java - Android Gradle错误不支持的ClassVersionError

Question

我正在尝试制作我的第一个应用程序(Hello World)并在手机上运行它，但是当我单击运行时，gradle返回此错误(我在此处对stackoverflow进行了研究，并试图关闭即时运行，但似乎没有就我而言):

以后的编辑:我认为这与Java版本有关，但是我不知道如何更新Android Studio？

后来edit2:我想通了，我在计算机上安装了较旧的jdk版本，并安装了最新的android studio，感谢您的帮助。我只需要安装最新的jdk版本(8)

Answer 1

在build.gradle(Module:app)中
原样:buildToolsVersion“24.0.0”
需:buildToolsVersion“23.0.3”
