Getting started with AOSP

Hardware requirements

Minimal requirements needed for your workstation.

  1. 64-bit environment
  2. At least 100GB of disk space. If you conduct multiple builds you will need more space.
  3. At least 4GB of RAM

Software requirements

You can build Android on Linux or Mac. But I prefer Linux specifically Ubuntu LTS(Long Term Support), because AOSP master branch is developed and tested on Ubuntu LTS. So software requirements are,

  1. OS - Ubuntu 12.04/14.04
  2. Java Development Kit(JDK) - OpenJDK 7
  3. Python 2.7
  4. GNU Make 3.82
  5. Git 1.7 or newer

Setting up build environment

Installing JDK

Since we are using Linux, I will give instructions to install the OpenJDK. Install OpenJDK using below commands.


$ sudo apt-get update
$ sudo apt-get install openjdk-7-jdk

Update the default Java version by running


$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac


Install required packages


$ sudo apt-get -y install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib 
$ sudo apt-get -y install libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache libgl1-mesa-dev libxml2-utils 
$ sudo apt-get -y install xsltproc unzip mtd-utils u-boot-tools lzop liblzo2-2 liblzo2-dev zlib1g-dev liblz-dev uuid uuid-dev


Downloading the source

Installing Repo

Repo is a tool which is used to handle a number of Git repositories. Repo is developed for handling the Android Development.

To install Repo,

  1. Make a bin directory in your home directory
  2. 
    $ mkdir ~/bin
    $ PATH=~/bin:$PATH
    
  3. Download Repo tool and give needed permissions
  4. 
    $ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
    $ chmod a+x ~/bin/repo
    
  5. Initialize repo client
  6. 
    $ mkdir ~/working_directory
    $ cd ~/working_directory/
    $ mkdir my_android
    $ cd my_android/ 
    $ repo init -u https://android.googlesource.com/platform/manifest -b  android-6.0.1_r3
    $ repo sync
    

repo sync will take some time to execute, because it is downloading whole source of Android OS. It will be nearly 50GB - 60GB. So you can have a tea break. Once the repo sync is executed then you have the Android Source.
