Adding Admob to libgdx

Add AdMob Ads without Firebase :

  1. Put these lines inside build.gradle of android module.

    dependencies {
    
        compile 'com.google.android.gms:play-services-ads:10.2.4'
    }
    
  2. Add permission in AndoidManifest.xml file

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    

    Inside <application tag add Activity if want to use Interstitial Ads

    <meta-data android:name="com.google.android.gms.version"
               android:value="@integer/google_play_services_version" />
    
    <activity android:name="com.google.android.gms.ads.AdActivity"
              android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
              android:theme="@android:style/Theme.Translucent" />
    
  3. AndroidLauncher class.

    public class AndroidLauncher extends AndroidApplication {
    
    private static final String adUnitId="ca-app-pub-xxxxxxxxxxxxxxxxxxxxx";
    private AdView adView;
    
    @Override
    protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
    
        RelativeLayout layout = new RelativeLayout(this);
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
        layout.setLayoutParams(params);
    
        View gameView=initializeForView(new MyGdxGame(), config);
    
        RelativeLayout.LayoutParams gameViewParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        gameViewParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
        gameViewParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
    
        gameView.setLayoutParams(gameViewParams);
        layout.addView(gameView);
    
        adView = new AdView(this);
        adView.setAdSize(AdSize.BANNER);
        adView.setAdUnitId(adUnitId);
    
        AdRequest.Builder adRequestBuilder = new AdRequest.Builder();
        adRequestBuilder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);
        adView.loadAd(adRequestBuilder.build());
    
        RelativeLayout.LayoutParams topParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        topParams.addRule(RelativeLayout.ALIGN_PARENT_TOP,RelativeLayout.TRUE);
        topParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
        layout.addView(adView, topParams);
        adView.setBackgroundColor(android.graphics.Color.TRANSPARENT);
    
        setContentView(layout);
    }
    
    @Override
    protected void onResume() {
        super.onResume();
        adView.resume();
    }
    
    @Override
    protected void onPause() {
        super.onPause();
        adView.pause();
    }
    
    @Override
    protected void onDestroy() {
        super.onDestroy();
        adView.destroy();
    }
    }
