I got this exception a couple of times too. The problem usually happens when you're using different versions of play services and firebase. What I've found to work is called a version resolution in gradle:

In android/app/build.gradle:
at this line:

compile project(':react-native-firebase-analytics')

transform this into:

compile( project(':react-native-firebase-analytics') ){
  exclude group: 'com.google.firebase'
}

Then below that add this:

compile ("com.google.android.gms:play-services-base:10.0.1") {
    force = true;
}
compile ('com.google.firebase:firebase-core:10.0.1') {
    force = true;
}

**make sure that if you're using react-native-fcm, that you resolve firebase-messaging this way as well. Every firebase and play-services library that you're using should be using the same version.
