一，facets cannot be loaded.You can mark them as ignored to suppress this error notification

今天打开Android Studio，发现挂了（右边3.0变成那个死样子了，懵逼脸）...

打开项目也无法正常编译，报错：facets cannot be loaded.You can mark them as ignored to suppress this error notification。如下图：

经过一番折腾，发现是插件出了问题：
打开 File --> Other Settings --> Default Settings --> Plugins
发现有一些插件并没有勾选，具体是哪些我忘记了，大致如下：

重新勾选插件

二，Error:Failed to complete Gradle execution. Cause: Write access is allowed from event dispatch thread only

虽说第一个问题解决了，可是项目还是无法正常编译，于是又报了个新错误：
Error:Failed to complete Gradle execution. Cause: Write access is allowed from event dispatch thread only
图忘了截了，反正报的错就是上面这句话。
错误就是：Android Studio的SDK与电脑的JDK版本冲突，我们使用Android Studio自带的JDK即可。
打开 File --> Other Settings --> Default Project Structure --> SDK Location
把红框框里的勾选，就欧了...

惯例，奉上参考文章：
In android studio,cannot load 2 facets-unknown facet type:android and android-gradle
Error:Failed to complete Gradle execution. Cause: Write access is allowed from event dispatch thread only

睡觉了...
