环境的建立：http://source.Android.com/source/initializing.html

这里我下载4.0.3 的源码：
repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.3_r1
下载的速度看个人的网络，这里我下了一天一夜。下载好之后就可以直接make -j4编译了，编译的时候用个大概3个小时，一旦按照以上两个连接编译的话，除了内存不够之外的应该没有什么问题，这里我遇到的是就是内存不够。
我机子是VMware + Ubuntu 11.04 2G内存 2G swap，后面编译的话会遇到类似如下错误：
Install: out/host/linux-x86/framework/dx.jar
Copy: dx (out/host/linux-x86/obj/EXECUTABLES/dx_intermediates/dx)
Install: out/host/linux-x86/bin/dx
target Dex: core
make: *** [out/target/common/obj/JAVA_LIBRARIES/core_intermediates/noproguard.classes-with-local.dex] 已杀死
主要原因是内存不够，解决办法可以是增加虚拟机的内存，或者是增加swap的大小。
以下是增加swap文件方法
1.创建一个 Swap 文件。
mkdir swap
cd swap
sudo dd if=/dev/zero of=swapfile bs=1024 count=100000
出现下列提示，上面命令中的 count 即代表swap文件大小。
记录了 100000+0 的读入
记录了 100000+0 的写出
102400000 字节 (102 MB) 已复制，0.74704 秒，137 MB/秒
把生成的文件转换成 Swap 文件
sudo mkswap swapfile
Setting up swapspace version 1, size = 102395 kB
no label, UUID=09fde987-5567-498a-a60b-477e302a988b
2.激活 Swap 文件。
sudo swapon swapfile
编译好之后设置环境变量 最后用emulator 运行
www @linux:~/android-4.0.3$ export PATH=$PATH:~/android-4.0.3/out/host/linux-x86/bin
www @linux:~/android-4.0.3$ export ANDROID_PRODUCT_OUT=~/android-4.0.3/out/target/product/generic
www @linux:~/android-4.0.3$ emulator
可以使用emulator -help 查看 命令的用法，例如
emulator -verbose 可以查看运行过程。
