我尝试在我的Xamarin项目中使用AdMob。我的目标是在我的应用中显示奖励视频。我遇到了无法解决的问题，并希望与您分享。下面是我的环境：Xamarin Admob RewardedVideoAd代码错误0＆3
- Xamarin v4.0.1.96
- Xamarin的Android v6.0.1.10
- Xamarin.GooglePlayServices.Ads v27.0.0
我总是在执行项目一个真实的设备。如果问题来自调试环境，我已经在商店上发布了应用程序，并且遇到了与本地相同的问题。
using System;
using Android.OS;
using Android.Views;
using Android.Gms.Ads;
public class ReloadCreditActivity : AppCompatActivityBase, IRewardedVideoAdListener
{
public IRewardedVideoAd RewardedVideoAd { get; set; }
public Button DisplayVideoButton { get; set; }
private static string AD_UNIT_ID = "ca-app-pub-XXXXXXXXXXXXXX25/XXXXXXXX99";
private bool _isRewardedVideoLoading;
private static object _lock = new object();
protected IRewardedVideoAd _rewardedVideoAd;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.ReloadCreditLayout);
DisplayVideoButton = FindViewById<Button>(Resource.Id.tabCreditFreemieum_DisplayVideo);
RewardedVideoAd = MobileAds.GetRewardedVideoAdInstance(this);
RewardedVideoAd.RewardedVideoAdListener = this;
LoadRewardedVideoAd();
DisplayVideoButton.Click += (o, e) =>
{
ShowRewardedVideo();
};
}
public void LoadRewardedVideoAd()
{
lock (_lock)
{
if (!_isRewardedVideoLoading && !RewardedVideoAd.IsLoaded)
{
_isRewardedVideoLoading = true;
Bundle extras = new Bundle();
extras.PutBoolean("_noRefresh", true);
var adMobAdapter = new AdMobAdapter();
AdRequest adRequest = new AdRequest.Builder()
//.AddTestDevice(AdRequest.DeviceIdEmulator)
//.AddTestDevice("FE5692B3DAD1B4CE3BE3BDA2FF4B6103")
//.AddNetworkExtrasBundle(adMobAdapter.Class, extras)
.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();
}
}
当我浏览此页面时，应用程序始终会引发OnRewardedVideoAdFailedToLoad（）回调。我用来获取错误代码0，但目前我得到了错误代码3

我告诉自己，也许这是我的AdMob配置有问题广告客户，所以这里是我的设置：
也许我做错了广告客户的设置，所以这里是我的广告客户。
