一、前言

• 参考 Android源码开发者网站 搭建AOSP环境

二、搭建源码开发环境

1.下载安装虚拟机和ubuntu14.04 镜像

下载并安装虚拟机,配置虚拟机内存8192M,150G磁盘空间,导入ubuntu14.04 镜像,启动虚拟机.

• VMware虚拟机下载

• Ubuntu 14.04.5 Desktop (64-bit) 种子下载

2.安装openjdk

• 查看源

   $ sudo gedit /etc/apt/sources.list
  

• 修改源,将sources.list里面的内容全部替换为以下内容

    deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
    deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
    deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
    deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
    deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
    deb-src  http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
  

• 更新源

  $ sudo apt-get update
  

• 安装openjdk-7-jdk

  $ sudo apt-get install openjdk-7-jdk
  

3. 安装所需软件包

  $  sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libxml2-utils xsltproc unzip

4. 配置USB权限

  $  wget -S -O - http://source.android.com/source/51-android.rules | sed "s/<username>/$USER/" | sudo tee >/dev/null /etc/udev/rules.d/51-android.rules; sudo udevadm control --reload-rules

• 列出USB设备 查看厂商编码

  $  lsusb 
  

三、下载源码

1.创建目录

$ mkdir bin
$ mkdir -p AOSP/android6.0

2.下载repo工具

$ curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo > ~/bin/repo
$ chmod a+x bin/repo

3.配置Git

$ cd  AOSP/android6.0
$ git config --global user.name "YourName"
$ git config --global user.email "you@example.com"

4.初始化repo

• 1.编辑bashrc文件

  $ vi ~/.bashrc
  

• 2.末尾插入配置

  PATH=~/bin:$PATH
  export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/'
  

• 3.退出重新打开

  $ exit
  $ cd AOSP/android6.0/
  

• 4.执行repo初始化

  repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-6.0.1_r78
  

5.下载代码

   $ repo sync

下载完成 源码目录

本人10M/s下载速度花费了3小时左右的时间

四、校验源码

1.导入公钥

   $ cd /AOSP/android6.0/build/
   $ gpg --import

公钥如下

2.输入完公钥之后不要执行回车等其他操作,直接执行Ctrl+D

3.查看所有版本,找到自己下载的版本号

$ git tag 

4.校验,签名输出的信息一致说明代码完整并没有被篡改!

$ git tag -v android-6.0.1_r78

校验完整性

至此源码下载完毕!
