推荐订阅源

1.安装 ubuntu 14.03 

       尽管android推荐 ubuntu 15, 安全起见，还是装LTS的14.04，步骤跳过

2. JDK:

Marshmallow 需要 JDK8 ,添个源，顺手配下java

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update 
sudo update-alternatives --config java
sudo update-alternatives --config javac

3.装下依赖项

sudo apt-get install git-core gnupg flex bison gperf build-essential \
  zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
  lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
  libgl1-mesa-dev libxml2-utils xsltproc unzip

4. adb USB 

 wget -S -O - http://source.android.com/source/51-android.rules | sed "s/<username>/$USER/" | sudo tee >/dev/null /etc/udev/rules.d/51-android.rules; sudo udevadm control --reload-rules

5.设置编译输出目录

export OUT_DIR_COMMON_BASE=<path-to-your-out-directory>

6.装个REPO工具$ mkdir ~/bin

墙外

mkdir ~/bin
PATH=~/bin:$PATH

curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

chmod a+x ~/bin/repo

墙内
cd ~
git clone git://aosp.tuna.tsinghua.edu.cn/android/git-repo.gitPATH=~/git-repo:$PATH

7.建个工作目录

mkdir ~/marshmallow
cd ~/marshmallow

墙内

指定Head版本repo init -u git://aosp.tuna.tsinghua.edu.cn/aosp/platform/manifest
指定分支

repo init -u git://aosp.tuna.tsinghua.edu.cn/aosp/platform/manifest -b android-6.0.1_r16

墙外

repo init -u https://android.googlesource.com/platform/manifest
或者

repo init -u https://android.googlesource.com/platform/manifest -b android-6.0.1_r16
