Answer 1

ad xml命名空间错误：

在GoogleAdMobAdsSdk-6.4.1.jar或更早版本中，您使用：

<com.google.ads.AdView

使用命名空间：

 xmlns:ads= "http://schemas.android.com/apk/lib/com.google.ads"

通过播放服务库在Google admob中，您可以使用：

<com.google.android.gms.ads.AdView

使用命名空间：

 xmlns:ads="http://schemas.android.com/apk/res-auto

Answer 2

尝试清理和重建项目。但错误很明显，它无法找到google play sdk jar中的com.google.ads.AdView类。如果您已更新到工具api 17+，则需要物理创建一个libs文件夹并将该jar放在该文件夹中，或在首选项中设置导出路径。

<com.google.ads.AdView android:id="@+id/adView"
                         android:layout_width="wrap_content"
                         android:layout_height="wrap_content"
                         ads:adUnitId="xyz"
                         ads:adSize="BANNER"

                         />

我还注意到您的adview调用看起来与新版本不同:(缺少.gms）

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

二进制XML文件行＃6：com.google.ads.AdView类错误
