我已将google.developers中的adView代码添加到mainactivity.java，因此它显示在屏幕顶部。是否有可能使用代码而不是xml文件将其与底部对齐？因为当我尝试使用xml布局文件执行此操作时，我收到此错误：
com.google.android.gms.ads.AdView failed to instantiate.
java.lang.VerifyError: Expecting a stackmap frame at branch target 57
Exception Details:

此外，当我在设备上运行它而没有在布局xml文件中指定adView时，在Logcat中它显示另一个错误，但一切似乎都正常（广告显示）。
07-28 19:20:59.667: E/GooglePlayServicesUtil(21076): The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.
我的问题有解决办法吗？
答案 0 :(得分：0)
查看您如何导入Google Play服务。我猜你有某种.jar，没有引用库。 .jar不能打包资源，因此找不到它们。 检查this教程，“在IDE中安装Play服务”和“创建Android项目”
