請求admob橫幅廣告時，Unity應用程序崩潰，但對插頁式廣告和視頻廣告而言效果很好

Question

我正在設置一個集成了AdMob插件的統一應用。 一切正常，但是當我請求橫幅廣告時，應用程序崩潰了，但是當請求插頁式廣告或視頻廣告時，它運行正常

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();
 }
}

在顯示橫幅廣告之前，您應該檢查廣告是否已加載：

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();
}
