下载 Android源码 + kernel源码 | 100%顺利完成
先照我博客A10专栏里面安装编译服务器描速一样，把源（/etc/apt/sources.list）备份并改好
step1、将Android-4.0.1_r1源码下载到/root/bin/android_source目录
>cd ～
>ls
>mkdir bin //若无bin目录，则创建
>cd bin
>touch repo
>chmod 777 repo
>curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo //若几次都提示：“(7) Failed to connect to 2404:6800:4005:c00::5b: 网络不可达”，那就用下面的网络路径
>curl http://php.webtutor.pl/en/wp-content/uploads/2011/09/repo > ~/bin/repo
==========================================================================================================================
以下这一部分可以跳过：
//使用浏览器登录https://android.googlesource.com/new-password, 使用自己到gmail帐号登录，点击网页上到“允许访问”，会得到如下信息：
Login for Git:
Username: git-XXX.gmail.com
Password: 1/w1m1wNjI6XD55_TdSWQhkYZwa7bz5PPWcOlHfAdzK10Staying Authenticated：
To stay authenticated by saving the password, append the following line to the ~/.netrc configuration file:
machine android.googlesource.com login git-wgembed.gmail.com password 1/w1m1wNjI6XD55_TdSWQhkYZwa7bz5PPWcOlHfAdzK10
machine android-review.googlesource.com login git-wgembed.gmail.com password 1/w1m1wNjI6XD55_TdSWQhkYZwa7bz5PPWcOlHfAdzK10>ls .netrc
>touch .netrc //若不存在该文件，新建一个
>chmod 777 .netrc
>gedit .netrc //粘贴以上拷贝到信息并保存
/*
以上写入两行machine到.netrc文件，以免下载过程中出现fatal: HTTP request failed
而将环境变量到临时修改和repo到连接地址初始化直接写在.sh文件中，这样就可以在多个终端页中同时下载时不必手动输入，这里到脚本保证下载失败后会在超时3秒后继续下载，直到下载完成为止
请注意repo init -u https://androdXXX/a/platrXXX，多了一个a目录，原本下载地址很难下载下来，这样就能顺利下载下来
多终端页中运行脚本会提示输入用户名和邮箱地址等信息，随便输入即可：
.repo/manifests/: discarding 60 commits
Your Name [root]: root
Your Email [root@vm.(none)]: [email protected]
Your identity is: root
is this correct [y/N]? y
Testing colorized output (for 'repo diff', 'repo status'):
black red green yellow blue magenta cyan white
bold dim ul reverse
Enable color display in this user account (y/N)? white
repo has been initialized in /root/bin/android_source
==========================================================================================================================
>mkdir android_source
>cd android_source
>touch sync_android_source.sh
>chmod 777 sync_android_source.sh
>gedit sync_android_source.sh
//将以下代码拷贝到该脚本并保存
注意：以 repo init -u git://codeaurora.org/platform/manifest.git -b gingerbread 替换下面的
repo init -u https://android.googlesource.com/a/platform/manifest -b android-4.0.1_r1#!/bin/bash
PATH=~/bin:$PATH
repo init -u https://android.googlesource.com/a/platform/manifest -b android-4.0.1_r1
repo sync
while [ $? != 0 ]; do
echo "***Error: sync failed, re-sync again***"
sleep 3
repo sync
done>./sync_android_source.sh
step2、将kernel3.4的源码下载到/root/bin/kernel
>cd bin/
>mkdir kernel
>cd kernel/
>git clone https://android.googlesource.com/kernel/common.git //等待下载完成
//导出自己需要的linux3.4版分支
>cd common/
>git branch -a
>git checkout -b android-3.4 remotes/origin/android-3.4
