激励广告

激励广告允许您向与视频广告、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

Google 移动广告 SDK 19.7.0 或更高版本。
完成入门指南。

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测试专用广告单元 ID：

/21775744923/example/rewarded

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。只需确保您会在发布应用前用自己的广告单元 ID 替换该测试广告单元 ID 即可。

如需详细了解移动广告 SDK 的测试广告如何运作，请参阅测试广告。

加载激励广告对象

针对 RewardedAd 类调用静态 load() 方法并传入 RewardedAdLoadCallback 可加载激励广告。这通常是在 Activity 的 onCreate() 方法中完成的。请注意，与其他广告格式加载回调一样，RewardedAdLoadCallback 会利用 LoadAdError 提供较高保真度的错误详情。

Java

import com.google.android.gms.ads.rewarded.RewardedAd;

public class MainActivity extends Activity {
  private RewardedAd rewardedAd;
  private final String TAG = "MainActivity";

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    AdManagerAdRequest adRequest = new AdManagerAdRequest.Builder().build();
    RewardedAd.load(this, "/21775744923/example/rewarded",
      adRequest, new RewardedAdLoadCallback() {
        @Override
        public void onAdFailedToLoad(@NonNull LoadAdError loadAdError) {
          // Handle the error.
          Log.d(TAG, loadAdError.toString());
          rewardedAd = null;
        }

        @Override
        public void onAdLoaded(@NonNull RewardedAd ad) {
          rewardedAd = ad;
          Log.d(TAG, "Ad was loaded.");
        }
    });
  }
}

Kotlin

class MainActivity : AppCompatActivity() {

  private var rewardedAd: RewardedAd? = null
  private final var TAG = "MainActivity"

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    var adRequest = AdManagerAdRequest.Builder().build()
    RewardedAd.load(this,"/21775744923/example/rewarded", adRequest, object : RewardedAdLoadCallback() {
      override fun onAdFailedToLoad(adError: LoadAdError) {
        Log.d(TAG, adError?.toString())
        rewardedAd = null
      }

      override fun onAdLoaded(ad: RewardedAd) {
        Log.d(TAG, "Ad was loaded.")
        rewardedAd = ad
       }
    })
  }
}

设置 FullScreenContentCallback

FullScreenContentCallback 处理与展示 RewardedAd 相关的事件。在展示 RewardedAd 之前，请务必按如下方式设置回调：

Java

rewardedAd.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.");
    rewardedAd = null;
  }

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

Kotlin

rewardedAd?.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.
    // Set the ad reference to null so you don't show the ad a second time.
    Log.d(TAG, "Ad dismissed fullscreen content.")
    rewardedAd = null
  }

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

展示广告

展示激励广告时，您将使用 OnUserEarnedRewardListener 对象处理奖励事件。

Java

if (rewardedAd != null) {
  Activity activityContext = MainActivity.this;
  rewardedAd.show(activityContext, new OnUserEarnedRewardListener() {
    @Override
    public void onUserEarnedReward(@NonNull RewardItem rewardItem) {
      // Handle the reward.
      Log.d(TAG, "The user earned the reward.");
      int rewardAmount = rewardItem.getAmount();
      String rewardType = rewardItem.getType();
    }
  });
} else {
  Log.d(TAG, "The rewarded ad wasn't ready yet.");
}

Kotlin

rewardedAd?.let { ad ->
  ad.show(this, OnUserEarnedRewardListener { rewardItem ->
    // Handle the reward.
    val rewardAmount = rewardItem.amount
    val rewardType = rewardItem.type
    Log.d(TAG, "User earned the reward.")
  })
} ?: run {
  Log.d(TAG, "The rewarded ad wasn't ready yet.")
}

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 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 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 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，回调顺序取决于第三方广告联盟 SDK 的实现方式。对于为单个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()。
