Android Studio阿里镜像配置
如果你之前设置过 Android Studio 的 HTTP Proxy，然后又取消了代理设置，那么很有可能 Andoid Studio gradle 再次编译时仍然会走代理设置，造成依赖资源一直下载失败。
分为两种：
单独工程配置
1.删除 Android Studio 的代理设置
首先你需要确认你已经在 Settings -> Appearance&Behavior -> System Settings -> HTTP Proxy 中选中了 No Proxy。
然后找到项目根目录下的 gradle.properties 文件，打开查看该文件中是否有关于 proxy 设置（代理的地址和端口）的相关语句，删除这些内容，让该文件看起来大致是这个样子（如果你没有添加其他设置的话）：
最后，你需要找到你的另一个 gradle.properties 文件：C:\Users\Administrator.gradle\gradle.properties：
打开该文件，和上面的操作一样，删除与 proxy 设置相关的语句，让该文件的内容看起来大致是这样（如果你没有添加其他设置的话）：
2.让项目通过阿里云 maven jcenter 下载依赖资源
打开项目根目录下的 build.gradle（Project:项目名称一级的gradle），如下所示添加阿里 maven 库地址：

重新 SYNC 项目，编译时的资源下载一般就会如丝般顺滑了。

重启Android Studio 并clean rebuild 即可
