android stdio 安装后gradle 编译失败，设置代理不管用

1. 去掉代理

2 去掉build.gradle中的 google,与jcenter，替换为阿里云

//google()

//jcenter()

替换为

maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }

maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/' }

maven{ url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}
