您的错误是：

java.lang.ClassNotFoundException: com.google.ads.AdView 

您是否已将Google Play服务正确添加到您的应用程序中

在你的应用程序/build.gradle中

你需要

dependencies {
     compile 'com.google.android.gms:play-services:5.0.77'
}

这在你的舱单上

 <meta-data android:name="com.google.android.gms.version"
       android:value="@integer/google_play_services_version" />

详细说明如下：

以下是admob的解释：
