複数sceneからAdMobを呼び出す

AdMob.cs

using GoogleMobileAds.Api;
public class AdMob
{
    BannerView bannerView;
    public void Init()
    {
        MobileAds.Initialize(GetAppId());
    }
    string GetAppId() {
    {
        #if UNITY_ANDROID
            string appId = "ca-app-pub-3940256099942544~3347511713";
        #elif UNITY_IPHONE
            string appId = "ca-app-pub-3940256099942544~1458002511";
        #else
            string appId = "unexpected_platform";
        #endif
        return appId;
    }
    string GetAdUnitId() {
        #if UNITY_ANDROID
            string adUnitId = "ca-app-pub-3940256099942544/6300978111";

            string adUnitId = "ca-app-pub-3940256099942544/2934735716";
        #else
            string adUnitId = "unexpected_platform";
        #endif
        return adUnitId;
    }
    public void RequestBanner()
    {
        bannerView = new BannerView(GetAdUnitId(), AdSize.MediumRectangle, AdPosition.Center);
        AdRequest request = new AdRequest.Builder().Build();
        bannerView.LoadAd(request);
    }
    public void RequestBannerBottom()
    {
        bannerView = new BannerView(GetAdUnitId(), AdSize.MediumRectangle, AdPosition.Bottom);
        AdRequest request = new AdRequest.Builder().Build();
        bannerView.LoadAd(request);
    }
    public void Destroy()
    {
        bannerView.Destroy();
        bannerView = null;

{
    admob = new AdMob();
    admob.Init();
