Anuncios intersticiales recompensados

插页式激励广告是一种激励用户的广告格式,采用这种格式时,您可以通过在应用中的自然过渡点自动展示的广告向用户提供奖励。与激励广告不同,用户无需自行选择即可观看插页式激励广告。

前提条件

Siempre prueba con anuncios de prueba

El siguiente código de muestra contiene un ID de unidad de anuncios que puedes usar para solicitar anuncios de prueba. Se configuró especialmente para mostrar anuncios de prueba en lugar de anuncios de producción para cada solicitud, por lo que es seguro usarlo.

Sin embargo, después de registrar una app en la interfaz web deAdMob y crear tus propios ID de unidades de anuncios para usar en ella, configura tu dispositivo como un dispositivo de prueba de forma explícita durante el desarrollo.

iOS

Inicializa el SDK de anuncios para dispositivos móviles

Antes de cargar anuncios, haz que tu app inicialice el SDK de anuncios para dispositivos móviles llamando a MobileAds.Initialize(). Esto debe hacerse solo una vez, idealmente cuando se inicia la app.

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.
        });
    }
}

Si usas mediación, espera hasta que se produzca la devolución de llamada antes de cargar anuncios, ya que esto garantizará que todos los adaptadores de mediación se inicialicen.

实现

植入插页式激励广告的主要步骤如下所示:

  1. 加载插页式激励广告
  2. [可选] 验证服务器端验证 (SSV) 回调
  3. 通过奖励回调展示插页式激励广告
  4. 监听插页式激励广告事件
  5. 清理插页式激励广告
  6. 预加载下一个插页式激励广告

加载插页式激励广告

插页式激励广告的加载是通过对 RewardedInterstitialAd 类使用静态 Load() 方法完成的。该加载方法需要使用广告单元 ID、AdRequest 对象以及在广告加载成功或失败时调用的完成处理程序。已加载的 RewardedInterstitialAd 对象会以完成处理程序中的参数的形式提供。以下示例展示了如何加载 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;
          });
  }

[可选] 验证服务器端验证 (SSV) 回调

对于需要服务器端验证回调中额外数据的应用,应使用插页式激励广告的自定义数据功能。在激励广告对象上设置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 查询参数值将不会包含在 SSV 回调中。

以下代码示例演示了如何在加载插页式激励广告后设置 SSV 选项。

// 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。

通过奖励回调展示插页式激励广告

展示广告时,您必须提供一个回调,用于处理用户奖励。每次加载时,广告仅可展示一次。您可以使用 CanShowAd() 方法验证广告是否已做好展示准备。

以下代码演示了展示插页式激励广告的最佳方法。

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));
        });
    }
}

监听插页式激励广告事件

若要进一步自定义您广告的行为,您可以在广告生命周期内加入许多事件。您可以通过注册代理来监听这些事件,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);
    };
}

清理插页式激励广告

创建完 RewardedInterstitialAd 后,请确保在放弃对它的引用前调用 Destroy() 方法:

_rewardedInterstitialAd.Destroy();

这会通知插件已不再使用该对象,且可回收它占用的内存。此方法调用失败将导致内存泄漏。

预加载下一个插页式激励广告

RewardedInterstitialAd 是一次性对象。这意味着,在插页式激励广告展示后,该对象就无法再使用了。若要再请求一个插页式激励广告,您需要加载一个新的 RewardedInterstitialAd 对象。

若要为下一次展示机会准备好插页式激励广告,请在 OnAdFullScreenContentClosedOnAdFullScreenContentFailed 广告事件引发后预加载插页式激励广告。

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();
    };
}
