我尝试在我的 Xamarin 项目中使用 AdMob。我的目标是在我的应用程序上显示奖励视频。我有无法解决的问题，想与您分享。这是我的环境:
- Xamarin v4.0.1.96
- Xamarin Android v6.0.1.10
- Xamarin.GooglePlayServices.Ads v27.0.0
我总是在真实设备上执行项目。万一问题来自调试环境，我已经在商店发布了应用程序，我遇到了与本地相同的问题。

public class ReloadCreditActivity : AppCompatActivityBase, IRewardedVideoAdListener
{
public IRewardedVideoAd RewardedVideoAd { get; set; }

RewardedVideoAd = MobileAds.GetRewardedVideoAdInstance(this);
RewardedVideoAd.RewardedVideoAdListener = this;
LoadRewardedVideoAd();
DisplayVideoButton.Click += (o, e) =>
{
ShowRewardedVideo();
};
}
public void LoadRewardedVideoAd()
{

_isRewardedVideoLoading = true;
Bundle extras = new Bundle();
extras.PutBoolean("_noRefresh", true);
var adMobAdapter = new AdMobAdapter();
AdRequest adRequest = new AdRequest.Builder()
//.AddTestDevice(AdRequest.DeviceIdEmulator)

.Build();
RewardedVideoAd.UserId = "pub-74XXXXXXXXXXXXXX";
RewardedVideoAd.LoadAd(AD_UNIT_ID, adRequest);
}
}
}
public void ShowRewardedVideo()
{
if (RewardedVideoAd.IsLoaded)
{
RewardedVideoAd.Show();
}
}
public void OnRewarded(IRewardItem reward)
{
Toast.MakeText(this, string.Format("OnRewarded ! currency: {0} amount: {1}", reward.GetType(), reward.Amount), ToastLength.Short).Show();
}
public void OnRewardedVideoAdClosed()
{
Toast.MakeText(this, "OnRewardedVideoAdClosed", ToastLength.Short).Show();
LoadRewardedVideoAd();
}
public void OnRewardedVideoAdFailedToLoad(int errorCode)
{
lock (_lock)
{
_isRewardedVideoLoading = false;
}
Toast.MakeText(this, "OnRewardedVideoAdFailedToLoad Code error : " + errorCode, ToastLength.Short).Show();
}
public void OnRewardedVideoAdLeftApplication()
{
Toast.MakeText(this, "OnRewardedVideoAdLeftApplication", ToastLength.Short).Show();
}
public void OnRewardedVideoAdLoaded()
{
lock (_lock)
{
_isRewardedVideoLoading = false;
}
Toast.MakeText(this, "OnRewardedVideoAdLoaded", ToastLength.Short).Show();
}
public void OnRewardedVideoAdOpened()
{
Toast.MakeText(this, "OnRewardedVideoAdOpened", ToastLength.Short).Show();
}
public void OnRewardedVideoStarted()
{
Toast.MakeText(this, "OnRewardedVideoStarted", ToastLength.Short).Show();
}
}
当我在此页面上导航时，应用程序始终引发 OnRewardedVideoAdFailedToLoad() 回调。我以前得到错误代码 0，但现在我得到错误代码 3。

我告诉自己，这可能是我与广告商的 admob 配置有问题，所以这是我的设置:
也许我在广告商的设置上做错了，所以这是我的广告商。

请给我您的反馈。 非常感谢。
最佳答案
我认为问题在于您的 Xamarin 项目中没有定义中介适配器。这些由各种广告代理商(如 vUngle)在其 SDK 中提供。不幸的是，它们目前都没有提供与 Xamarin 兼容的 SDK，因此您必须按照将外部程序集导入 Xamarin 的步骤进行操作。有几个人试图这样做(尝试搜索 Xamarin 论坛)，但我没有看到任何人发布有效的解决方案。
