这里来介绍一下如何设定android的开发环境。
我们分为几个阶段:
1. linux基本环境设定
2. android apk 开发环境设定
3. android os 开发环境设定

首先，linux环境设定:

1. 安装 ubuntu version 10.04 LTS 64bit (以下是以ubuntu来举例说明)
1.1. 设定 eth0.
1.2. 设定 samba service. (这个是为了方便与windows共享档案用)

1.3. 最好执行 system / administration / update manager 将系统更新到最新.
2. 安装浏览器 google chrome. (也可以用内建的firefox)

3. 安装 ssh (方便用其他电脑连线进去作业)

安装指令: sudo apt-get install ssh
4. 安装中文输入法 gcin.

5.1. 设定 android sdk folder for eclipse.
5.2. 启动 android sdk manager and download necessary components.
6. 安装 android ndk (非必要步骤)

最后，安装 android os 开发环境

1. 安装必要元件.
参考资料: http://source.android.com/source/initializing.html    (key word: "Installing required packages")
安装指令: sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc
安装指令: sudo ln -s /usr/lib32/mesa/libGL.so.1 /usr/lib32/mesa/libGL.so
安装指令: sudo apt-get install sharutils    //for uudecode

2. 设定 USB Access 权限
参考资料: http://source.android.com/source/initializing.html (key word: "Configuring USB Access")
安装指令: sudo vim /etc/udev/rules.d/51-android.rules
add following lines:
----------------------------------------------------------
SUBSYSTEM=="usb", SYSFS{idVendor}=="vendor id here", MODE="0666"
SUBSYSTEM=="usb", SYSFS{idVendor}=="vendor id here", OWNER="user name here" GROUP="group name here"
----------------------------------------------------------
!!NOTE: This is known to work on both Ubuntu Hardy Heron (8.04.x LTS) and Lucid Lynx (10.04.x LTS).

3. 设定 ccache (加快 build image 速度)
参考资料: http://source.android.com/source/initializing.html (key word: "Setting up ccache")
安装指令: mkdir ~/data/ccache
安装指令: vim ~/.bashrc
add following lines at end of file:
----------------------------------------------------------
export USE_CCACHE=1
export CCACHE_DIR=~/data/ccache
----------------------------------------------------------

4. 设定开启档案最大值
安装指令: sudo vim /etc/security/limits.conf
add following lines at end of file:
----------------------------------------------------------
user_name_here      -       nofile          4096
root             -       nofile          4096
----------------------------------------------------------




其他实用的设定
1. format history command:
安装指令: vim ~/.bashrc
add following line at end of file:
----------------------------------------------------------
export HISTTIMEFORMAT="%F %T "
----------------------------------------------------------

2. format vim editor
安装指令: vim ~/.vimrc
add following lines
----------------------------------------------------------
set hlsearch            "高亮度反白
set backspace=2         "可随时用倒退键删除
set autoindent          "自动缩排
set ruler               "可显示最后一行的状态
set showmode            "左下角那一行的状态
set nu                  "可以在每一行的最前面显示行号啦！
set bg=dark             "显示不同的底色色调
syntax on               "进行语法检验，颜色显示。
