我无法将 admob 横幅和插页式广告添加到我的 webview(Html css JavaScript) android 测试项目

Question

打开应用程序时不加载广告。除了我自己编写的代码块之外，我没有在 HTML 或 Javascript 文件中添加任何内容，这是我可以通过在互联网上搜索来完成的。 英文拼写可能有误，我用谷歌翻译写的

看来您忘记初始化ad sdk。检查以下步骤：

1。确保您在manifest.xml中添加了广告应用程序ID

<manifest>
<application>
  <!-- Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713 -->
  <meta-data
      android:name="com.google.android.gms.ads.APPLICATION_ID"
      android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/>

           ...

  </application>
</manifest>

2。在 MainActivity 的 onCreate 中初始化移动 sdk，并在 MobileAds 初始化后加载广告。

MobileAds.initialize(this, new OnInitializationCompleteListener() {
   @Override
   public void onInitializationComplete(InitializationStatus initializationStatus) {
    //Now you can load ad
    AdRequest adRequest = new AdRequest.Builder().build();
    adView.loadAd(adRequest);
        }
});
