Windows下载AOSP

关于repo

repo只是谷歌做的，方便下载安卓源码的工具，本质上是对下载清单进行批量处理，然后使用git克隆。
在windows上下载源码只需要自己处理即可。

具体做法

首先使用git克隆安卓源码清单

git clone https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest

随后进入manifest目录，查看所有tag

git tag

tag名就是安卓源码的版本，选择你要的版本，记下来。例如android-13.0.0_r9
随后切换分支

git checkout android-13.0.0_r9

在这里插入图片描述
记住文件夹中的default.xml的路径
以上操作完成了清单的下载，接下来我们只需要执行按清单下载的操作即可。
我提供两个我编写的脚本，一个python环境，一个golang环境。
注意：该脚本不支持断点续传，如需使用，请保持网络环境良好或自行修改脚本。

Python环境

该Python下载脚本仅支持单线程下载，不过git仍可以跑满你的网速

import xml.dom.minidom
import os
from subprocess import callversion = "android-13.0.0_r9"# 1. 源码要保存的路径
rootdir = "D:/AOSP/"+version# 2. git 的路径
git = r"C:\Program Files\Git\cmd\git.exe"# 3. default.xml 的路径
dom = xml.dom.minidom.parse(r"D:\AOSP\manifest\default.xml")
root = dom.documentElement# 4. 只支持单一镜像源
prefix = git + " clone https://aosp.tuna.tsinghua.edu.cn/"
suffix = ".git"if __name__ == '__main__':if not os.path.exists(rootdir):os.mkdir(rootdir)for node in root.getElementsByTagName("project"):os.chdir(rootdir)d = node.getAttribute("path")last = d.rfind("/")if last != -1:d = rootdir + "/" + d[:last]if not os.path.exists(d):os.makedirs(d)os.chdir(d)cmd = prefix + node.getAttribute("name") + suffix# 单线程下载call(cmd)

Golang环境

该golang脚本支持从多个镜像站并发下载，可限制每个镜像站同时下载的线程个数，以及总线程个数。
注意： * 总线程个数应小于等于各个镜像站线程个数相加*

package mainimport ("sync"
)type Resource struct {Url  stringLock chan struct{}
}type ResourcePool struct {resources []*Resourcecond      *sync.Cond
}func NewResourcePool(list []*Resource) *ResourcePool {pool := &ResourcePool{cond: sync.NewCond(&sync.Mutex{}),}pool.resources = listreturn pool

}func (pool ResourcePool) ReleaseResource(resource *Resource) {<-resource.Lockpool.cond.Signal()
