Google Maps API displaying grey screen instead of map view on Android

I am trying to display the Google map on Android. When I load the activity i get a grey screen with the Google logo displayed in the bottom left corner. This happens using the virtual emulator and on a real device too. I have tried using a different Api key but get the same problem. I am using the Map activity provided by Android studio.

build.gradle(Module:app)

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 28
    defaultConfig {

        minSdkVersion 19
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        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-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    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'

    implementation 'com.google.android.gms:play-services-maps:16.0.0'
    implementation 'com.google.android.gms:play-services-location:16.0.0'

}

try to change the hardware-sensors to not required:

<uses-feature
    android:name="android.hardware.sensor.stepcounter"
    android:required="false"/>

<uses-feature
    android:name="android.hardware.sensor.stepdetector"
    android:required="false"/>

and also this permission is not required anymore, for years:

<uses-permission android:name="com.google.android.providers.gfs.permission.READ_GSERVICES" />

and the problem actually stems from:

apply plugin: "com.google.gms.google-services"

which has to be moved to the very bottom of the file.
