Android - Firebase Initializing in Instant App - Getting Exception

Question

This is my application class:

package com.example.myapp

import android.support.multidex.MultiDexApplication
import com.facebook.appevents.AppEventsLogger
import com.google.firebase.FirebaseApp
import com.google.firebase.FirebaseOptions
import com.google.firebase.firestore.FirebaseFirestore
import com.google.firebase.firestore.FirebaseFirestoreSettings

class App : MultiDexApplication() {
    override fun onCreate() {
        super.onCreate()

        // Facebook
        AppEventsLogger.activateApp(this)

        // Firebase
        FirebaseApp.initializeApp(this)

        val settings = FirebaseFirestoreSettings.Builder()
                .setPersistenceEnabled(false)
                .setTimestampsInSnapshotsEnabled(true)
                .build()

        FirebaseFirestore.getInstance().firestoreSettings = settings
    }
}

This is the error I'm getting. It's failing on the last line of the App class, FirebaseFirestore.getInstance(), saying it's not initialized, but you can see above that I am initializing it?

Does anybody know what I need to do to fix this? This is an instant app. I have put the google services json inside every module (base + app + instant) and have also added the plugin to each gradle.

It's just weird that it's obviously going past the initialize statement and still failing.

I'm looking through https://stackoverflow.com/questions/45977847/make-sure-to-call-firebaseapp-initializeappcontext-first-in-android and a few things you can try: 1. check com.google.gms:google-services version, 2. re-grab your json file — TWL, Aug 20 '18 at 19:24
Or looking at https://firebase.google.com/docs/firestore/quickstart, under "Initialize Cloud Firestore (Android)" it says you don't need FirebaseApp.initializeApp(this)? Compare that to (Java) description. — TWL, Aug 20 '18 at 19:25

For me none of the solution worked that were given any where. Only this worked. Just had to download grade my google services from 4.1.0 to 4.0.0

dependencies {
    classpath 'com.android.tools.build:gradle:3.3.0-alpha08'
    classpath 'com.google.gms:google-services:4.0.0'
    /*classpath 'com.google.gms:google-services:4.1.0' <-- this was the problem */
}

So if you have updated the google services, just try to downgrade or change to an older version.
