Question

广告（智能横幅admob）最近在我的应用程序中消失了，尽管它们之前工作正常。

在Eclipse中使用virtual device运行应用时会显示以下消息：

无法接收广告（广告请求无效。）

当我打开main.xml文件时，会显示以下错误消息：

为标记LinearLayout
找到了意外的名称空间前缀“xmlns”

有谁知道我的代码出了什么问题？感谢。

Answer 1

删除来自嵌套LinearLayout的xmlns:android="http://schemas.android.com/apk/res/android"。只保留在根LinearLayout（第一个）中。因为Android.xml文件中的Android命名空间应该只声明一次。

Answer 2

将LinearLayout中的广告命名空间更改为

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

Answer 3

感谢Rebly亲爱的Shubham Shukla＆amp;雨披，

我已从嵌套的linearlayout中删除了这一行。

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

并仅将其保留在root linearlayout中，我将此行移至root linearlayout。

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

文件（main.xml）它已成为：
