当请求 admob 横幅广告时，unity 应用程序崩溃，但对于插页式广告和视频广告效果很好

Question

我正在设置一个集成了 AdMob 插件的统一应用程序。一切正常，但当我请求横幅广告时，应用程序就会崩溃，但在请求插页式广告或视频广告时它工作正常

void Start()
{
 RequestBanner();
}
void RequestBanner()
{
     string banner_ID = "ca-app-pub-3940256099942544/6300978111";
 bannerAD = new BannerView(banner_ID,AdSize.SmartBanner, AdPosition.Top);
 AdRequest adRequest = new AdRequest.Builder().AddTestDevice("2077ef9a63d2b398840261c8221a0c9b").Build();
 bannerAD.LoadAd(adRequest);
}
public void Display_Banner()
{
 bannerAD.Show();
}
void RequestInterstitial()
{
if(interstitialAd !=null)
    {
        interstitialAd.Destroy();
    }
 string interstitial_ID = "ca-app-pub-3940256099942544/1033173712";
 interstitialAd = new InterstitialAd(interstitial_ID);
 AdRequest adRequest = new AdRequest.Builder().AddTestDevice("2077ef9a63d2b398840261c8221a0c9b").Build();
 interstitialAd.LoadAd(adRequest);
}
public void Display_InterstitalAD()
{
 if(interstitialAd.IsLoaded())
 {
     interstitialAd.Show();
 }
}

您应该在显示横幅之前检查广告是否已加载：

void RequestBanner()
{
    string banner_ID = "ca-app-pub-3940256099942544/6300978111";
    bannerAD = new BannerView(banner_ID,AdSize.SmartBanner, AdPosition.Top);
    bannerAD.OnAdLoaded += HandleOnAdLoaded;
    AdRequest adRequest = new AdRequest.Builder().AddTestDevice("2077ef9a63d2b398840261c8221a0c9b").Build();
    bannerAD.LoadAd(adRequest);
}

public void HandleOnAdLoaded(object sender, EventArgs args)
{
    bannerAD.Show();
}
