I've been running Radicale for years! I pulled all my Google contacts back in 2013 and have been using it and DavDroid (now DAVx5 in the article) for years.

CardBook for Thunderbird is another great plugin. Between all those tools, I have cal/contact sync across my Linux boxes and Android devices.
