之前我是去Android官方网站下载最新Android代码,但是这种方法需要FQ,而且有时候FQ又不太方便,今天我发现一个不错的网站,是清华大学搞的,跟Android官方的代码基本保持同步,而且下载方法跟Android官方的也类似。下面是网站地址:
https://mirrors.tuna.tsinghua.edu.cn/help/AOSP/
下面我简单介绍一下几种下载方法:
准备工作
方法一
- 下载repo工具
1: mkdir ~/bin
2: PATH=~/bin:$PATH
3: curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
4: chmod a+x ~/bin/repo
- 建立工作目录
1: mkdir WORKING_DIRECTORY
2: cd WORKING_DIRECTORY
- 初始化仓库
1: repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest
2: ## 如果提示无法连接到 gerrit.googlesource.com,可以编辑 ~/bin/repo,把 REPO_URL 一行替换成下面的:
3: REPO_URL = 'https://gerrit-google.tuna.tsinghua.edu.cn/git-repo'
- 同步源码树
1: repo sync
方法二 建立本地镜像
重点说一下这种方法,这种方法首先在本地建立一个Andriod代码的镜像,第一次需要下载大量的代码(我的占了120GB左右的空间),然后执行类似方法一,不过这次的Android代码源是在本地,所以速度很快。以后更新的时候,先更新本地Andriod代码镜像,再更新Android代码。我用的就是这种方法,我的代码镜像是FQ的时候从Android官方下载的,所以每次更新Android代码镜像的时候都需要FQ,不方便。
步骤:
- 下载
repo
工具和建立工作目录 (参照方法一)
这里需要修改一下repo工具:
将
1: REPO_URL = 'https://gerrit.googlesource.com/git-repo'
修改为:
1: REPO_URL = 'https://gerrit-google.tuna.tsinghua.edu.cn/git-repo'
- 初始化
1: repo init -u https://aosp.tuna.tsinghua.edu.cn/mirror/manifest --mirror
- 同步源码树
1: repo sync
然后,就可以从本地sync代码了:
1: repo init -u WORKING_DIR/mirror/platform/manifest.git
2: repo sync
下面是Android官方的说明:
Using a local mirror
When using several clients, especially in situations where bandwidth is scarce, it is better to create a local mirror of the entire server content, and to sync clients from that mirror (which requires no network access). The download for a full mirror is smaller than the download of two clients, while containing more information.
These instructions assume that the mirror is created in /usr/local/aosp/mirror. The first step is to create and sync the mirror itself. Notice the --mirror flag, which can be specified only when creating a new client:
$ mkdir -p /usr/local/aosp/mirror $ cd /usr/local/aosp/mirror $ repo init -u https://android.googlesource.com/mirror/manifest --mirror $ repo syncOnce the mirror is synced, new clients can be created from it. Note that it's important to specify an absolute path:
$ mkdir -p /usr/local/aosp/master $ cd /usr/local/aosp/master $ repo init -u /usr/local/aosp/mirror/platform/manifest.git $ repo syncFinally, to sync a client against the server, the mirror needs to be synced against the server, then the client against the mirror:
$ cd /usr/local/aosp/mirror $ repo sync $ cd /usr/local/aosp/master $ repo syncIt's possible to store the mirror on a LAN server and to access it over NFS, SSH or Git. It's also possible to store it on a removable drive and to pass that drive around between users or between machines.
更新本地Android镜像
由于我最初的Android镜像来自Android官方,需要FQ,所以需要作如下修改:
如果你之前已经通过某种途径获得了 AOSP 的源码(或者你只是 init 这一步完成后),你希望以后通过 TUNA 同步 AOSP 部分的代码,只需要将 .repo/manifest.xml
把其中的 aosp 这个 remote 的 fetch 从 https://android.googlesource.com
改为 https://aosp.tuna.tsinghua.edu.cn/
或 git://aosp.tuna.tsinghua.edu.cn/aosp
。
1: <manifest>
2:
3: <remote name="aosp"
4: - fetch="https://android.googlesource.com"
5: + fetch="https://aosp.tuna.tsinghua.edu.cn" 或 "git://aosp.tuna.tsinghua.edu.cn/aosp"
6: review="android-review.googlesource.com" />
7:
8: <remote name="github"
同时,修改 .repo/manifests.git/config
,将
1: url = https://android.googlesource.com/platform/manifest
更改为
1: url = https://aosp.tuna.tsinghua.edu.cn/platform/manifest
2: # 或 url = git://aosp.tuna.tsinghua.edu.cn/aosp/platform/manifest
完。
