java - 广告未加载

Question

我按照有关插页式广告的谷歌教程进行操作，但每当我尝试显示广告时，它都不会加载。我尝试使用 AdListener 而不是 interstitial.isLoaded，但结果仍然相同。我还给广告加载了几次超过 2 分钟的时间，所以肯定出了什么问题。

我正在使用 AVD，这可能是问题所在吗？不过，当我使用浏览器时，它可以很好地连接到互联网。

如果您遇到此错误:

could not find com.google.android.gms.ads.AdActivity, please make sure it is declared in AndroidManifest.xml

然后在 <application> 中添加此 Activity 声明你的 list 中的标签应该修复它:

<activity android:name="com.google.android.gms.ads.AdActivity"
         android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
