FirebaseInitProvider. Resources not found [closed]

Question

I have been using Google Firebase for a while now in application and I was doing some maintenace and a few updates but I keep getting:

Unable to get provider com.google.firebase.provider.FirebaseInitProvider

This happens whenever I launch the application. I have already tried enabling MultiDex and my applicationId has been set ever since I started using FCM. I just don't know what it could be.

Any help will be much appreciated.

build.gradle (app):

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
    applicationId "com.vivatrucking.drivershub"
    multiDexEnabled true
    minSdkVersion 15
    targetSdkVersion 27
    versionCode 2
    versionName "1.0.1"
    testInstrumentationRunner  "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    // android

    implementation 'com.android.support:cardview-v7:27.1.1'
    implementation 'com.android.support:recyclerview-v7:27.1.1'
    implementation 'com.android.volley:volley:1.0.0'
    // google
    implementation 'com.google.firebase:firebase-core:15.0.2'
    implementation 'com.google.firebase:firebase-messaging:15.0.2'
    //external libs
    implementation 'com.github.devlight:infinitecycleviewpager:1.0.2'
}
apply plugin: 'com.google.gms.google-services'

Answer 1

firebase-common looks for a particular string resource, "google_app_id", in FirebaseApp.initializeApp(Context) which in my case doesn't seem to exist.

(com.google.firebase:firebase-common@@16.0.4:301)
    StringResourceValueReader reader = new StringResourceValueReader(context);
    String applicationId = reader.getString("google_app_id");

I imagine this is supposed to be populated by google-services.json. Unsure of a solution at this time.
