,
# which conflicts with the documentation of which to select, but whatever.
