Ubuntu14.04 LTS (requires 64-bit long-term support version of LTS)
Jdk1.8
Kernel: android4.0

One: JDK

1. Unzip the JDK and get the path

2.
sudo vim /etc/environment
Modified to:

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/lhy/jdk/jdk1.8.0_45/bin"JAVA_HOME="/home/lhy/jdk/jdk1.8.0_45"CLASSPATH=".:/home/lhy/jdk/jdk1.8.0_45/lib"

3, Source/etc/environment

Two: Ubuntu configuration
Note the version of the JDK version and compiler gcc, g++,
Website configuration: http://source.android.com/source/initializing.html
Ubuntu14.04:

sudo apt-getInstall Bison g++-Multilib git gperf libxml2-utilsMake Python-networkxzlib1g-dev: I386 zip put the following error on the installation is here. sudo apt-getInstall G++sudo apt-getInstall GCC-multilibsudo apt-getInstall G++-4.4-multilibsudo apt-getInstall Flexsudo Apt-getInstall LIBNCURSES5-devsudo apt-getInstall LIB32NCURSES5-devsudo apt-getInstall Gawk (this is on the Internet to see what needs to be installed, I have not made mistakes in advance installation)

Error occurred:

The following packages have unsatisfied dependencies: g++-Multilib : dependencies: GCC-Multilib (>= 4:4.8.2-1ubuntu6) but it will not be installed                dependencies: g++ (>= 4:4.8.2-1ubuntu6) but it will not be installedE: the error cannot be corrected because you require certain packages to remain current, that is, they destroy the dependencies between software packages

Processing method:

sudo apt-get install g++sudo apt-get install gcc-multilib

Error occurred:

Workaround:

需要安装gcc、g++的multilib包，直接执行下面的命令，会自动安装g++、gcc的multilib包；    sudoapt-getinstallg++-4.4-multilib
