ubuntu 12.04 x64编译 Android4.4遇到的问题
编译之前最好先把需要的包全装了
sudo apt-get install build-essential make gcc g++ libc6-dev texinfo libncurses-dev git-core gnupg flex bison zip curl ncurses-dev libsdl-dev zlib1g-dev ia32-libs libxml2-utils lzma1.
build/core/config.mk:365: *** Error: could not find jdk tools.jar, please install JDK6, which you can download from java.sun.com。 停止。我是配置了java 环境变量之后，使用 source /etc/profile使环境生效，然后直接make，就出现上面的问题，尽管在shell窗口输入 java javac等命令显示的刚才安装的jdk，这时试着把电脑注销启动之后就没问题了，应该是环境变量还未真正生效？
2.
build/core/java.mk:258: *** bin: Target java module does not define any source or resource files。 停止。删除android源码根目录下的bin目录，因为自己之前使用了eclipse导入该源码，eclipse便会生成这个目录，删除再make即可。

make: *** [out/host/linux-x86/obj/EXECUTABLES/validatekeymaps_intermediates/Main.o] 错误 1输入：
sudo apt-get install apt-file
sudo apt-file update
接着再输入 make，还是报与上面一样的错，网上查找查看链接，可以先不输入 sudp apt-file update。输入 apt-get install apt-file之后再输入命令：
apt-file search libz.so
显示：
lib32z1: /usr/lib32/libz.so.1
lib32z1: /usr/lib32/libz.so.1.2.3.3 lib32z1-dev: /usr/lib32/libz.so lsb-build-base3: /usr/lib/lsb3/libz.so zlib1g: /lib/libz.so.1 zlib1g: /lib/libz.so.1.2.3.3 zlib1g-dbg: /usr/lib/debug/lib/libz.so.1.2.3.3 zlib1g-dbg: /usr/lib/debug/usr/lib32/libz.so.1.2.3.3 zlib1g-dev: /usr/lib/libz.so于是使用 apt-get install 依次安装上面的模块，再执行make

136 错误
make: *** [out/host/common/obj/JAVA_LIBRARIES/doclava_intermediates/javalib.jar] 错误 41原来是我的jdk环境配置问题，见stackoverflow
我之前的环境配置是;
export JAVA_HOME=/usr/local/jdk1.6.0_45
export JRE_HOME=/usr/local/jdk1.6.0_45/jre
export CLASSPATH=.:$JAVA_HOME/lib/:$JRE_HOME/lib/:$CLASSPATH
export PATH=$JAVA_HOME/bin/:$JRE_HOME/bin/:$PATH要改为：
export JAVA_HOME=/usr/local/jdk1.6.0_45
export JRE_HOME=/usr/local/jdk1.6.0_45/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH注意二者的区别，改完后的 PATH和CLASSPATH之后的bin和lib后面均没有 “/”。

sudo apt-get install git
再次make，结果还是出现同样的错误
干脆把下面的环境都安装：
git
gnupg
flex
bison
gperf
build-essential
zip
curl
libc6-dev
x11proto-core-dev
g++-multilib
tofrodos
python-markdown
libxml2-utils
xsltproc一个一个安装，如果已经安装了，ubuntu会自己提示已经安装

启动模拟器
1.
emulator: ERROR: You did not specify a virtual device name, and the system
directory could not be found.
If you are an Android SDK user, please use '@<name>' or '-avd <name>'
to start a given virtual device (see -help-avd for details).
Otherwise, follow the instructions in -help-disk-images to start the emulator解决：
source build/envsetup.sh
lunch sdk-eng
然后再执行
emulator
编译内核
1.
ERROR: include/asm is a directory but a symlink was expected
make: *** [include/asm] 错误 1解决方法：
删除源码根目录下的include/asm，文件夹，问题解决。
kernel/include/asm 文件夹是内核编译过程中创建的，创建结果就是一个指向文件夹asm-arm的链接，表明该系统的平台是arm架构的，而编译系统内核之前，是没有asm这个链接的，所以，在编译过程中，创建该链接时文件名字与asm文件夹的名字发生冲突，报错了。
2.
使用自己编译的内核运行模拟器，结果
提示错误为：
root@lpchou-Lenovo-G450:/android4.4/kernel# emulator -kernel /android4.4/kernel/arch/arm/boot/zImage
emulator: WARNING: system partition size adjusted to match image file (550 MB > 200 MB)
Failed to load libGL.so
error libGL.so: cannot open shared object file: No such file or directory
Failed to load libGL.so
error libGL.so: cannot open shared object file: No such file or directory我是用的是 make goldfish_armv7_defconfig 命令来编译的啊。
报错解决输入命令：
sudo apt-get install libgl1-mesa-dev
再次运行模拟器，不会报上面的错了，但是模拟器还是黑屏。。。
网上搜索，对于android4.4及以后的版本，使用 goldfish2.6的没用，只有自己去下新的goldfish，于是下载了 goldfish3.4内核。

按照正确的方法在Android4.4上编译 goldfish3.4内核（编译内核还是挺快的），完成后，启动模拟器，如图：
可以看到Android version为 4.4的，而内核为自己编译的3.4.67版本。
