下載最新Android代碼的方法
2021-09-09 14:09:53

??? 之前我是去Android官方網(wǎng)站下載最新Android代碼,但是這種方法需要FQ,而且有時(shí)候FQ又不太方便,今天我發(fā)現(xiàn)一個不錯的網(wǎng)站,是清華大學(xué)搞的,跟Android官方的代碼基本保持同步,而且下載方法跟Android官方的也類似。下面是網(wǎng)站地址:

https://mirrors.tuna.tsinghua.edu.cn/help/AOSP/

下面我簡單介紹一下幾種下載方法:

準(zhǔn)備工作

方法一

  • 下載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
  • 建立工作目錄
   1: mkdir WORKING_DIRECTORY
   2: cd WORKING_DIRECTORY
  • 初始化倉庫
   1: repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest
   2: ## 如果提示無法連接到 gerrit.googlesource.com,可以編輯 ~/bin/repo,把 REPO_URL 一行替換成下面的:
   3: REPO_URL = 'https://gerrit-google.tuna.tsinghua.edu.cn/git-repo'
  • 同步源碼樹
   1: repo sync

方法二 建立本地鏡像

重點(diǎn)說一下這種方法,這種方法首先在本地建立一個Andriod代碼的鏡像,第一次需要下載大量的代碼(我的占了120GB左右的空間),然后執(zhí)行類似方法一,不過這次的Android代碼源是在本地,所以速度很快。以后更新的時(shí)候,先更新本地Andriod代碼鏡像,再更新Android代碼。我用的就是這種方法,我的代碼鏡像是FQ的時(shí)候從Android官方下載的,所以每次更新Android代碼鏡像的時(shí)候都需要FQ,不方便。

步驟:

  • 下載 repo 工具和建立工作目錄 (參照方法一)

這里需要修改一下repo工具:

   1: REPO_URL = 'https://gerrit.googlesource.com/git-repo'

修改為:

   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
  • 同步源碼樹
   1: repo sync

然后,就可以從本地sync代碼了:

   1: repo init -u WORKING_DIR/mirror/platform/manifest.git
   2: repo sync

下面是Android官方的說明:

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 sync

Once 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 sync

Finally, 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 sync

?It'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鏡像

由于我最初的Android鏡像來自Android官方,需要FQ,所以需要作如下修改:

如果你之前已經(jīng)通過某種途徑獲得了 AOSP 的源碼(或者你只是 init 這一步完成后),你希望以后通過 TUNA 同步 AOSP 部分的代碼,只需要將 .repo/manifest.xml 把其中的 aosp 這個 remote 的 fetch 從 https://android.googlesource.com 改為 https://aosp.tuna.tsinghua.edu.cn/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"

同時(shí),修改 .repo/manifests.git/config,將

   1: url = https://android.googlesource.com/platform/manifest

更改為

   1: url = https://aosp.tuna.tsinghua.edu.cn/platform/manifest
   2: # 或 url = git://aosp.tuna.tsinghua.edu.cn/aosp/platform/manifest

?

完。
