1、安装jdk7
Ubuntu16.04的安装源已经默认没有openjdk7了，所以要自己手动添加仓库，如下：
$ sudo add-apt-repository ppa:openjdk-r/ppa
$ sudo apt-get update
安装openjdk-7-jdk
$ sudo apt-get install openjdk-7-jdk openjdk-7-jre
如果安装成功之后还是不能用可能有多个版本，执行如下命令选择正确的版本：
$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac
查看Java版本信息：
$ java -version
2、安装编译所需的依赖
以下提到的编译需要依赖的程序，请务必确认每个都安装成功：
sudo apt-get update
sudo apt-get install -y git flex bison gperf build-essential libncurses5-dev:i386
sudo apt-get install libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev g++-multilib
sudo apt-get install tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386
sudo apt-get install dpkg-dev libsdl1.2-dev libesd0-dev
sudo apt-get install git-core gnupg flex bison gperf build-essential
sudo apt-get install zip curl zlib1g-dev gcc-multilib g++-multilib
sudo apt-get install libc6-dev-i386
sudo apt-get install lib32ncurses5-dev x11proto-core-dev libx11-dev
sudo apt-get install lib32z-dev ccache
sudo apt-get install libgl1-mesa-dev libxml2-utils xsltproc unzip m4
如果安装过程中出现错误，务必逐个搜索解决方案，可能某些程序的版本有变动:
例如 :lib32z-dev 有可能需要安装：lib32z-dev：i386
编译过程中出现如下错误：
libnativehelper/JniInvocation.cpp:40: error: unsupported reloc 43
libnativehelper/JniInvocation.cpp:45: error: unsupported reloc 43
libnativehelper/JniInvocation.cpp:165: error: unsupported reloc 43

libnativehelper/JniInvocation.cpp:165: error: unsupported reloc 43

解决方法：
source_android代表你的android源码根目录
setp1:
vim <source_android>/art/build/Android.common_build.mk //修改第119行
修改前：
# Host.
ART_HOST_CLANG := false
ifneq ($(WITHOUT_HOST_CLANG),true)
# By default, host builds use clang for better warnings.
ART_HOST_CLANG := true
endif
修改后：
# Host.
ART_HOST_CLANG := false
ifneq ($(WITHOUT_HOST_CLANG),false)
# By default, host builds use clang for better warnings.
ART_HOST_CLANG := true
endif
setp2:
cp /usr/bin/ld.gold <source_android>/prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld
