激励广告

通过激励广告，您可以向与视频广告、试玩广告和调查问卷进行互动的用户奖励应用内商品。

前提条件

通读入门指南。

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 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-3940256099942544/5224354917

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

要加载激励广告，请调用 RewardedAd 静态 load() 方法并传入 AdLoadCallback<RewardedAd>，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.rewarded.RewardedAd
import com.google.android.libraries.ads.mobile.sdk.rewarded.RewardedAdEventCallback
import com.google.android.libraries.ads.mobile.sdk.MobileAds

class RewardedActivity : Activity() {
  private var rewardedAd: RewardedAd? = null

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

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

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

  companion object {
    // Sample rewarded ad unit ID.
    const val AD_UNIT_ID = "ca-app-pub-3940256099942544/5224354917"
  }
}

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.rewarded.RewardedAd;
import com.google.android.libraries.ads.mobile.sdk.rewarded.RewardedAdEventCallback;
import com.google.android.libraries.ads.mobile.sdk.MobileAds;

class RewardedActivity extends Activity {
  // Sample rewarded ad unit ID.
  private static final String AD_UNIT_ID = "ca-app-pub-3940256099942544/5224354917";
  private RewardedAd rewardedAd;

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

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

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

设置 RewardedAdEventCallback

RewardedAdEventCallback 负责处理与展示 RewardedAd 相关的事件。在展示激励广告之前，请务必按如下方式设置回调：

Kotlin

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

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

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

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

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

Java

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

      @Override
      public void onAdDismissedFullScreenContent() {
        // Rewarded ad did dismiss.
        RewardedAdEventCallback.super.onAdDismissedFullScreenContent();
        rewardedAd = null;
      }

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

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

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

展示广告

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

Kotlin

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

常见问题解答

初始化调用是否会超时？

10 秒后，即使中介广告联盟仍未完成初始化，Google 移动广告 SDK（Beta 版）还是会调用 OnInitializationCompleteListener。

在获得初始化回调时，如果某些中介广告联盟尚未就绪，该怎么办？

我们建议您在 OnInitializationCompleteListener 的回调中加载广告。即使中介广告联盟尚未就绪，Google 移动广告 SDK（Beta 版）仍会向该广告联盟请求广告。因此，如果中介广告联盟在超时后完成初始化，它仍然可以在该会话中为将来的广告请求提供服务。

您可以通过调用 MobileAds.getInitializationStatus() 继续在整个应用会话中轮询所有适配器的初始化状态。

如何找出特定中介广告联盟未准备就绪的原因？

AdapterStatus.getDescription() 描述了适配器未准备好为广告请求提供服务的原因。

系统是否始终会在调用 onAdDismissedFullScreenContent() 回调之前调用 onUserEarnedReward() 回调？

对于 Google Ads，所有 onUserEarnedReward() 调用都发生在 onAdDismissedFullScreenContent() 调用之前。对于通过中介投放的广告，由第三方广告联盟 SDK 的实现情况决定回调顺序。对于为单次关闭回调提供奖励信息的广告联盟 SDK，中介适配器会在调用 onAdDismissedFullScreenContent() 之前调用 onUserEarnedReward()。
