所谓激励广告,指的是用户可以选择与之互动来换取的一种广告 获取应用内奖励。本指南介绍了如何植入 AdMob 转换为 Unity 应用。
阅读一些客户成功案例: 案例研究 1, 案例研究 2。本指南介绍了如何在 Unity 应用中植入激励广告。
前提条件
- 完成入门指南。
始终使用测试广告进行测试
以下示例代码包含一个广告单元 ID,可用于请求 测试广告。该测试广告单元已经过专门配置 会返回测试广告 制作出来的广告,确保安全使用。
不过,当您在 AdMob 网页界面并创建您自己的广告单元 要在您的应用中使用的 ID,请明确将设备配置为测试 设备 开发。

初始化移动广告 SDK
加载广告之前,请先调用
MobileAds.Initialize()
。此操作仅需执行一次,最好是在应用启动时执行。
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.
});
}
}
如果您使用的是中介功能,请等到回调发生后再按 这样可确保初始化所有中介适配器
实现
植入激励广告的主要步骤如下所示:
- 加载激励广告
- [可选] 验证服务器端验证 (SSV) 回调
- 通过奖励回调展示激励广告
- 监听激励广告事件
- 清理激励广告
- 预加载下一个激励广告
加载激励广告
激励广告的加载是通过在Load()
RewardedAd
类。已加载的 RewardedAd
对象是作为
参数。以下示例展示了如何加载
RewardedAd
。
// These ad units are configured to always serve test ads.
#if UNITY_ANDROID
private string _adUnitId = "ca-app-pub-3940256099942544/5224354917";
#elif UNITY_IPHONE
private string _adUnitId = "ca-app-pub-3940256099942544/1712485313";
#else
private string _adUnitId = "unused";
#endif
private RewardedAd _rewardedAd;
/// <summary>
/// Loads the rewarded ad.
/// </summary>
public void LoadRewardedAd()
{
// Clean up the old ad before loading a new one.
if (_rewardedAd != null)
{
_rewardedAd.Destroy();
_rewardedAd = null;
}
Debug.Log("Loading the rewarded ad.");
// create our request used to load the ad.
var adRequest = new AdRequest();
// send the request to load the ad.
RewardedAd.Load(_adUnitId, adRequest,
(RewardedAd ad, LoadAdError error) =>
{
// if error is not null, the load request failed.
if (error != null || ad == null)
{
Debug.LogError("Rewarded ad failed to load an ad " +
"with error : " + error);
return;
}
Debug.Log("Rewarded ad loaded with response : "
+ ad.GetResponseInfo());
_rewardedAd = ad;
});
}
[可选] 验证服务器端验证 (SSV) 回调
在服务器端验证中需要额外数据的应用
回调应使用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会传递给 custom_data
查询参数。如果未设置自定义数据值,
custom_data
查询参数值不会出现在 SSV 回调中。
以下代码示例演示了如何在 激励广告。
// send the request to load the ad.
RewardedAd.Load(_adUnitId, adRequest, (RewardedAd ad, LoadAdError error) =>
{
// If the operation failed, an error is returned.
if (error != null || ad == null)
{
Debug.LogError("Rewarded ad failed to load an ad with error : " + error);
return;
}
// If the operation completed successfully, no error is returned.
Debug.Log("Rewarded 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,则必须在显示 。
通过奖励回调展示激励广告
展示广告时,您必须提供一个回调来处理奖励
用户。每次加载时,广告仅可展示一次。使用 CanShowAd()
方法
确认广告已做好展示准备。
以下代码演示了展示激励广告的最佳方法。
public void ShowRewardedAd()
{
const string rewardMsg =
"Rewarded ad rewarded the user. Type: {0}, amount: {1}.";
if (rewardedAd != null && rewardedAd.CanShowAd())
{
rewardedAd.Show((Reward reward) =>
{
// TODO: Reward the user.
Debug.Log(String.Format(rewardMsg, reward.Type, reward.Amount));
});
}
}
监听激励广告事件
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,如打开、关闭等等。监听 注册 delegate 以控制这些事件,如下所示。
private void RegisterEventHandlers(RewardedAd ad)
{
// Raised when the ad is estimated to have earned money.
ad.OnAdPaid += (AdValue adValue) =>
{
Debug.Log(String.Format("Rewarded ad paid {0} {1}.",
adValue.Value,
adValue.CurrencyCode));
};
// Raised when an impression is recorded for an ad.
ad.OnAdImpressionRecorded += () =>
{
Debug.Log("Rewarded ad recorded an impression.");
};
// Raised when a click is recorded for an ad.
ad.OnAdClicked += () =>
{
Debug.Log("Rewarded ad was clicked.");
};
// Raised when an ad opened full screen content.
ad.OnAdFullScreenContentOpened += () =>
{
Debug.Log("Rewarded ad full screen content opened.");
};
// Raised when the ad closed full screen content.
ad.OnAdFullScreenContentClosed += () =>
{
Debug.Log("Rewarded ad full screen content closed.");
};
// Raised when the ad failed to open full screen content.
ad.OnAdFullScreenContentFailed += (AdError error) =>
{
Debug.LogError("Rewarded ad failed to open full screen content " +
"with error : " + error);
};
}
清理激励广告
创建完 RewardedAd
后,请确保在放弃对它的引用前调用 Destroy()
方法:
_rewardedAd.Destroy();
这会通知插件该对象已不再使用,以及 可收回。此方法调用失败会导致内存泄漏。
预加载下一个激励广告
RewardedAd
是一次性对象。也就是说,在展示激励广告后
无法再次使用该对象。若要再请求一个激励广告
您需要创建一个新的 RewardedAd
对象。
若要为下一次展示机会准备好激励广告,请在 OnAdFullScreenContentClosed
或 OnAdFullScreenContentFailed
广告事件引发后预加载激励广告。
private void RegisterReloadHandler(RewardedAd ad)
{
// Raised when the ad closed full screen content.
ad.OnAdFullScreenContentClosed += () =>
{
Debug.Log("Rewarded Ad full screen content closed.");
// Reload the ad so that we can show another as soon as possible.
LoadRewardedAd();
};
// Raised when the ad failed to open full screen content.
ad.OnAdFullScreenContentFailed += (AdError error) =>
{
Debug.LogError("Rewarded ad failed to open full screen content " +
"with error : " + error);
// Reload the ad so that we can show another as soon as possible.
LoadRewardedAd();
};
}
