添加 cordova admob pro 后 Ionic 3 构建失败

Ionic 3 build failed after adding cordova admob pro

在尝试 AdMob Free plugin I found that is no longer working because the developer is not maintaining it or updating it since a while ago. so I moved to AdMob Pro 之后,我试图在我的 ionic 3 应用程序中实施 admob。 但是当我添加这个插件时,应用程序构建失败。 以下是错误:

* What went wrong:
Execution failed for task ':app:transformClassesWithDexBuilderForDebug'.

问题是由最新的cordova android版本(7.0.0)引起的,通过将应用程序中的android平台降级到6.4.0

解决了这个问题
