插頁式獎勵廣告 (Beta 版)

選取平台： Android iOS Unity Flutter

插頁式獎勵廣告是一種獎勵廣告格式，您可在應用程式自然轉換時自動顯示這類廣告，向使用者提供獎勵。與獎勵廣告不同的是，插頁式獎勵廣告不需要等使用者確定選擇觀看即可放送。

必要條件

  • Google Mobile Ads SDK 19.2.0 以上版本。

導入作業

整合插頁式獎勵廣告的主要步驟如下：

  • 載入廣告
  • 註冊全螢幕事件回呼
  • 處理獎勵回呼
  • 顯示廣告
  • [選用] 驗證 SSV 回呼

載入廣告

載入廣告時，請使用 RewardedInterstitialAd 類別的靜態 load() 方法。載入方法需要 Context、廣告單元 ID、AdRequest 物件，以及在廣告載入成功或失敗時收到通知的 RewardedInterstitialAdLoadCallback。載入的 RewardedInterstitialAd 物件會以參數形式提供給 onRewardedInterstitialAdLoaded() 回呼。

以下範例說明如何在 MainActivity 中載入 RewardedInterstitialAd。

Java

RewardedInterstitialAd.load(
    MainActivity.this,
    "AD_UNIT_ID",
    new AdRequest.Builder().build(),
    new RewardedInterstitialAdLoadCallback() {
      @Override
      public void onAdLoaded(RewardedInterstitialAd ad) {
        Log.d(TAG, "Ad was loaded.");
        rewardedInterstitialAd = ad;
      }

      @Override
      public void onAdFailedToLoad(LoadAdError loadAdError) {
        Log.d(TAG, "onAdFailedToLoad: " + loadAdError.getMessage());
        rewardedInterstitialAd = null;
      }
    });
MainActivity.java

Kotlin

RewardedInterstitialAd.load(
  this,
  "AD_UNIT_ID",
  AdRequest.Builder().build(),
  object : RewardedInterstitialAdLoadCallback() {
    override fun onAdLoaded(rewardedAd: RewardedInterstitialAd) {
      Log.d(TAG, "Ad was loaded.")
      rewardedInterstitialAd = rewardedAd
    }

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

將 AD_UNIT_ID 替換為廣告單元 ID。

註冊回呼

如要接收簡報事件的通知，您必須將 FullScreenContentCallback 物件傳遞至廣告的設定器。FullScreenContentCallback 物件會處理廣告成功或失敗顯示時，以及廣告遭到關閉時的回呼。下列程式碼顯示如何在 RewardedInterstitialAdLoadCallback 中設定匿名 FullScreenContentCallback 物件：

Java

rewardedInterstitialAd.setFullScreenContentCallback(
    new FullScreenContentCallback() {
      @Override
      public void onAdDismissedFullScreenContent() {
        // Called when fullscreen content is dismissed.
        Log.d(TAG, "The ad was dismissed.");
        // Make sure to set your reference to null so you don't
        // show it a second time.
        rewardedInterstitialAd = null;
        if (googleMobileAdsConsentManager.canRequestAds()) {
          loadRewardedInterstitialAd();
        }
      }

      @Override
      public void onAdFailedToShowFullScreenContent(AdError adError) {
        // Called when fullscreen content failed to show.
        Log.d(TAG, "The ad failed to show.");
        // Make sure to set your reference to null so you don't
        // show it a second time.
        rewardedInterstitialAd = null;
      }

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

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

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

Kotlin

rewardedInterstitialAd?.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.
      rewardedInterstitialAd = 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.
      rewardedInterstitialAd = 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

顯示獎勵插頁式廣告時，您可以使用 OnUserEarnedRewardListener 物件處理獎勵事件。

Java

rewardedInterstitialAd.show(
    MainActivity.this,
    new OnUserEarnedRewardListener() {
      @Override
      public void onUserEarnedReward(@NonNull RewardItem rewardItem) {
        Log.d(TAG, "The user earned the reward.");
        // Handle the reward.
        int rewardAmount = rewardItem.getAmount();
        String rewardType = rewardItem.getType();
      }
    });
MainActivity.java

Kotlin

rewardedInterstitialAd?.show(this) { 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

如果應用程式需要在伺服器端驗證回呼中取得額外資料，請使用獎勵廣告的自訂資料功能。在獎勵廣告物件上設定的任何字串值，都會傳遞至 SSV 回呼的 custom_data 查詢參數。如果未設定任何自訂資料值，SSV 回呼中就不會出現 custom_data 查詢參數值。

下列程式碼範例示範如何在要求廣告前，於有獎中介層廣告物件上設定自訂資料。

Java

RewardedInterstitialAd.load(
    context,
    AD_UNIT_ID,
    new AdRequest.Builder().build(),
    new RewardedInterstitialAdLoadCallback() {
      @Override
      public void onAdLoaded(RewardedInterstitialAd ad) {
        rewardedInterstitialAd = ad;
        ServerSideVerificationOptions options =
            new ServerSideVerificationOptions.Builder()
                .setCustomData("SAMPLE_CUSTOM_DATA_STRING")
                .build();
        rewardedInterstitialAd.setServerSideVerificationOptions(options);
      }
    });
RewardedInterstitialAdSnippets.java

Kotlin

RewardedInterstitialAd.load(
  context,
  AD_UNIT_ID,
  AdRequest.Builder().build(),
  object : RewardedInterstitialAdLoadCallback() {
    override fun onAdLoaded(ad: RewardedInterstitialAd) {
      rewardedInterstitialAd = ad
      val options =
        ServerSideVerificationOptions.Builder().setCustomData("SAMPLE_CUSTOM_DATA_STRING").build()
      rewardedInterstitialAd?.setServerSideVerificationOptions(options)
    }
  },
)
RewardedInterstitialAdSnippets.kt

將 SAMPLE_CUSTOM_DATA_STRING 換成自訂資料。

如要設定自訂獎勵字串，請務必在顯示廣告前完成設定。
