Hi,
I just got my Fairphone and installed FOOS directly, really happy!
I will also try to get rid of google calendar, but I need it right now to sync my calendar with other people. I have installed aCalDav and it works fine (a little slow to sync at the beginning).
- Download aCalDav
- Create a new aCalDav account (settings/accounts…)
- you will find the URL on this page (the email address for me was @gmail.com, not google.com): https://github.com/gggard/AndroidCaldavSyncAdapater/wiki/Server-Compatibility-List
- let the phone synchronize. It takes quite some time and it was only partially synchronized for me. First I had only my main calendar, but not the other ones. I deleted the aCalDav account and created a new one. This time, without the /events at the end: https://www.google.com/calendar/dav/my.email.address@gmail.com. It worked, but some events from a subcalendar came only after one day. I wonder why!
I will try to find another way than google to synchronize my calendar with other people, but not everyone shares my concerns !
