该应用程序正常工作，但广告未展示！

Answer 1

您可以选中此link

  

它只是说您的代码是正确的。问题是AdMob确实   并非总是有一个广告可为每个请求返回。这可能发生   特别是如果您刚刚注册了AdMob发布商ID，   新ID开始之前需要花费一些时间和多个请求   返回广告。

等待一段时间可能是您刚刚创建了广告ID，但是如果不是这样的话 然后尝试更改应用程序包名称，即应用程序ID

如何更改Android应用包名称？

1. 要更改android应用的程序包名称，请转到“项目”窗口， 右键单击该应用，然后选择“打开模块设置”，
2. 将出现一个新窗口，在窗口中选择“风味”选项卡。 这是我们将更改应用程序包名称的地方，即 application id 重命名为任何内容，只需遵循语法

Answer 2

我的问题通过以下方法更改了软件包名称来解决：

1-右键单击项目

2- android工具

3-重命名应用程序包

检查清单以确保软件包名称已更改

然后：

项目--->清洁

Answer 3

实际上我无法理解该解决方案，如果您在代码中更改程序包名称，则还应该在播放控制台中更改该应用程序，因为Google希望所有发行版都具有相同的程序包名称。您是否在控制台中创建了新应用？ @Sh R S

Answer 4

您只需要等待3-5天。

Answer 5

如果您收到此错误代码3 ，则您的代码是正确的。问题是AdMob并非总是有一个广告可为每个请求返回。 ...您的填充率较低的另一个原因是您没有启用AdSense补余，或者您滤除了一些广告。检查您的应用设置，看是否是这种情况
