AndroidAdmobInterstitialAd已弃用

经过快速搜索，我发现我们需要使用

public abstract class InterstitialAd extends Object

代替

public final class InterstitialAd extends Object

所以你需要使用：

com.google.android.gms.ads.interstitial.InterstitialAd

代替：

come.google.android.gms.ads

这就是我们与新包交互的方式：

public class AdManager 
{
    private var interstitialAd: InterstitialAd? = null
    private var mRewardedVideoAd: RewardedAd? = null
    private var currentNativeAd: NativeAd? = null
    private var builder: AdLoader.Builder? = null

20.0.0 版中有许多重大更改。19.7.0 版引入了许多新的 API，并弃用或重命名了许多类，为 20.0.0 版做准备。
