Android 源码下载

在 Ubuntu 10.10 平台下Android源码下载步骤如下：

一、安装Java环境（假设已经下载了JDK安装文件）

#cp ./jdk-6u26-linux-i586.bin /usr/local/lib
#cd /usr/local/lib
#chmod +x jdk-6u26-linux-i586.bin
#./jdk-6u26-linux-i586.bin

export JAVA_HOME=/usr/local/lib/jdk.6.0_26
export JRE_HOME=/usr/local/lib/jdk.6.0_26/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=/usr/local/lib/jdk1.6.0_26/bin:$PATH

 

二、安装tools

$sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev sharutils

三、下载SDK源码（Android 2.3.1）

$ mkdir Android
$ cd Android
$ mkdir bin source
$ cd bin
$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo >repo
$ sudo chmod a+x repo
$ cd ~/android/source
$ ../bin/repo init -u https://android.googlesource.com/platform/manifest -b android-2.3.1_r1
$ ../bin/repo sync

如果要下载4.0.1_r1的话，只要将android-2.3.1_r1改为android-4.0.1_r1即可

四、下载Kernel源码（这里的kernel用于模拟器，具体的版本可根据SDK的版本来进行选择）

$ mkdir ~/android/kernel
$ cd kernel
$ git clone https://android.googlesource.com/kernel/goldfish.git
$ git branch -a
$ git checkout remotes/origin/android-goldfish-2.6.29

 五、编译Kernel

export PATH=$PATH:~/Android/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin
export ANDROID_PRODUCT_OUT=:~/Android/out/target/product/generic
修改comman目录下的Makefile:
ARCH ?= (SUBARCH)
CROSS_COMPILE?= 
改为：
ARCH ?= arm
CROSS_COMPILE?= arm-eabi-
$make goldfish_defconfig
$make
