在学习应用编程时，为了实现应用在后台对其它界面的控制，需要将应用的权限提高到系统级。
但提高到系统级的方法，其中一个就是放在 Android 源代码目录中进行编译；另一个方法已经试过，但安装失败。
开始一直想直接从 Google 的网站上获取 Android 源代码，但由于大陆对 Google 的封锁，导致无法获取到。大家都通过 VPN 来获取，但一般 VPN 是需要费用的。
后来才将获取 Android 源代码的方向转向别人下载好，打包传到网上的。
先后从 XX 云盘下载了 3 个 Android 源代码压缩包，分别是：
repo.tar.gz 12.2GB
WORKING_DIRECTORY.tar 12.4GB
android4.0.tar.gz 1.73GB
前两个还没有使用过，先使用 android4.0.tar.gz 进行了试验。
在 Ubuntu 中先解压 android4.0.tar.gz: tar -zxvf android4.0.tar.gz
安装 jdk-6u45-linux-i586.bin，从 Oracle 网站上下载，需要在 Oracle 注册。
获取 jdk-6u45-linux-i586.bin 下载网址的办法: google "jdk-6u45-linux" 得到的第一个搜索结果:
http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html
注意: 不用使用 Ubuntu 提供的 open-jdk 的版本。
安装过程:
(1) 赋予执行权限，在 terminal 中输入: chmod a+x jdk-6u45-linux-i586.bin
(2) 解压，在 terminal 中输入: ./jdk-6u45-linux-i586.bin
(3) 创建 jvm 目录，在 terminal 中输入: sudo mkdir /usr/lib/jvm
(4) 移动解压文件，在 terminal 中输入: sudo mv ~/AndroidSource/android4.0/jdk1.6.0_45 /usr/lib/jvm/jdk1.6.0_45
(5) 启用 jdk 6，在 terminal 中输入:
sudo ln -s -b /usr/lib/jvm/jdk1.6.0_45/jre/bin/java /etc/alternatives/java
sudo ln -s -b /usr/lib/jvm/jdk1.6.0_45/jre/bin/java /usr/bin/java
(6) 检验，在 terminal 中输入:java -version
结果应显示:
java version "1.6.0_45"
(7) 编辑配置文件，在 terminal 中输入: sudo vim /etc/profile
在文件末尾添加如下条目:
JAVA_HOME=/usr/lib/jvm/jdk1.6.0_45
export JRE_HOME=/usr/lib/jvm/jdk1.6.0_45/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
#set java environment
这里要根据自己的安装路径对以上内容进行修改！重启系统后java的环境就安装好了。
注: vim 操作指令，(1) Insert 按键;(2) : ; （3）! ; (4) w/q
开始编译 Android 源代码，进入目录: ~/AndroidSource/android4.0，依次输入如下指令:
#make installclean
#make clean
#source build/envsetup.sh
#lunch 选择版本号: lunch full-eng
1. full-eng
2. full_x86-eng
3. vbox_x86-eng
4. full_maguro-userdebug
5. full_tuna-userdebug
6. full_panda-eng
Which would you like [full-eng] 5
#make -j4 其中-j(n)表示用n核cpu编译
如果出错如下错误，按对应方法解决:
(1) Ubuntu bison：找不到命令
sudo apt-get install g++
(2) Ubuntu g++：找不到命令
sudo apt-get install bison
(3) /usr/bin/ld: cannot find -lz
详细信息如下:
host C: libpng <= external/libpng/pngwtran.c
host C: libpng <= external/libpng/pngwutil.c
host StaticLib: libpng (out/host/linux-x86/obj/STATIC_LIBRARIES/libpng_intermediates/libpng.a)
host Executable: aapt (out/host/linux-x86/obj/EXECUTABLES/aapt_intermediates/aapt)
/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/aapt_intermediates/aapt] 错误 1
解决方法:
更新了工具的安装，如下：
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
可以继续编译。
错误1:
编译过程中出现一次提示: 进程被杀掉的错误，并终止的现象。
当时没有记录具体的错误，重新编译就 OK 了。
------重新执行: make -j2
错误2:
t_intermediates/src -api out/target/common/obj/PACKAGING/public_api.txt -nodocs
make: *** 正在等待未完成的任务....
make: *** [out/target/common/docs/api-stubs-timestamp] 错误 45
解决方法(使用方法2):
(1) 网上一种解决方法(但我的 extenal 目录中没有 clearsilver 目录(有人说此方法适用于: Android 2.3))
是由于clearsilver在编译时如果检测到使用Java JDK 6，就使用64位编译。要避开此错误，需要修改下面四个文件：
external/clearsilver/cgi/Android.mk
external/clearsilver/java-jni/Android.mk
external/clearsilver/util/Android.mk
external/clearsilver/cs/Android.mk
把这四个Makefile中的下列语句注掉即可：
# This forces a 64-bit build for Java6
# Comment by Easwy
# LOCAL_CFLAGS += -m64
# LOCAL_LDFLAGS += -m64
然后在external/clearsilver目录中执行一下make clean，然后回到项目根目录，继续make即可。
(2) make clear/make update-api/make
(3) make: *** [out/target/common/docs/doc-comment-check-timestamp] 错误 45
解决方法：需要做个链接如下：
sudo ln -s /usr/lib/jvm/jdk1.6.0_45/bin/jar /bin/jar
sudo ln -s /usr/lib/jvm/jdk1.6.0_45/bin/java /bin/java
sudo ln -s /usr/lib/jvm/jdk1.6.0_45/bin/javac /bin/javac
sudo ln -s /usr/lib/jvm/jdk1.6.0_45/bin/javah /bin/javah
sudo ln -s /usr/lib/jvm/jdk1.6.0_45/bin/javadoc /bin/javadoc

挂载一个 20G 的空分区后编译 Android 4.0.1 的源代码，仍然出现: No space left on device。所以一狠心，将现在用的 Ubuntu 虚拟机删除了，重建一个 80G 的虚拟机。
使用 Ubuntu 10.04，安装后不做任何升级。
以下是操作过程中对硬盘剩余空间的记录:
(1) 80G 安装 Ubuntu 后剩余 69.7 GB
(2) 复制 android4.0.tar.gz 和 jdk-6u45-linux-i586.bin 后，解压: tar -zxvf android4.0.tar.gz 后剩余 61.4 GB
(3)准备好编译环境后(删除 android4.0.tar.gz 和 jdk-6u45-linux-i586.bin)，剩余空间 62.9 GB
开始编译 Android 4.0.1 源代码。
如果编译过程中出现错误，只要编译环境的配置是正确的，就不要试着去解决它。只需要简单的重新编译即可！编译成功后，剩余的空间是 51.1 GB。
编译 Android 4.0.1 源代码，至少需要 18.6G 的硬盘空间。
