    基于Ubuntu 14.04 LTS编译Android4.4.2源代码
            Dennis Hu 2014-4-21
    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://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.

    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

    然后执行如下命令，将上述文件中的username替换为你的用户名。

    1. $sudo sed -i 's/username/dennis/g' /etc/udev/rules.d/51-android.rules  
    $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加入到~/.bashrc中。
    [plain] view plaincopyprint?
    1. $sudo apt-get install ccache 
    2. $source ~/.bashrc  
    $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
    [plain] view plaincopyprint?在CODE上查看代码片派生到我的代码片
    1. $ mkdir ~/bin 
    2. $ PATH=~/bin:$PATH  
    $ 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：
    [plain] view plaincopyprint?
    1. curl http://git-repo.googlecode.com/files/repo-1.12 > ~/bin/repo  
    curl http://git-repo.googlecode.com/files/repo-1.12 > ~/bin/repo
    (3) 增加可执行权限
    [plain] view plaincopyprint?
    1. $ chmod a+x ~/bin/repo  
    $ chmod a+x ~/bin/repo
    2. 初始化Repo客户端
    (1)创建目录
    [plain] view plaincopyprint?在CODE上查看代码片派生到我的代码片
    1. $mkdir aosp 
    2. $cd aosp  
    $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。
    [plain] view plaincopyprint?在CODE上查看代码片派生到我的代码片
    1. 74.125.71.82 www.googlesource.com 
    2. 74.125.31.82 android.googlesource.com 
    3. 203.208.46.172 cache.pack.google.com 
    4. 59.24.3.173 cache.pack.google.com  
    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！
    [plain] view plaincopyprint?
    1. $repo init -u https://android.googlesource.com/platform/manifest -b android-4.4.2_r2  
    $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：
    [plain] view plaincopyprint?
    1. git config --global user.email "you@example.com" 
    2. git config --global user.name "Your Name"  
    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
    [plain] view plaincopyprint?在CODE上查看代码片派生到我的代码片
    1. $repo sync  
    $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
    [plain] view plaincopyprint?在CODE上查看代码片派生到我的代码片
    1. $ cd aosp 
    2. $ prebuilts/misc/linux-x86/ccache/ccache -M 50G  
    $ 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
    [plain] view plaincopyprint?
    1. dennis@dubuntu1404:~/devenv/aosp$ . build/envsetup.sh  
    2. including device/samsung/manta/vendorsetup.sh

    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
    [plain] view plaincopyprint?
    1. $ sudo apt-get install android-tools-fastboot  
    $ 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：
    [plain] view plaincopyprint?
    1. export ANDROID_PRODUCT_OUT=/home/dennis/devenv/aosp/out/target/product/mako  
    export ANDROID_PRODUCT_OUT=/home/dennis/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
    [plain] view plaincopyprint?
    1. $ adb reboot bootloader  
    $ 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
    [plain] view plaincopyprint?
