android studio ide fatal errors,Android Studio之Project Structure打开后显示异常踩坑记

最近把AS升级到3.4.2版本后，发现项目通过 File -> Project Structure 后打开的Project Structure窗口无法显示项目的配置信息(这个问题在AS旧的版本，3.4之前没出现)，如下图：

点击AS右下角的感叹号图标：

打开 IDE Fatal Errors 窗口

发现有报错信息，如下：

java.lang.IllegalStateException: Duplicate key 1.1.3，意思存在重复的key 1.13，然后就在项目中全局搜索，发现在项目中的build.gradle文件中存在重复的key 1.13，两个一样的

“ badgeview : '1.1.3', ”

解决方法：去掉一个“ badgeview : '1.1.3', ”就可以了。

以上仅仅是我项目的Project Structure显示异常的解决过程，希望对遇到此类问题的你有所帮助。当然也许你遇到的Project Structure显示异常的情况和我不同，如果你解决了，诚谢你分享和告知，以便帮助到需要帮助的人。😊😊😊
