1、下载gradle

http://gradle.android-studio.org/

2、解压

3、配置环境变量。配置GRADLE_HOME到你的gradle根目录当中，然后把%GRADLE_HOME%/bin（linux或mac的是$GRADLE_HOME/bin）加到PATH的环境变量，配置完成之后，运行gradle -v，检查一下是否安装无误

4、AS配置gradle路径

 Settings >  Gradle >Gradle home path

5、SDK Manager升级开发库，android.support.Repository android.support.library

6、配置工程gradle和gradle plugin版本

project structure > project
