Java 错误：（125，25）错误：AdRequest（）在AdRequest中具有私有访问权限

我正在android游戏中编辑，它没有主XML，我想在屏幕上放一个插入式广告。。开发人员说将单元ad id放入String.Xml中。。但没有显示任何广告 我把Firebase的东西放在了广告上，但我遇到了这个错误

Error:(125, 25) error: AdRequest() has private access in AdRequest

这是我的String.xml：

<?xml version="1.0" encoding="utf-8"?>

因此，请任何人在每场比赛结束后帮我在游戏中插入一则广告

试试这个：

private InterstitialAd interstitial;


//Create the interstitial Ad.
    interstitial = new InterstitialAd(this);

    //Set unit id.
    interstitial.setAdUnitId("ca-app-pub-3940256099942544/1033173712");  //test interstitial AD

    //Create request.
    AdRequest adRequest = new AdRequest.Builder().build();

    //Start loading...
    interstitial.loadAd(adRequest);

在游戏结束的地方添加以下内容：

  //Interstitial AD
        if(interstitial.isLoaded()) {
            interstitial.show();
        }
        else {
            AdRequest interstitialRequest = new AdRequest.Builder().build();
            interstitial.loadAd(interstitialRequest);
        }

---

希望有帮助

尝试以下方法可能会对您有所帮助：对于间隙广告：-

  //Interstitial AD
        if(interstitial.isLoaded()) {
            interstitial.show();
        }
        else {
            AdRequest interstitialRequest = new AdRequest.Builder().build();
            interstitial.loadAd(interstitialRequest);
        }
