配置Android Studio

　　1.去gradle官网下载gradle，gradle的版本可以在C:\Program Files\Android\Android Studio\gradle下看到

2.新建一个项目，退出后把下载好的gradle-all zip包放进C:\Users\***\.gradle\wrapper\dists\gradle-4.1-all\bzyivzo6n839fup2jbap0tjew

3.启动Android Studio，在Configurations里下载SDK，要下载26.6，不然会有gradle sync fail

4.新建项目后，编辑.gitignore文件，加入下面的配置
