Annunci interstitial

Gli annunci interstitial sono annunci a schermo intero che coprono l'interfaccia dell'app host. In genere vengono visualizzati in punti di transizione naturali nel flusso di un'app, ad esempio tra un'attività e l'altra o durante la pausa tra i livelli di un gioco. Quando un'app mostra un annuncio interstitial, l'utente può scegliere di toccarlo per continuare alla destinazione o chiuderlo e tornare all'app. Leggi uno dei nostri case study.

Questa guida spiega come integrare gli annunci in interrompimento in un'app Android.

Prerequisiti

SDK Google Mobile Ads 19.7.0 o versioni successive.
Completa la Guida introduttiva.

Esegui sempre test con annunci di prova

Quando crei e testi le tue app, assicurati di utilizzare annunci di prova anziché annunci pubblicati e in produzione. In caso contrario, il tuo account potrebbe essere sospeso.

Il modo più semplice per caricare gli annunci di prova è utilizzare il nostro ID unità pubblicitaria di prova dedicato per gli annunci interstitial Android:

ca-app-pub-3940256099942544/1033173712

È stato configurato appositamente per restituire annunci di prova per ogni richiesta e puoi usarlo nelle tue app durante la programmazione, i test e il debug. Assicurati solo di sostituirlo con il tuo ID unità pubblicitaria prima di pubblicare l'app.

Per ulteriori informazioni sul funzionamento degli annunci di prova dell'SDK Mobile Ads, consulta Annunci di prova.

Carica un annuncio

Per caricare un annuncio interstitial, chiama il metodo InterstitialAd statico load() e passa un InterstitialAdLoadCallback per ricevere l'annuncio caricato o eventuali errori. Tieni presente che, come altri callback di caricamento del formato, InterstitialAdLoadCallback sfrutta LoadAdError per fornire dettagli sugli errori con una maggiore fedeltà.

JavaKotlin

import com.google.android.gms.ads.interstitial.InterstitialAd;
import com.google.android.gms.ads.interstitial.InterstitialAdLoadCallback;

public class MainActivity extends Activity {

  private InterstitialAd mInterstitialAd;
  private static final String TAG = "MainActivity";

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    AdRequest adRequest = new AdRequest.Builder().build();

    InterstitialAd.load(this,"ca-app-pub-3940256099942544/1033173712", 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");
      }

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

import com.google.android.gms.ads.interstitial.InterstitialAd;
import com.google.android.gms.ads.interstitial.InterstitialAdLoadCallback;

class MainActivity : AppCompatActivity() {

  private var mInterstitialAd: InterstitialAd? = null
  private final val TAG = "MainActivity"

    override fun onCreate(savedInstanceState: Bundle?) {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main)

      val adRequest = AdRequest.Builder().build()

      InterstitialAd.load(this,"ca-app-pub-3940256099942544/1033173712", adRequest, object : InterstitialAdLoadCallback() {
        override fun onAdFailedToLoad(adError: LoadAdError) {
          Log.d(TAG, adError?.toString())
          mInterstitialAd = null
        }

        override fun onAdLoaded(interstitialAd: InterstitialAd) {
          Log.d(TAG, 'Ad was loaded.')
          mInterstitialAd = interstitialAd
        }
      })
    }
}

Imposta FullScreenContentCallback

FullScreenContentCallback gestisce gli eventi relativi alla visualizzazione del tuo InterstitialAd. Prima di mostrare InterstitialAd, assicurati di impostare il callback:

JavaKotlin

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.
    // 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() {
    // Called when ad is shown.
    Log.d(TAG, "Ad showed fullscreen content.");
  }
});

mInterstitialAd?.fullScreenContentCallback = object: FullScreenContentCallback() {
  override fun onAdClicked() {
    // Called when a click is recorded for an ad.
    Log.d(TAG, "Ad was clicked.")
  }

  override fun onAdDismissedFullScreenContent() {
    // Called when ad is dismissed.
    Log.d(TAG, "Ad dismissed fullscreen content.")
    mInterstitialAd = null
  }

  override fun onAdFailedToShowFullScreenContent(adError: AdError?) {
    // Called when ad fails to show.
    Log.e(TAG, "Ad failed to show fullscreen content.")
    mInterstitialAd = null
  }

  override fun onAdImpression() {
    // Called when an impression is recorded for an ad.
    Log.d(TAG, "Ad recorded an impression.")
  }

  override fun onAdShowedFullScreenContent() {
    // Called when ad is shown.
    Log.d(TAG, "Ad showed fullscreen content.")
  }
}

Mostrare l'annuncio

Gli annunci interstitial devono essere visualizzati durante le pause naturali nel flusso di un'app. Un buon esempio è la pausa tra i livelli di un gioco o dopo che l'utente ha completato un'attività. Per mostrare un annuncio interstitial, utilizza il metodo show().

JavaKotlin

if (mInterstitialAd != null) {
  mInterstitialAd.show(MyActivity.this);
} else {
  Log.d("TAG", "The interstitial ad wasn't ready yet.");
}

if (mInterstitialAd != null) {
  mInterstitialAd?.show(this)
} else {
  Log.d("TAG", "The interstitial ad wasn't ready yet.")
}

Alcune best practice

Valuta se gli annunci interstitial sono il tipo di annuncio giusto per la tua app.: Gli annunci interstitial funzionano al meglio nelle app con punti di transizione naturali. La conclusione di un'attività all'interno di un'app, ad esempio la condivisione di un'immagine o il completamento di un livello di un gioco, crea un punto di questo tipo. Assicurati di considerare in quali punti del flusso di lavoro della tua app mostrerai gli annunci interstitial e in che modo l'utente è più propenso a rispondere.
Ricordati di mettere in pausa l'azione quando viene visualizzato un annuncio interstitial.: Esistono diversi tipi di annunci interstitial: di testo, illustrati, video e altri ancora. È importante assicurarsi che, quando l'app mostra un annuncio interstitial, sospenda anche l'utilizzo di alcune risorse per consentire all'annuncio di sfruttarle. Ad esempio, quando effettui la chiamata per visualizzare un annunci interstitial, assicurati di mettere in pausa l'output audio prodotto dalla tua app.
Assicurati che il tempo di caricamento sia adeguato.: Proprio come è importante assicurarsi di mostrare gli annunci interstitial al momento opportuno, è importante anche assicurarsi che l'utente non debba attendere il loro caricamento. Se carichi l'annuncio in anticipo chiamando load() prima di chiamare show(), puoi assicurarti che la tua app abbia un annuncio interstitial completamente caricato al momento di visualizzarlo.
Non inondare l'utente di annunci.: Anche se aumentare la frequenza degli annunci interstitial nella tua app può sembrare un ottimo modo per aumentare le entrate, può anche peggiorare l'esperienza utente e ridurre le percentuali di clic. Assicurati che le interruzioni non siano così frequenti da impedire agli utenti di utilizzare la tua app.
