Admob广告：com.google.Androidgms。ads.AdView未能实例化

Question

Google Play服务位置：C：\用户\用户\文档\Eclipse\MyApp\libs

根据谷歌的教程，添加了正确的元标记、声明的活动和设置权限（全部经过双重检查）：https://developers.google.com/mobile-ads-sdk/docs/

还添加了重要的导入，并在xml中添加了横幅。。根据这里的另一个类似主题，还尝试将横幅设置为450dpx75dp。

也许这是proGuard的问题。就像你在评论中说的，它被禁用了，但是你应该尝试一些东西。这不是一个真正的答案，但是我必须向你展示一些代码。所以如果有人看到这个，请不要投反对票。

打开proguard-project.txt文件并将以下行放入其中：

      -keep public class com.google.android.gms.ads.** {
         public *;
       }

      -keep public class com.google.ads.** {
         public *;
       }

我知道，在某些情况下，混淆应用程序会导致此错误。值得一试。。。。
