在Ubuntu 14.04(64bit)上搭建Android编译环境（通用版）

1. update package list

$ sudo apt-get update

2. install required packages

$ sudo apt-get install git gnupg flex bison gperf

$ sudo apt-get install build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \ libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev

$ sudo apt-get install g++-multilib mingw32 tofrodos python-markdown libxml2-utils \  xsltproc zlib1g-dev:i386 gawk

3. install JDK

# download jdk-6u45-linux-x64.bin (from Sun official website: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html)

# install JDK

$ sudo mkdir /usr/lib/jvm

$ sudo cp jdk-6u45-linux-x64.bin /usr/lib/jvm/

$ sudo chmod +x jdk-6u45-linux-x64.bin

$ sudo ./jdk-6u45-linux-x64.bin

# set environment

$ sudo mv jdk1.6.0_45/ jdk6

$ export JAVA_HOME=/usr/lib/jvm/jdk6

$ export JRE_HOME=${JAVA_HOME}/jre

$ export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib

$ export PATH=${JAVA_HOME}/bin:$PATH

# enable environment

source ~/.bashrc

# set JDK as default

$ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk6/bin/java 300

$ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk6/bin/javac 300

$ sudo update-alternatives --config java

# check java version

$ java -version

4. download android (and kernel if necessary)

# get repo

$ mkdir ~/bin

$ PATH=~/bin:$PATH

$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo

$ chmod a+x ~/bin/repo

# get android 4.2.2 r1 branch (example)

$ mkdir jbean

$ cd jbean

$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.2.2_r1

$ repo sync

# get android common kernel (example)

$ cd

$ mkdir kernel

$ cd kernel

$ git clone https://android.googlesource.com/kernel/common.git

$ cd common/.git/

$ git branch -a
