横幅广告不显示 Admob

Question

您好，感谢您的帮助，我正在尝试使用 android studio 中的 admob 在我的应用程序中实现一些广告，我遵循了所有教程，但是当我尝试加载我的应用程序时，没有广告如图所示，我正在尝试使用横幅示例广告 ("ca-app-pub-3940256099942544/6300978111")。

这是我的代码：

Adroid 清单

<meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-2069240735008902~XXXXXXX(Here is my admob id)">
</meta-data>

Build.gradle 应用程序

        MobileAds.initialize(this){}
        var mAdView:AdView = findViewById(R.id.anuncio1)
        val adRequest = AdRequest.Builder().build()
        mAdView.loadAd(adRequest)
        }
}

您的代码看起来完全符合预期。

我猜：您需要有互联网连接，即使是测试广告。否则，不显示任何内容。
