## 二、报错原因 ##

Android项目版本是3.5.0，支持的Java版本为JDK1.8，而Android Studio版本是4.0.1，默认使用Java11，导致冲突。正确的解决方法就是单独设置Android项目的JDK路径。

## 三、解决方法 ##

1、[安装和配置好JDK1.8][JDK1.8]

![在这里插入图片描述][36ff25a1be594daa812c0cd91863a36c.png]

2、File——>Project Structure，可以看到当前项目的插件版本和Gradle版本信息。

3、在SDK Location的JDK Location中，选择你刚刚配置好的JAVA\_HOME，然后Apply——>OK。

> 古人认为人世祸福的发生与人们的善恶行为有着必然的的因果联系，祸福不是毫无缘由地降临在世人身上，人的善恶行为才是自身得祸得福的直接诱因。即使不现报在自己身上，也会报应在自己的后代身上。善有善报恶有恶报，所以人们不可不谨慎行事。
