感谢支持
我们一直在努力

基于Ubuntu 14.04 LTS编译Android4.4.2源代码

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也可以,但10.04目前不支持了)
其他要求:空闲磁盘空间100G以上,代码部分接近10G,其他为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:如果编译Android4.4不能用OpenJDK,必须用Oracle JDK1.6,1.7目前是不支持的。
具体如何安装Oracle JDK,请参见我的另一篇单独的文章,[Ubuntu Linux下安装Oracle JDK] http://www.linuxidc.com/Linux/2015-01/112627.htm
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访问权限
将如下内容加入到/etc/udev/rules.d/51-android.rules文件中

# 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>”

然后执行如下命令,将上述文件中的username替换为你的用户名

4. 配置ccache
安装ccache并将export USE_CCACHE=1加入到~/.bashrc中。

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

==========================================
第二部分:源代码下载
==========================================
1. 安装repo
(1) 创建目录

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

(2) 下载repo工具
注:由于防火墙的原因,官方提供的链接无法使用,需替换为如下:
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) 增加可执行权限

$ chmod a+x ~/bin/repo

2. 初始化Repo客户端
(1)创建目录

$mkdir aosp
$cd aosp

(2) 初始化repo
注:后面可能出现网络错误,请先将如下内容加入到/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:如果是在虚拟机中执行,需要采用email验证的方式,详细参见参考资料[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”

修改aosp/.resp/manifest.xml,将fetch=”..”改为:
fetch=”https://android.googlesource.com/”

3. 下载源代码

$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:源代码编译
==========================================
1. 设置ccache
注:aosp为源代码根目录

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

2. 设置输出目录
略:由于我未分区,因此采用默认的out目录
3. 初始化编译环境

linuxidc@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
linuxidc@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

linuxidc@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

============================================
linuxidc@dubuntu1404:~/devenv/aosp$ make -j4

注:j4中的数字跟你的CPU个数和核数有关,详细参见参考资料[3].

整个编译过程,大约花了三个小时。编译成功后会在out目录下生成img文件。

5. 将img加载到物理机

(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

将如下部分加入~/.bashrc文件中:

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

然后保存执行”. .bashrc”使其生效。

(4) 以fastboot模式重启手机

$ adb reboot bootloader

此时手机会重启,呈现一个与往不同的fastboot界面

(5) 将编译的img刷到目标机

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

Device product is ‘tuna’.
Update requires ‘mako’.

(注:由于我的物理机三星I9250在lunch里没有对应的型号,因此会加载失败,这里这是记录过程)
===================================
如果需要编译其他版本,可执行如下步骤,这里选择虚拟机用的通用版本aosp_arm-eng。

$ cd aosp

编译完成,执行如下命令可以将您刚build好的ROM在模拟器里运行起来,第一次启动的时间可能比较长:

$ emulator &
注意:如果提示找不到emulator命令,可将如下环境变量重新初始化一遍(也就是每次重新进入系统运行的时候,都需要初始化一遍),lunch后面的参数要与你编译的ROM选项一致。

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