插頁式獎勵廣告 (Beta 版)

插頁式獎勵廣告是一種獎勵廣告格式，可讓您在應用程式自然轉換時自動顯示廣告，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

完成入門指南。

請務必使用測試廣告進行測試

下列範例程式碼包含廣告單元 ID，可用於要求測試廣告。系統已特別將其設定為針對每項請求傳回測試廣告，而非正式廣告，因此可安全使用。

不過，在 AdMob 網頁介面中註冊應用程式，並建立要用於應用程式的廣告單元 ID 後，請在開發期間明確將裝置設為測試裝置。

Android

ca-app-pub-3940256099942544/5354046379

iOS

ca-app-pub-3940256099942544/6978759866

初始化 Mobile Ads SDK

在載入廣告之前，請讓應用程式呼叫 MobileAds.Initialize()，初始化 Mobile Ads SDK。這項操作只需執行一次，最好是在應用程式啟動時執行。

using GoogleMobileAds;
using GoogleMobileAds.Api;

public class GoogleMobileAdsDemoScript : MonoBehaviour
{
    public void Start()
    {
        // Initialize the Google Mobile Ads SDK.
        MobileAds.Initialize((InitializationStatus initStatus) =>
        {
            // This callback is called once the MobileAds SDK is initialized.
        });
    }
}

如果您使用中介服務，請等到回呼發生後再載入廣告，這樣可確保所有中介服務轉換介面都已初始化。

實作

整合插頁式獎勵廣告的主要步驟如下：

載入插頁式獎勵廣告
[選用] 驗證伺服器端驗證 (SSV) 回呼
顯示含有獎勵回呼的插頁式獎勵廣告
監聽插頁式獎勵廣告事件
清理插頁式獎勵廣告
預先載入下一個插頁式獎勵廣告

載入插頁式獎勵廣告

您可以使用 RewardedInterstitialAd 類別的靜態 Load() 方法，載入插頁式獎勵廣告。載入方法需要廣告單元 ID、AdRequest 物件，以及在廣告載入成功或失敗時呼叫的完成處理常式。載入的 RewardedInterstitialAd 物件會做為參數提供至完成處理常式。以下範例說明如何載入 RewardedInterstitialAd。


  // These ad units are configured to always serve test ads.
#if UNITY_ANDROID
  private string _adUnitId = "ca-app-pub-3940256099942544/5354046379";
#elif UNITY_IPHONE
  private string _adUnitId = "ca-app-pub-3940256099942544/6978759866";
#else
  private string _adUnitId = "unused";
#endif

  private RewardedInterstitialAd _rewardedInterstitialAd;

  /// <summary>
  /// Loads the rewarded interstitial ad.
  /// </summary>
  public void LoadRewardedInterstitialAd()
  {
      // Clean up the old ad before loading a new one.
      if (_rewardedInterstitialAd != null)
      {
            _rewardedInterstitialAd.Destroy();
            _rewardedInterstitialAd = null;
      }

      Debug.Log("Loading the rewarded interstitial ad.");

      // create our request used to load the ad.
      var adRequest = new AdRequest();
      adRequest.Keywords.Add("unity-admob-sample");

      // send the request to load the ad.
      RewardedInterstitialAd.Load(_adUnitId, adRequest,
          (RewardedInterstitialAd ad, LoadAdError error) =>
          {
              // if error is not null, the load request failed.
              if (error != null || ad == null)
              {
                  Debug.LogError("rewarded interstitial ad failed to load an ad " +
                                 "with error : " + error);
                  return;
              }

              Debug.Log("Rewarded interstitial ad loaded with response : "
                        + ad.GetResponseInfo());

              _rewardedInterstitialAd = ad;
          });
  }

[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使用額外資料，則應使用獎勵插頁式廣告的自訂資料功能。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。如果未設定自訂資料值，SSV 回呼中就不會包含 custom_data 查詢參數值。

以下程式碼範例示範如何在載入獎勵式插頁廣告後設定 SSV 選項。

// send the request to load the ad.
RewardedInterstitialAd.Load(_adUnitId,
                            adRequest,
                            (RewardedInterstitialAd ad, LoadAdError error) =>
    {
        // If the operation failed, an error is returned.
        if (error != null || ad == null)
        {
            Debug.LogError("Rewarded interstitial ad failed to load an ad " +
                           " with error : " + error);
            return;
        }

        // If the operation completed successfully, no error is returned.
        Debug.Log("Rewarded interstitial ad loaded with response : " +
                   ad.GetResponseInfo());
        
        // Create and pass the SSV options to the rewarded ad.
        var options = new ServerSideVerificationOptions
                              .Builder()
                              .SetCustomData("SAMPLE_CUSTOM_DATA_STRING")
                              .Build()
        ad.SetServerSideVerificationOptions(options);
        
});

如要設定自訂獎勵字串，請務必在顯示廣告前設定。

顯示含有獎勵回呼的插頁式獎勵廣告

呈現廣告時，您必須提供回呼，以便為使用者處理獎勵。每次載入只能顯示一次廣告。使用 CanShowAd() 方法驗證廣告是否已準備好顯示。

以下程式碼提供顯示獎勵插頁式廣告的最佳方法。

public void ShowRewardedInterstitialAd()
{
    const string rewardMsg =
        "Rewarded interstitial ad rewarded the user. Type: {0}, amount: {1}.";

    if (rewardedInterstitialAd != null && rewardedInterstitialAd.CanShowAd())
    {
        rewardedInterstitialAd.Show((Reward reward) =>
        {
            // TODO: Reward the user.
            Debug.Log(String.Format(rewardMsg, reward.Type, reward.Amount));
        });
    }
}

監聽插頁式獎勵廣告事件

如要進一步自訂廣告行為，您可以鉤住廣告生命週期中的多個事件。如要監聽這些事件，請註冊委派函，如下所示。

private void RegisterEventHandlers(RewardedInterstitialAd ad)
{
    // Raised when the ad is estimated to have earned money.
    ad.OnAdPaid += (AdValue adValue) =>
    {
        Debug.Log(String.Format("Rewarded interstitial ad paid {0} {1}.",
            adValue.Value,
            adValue.CurrencyCode));
    };
    // Raised when an impression is recorded for an ad.
    ad.OnAdImpressionRecorded += () =>
    {
        Debug.Log("Rewarded interstitial ad recorded an impression.");
    };
    // Raised when a click is recorded for an ad.
    ad.OnAdClicked += () =>
    {
        Debug.Log("Rewarded interstitial ad was clicked.");
    };
    // Raised when an ad opened full screen content.
    ad.OnAdFullScreenContentOpened += () =>
    {
        Debug.Log("Rewarded interstitial ad full screen content opened.");
    };
    // Raised when the ad closed full screen content.
    ad.OnAdFullScreenContentClosed += () =>
    {
        Debug.Log("Rewarded interstitial ad full screen content closed.");
    };
    // Raised when the ad failed to open full screen content.
    ad.OnAdFullScreenContentFailed += (AdError error) =>
    {
        Debug.LogError("Rewarded interstitial ad failed to open " +
                       "full screen content with error : " + error);
    };
}

清理插頁式獎勵廣告

使用 RewardedInterstitialAd 完成後，請務必先呼叫 Destroy() 方法，再放棄對該物件的參照：

_rewardedInterstitialAd.Destroy();

這會通知外掛程式，該物件已不再使用，因此可以回收該物件所占用的記憶體。未呼叫此方法會導致記憶體流失。

預先載入下一個插頁式獎勵廣告

RewardedInterstitialAd 是一次性物件。也就是說，一旦獎勵式插頁式廣告顯示後，就無法再次使用該物件。如要要求另一則獎勵式插頁式廣告，您必須載入新的 RewardedInterstitialAd 物件。

如要為下次曝光機會準備獎勵插頁式廣告，請在 OnAdFullScreenContentClosed 或 OnAdFullScreenContentFailed 廣告事件觸發時預先載入獎勵插頁式廣告。

private void RegisterReloadHandler(RewardedInterstitialAd ad)
{
    // Raised when the ad closed full screen content.
    ad.OnAdFullScreenContentClosed += ()
    {
        Debug.Log("Rewarded interstitial ad full screen content closed.");

        // Reload the ad so that we can show another as soon as possible.
        LoadRewardedInterstitialAd();
    };
    // Raised when the ad failed to open full screen content.
    ad.OnAdFullScreenContentFailed += (AdError error) =>
    {
        Debug.LogError("Rewarded interstitial ad failed to open " +
                       "full screen content with error : " + error);

        // Reload the ad so that we can show another as soon as possible.
        LoadRewardedInterstitialAd();
    };
}
