Answer 1

Pretty much the same answer as everyone. You need to update all the firebase and google play services stuff. The thing to take away is that FIREBASE AND GOOGLE PLAY SERVICES VERSION ARE NOT ALWAYS IN SYNC ANYMORE APPARENTLY. So if you are using something like

ext {
    firebase_version = "15.0.2"
}

Just ditch them. For all the versions and stuff,

• Click here for Firebase
• Click here for Google Play Services
• Click here for Google Service Plugin
