Facebook Audience Network 的 Xamarin.Forms 实现

Question

我正在努力在我的 Xamarin.Forms 应用中实施 Facebook Audience Network。 可用的 nuget 包是旧的并且有过时的方法。

我能够自己实施广告，测试插页式广告是否正确显示，但当其他用户使用我的应用时，广告根本不显示。我在日志中看到 FAN 返回错误代码 1001 并显示“未填充”消息。

我做了什么：

• 添加到解决方案新的 Android 类解析项目。项目包含来自 Facebook 页面的“AudienceNetwork.aar”文件。构建操作集为 LibraryProjectZip
• 我不得不添加一些类来修复构建错误：

public partial class AdView
    {
        internal partial class IAdViewLoadConfigBuilderInvoker
        {
            IAdLoadAdConfig IAdLoadConfigBuilder.Build()
            {
                return Build();
            }

            IAdLoadConfigBuilder IAdLoadConfigBuilder.WithBid(string p0)
            {
                return WithBid(p0);
            }
        }
    }

    public partial class InterstitialAd
    {
        IAdLoadConfigBuilder IFullScreenAd.BuildLoadAdConfig()
        {
            return BuildLoadAdConfig();
        }

        IFullScreenAdShowConfigBuilder IFullScreenAd.BuildShowAdConfig()
        {
            return BuildShowAdConfig();
        }

        internal partial class IInterstitialAdLoadConfigBuilderInvoker
        {
            IAdLoadAdConfig IAdLoadConfigBuilder.Build()
            {
                return Build();
            }

            IAdLoadConfigBuilder IAdLoadConfigBuilder.WithBid(string p0)
            {
                return WithBid(p0);
            }
        }

        internal partial class IInterstitialAdShowConfigBuilderInvoker
        {
            IFullScreenAdShowAdConfig IFullScreenAdShowConfigBuilder.Build()
            {
                return Build();
            }
        }
    }

    public abstract partial class NativeAdBase
    {
        internal partial class INativeAdLoadConfigBuilderInvoker
        {

            IAdLoadAdConfig IAdLoadConfigBuilder.Build()
            {
                return Build();
            }

            IAdLoadConfigBuilder IAdLoadConfigBuilder.WithBid(string p0)
            {
                return WithBid(p0);
            }
        }
    }

    public partial class RewardedVideoAd
    {
        IAdLoadConfigBuilder IFullScreenAd.BuildLoadAdConfig()
        {
            return BuildLoadAdConfig();
        }

        IFullScreenAdShowConfigBuilder IFullScreenAd.BuildShowAdConfig()
        {
            return BuildShowAdConfig();
        }

        internal partial class IRewardedVideoAdLoadConfigBuilderInvoker
        {
            IAdLoadAdConfig IAdLoadConfigBuilder.Build()
            {
                return Build();
            }

            IAdLoadConfigBuilder IAdLoadConfigBuilder.WithBid(string p0)
            {
                return WithBid(p0);
            }
        }

        internal partial class IRewardedVideoAdShowConfigBuilderInvoker
        {
            IFullScreenAdShowAdConfig IFullScreenAdShowConfigBuilder.Build()
            {
                return Build();
            }
        }
    }

public abstract partial class AdComponentFrameLayout
    {
        public void SetLayoutParams(ViewGroup.LayoutParams p0)
        {
            SetLayoutParams(p0);
        }
    }

    public abstract partial class AdNativeComponentView
    {
        public void SetLayoutParams(ViewGroup.LayoutParams p0)
        {
            SetLayoutParams(p0);
        }
    }

    internal partial class IInterstitialAdApiInvoker
    {
        IAdLoadConfigBuilder IFullScreenAd.BuildLoadAdConfig()
        {
            return BuildLoadAdConfig();
        }

        IFullScreenAdShowConfigBuilder IFullScreenAd.BuildShowAdConfig()
        {
            return BuildShowAdConfig();
        }
    }

    public partial class InitSettingsBuilder
    {
        AudienceNetworkAds.IInitSettingsBuilder AudienceNetworkAds.IInitSettingsBuilder.WithInitListener(AudienceNetworkAds.IInitListener p0)
        {
            return WithInitListener(p0);
        }

        AudienceNetworkAds.IInitSettingsBuilder AudienceNetworkAds.IInitSettingsBuilder.WithMediationService(string p0)
        {
            return WithMediationService(p0);
        }

        AudienceNetworkAds.IInitSettingsBuilder AudienceNetworkAds.IInitSettingsBuilder.WithPlacementIds(IList<string> p0)
        {
            return WithPlacementIds(p0);
        }
    }

    internal partial class IRewardedVideoAdApiInvoker
    {
        IAdLoadConfigBuilder IFullScreenAd.BuildLoadAdConfig()
        {
            return BuildLoadAdConfig();
        }

        IFullScreenAdShowConfigBuilder IFullScreenAd.BuildShowAdConfig()
        {
            return BuildShowAdConfig();
        }
    }

• 在 Android 项目的 MainActivity 中： AudienceNetworkAds.Initialize(this);
• 插页式广告渲染器

public class InterstitalAdsRenderer : IInterstitalAdsService
    {
        InterstitialAd _interstitial;

        public void Show(string adsId)
        {
            //AdSettings.AddTestDevice("fe9823bf-946e-4a43-b38c-f958d0bfaa31");
            _interstitial = new InterstitialAd(Application.Context, adsId);
            var loadAdConfig = _interstitial.BuildLoadAdConfig()
                .WithAdListener(new InterstitialAdListener(_interstitial))
                .Build();
            _interstitial.LoadAd(loadAdConfig);
        }
    }

    internal class InterstitialAdListener : Java.Lang.Object, IInterstitialAdListener
    {
        private readonly InterstitialAd _interstitial;

        public InterstitialAdListener(InterstitialAd interstitial)
        {
        }

        public void OnAdClicked(IAd p0)
        {
        }

        public void OnAdLoaded(IAd p0)
        {
            _interstitial.Show();
        }

        public void OnError(IAd p0, AdError p1)
        {
            Console.WriteLine("OnError: " + p1.ErrorMessage);
        }

        public void OnLoggingImpression(IAd p0)
        {
        }

        public void OnInterstitialDismissed(IAd p0)
        {
        }

        public void OnInterstitialDisplayed(IAd p0)
        {
        }
    }

正如我之前所说，测试设备中的测试广告（添加到测试设备的模拟器）可以正确显示广告，但在生产环境中没有广告：/

有人在 Xamarin.Forms 项目中实施了 Facebook 广告，可以告诉我如何正确执行此操作吗？

此错误通常表示您尚未登录 Facebook 应用程序或 Facebook 应用程序在您运行应用程序的设备中不可用
