Android Error: Firebase Database component is not present

Question

I have integrated a firebase real-time database in my app and I am getting a

java.lang.NullPointerException: Firebase Database component is not present

when I try to create an instance of a firebase database with the code below,

FirebaseApp firebaseApp = FirebaseApp.initializeApp(this);
mFirebaseInstance = FirebaseDatabase.getInstance(firebaseApp);

I also tried this,

mFirebaseInstance = FirebaseDatabase.getInstance();

Every time getting error Firebase Database component is not present.

Below is project gradle file code:

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        //classpath 'com.google.gms:google-services:4.2.0'
        classpath 'com.google.gms:google-services:3.2.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects{
    repositories {
    mavenCentral()
    google()
    jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Below are dependency which I have added Dependencies :

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    //implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'androidx.appcompat:appcompat:1.0.0'

    // Needed to fix a dependency conflict with FirebaseUI'
    implementation 'androidx.arch.core:core-runtime:2.0.1'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    androidTestImplementation 'androidx.test:rules:1.2.0'

}
apply plugin: 'com.google.gms.google-services'

I also tried to change the database dependency version, change class path and update google-services.json file but I am still facing the same error.
