插页式激励广告

插页式激励广告是一种激励用户的广告格式，采用这种格式时，您可以通过在应用中的自然过渡点自动展示的广告向用户提供奖励。与激励广告不同，用户无需自行选择即可观看插页式激励广告。

前提条件

务必用测试广告进行测试

在构建和测试应用时，请确保使用的是测试广告，而不是实际投放的广告。否则，可能会导致您的账号被中止。

对于 Android 插页式激励广告，加载测试广告最简便的方法就是使用下面的专用测试广告单元 ID：

ca-app-pub-3940256099942544/5354046379

该测试广告单元 ID 已经过专门配置，可确保每个请求返回的都是测试广告。您可以在自己应用的编码、测试和调试过程中随意使用该测试广告单元 ID。需要注意的一点是，请务必在发布应用前用您的广告单元 ID 替换该测试广告单元 ID。

如需详细了解 Google 移动广告 SDK（Beta 版）的测试广告如何运作，请参阅测试广告。

加载广告

要加载插页式激励广告，请调用 RewardedInterstitialAd 静态 load() 方法并传入 AdLoadCallback<RewardedInterstitialAd>，以接收加载的广告或任何可能的错误。

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;
          }
        }
    );
  }
}

设置 RewardedInterstitialAdEventCallback

RewardedInterstitialAdEventCallback 处理与展示 RewardedInterstitialAd 相关的事件。在展示插页式激励广告之前，请务必设置回调：

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();
      }
    }
);

展示广告

如需展示插页式激励广告，请使用 show() 方法。使用 OnUserEarnedRewardListener 对象处理奖励事件。

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();
    }
});
