横幅广告不显示广告

Question

你好，谢谢你帮助我，我试着在安卓工作室用admob在我的应用程序中实现一些广告，我遵循了所有的教程，但是当我尝试加载我的应用程序时，没有显示广告，我尝试使用横幅示例广告("ca- app -pub-3940256099942544/6300978111")。

这是我的代码：

Adroid Manifest

<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

ependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.1.0'

    override fun onCreate(savedInstanceState: Bundle?) {

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

谢谢大家的帮助，我会很高兴的。

您的代码看起来就像它应该有的样子。

我猜:你需要有一个互联网连接，即使是为了考试广告。否则，什么都不会显示。
