ubuntu系统下载android源码

主要是记载一下下载源码过程中的一些问题和解决方法:

1. 
首先，按照http://source.android.com/source/initializing.html官方网站上得要求，配置了一个Ubuntu的源代码下载环境。
从Ubuntu官网上：http://releases.ubuntu.com/lucid/
下载了一个ubuntu-desktop-386的镜像，之后用虚拟机建了一个ubuntu的系统。
之后按照官网上得要求执行以下命令：
下载java SDK 6和安装一些需要的库
$ sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
$ sudo apt-get update
$ sudo apt-get install sun-java6-jdk
$ sudo apt-get install git-core gnupg flex bison gperf build-essential \
  zip curl zlib1g-dev libc6-dev libncurses5-dev x11proto-core-dev \
  libx11-dev libreadline6-dev libgl1-mesa-dev tofrodos python-markdown \
  libxml2-utils xsltproc
2.
 接着，配置要环境之后，按照http://source.android.com/source/downloading.html官网上得步骤下载源码。
创建bin目录，把bin目录加入到PATH环境变量中：
$ mkdir ~/bin
$ PATH=~/bin:$PATH
通过curl命令下载repo脚本：（通过这个脚本可以方便源码的操作）
$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
创建源码文件夹：
$ mkdir WORKING_DIRECTORY
$ cd WORKING_DIRECTORY
初始化repo：
$ repo init -u https://android.googlesource.com/platform/manifest
下载源码：
$ repo sync


问题出就出在repo sync这个命令上，首先在根据所要下载的版本初始化repo的时候，会在WORKING_DIRECTORY/.repo的目录下初始化一些版本的信息，包括这个版本的所包含的project的信息。
这些信息是存储在WORKING_DIRECTORY/.repo/manifest.xml结构化文件中。
之后repo sync 命令通过读取.repo中的版本信息，去源码库中下载。
由于网络的问题。repo sync 老是执行不完全，要么是time out, 要么就是访问出错。


在网上找了一些解决方法。
有一个方法不错，既然repo sync 是通过读取manifest.xml来下载源码的，那么可以通过脚本解析manifest.xml文件，获得project信息。
之后用repo sync projectname的方式，一个project一个project的下载。
下面是用到的脚本：
#!/bin/bash
declare -a projnames
tmp=`sed -n -e 's/<project //' -e 's/\/>//p' $1 | sed -e  's/path="//' -e 's/name="//' -e 's/"//g'`
projs=($(echo $tmp))
echo ${#projs[*]}

for((i=0; i<${#projs[*]}; i++))
do
  # projnames[j]=${projs[++i]}
#echo ${projs[++i]}
com=${projs[++i]}
echo "repo sync $com"
done


把这个脚本存成name.sh。
之后把manifest.xml文件作为参数传入即可。
命令：name.sh manifest.xml
