Ubuntu9.10下获取Android源码
首先根据http://source.android.com/download网页上的描述可知，源码大概有2.1GB，需要6GB空间才能编译，因为我是在虚拟机上装的Ubuntu9.10，所以虚拟机至少要有10GB空间。粗体，下划线部分是我安装中遇到的一些问题，或者重点关注的地方
- Required Packages:
- Git 1.5.4 or newer and the GNU Privacy Guard.
-
- JDK 5.0, update 12 or higher. Java 6 is not supported, because of incompatibilities with @Override. //只能用JDK5，JDK6不能兼容@Override
-
- flex, bison, gperf, libsdl-dev, libesd0-dev, libwxgtk2.6-dev (optional), build-essential, zip, curl.
$ sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
- You might also want Valgrind, a tool that will help you find memory leaks, stack corruption, array bounds overflows, etc.//这个是帮你寻找内存漏洞，堆溢出，数组越界溢出的工具
$ sudo apt-get install valgrind
Ubuntu9.10的安装源已经没有JDK5了，所以需要用到9.04的安装源
修改/etc/apt/sources.list把9.04的源：
deb http://run.hit.edu.cn/ubuntu/ jaunty main restricted universe multiverse
deb-src http://run.hit.edu.cn/ubuntu/ jaunty main restricted universe multiverse
deb http://run.hit.edu.cn/ubuntu/ jaunty-updates main restricted universe multiverse
deb-src http://run.hit.edu.cn/ubuntu/ jaunty-updates main restricted universe multiverse
deb http://run.hit.edu.cn/ubuntu/ jaunty-backports main restricted universe multiverse
deb-src http://run.hit.edu.cn/ubuntu/ jaunty-backports main restricted universe multiverse
deb http://run.hit.edu.cn/ubuntu/ jaunty-security main restricted universe multiverse
deb-src http://run.hit.edu.cn/ubuntu/ jaunty-security main restricted universe multiverse
update之后，用sudo apt-get install sun-java5-jdk 即可像以往一样安装java 1.5
安装后的基本设置：
sudo update-alternatives --config java
sudo update-java-alternatives -s java-1.5.0-sun
这时候再用java -version就能看到java 1.5已经正常工作了
接下来就是安装repo
- Make sure you have a ~/bin directory in your home directory, and check to be sure that this bin directory is in your path:
$ cd ~
$ mkdir bin
$ echo $PATH - Download the repo script and make sure it is executable:
$ curl http://android.git.kernel.org/repo >~/bin/repo$ chmod a+x ~/bin/repo
初始化repo
- Create an empty directory to hold your working files:
$ mkdir mydroid
$ cd mydroid - Run repo init to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest:
$ repo init -u git://android.git.kernel.org/platform/manifest.git- If you would like to check out a branch other than "master", specify it with -b, like:
$ repo init -u git://android.git.kernel.org/platform/manifest.git -b cupcake
- If you would like to check out a branch other than "master", specify it with -b, like:
- When prompted, configure Repo with your real name and email address. If you plan to submit code, use an email address that is associated with a Google account.
repo initialized in /mydroid
Your client directory should now contain a .repo directory where files such as the manifest will be kept.

$ repo sync

The Android source files will be located in your working directory under their project names.
验证代码
Load the following public key into your GnuPG key database. The key is used to sign annotated tags that represent releases.
$ gpg --import
then paste the key(s) below, and press Control-D to end the input and process the keys. After importing the keys, you can verify any tag with

编译代码
To build the files, run make from within your working directory:
$ cd ~/mydroid
$ makeIf your build fails, complaining about a missing "run-java-tool", try setting the ANDROID_JAVA_HOME env var to $JAVA_HOME before making. E.g.,
$ export ANDROID_JAVA_HOME=$JAVA_HOME
