獎勵廣告

選取平台： Android iOS Unity Flutter

透過獎勵廣告，您可以在使用者與影片廣告/可試玩廣告互動或填寫問卷調查後，提供應用程式內商品做為獎勵。

必備條件

  • Google Mobile Ads SDK 19.7.0 以上版本。
  • 完成入門指南的步驟。

請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，否則可能導致帳戶遭停權。

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

/21775744923/example/rewarded

這類 ID 經特別設定，可針對每個請求傳回測試廣告。您可在編寫程式碼、測試及偵錯時，將其用於自己的應用程式。發布應用程式前，請務必將這類 ID 替換為自己的廣告單元 ID。

請參閱「測試廣告」，進一步瞭解 Google Mobile Ads SDK 測試廣告的運作方式。

載入獎勵廣告物件

如要載入獎勵廣告，請在 RewardedAd 類別中呼叫靜態 load() 方法，並傳入 RewardedAdLoadCallback。這通常是在 Activity 的 onCreate() 方法中完成。請注意，與其他格式載入回呼相似，RewardedAdLoadCallback 會運用 LoadAdError 提供更高保真的錯誤詳情。

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

將 AD_UNIT_ID 替換為廣告單元 ID。

設定 FullScreenContentCallback

FullScreenContentCallback 會處理與顯示 RewardedAd 相關的事件。顯示 RewardedAd 前，請務必設定回呼，如下所示：

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

顯示廣告

顯示獎勵廣告時，您可以使用 OnUserEarnedRewardListener 物件處理獎勵事件。

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

[選用] 驗證伺服器端驗證 (SSV) 回呼

伺服器端驗證回呼時，如果應用程式需要額外資料，請使用獎勵廣告的自訂資料功能。在獎勵廣告物件設定的字串值，會傳遞至 SSV 回呼的 custom_data 查詢參數。如未設定自訂資料值，SSV 回呼就不會出現 custom_data 查詢參數值。

請參考以下程式碼範例，瞭解如何在請求廣告前，於獎勵廣告物件設定自訂資料：

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

將 SAMPLE_CUSTOM_DATA_STRING 替換成自訂資料。

如要設定自訂獎勵字串，請務必在廣告顯示前完成。
