激励广告

请选择平台： Android（Beta 版） 新 Android iOS Unity Flutter

激励广告可让您在用户与视频广告、试玩广告和调查问卷互动后，向其发放应用内奖励。

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暂停。

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：

/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。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 Mobile Ads SDK 测试广告，请参阅启用测试广告。

加载激励广告对象

通过调用 RewardedAd 类的静态 load() 方法并传入 RewardedAdLoadCallback，即可加载激励广告。这通常是在 Activity 的 onCreate() 方法中完成的。请注意，与其他广告格式的加载回调一样，RewardedAdLoadCallback 会利用 LoadAdError 提供更详细且更准确的错误信息。

Java

RewardedAd.load(
    this,
    "AD_UNIT_ID",
    new AdManagerAdRequest.Builder().build(),
    new RewardedAdLoadCallback() {
      @Override
      public void onAdLoaded(@NonNull RewardedAd rewardedAd) {
        Log.d(TAG, "Ad was loaded.");
        MainActivity.this.rewardedAd = rewardedAd;
      }

      @Override
      public void onAdFailedToLoad(@NonNull LoadAdError loadAdError) {
        Log.d(TAG, loadAdError.getMessage());
        rewardedAd = null;
      }
    });
MainActivity.java

Kotlin

RewardedAd.load(
  this,
  "AD_UNIT_ID",
  AdManagerAdRequest.Builder().build(),
  object : RewardedAdLoadCallback() {
    override fun onAdLoaded(ad: RewardedAd) {
      Log.d(TAG, "Ad was loaded.")
      rewardedAd = ad
    }

    override fun onAdFailedToLoad(adError: LoadAdError) {
      Log.d(TAG, adError.message)
      rewardedAd = null
    }
  },
)
MainActivity.kt

请将 AD_UNIT_ID 替换为您实际的广告单元 ID。

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 onAdDismissedFullScreenContent() {
        // Called when fullscreen content is dismissed.
        Log.d(TAG, "Ad was dismissed.");
        // Don't forget to set the ad reference to null so you
        // don't show the ad a second time.
        rewardedAd = null;
      }

      @Override
      public void onAdFailedToShowFullScreenContent(AdError adError) {
        // Called when fullscreen content failed to show.
        Log.d(TAG, "Ad failed to show.");
        // Don't forget to set the ad reference to null so you
        // don't show the ad a second time.
        rewardedAd = null;
      }

      @Override
      public void onAdShowedFullScreenContent() {
        // Called when fullscreen content is shown.
        Log.d(TAG, "Ad showed fullscreen content.");
      }

      @Override
      public void onAdImpression() {
        // Called when an impression is recorded for an ad.
        Log.d(TAG, "Ad recorded an impression.");
      }

      @Override
      public void onAdClicked() {
        // Called when an ad is clicked.
        Log.d(TAG, "Ad was clicked.");
      }
    });
MainActivity.java

Kotlin

rewardedAd?.fullScreenContentCallback =
  object : FullScreenContentCallback() {
    override fun onAdDismissedFullScreenContent() {
      // Called when fullscreen content is dismissed.
      Log.d(TAG, "Ad was dismissed.")
      // Don't forget to set the ad reference to null so you
      // don't show the ad a second time.
      rewardedAd = null
    }

    override fun onAdFailedToShowFullScreenContent(adError: AdError) {
      // Called when fullscreen content failed to show.
      Log.d(TAG, "Ad failed to show.")
      // Don't forget to set the ad reference to null so you
      // don't show the ad a second time.
      rewardedAd = null
    }

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

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

    override fun onAdClicked() {
      // Called when an ad is clicked.
      Log.d(TAG, "Ad was clicked.")
    }
  }
MainActivity.kt

展示广告

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

Java

rewardedAd.show(
    MainActivity.this,
    new OnUserEarnedRewardListener() {
      @Override
      public void onUserEarnedReward(@NonNull RewardItem rewardItem) {
        Log.d(TAG, "User earned the reward.");
        // Handle the reward.
      }
    });
MainActivity.java

Kotlin

rewardedAd?.show(
  this,
  OnUserEarnedRewardListener { rewardItem ->
    Log.d(TAG, "User earned the reward.")
    // Handle the reward.
    val rewardAmount = rewardItem.amount
    val rewardType = rewardItem.type
  },
)
MainActivity.kt

[可选] 验证服务器端验证 (SSV) 回调

对于在服务器端验证回调中需要额外数据的应用，应使用激励广告的自定义数据功能。为激励广告对象设定的任何字符串值都将传递给 SSV 回调的 custom_data 查询参数。如果未设置自定义数据值，custom_data 查询参数值不会出现在 SSV 回调中。

以下代码示例演示了如何在请求广告之前为激励广告对象设定自定义数据。

Java

RewardedAd.load(
    context,
    AD_UNIT_ID,
    new AdRequest.Builder().build(),
    new RewardedAdLoadCallback() {
      @Override
      public void onAdLoaded(RewardedAd ad) {
        rewardedAd = ad;
        ServerSideVerificationOptions options =
            new ServerSideVerificationOptions.Builder()
                .setCustomData("SAMPLE_CUSTOM_DATA_STRING")
                .build();
        rewardedAd.setServerSideVerificationOptions(options);
      }
    });
RewardedAdSnippets.java

Kotlin

RewardedAd.load(
  context,
  AD_UNIT_ID,
  AdRequest.Builder().build(),
  object : RewardedAdLoadCallback() {
    override fun onAdLoaded(ad: RewardedAd) {
      rewardedAd = ad
      val options =
        ServerSideVerificationOptions.Builder().setCustomData("SAMPLE_CUSTOM_DATA_STRING").build()
      rewardedAd?.setServerSideVerificationOptions(options)
    }
  },
)
RewardedAdSnippets.kt

将 SAMPLE_CUSTOM_DATA_STRING 替换为您的自定义数据。

如果您要设置自定义奖励字符串，则必须在展示广告之前设置。

常见问题解答

初始化调用有超时限制吗？
10 秒后，即使中介广告联盟仍未完成初始化，Google Mobile Ads SDK 还是会调用 OnInitializationCompleteListener。
如果我收到初始化回调时，某些中介广告联盟仍未就绪，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 Mobile Ads 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，它仍可在该会话中处理后续广告请求。

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。

如何查看特定中介广告联盟未就绪的原因？

AdapterStatus.getDescription() 描述了适配器尚未准备好处理广告请求的原因。

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

对于 Google 广告，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。如果广告联盟 SDK 只提供一个包含奖励信息的关闭回调，中介适配器会在调用 onAdDismissedFullScreenContent() 之前调用 onUserEarnedReward()。
