环境准备：

基本环境：ubuntu-14.04-desktop-64bit LTS(裸机或者Windows下虚拟机安装均可，12.04也能够，但10.04眼下不支持了)

其它要求：空暇磁盘空间100G以上，代码部分接近10G，其它为git和编译中间和目标文件准备

==========================================

第一部分：环境初始化

==========================================

1. 安装Oracle JDK

注意：假设编译Android4.4不能用OpenJDK。必须用Oracle JDK1.6。1.7眼下是不支持的。

具体怎样安装Oracle JDK，请參见我的还有一篇单独的文章。[Ubuntu Linux下安装Oracle JDK]?http://blog.csdn.net/gobitan/article/details/24322561.

2. 安装必备工具软件

注意：这里与官方的有个包不同，官方的包会报错.

$sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dri:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386 dpkg-dev
$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

3. 配置USB訪问权限

将例如以下内容增加到/etc/udev/rules.d/51-android.rules文件里

# adb protocol on passion (Nexus One)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e12", MODE="0600", OWNER="<username>"
# fastboot protocol on passion (Nexus One)
SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", ATTR{idProduct}=="0fff", MODE="0600", OWNER="<username>"
# adb protocol on crespo/crespo4g (Nexus S)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e22", MODE="0600", OWNER="<username>"
# fastboot protocol on crespo/crespo4g (Nexus S)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e20", MODE="0600", OWNER="<username>"
# adb protocol on stingray/wingray (Xoom)
SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", ATTR{idProduct}=="70a9", MODE="0600", OWNER="<username>"
# fastboot protocol on stingray/wingray (Xoom)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="708c", MODE="0600", OWNER="<username>"
# adb protocol on maguro/toro (Galaxy Nexus)
SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", ATTR{idProduct}=="6860", MODE="0600", OWNER="<username>"
# fastboot protocol on maguro/toro (Galaxy Nexus)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e30", MODE="0600", OWNER="<username>"
# adb protocol on panda (PandaBoard)
SUBSYSTEM=="usb", ATTR{idVendor}=="0451", ATTR{idProduct}=="d101", MODE="0600", OWNER="<username>"
# adb protocol on panda (PandaBoard ES)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="d002", MODE="0600", OWNER="<username>"
# fastboot protocol on panda (PandaBoard)
SUBSYSTEM=="usb", ATTR{idVendor}=="0451", ATTR{idProduct}=="d022", MODE="0600", OWNER="<username>"
# usbboot protocol on panda (PandaBoard)
SUBSYSTEM=="usb", ATTR{idVendor}=="0451", ATTR{idProduct}=="d00f", MODE="0600", OWNER="<username>"
# usbboot protocol on panda (PandaBoard ES)
SUBSYSTEM=="usb", ATTR{idVendor}=="0451", ATTR{idProduct}=="d010", MODE="0600", OWNER="<username>"
# adb protocol on grouper/tilapia (Nexus 7)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e42", MODE="0600", OWNER="<username>"
# fastboot protocol on grouper/tilapia (Nexus 7)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e40", MODE="0600", OWNER="<username>"
# adb protocol on manta (Nexus 10)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee2", MODE="0600", OWNER="<username>"
# fastboot protocol on manta (Nexus 10)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee0", MODE="0600", OWNER="<username>"

然后运行例如以下命令，将上述文件里的username替换为你的用户名。

$sudo sed -i ‘s/username/dennis/g‘ /etc/udev/rules.d/51-android.rules

4. 配置ccache

安装ccache并将export USE_CCACHE=1增加到~/.bashrc中。

$sudo apt-get install ccache
$source ~/.bashrc

==========================================

第二部分：源码下载

==========================================?

1. 安装repo

(1) 创建文件夹

$ mkdir ~/bin
$ PATH=~/bin:$PATH

(2) 下载repo工具

注：因为防火墙的原因。官方提供的链接无法使用。需替换为例如以下：

官方的为curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

可用的：

curl http://git-repo.googlecode.com/files/repo-1.12 > ~/bin/repo

(3) 增加可运行权限

$ chmod a+x ~/bin/repo

2. 初始化Repoclient

(1)创建文件夹

$mkdir aosp
$cd aosp

(2) 初始化repo

注：后面可能出现网络错误，请先将例如以下内容增加到/etc/hosts中然后做后面的步骤。

74.125.71.82 www.googlesource.com
74.125.31.82 android.googlesource.com
203.208.46.172 cache.pack.google.com
59.24.3.173 cache.pack.google.com

至于为什么要出现网络错误，你懂的！

$repo init -u https://android.googlesource.com/platform/manifest -b android-4.4.2_r2

注意：假设是在虚拟机中运行。须要採用email验证的方式，具体參见參考资料[2].

设置git的用户名和邮件地址。将您的真实email地址和name替换了：

git config --global user.email "you@example.com"
git config --global user.name "Your Name"

改动aosp/.resp/manifest.xml，将fetch=".."改为：

fetch="https://android.googlesource.com/"

3. 下载源码

$repo sync

注意：系统可能会提示你升级repo，最好不要升级，除非你有十足信息解决升级后的一系列问题。

好了。慢慢等吧，短则数小时。长则几天几夜！

我花了5个小时

==========================================

第三部分：源码编译?

==========================================

1.?设置ccache

注：aosp为源码根文件夹

$ cd aosp
$ prebuilts/misc/linux-x86/ccache/ccache -M 50G

2. 设置输出文件夹

略：因为我未分区，因此採用默认的out文件夹

3. 初始化编译环境

dennis@dubuntu1404:~/devenv/aosp$ . build/envsetup.sh 
including device/samsung/manta/vendorsetup.sh
including device/generic/mips/vendorsetup.sh
including device/generic/armv7-a-neon/vendorsetup.sh
including device/generic/x86/vendorsetup.sh
including device/lge/mako/vendorsetup.sh
including device/lge/hammerhead/vendorsetup.sh
including device/asus/tilapia/vendorsetup.sh
including device/asus/deb/vendorsetup.sh
including device/asus/grouper/vendorsetup.sh
including device/asus/flo/vendorsetup.sh
including sdk/bash_completion/adb.bash
dennis@dubuntu1404:~/devenv/aosp$

4. 选择编译目标包

注：目标包的选择跟你的硬件有关。我这里选择9，mako

dennis@dubuntu1404:~/devenv/aosp$ lunch
You‘re building on Linux
Lunch menu... pick a combo:
     1. aosp_arm-eng
     2. aosp_x86-eng
     3. aosp_mips-eng
     4. vbox_x86-eng
     5. aosp_manta-userdebug
     6. mini_mips-userdebug
     7. mini_armv7a_neon-userdebug
     8. mini_x86-userdebug
     9. aosp_mako-userdebug
     10. aosp_hammerhead-userdebug
     11. aosp_tilapia-userdebug
     12. aosp_deb-userdebug
     13. aosp_grouper-userdebug
     14. aosp_flo-userdebug
Which would you like? [aosp_arm-eng] 9
============================================
PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=4.4.2
TARGET_PRODUCT=aosp_mako
TARGET_BUILD_VARIANT=userdebug
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=

TARGET_ARCH_VARIANT=armv7-a-neon
TARGET_CPU_VARIANT=krait

HOST_OS_EXTRA=Linux-3.13.0-24-generic-x86_64-with-Ubuntu-14.04-trusty
HOST_BUILD_TYPE=release
BUILD_ID=KVT49L
OUT_DIR=out
============================================
dennis@dubuntu1404:~/devenv/aosp$ make -j4

注：j4中的数字跟你的CPU个数和核数有关。具体參见參考资料[3].

整个编译过程，大约花了三个小时。编译成功后会在out文件夹下生成img文件。

5. 将img载入到物理机

(1) 将手机用USB数据线连接到机器

(2) 安装fastboot工具

$ sudo apt-get install android-tools-fastboot

(3)?设置ANDROID_PRODUCT_OUT环境变量

将例如以下部分增加~/.bashrc文件里：

export ANDROID_PRODUCT_OUT=/home/dennis/devenv/aosp/out/target/product/mako

然后保存运行". .bashrc"使其生效。

(4) 以fastboot模式重新启动手机

$ adb reboot bootloader

此时手机会重新启动，呈现一个与往不同的fastboot界面

(5) 将编译的img刷到目标机

dennis@dubuntu1404:~/devenv/aosp/out$ fastboot flashall -w
--------------------------------------------
Bootloader Version...: PRIMEMD04
Baseband Version.....: I9250XXLJ1
Serial Number........: 0146A0D00600900B
--------------------------------------------

FAILED
Device product is ‘tuna‘.
Update requires ‘mako‘.
finished. total time: 0.035s

(注：因为我的物理机三星I9250在lunch里没有相应的型号，因此会载入失败，这里这是记录过程)

===================================

假设须要编译其它版本号。可运行例如以下步骤，这里选择虚拟机用的通用版本号aosp_arm-eng。

$ cd aosp
dennis@dubuntu1404:~/devenv/aosp$ . build/envsetup.sh
including device/samsung/manta/vendorsetup.sh

including device/lge/hammerhead/vendorsetup.sh
including device/asus/tilapia/vendorsetup.sh
including device/asus/deb/vendorsetup.sh
including device/asus/grouper/vendorsetup.sh
including device/asus/flo/vendorsetup.sh

编译完毕，运行例如以下命令能够将您刚build好的ROM在模拟器里运行起来，第一次启动的时间可能比較长：

$ emulator &

注意：假设提示找不到emulator命令，可将例如以下环境变量又一次初始化一遍(也就是每次又一次进入系统运行的时候，都须要初始化一遍)，lunch后面的參数要与你编译的ROM选项一致。

$. build/envsetup.sh
$lunch aosp_arm-eng
