Android Studio Sync 同步慢的问题

为什么同步慢

当你 Sync Project with Gradle File 是可能回下载一些 arr jar依赖包。而 Android Studio 默认是会去国外服务器仓库下载这些包。

解决办法

1. 翻 墙
2. 使用阿里云Maven中央仓库

在 Android Studio 内配置阿里云云效 Maven

关于我的灰色历史：
因为我现在使用 Unity开发 。之前一直在用国外仓库，因为我电脑没有VPNFQ软件，打包一个四五百兆的工程包，足足花了我四五小时。没办法，就让项目组的项目经理帮我打包。速度是真的要命。后来用国内的仓库速度简直不知道快了多少。

所以希望这篇博客可以帮助大家，少采坑，如果那里写错了也希望大家激励评论，谢谢。

所以我就简单介绍我是怎么用Unity 导出项目在AndroidStudio配置国内仓库。

首先我们要在C:\Users\admin\.gradle新建一个文件 init.gradle

allprojects {
    repositories {
        def ALIYUN_REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public'
        def ALIYUN_JCENTER_URL = 'http://maven.aliyun.com/nexus/content/repositories/jcenter'
        all {
            ArtifactRepository repo ->
                if (repo instanceof MavenArtifactRepository) {
                    def url = repo.url.toString()
                    if (url.startsWith('https://repo1.maven.org/maven2')) {
                        project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                        remove repo
                    }
                    if (url.startsWith('https://jcenter.bintray.com/')) {
                        project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                        remove repo
                    }
                }
        }
        maven { 
		    allowInsecureProtocol = true
            url ALIYUN_REPOSITORY_URL
            url ALIYUN_JCENTER_URL
        }
    }
}

然后在我们的项目内找到build.gradle文件

将google() 替换成阿里Maven对应的仓库maven {url "https://maven.aliyun.com/repository/google"}

将jcenter()替换成阿里Maven对应的仓库maven {url "https://maven.aliyun.com/repository/public"}

最后去掉这些代码 maven {url "https://maven.google.com"}

点击Android Studio右上角的Sync按钮。
