Android. Firebase: Could not parse the Android Application module

Question

My build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.1.3-2'
    ext.realm_version = '3.7.2'

    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'com.google.gms:google-services:3.1.0'
        classpath "io.realm:realm-gradle-plugin:$realm_version"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://maven.google.com" }
        maven { url 'https://dl.bintray.com/jetbrains/anko' }

OK.In Android Studio select menu: Tools->Friebase

1. Firebase-> Authentification
2. Click on Email and password authentification
3. Connect to your app to Firebase

and get error:

Could not parse the Android Application module

Answer 1

I've just resolve this problem. I was upgrading the old GCM to FCM, and the Firebase Assistant shows the same error message as yours.

Solved by:

1. Go to Firebase console, in the Settings of my project, download google-servics.json to app/ folder. (Replace my old GCM's json file)

2. doing Add Firebase to your app again,

Then I can use the Firebase Assistans of AndroidStudio, again.

Answer 2

For me, the issue was classpath 'com.google.gms:google-services:4.3.0' was giving error, then I changed to classpath 'com.google.gms:google-services:4.2.0', resync'd Project with Gradle Files', then pressed Connect to firebase, :D
