Admob 广告未加载 - 无法加载广告：0

我正在尝试加载 Admob Native 广告。以前（应用程序更新之前）曾经显示广告，但现在不显示。我已经在下面发布了代码、xml 和 Logcat。

Code

NativeExpressAdView adView = (NativeExpressAdView) myView.findViewById(R.id.adView);

    AdRequest request = new AdRequest.Builder()
            .addTestDevice("5BCFF0AAE83AF424648A954038C71DE6")
            .addTestDevice("A5E3E2068BD88202CBC281AD76984BEE")//infocus
            .build();

    adView.loadAd(request);

XML

<com.google.android.gms.ads.NativeExpressAdView
            android:id="@+id/adView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            ads:adSize="320x150"
            ads:adUnitId="ca-app-pub-5059726881726792/6223900262"></com.google.android.gms.ads.NativeExpressAdView>

您的代码没有错误。都很好。你只需要稍等一下。您的广告 ID 是新创建的，因此从 Google 服务器获取广告需要一些时间。您可以通过添加为早期应用程序创建的横幅/插页式广告 ID 来验证这一点，您将看到它们有效。所以给它一些时间，它很快就会起作用。至少对我来说，这种事经常发生。不能肯定地告诉你，但为什么不尝试一下呢？
