膨胀类com.google.ads.AdView（InflateException）时出错

Question

I am trying to show a adview in my android application, but it shows an InflateException. This terminates the app and I cannot do anything.

Here is my logcat -

Answer 1

您需要将admob jar放入项目的libs文件夹中。

Answer 2

The same error appears to me and i solved with few simple steps.

You need to remove the appcombat dependency from your project. For removing right click your project->android->remove app combat and make sure you have selected android 4.2.2

And then import the google admob jar into your project.
