Crear anuncio Admob Interstitial en Android

Tiempo de lectura: 2 minutos

Hoy vamos a aprender cómo podemos implementar un anuncio Interstitial en Android con Java.

Primero implementaremos en nuestro build.gradle:

    implementation 'com.google.android.gms:play-services-ads:23.0.0'

Después tenemos que inicializar los anuncios en nuestro MainActivity:

    MobileAds.initialize(
        this,
        new OnInitializationCompleteListener() {
          @Override
          public void onInitializationComplete(InitializationStatus initializationStatus) {}
        });

Y añadimos en el manifest (debajo de </application>)

    <meta-data
        android:name="com.google.android.gms.ads.AD_MANAGER_APP"
        android:value="true" />

Y también dentro de <application> </application>

        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="TU_ID_APLICACION_ADMOB" />

Cambia TU_ID_APLICACION_ADMOB por el id de tu APP de Admob.

Ahora vamos a crear nuestro anuncio interstitial:

    private InterstitialAd mInterstitialAd;

public void cargarAnuncioVideo() {
        try {
            AdRequest adRequest = new AdRequest.Builder().build();

            InterstitialAd.load(this, "tu_id_anuncio_admob_video", adRequest,
                    new InterstitialAdLoadCallback() {
                        @Override
                        public void onAdLoaded(@NonNull InterstitialAd interstitialAd) {
                            // The mInterstitialAd reference will be null until
                            // an ad is loaded.
                            mInterstitialAd = interstitialAd;
                            Log.i("TAG", "onAdLoaded");
                            if (mInterstitialAd != null) {
                                mInterstitialAd.show((Activity) getApplicationContext());
                            } else {
                                Log.d("TAG", "The interstitial ad wasn't ready yet.");
                            }

                             mInterstitialAd.setFullScreenContentCallback(new FullScreenContentCallback() {
                @Override
                public void onAdClicked() {
                    // Called when a click is recorded for an ad.
                    Log.d("TAG", "Ad was clicked.");
                }

                @Override
                public void onAdDismissedFullScreenContent() {
                    // Called when ad is dismissed.
                     //Anuncio cargado, puedes realizar la accion que quieras
                    // Set the ad reference to null so you don't show the ad a second time.
                    Log.d("TAG", "Ad dismissed fullscreen content.");
                    mInterstitialAd = null;
                   
                }

                @Override
                public void onAdFailedToShowFullScreenContent(AdError adError) {
                    // Called when ad fails to show.
                    Log.e("TAG", "Ad failed to show fullscreen content.");
                    mInterstitialAd = null;
                }

                @Override
                public void onAdImpression() {
                    // Called when an impression is recorded for an ad.
                    Log.d("TAG", "Ad recorded an impression.");
                }

                @Override
                public void onAdShowedFullScreenContent() {
                  
                }
            });

                        }

                        @Override
                        public void onAdFailedToLoad(@NonNull LoadAdError loadAdError) {
                            // Handle the error
                            Log.d("anuncio", loadAdError.toString());
                            mInterstitialAd = null;
                        
                         
                        }
                    });
           

        } catch (Exception e) {
            Log.e("anuncio", "falla1");
        }
    }

En la parte de

  public void onAdDismissedFullScreenContent() {

//Anuncio cargado, puedes realizar la accion que quieras puedes indicar la accion que quieras realizar una vez cargado el anuncio.

Recuerda indicar tu id de anuncio aqui: InterstitialAd.load(this, «tu_id_anuncio_admob_video», adRequest,
