How to Android without Google
Enable Google device registration
Enable Google Cloud MessagingI run Android without Google. I bought a new phone, and when I powered it up, it tried to get me to "sign into Google". I declined.  I downloaded F-Droid. Then I disabled every Google thing that could be disabled.After that, all apps came from F-Droid.  Mail is via K-9 mail and an IMAP server. Browsing is Fennec F-Droid, which is Firefox minus some unwanted Mozilla-calling stuff. Mapping is ZANavi. Location provider is Mozilla. Works fine.
