    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
        // Initialize admob (AdMob app ID)
        MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713");
 
        adView = findViewById(R.id.adView);
