Admob 广告未在 Unity、C# 中显示

Question

我的 Admob 广告没有在我的 Android 应用中显示，我尝试了所有方法，不同版本的 unity、广告类型、重新安装 admob 插件、用于 android 编译的播放器设置的不同组合。

登录Unity（我在Android上测试过）是：

虚拟已加载
虚拟ShowIntertitial

代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
using GoogleMobileAds.Api;

使用以下格式初始化广告：

MobileAds.Initialize(appID);

您还尝试在启动功能中一起加载和显示广告，这可能是您遇到问题的原因之一。 在启动函数中加载广告，但通过调用以下函数在任何按钮点击时显示广告

  void ShowAd(){
    if (this.InterFULLSC.IsLoaded()) {
                this.InterFULLSC.Show();
            }
        }
