如果admob广告未统一加载，如何加载自定义横幅广告

Question

如果admob横幅广告未加载，我尝试加载自定义横幅广告（其他游戏横幅广告），并在加载横幅广告时销毁自定义广告。 我写了一个代码，但是不起作用..这是代码。

public class AdScript : MonoBehaviour {

    private BannerView bannerView;

    void Start () 
    {    
        this.showBannerAd();
    }

    private void showBannerAd()
    {
        string adID = "ca-app-pub-9238312914970318/8415382856";
        bannerView = new BannerView(adID, AdSize.SmartBanner, AdPosition.Bottom);

        bannerView.OnAdFailedToLoad += HandleOnAdFailedToLoad;
        bannerView.OnAdLoaded += HandleOnAdLoaded;
        AdRequest request = new AdRequest.Builder().Build();

        bannerView.LoadAd(request);
    }

    public void HandleOnAdLoaded(object sender, EventArgs args)
    {
        print("HandleAdLoaded event received");
    }

    public void HandleOnAdFailedToLoad(object sender, AdFailedToLoadEventArgs args)
    {
        print("HandleFailedToReceiveAd event received with message: "
        + args.Message);
        // writing custom ad code here.. if admob banner ad not loaded
    }

}

尝试销毁横幅，然后初始化自定义广告横幅，设置计时器以尝试再次启动admob广告
