Android源码编译

在编译源码之前需要做一些准备操作, 详细步骤如下:

1. 安装JDK, google官方要求编译2.3源码需要JDK1.6.

1). 下载JDK1.6, 下载地址:http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html、http://download.oracle.com/otn/java/jdk/6u45-b06/jdk-6u45-linux-x64.bin
2). 创建目录.
1
sudo mkdir /usr/java
3). 在文件系统中右击上面的创建的文件夹，选择“以管理员权限打开”，然后把下载好的jdk-6u45-linux-x64.bin拖动到/usr/java目录中

4). 添加可执行权限.

1	sudo chmod 755 /usr/java/jdk-6u45-linux-x64.bin

5). 解压.

1 2	cd /usr/java sudo ./jdk-6u45-linux-x64.bin

6). 配置环境变量.

2
3

export JAVA_HOME=/usr/java/jdk1.6.0_45
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

7). 验证是否成功.
1
java -version

2. 安装其他编译时依赖的软件.

sudo apt-get install gnupg
sudo apt-get install flex
sudo apt-get install bison
sudo apt-get install gperf
sudo apt-get install zip
sudo apt-get install curl
sudo apt-get install build-essential
sudo apt-get install libesd0-dev
sudo apt-get install libwxgtk2.8-dev
sudo apt-get install libsdl-dev
sudo apt-get install lsb-core
sudo apt-get install lib32readline-gplv2-dev
sudo apt-get install g++-multilib
sudo apt-get install lib32z1-dev
sudo apt-get install libswitch-perl

安装注意事项：

3. 开始编译, 在源码的目录下, 执行一下命令:

1
2
3

cd ~/android_source
make clean(如果之前有编译过，则需要调用这个命令)
make

注意: ubuntu自带的源中速度比较慢, 有些软件找不到, 所以需要修改为国内的源, 修改源步骤如下:

1). 备份ubuntu自带的源.

1	sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

2). 修改源文件.
1
sudo gedit /etc/apt/sources.list

3). 这时会弹出一个文本编辑框, 先删除所有内容, 然后把以下内容拷贝进去, 并保存.

4). 保存之后, 更新数据源.
1
sudo apt-get update
