Windows下载AOSP

news2025/11/1 6:00:28

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

在这里插入图片描述

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 call

version = "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*
