Download and Build

System requirements

Listed below are the recommended requirements for downloading and building the SDK:

• CPU: x86_64 or better family processor
• Memory: 8GB or higher
• Disk: 10GB free hard disk space
• OS: Ubuntu 14.04 (tested) or higher
• Network: internet connection

Linux host setup

Ubuntu 14.04

HINT: later version should also work.

Install prerequisites

$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install git git-core u-boot-tools qemu qemu-user-static debootstrap lib32z1 lib32ncurses5 libc6:i386 libstdc++6:i386 gawk

• dpkg --add-architecture i386: support 32bit architecture
• apt-get update: retrieve new lists of packages
• git git-core: manage source code
• u-boot-tools: build kernel image
• qemu qemu-user-static: emulator for arm on host CPU
• debootstrap: for installing a Debian base system
• lib32z1 lib32ncurses5 libc6:i386 libstdc++6:i386: for running 32bit tools

Downloading

The SDK is available on github.

We use Repo manage Git repositories. Clone Repo from android Git repositories or other mirrors and install it.
Chinese developers can install Repo follow these steps:

$ git clone http://mirrors.ustc.edu.cn/aosp/git-repo.git ~/.bin/repo
$ echo "export PATH=~/.bin/repo:$PATH" >> ~/.bashrc
$ source ~/.bashrc
