插頁式獎勵廣告

插頁式獎勵廣告是一種獎勵廣告格式，會在應用程式自然轉換時，自動顯示廣告並給予使用者獎勵。不同於獎勵廣告，插頁式獎勵廣告不需等使用者選擇觀看即可放送。

必要條件

一律使用測試廣告進行測試

建構及測試應用程式時，請務必使用測試廣告，而非實際的正式廣告。否則帳戶可能會遭到停權。

如要載入測試廣告，最簡單的方法是使用 Android 插頁式獎勵廣告專用的測試廣告單元 ID：

ca-app-pub-3940256099942544/5354046379

這個 ID 經過特別設定，每次請求都會傳回測試廣告。在編寫程式碼、測試及偵錯階段，您可以在應用程式中自由使用，發布應用程式前，請務必用自己的廣告單元 ID 替換這類 ID。

如要進一步瞭解 Google Mobile Ads SDK (Beta 版) 測試廣告的運作方式，請參閱「測試廣告」。

載入廣告

如要載入插頁式獎勵廣告，請呼叫 RewardedInterstitialAd 的靜態 load() 方法，並傳遞 AdLoadCallback<RewardedInterstitialAd> 來接收成功載入的廣告，或處理可能發生的錯誤。

Kotlin

import com.google.android.libraries.ads.mobile.sdk.common.AdLoadCallback
import com.google.android.libraries.ads.mobile.sdk.common.AdRequest
import com.google.android.libraries.ads.mobile.sdk.common.FullScreenContentError
import com.google.android.libraries.ads.mobile.sdk.common.LoadAdError
import com.google.android.libraries.ads.mobile.sdk.rewardedinterstitial.RewardedInterstitialAd
import com.google.android.libraries.ads.mobile.sdk.rewardedinterstitial.RewardedInterstitialAdEventCallback
import com.google.android.libraries.ads.mobile.sdk.MobileAds

class RewardedInterstitialActivity : Activity() {
  private var rewardedInterstitialAd: RewardedInterstitialAd? = null

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    // Load ads after you initialize Google Mobile Ads SDK (beta).
    RewardedInterstitialAd.load(
      AdRequest.Builder(AD_UNIT_ID).build(),
      object : AdLoadCallback<RewardedInterstitialAd> {
        override fun onAdLoaded(ad: RewardedInterstitialAd) {
          // Rewarded interstitial ad loaded.
          rewardedInterstitialAd = ad
        }

        override fun onAdFailedToLoad(adError: LoadAdError) {
          // Rewarded interstitial ad failed to load.
          rewardedInterstitialAd = null
        }
      },
    )
  }

  companion object {
    // Sample rewarded interstitial ad unit ID.
    const val AD_UNIT_ID = "ca-app-pub-3940256099942544/5354046379"
  }
}

Java

import com.google.android.libraries.ads.mobile.sdk.common.AdLoadCallback;
import com.google.android.libraries.ads.mobile.sdk.common.AdRequest;
import com.google.android.libraries.ads.mobile.sdk.common.FullScreenContentError;
import com.google.android.libraries.ads.mobile.sdk.common.LoadAdError;
import com.google.android.libraries.ads.mobile.sdk.rewardedinterstitial.RewardedInterstitialAd;
import com.google.android.libraries.ads.mobile.sdk.rewardedinterstitial.RewardedInterstitialAdEventCallback;
import com.google.android.libraries.ads.mobile.sdk.MobileAds;

class RewardedActivity extends Activity {
  // Sample rewarded interstitial ad unit ID.
  private static final String AD_UNIT_ID = "ca-app-pub-3940256099942544/5354046379";
  private RewardedInterstitialAd rewardedInterstitialAd;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Load ads after you initialize Google Mobile Ads SDK (beta).
    RewardedInterstitialAd.load(
        new AdRequest.Builder(AD_UNIT_ID).build(),
        new AdLoadCallback<RewardedInterstitialAd>() {
          @Override
          public void onAdLoaded(@NonNull RewardedInterstitialAd rewardedInterstitialAd) {
            // Rewarded interstitial ad loaded.
            AdLoadCallback.super.onAdLoaded(rewardedInterstitialAd);
            RewardedActivity.this.rewardedInterstitialAd = rewardedInterstitialAd;
          }

          @Override
          public void onAdFailedToLoad(@NonNull LoadAdError adError) {
            // Rewarded interstitial ad failed to load.
            AdLoadCallback.super.onAdFailedToLoad(adError);
            rewardedInterstitialAd = null;
          }
        }
    );
  }
}

設定 RewardedInterstitialAdEventCallback

RewardedInterstitialAdEventCallback 會處理與顯示 RewardedInterstitialAd 相關的事件，顯示插頁式獎勵廣告前，請務必設定回呼：

Kotlin

// Listen for ad events.
rewardedInterstitialAd?.adEventCallback =
  object : RewardedInterstitialAdEventCallback {
    override fun onAdShowedFullScreenContent() {
      // Rewarded interstitial ad did show.
    }

    override fun onAdDismissedFullScreenContent() {
      // Rewarded interstitial ad did dismiss.
      rewardedInterstitialAd = null
    }

    override fun onAdFailedToShowFullScreenContent(
      fullScreenContentError: FullScreenContentError
    ) {
      // Rewarded interstitial ad failed to show.
      rewardedInterstitialAd = null
    }

    override fun onAdImpression() {
      // Rewarded interstitial ad did record an impression.
    }

    override fun onAdClicked() {
      // Rewarded interstitial ad did record a click.
    }
  }

Java

// Listen for ad events.
rewardedInterstitialAd.setAdEventCallback(
    new RewardedInterstitialAdEventCallback() {
      @Override
      public void onAdShowedFullScreenContent() {
        // Rewarded interstitial ad did show.
        RewardedInterstitialAdEventCallback.super.onAdShowedFullScreenContent();
      }

      @Override
      public void onAdDismissedFullScreenContent() {
        // Rewarded interstitial ad did dismiss.
        RewardedInterstitialAdEventCallback.super.onAdDismissedFullScreenContent();
        rewardedInterstitialAd = null;
      }

      @Override
      public void onAdFailedToShowFullScreenContent(
          @NonNull FullScreenContentError fullScreenContentError) {
        // Rewarded interstitial ad failed to show.
        RewardedInterstitialAdEventCallback.super.onAdFailedToShowFullScreenContent(
            fullScreenContentError);
        rewardedInterstitialAd = null;
      }

      @Override
      public void onAdImpression() {
        // Rewarded interstitial ad did record an impression.
        RewardedInterstitialAdEventCallback.super.onAdImpression();
      }

      @Override
      public void onAdClicked() {
        // Rewarded interstitial ad did record a click.
        RewardedInterstitialAdEventCallback.super.onAdClicked();
      }
    }
);

顯示廣告

請使用 show() 方法顯示插頁式獎勵廣告，並透過 OnUserEarnedRewardListener 物件來處理獎勵事件。

Kotlin

// Show the ad.
rewardedInterstitialAd?.show(
  this@RewardedActivity,
  object : OnUserEarnedRewardListener {
    override fun onUserEarnedReward(rewardItem: RewardItem) {
      // User earned the reward.
      val rewardAmount = rewardItem.amount
      val rewardType = rewardItem.type
    }
  },
)

Java

// Show the ad.
rewardedInterstitialAd.show(
    RewardedActivity.this,
    new OnUserEarnedRewardListener() {
      @Override
      public void onUserEarnedReward(@NonNull RewardItem rewardItem) {
        // User earned the reward.
        int rewardAmount = rewardItem.getAmount();
        String rewardType = rewardItem.getType();
    }
});
