【中文标题】com.google.android.gms.ads.AdView 无法实例化

【英文标题】：com.google.android.gms.ads.AdView failed to instantiate

【问题描述】：

我是 android 和 admob 的新手。 我下载了 sdk ......导入了 play 服务库并完成了在 sdk 文档上写的所有事情。 但是当我添加 xml sn-p:

<com.google.android.gms.ads.AdView android:id="@+id/adView"
 android:layout_
 android:layout_
 ads:adUnitId="MY_AD_UNIT_ID"
 ads:adSize="BANNER"/>

我在错误日志中收到以下消息

。 我知道之前有人问过这个问题，但没有一个对我有用。 上述错误的错误日志：

另外，我已经从开普勒切换到 Eclipse Luna，这会导致问题吗？ 我的 xml 文件：

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_
android:layout_
 android:id="@+id/mainScreen"
 >
 <LinearLayout 
     android:layout_
     android:layout_
     android:layout_alignParentBottom="true">
      <com.google.android.gms.ads.AdView android:id="@+id/adView"
                     android:layout_
                     android:layout_
                     ads:adUnitId="_id"
                     ads:adSize="BANNER"/>   
</LinearLayout>
</RelativeLayout>

我也尝试以编程方式添加横幅。我收到以下错误：

描述资源路径位置类型 转换为 Dalvik 格式失败：无法执行 dex：多个 dex 文件定义 Lcom/google/ads/AdRequest$ErrorCode； myApp 未知的 Android 打包问题

编辑 我搜索了上述错误并在这里找到了解决方案https://***.com/a/14004090/2647040

现在它在以编程方式添加横幅时不会显示任何错误。 通过xml添加横幅时确实显示相同的错误错误，但现在在模拟器上显示广告。

【问题讨论】：

您正在测试的设备是否安装了 Google Play 服务？

是的，我确实安装了它。

【参考方案1】：

看起来您可能有两个 Admob 类的副本。当您尝试使用新的 Google Play 服务类时，您可能仍将旧的 admob sdk 作为应用程序库。

如果您有旧的 admob sdk 以及 Google Play 服务，则从您的 libs 文件夹中删除旧的 admob sdk 并清理您的项目，它应该可以解决错误。
