广告未加载

Question

我遵循关于插页式广告的Google教程，但每当我尝试显示我的广告时，它都不会被加载。我试过使用AdListener而不是interstitial.isLoaded，但结果仍然相同。我也给了广告超过2分钟来加载几次，所以有些事情一定是错的。

我正在使用AVD，这可能是问题吗？当我使用浏览器时，它可以连接到互联网。

如果您收到此错误：

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

然后加入本次活动的声明在清单中的<application>标签中应该修复它：

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