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，可讓使用者透過放送的廣告提供獎勵自動在應用程式的自然轉換期間自動切換。有別於獎勵廣告必須啟用才能觀看插頁式獎勵廣告。

先備知識

完成入門指南。

一律使用測試廣告進行測試

以下程式碼範例包含廣告單元 ID，供您請求測試廣告該功能已設定為傳回測試廣告，而不是導入及導入廣告，以備不時之需。

不過，在 Ad Manager 網頁介面，並建立自己的廣告單元用於應用程式的 ID，請明確將裝置設為測試裝置裝置。

/6499/example/rewarded-interstitial

初始化 Mobile Ads SDK

載入廣告前，請呼叫應用程式，以便呼叫 MobileAds.Initialize()。這項操作只需進行一次，最好在應用程式啟動時。

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，再於以確保所有中介服務轉接程式的初始化完成。

導入作業

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
清除插頁式獎勵廣告
預先載入下一個插頁式獎勵廣告

載入插頁式獎勵廣告

系統會使用靜態 Load() 完成載入插頁式獎勵廣告方法。RewardedInterstitialAd載入方法需要有廣告單位 ID、AdManagerAdRequest 物件和完成度廣告載入成功或失敗時呼叫的處理常式。載入系統會在完成提示中提供 RewardedInterstitialAd 物件做為參數處理常式。以下範例說明如何載入 RewardedInterstitialAd。


  // This ad unit is configured to always serve test ads.
  private string _adUnitId = "/6499/example/rewarded-interstitial";

  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 AdManagerAdRequest();
      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

需要在伺服器端驗證作業中使用額外資料的應用程式回呼應使用插頁式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 custom_data SSV 回呼的查詢參數。如果未設定自訂資料值， custom_data 查詢參數值不會納入 SSV 回呼。

以下程式碼範例示範如何在已載入插頁式獎勵廣告。

// 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，就必須在顯示廣告。

顯示含有獎勵回呼的插頁式獎勵廣告

顯示廣告時，您必須提供回呼來處理使用者。廣告每次載入時只能顯示一次。使用 CanShowAd() 方法確認廣告已經準備好可以放送。

以下程式碼說明顯示獎勵廣告的最佳方法插頁式廣告。

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，您可以連結至事件發生。註冊委派項目，即可監聽這些事件如下所示。

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);
    };
}

清除插頁式獎勵廣告

完成 RewardedInterstitialAd 後，請務必呼叫 Destroy() 方法，再捨棄參照：

_rewardedInterstitialAd.Destroy();

這會通知外掛程式，說明該物件已不再使用，以及該物件的記憶體可收回這些物件。無法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 是一次性的物件。這意味著如果獎勵廣告插頁式廣告顯示後，就無法再使用該物件。如需索取另一個地址，請按照下列步驟操作：插頁式獎勵廣告，您需要載入新的 RewardedInterstitialAd 物件。

如要為下一個曝光商機設定插頁式獎勵廣告，在 OnAdFullScreenContentClosed 或會引發 OnAdFullScreenContentFailed 個廣告事件。

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();
    };
}
