Before you download and build the Android source, ensure your system meets the following requirements. Then see Establishing a Build Environment for installation instructions by operating system.

Hardware requirements

Your development workstation should meet or exceed these hardware requirements:

A 64-bit environment is required for Gingerbread (2.3.x) and newer versions, including the master branch. You can compile older versions on 32-bit systems.
At least 100GB of free disk space for a checkout, 150GB for a single build, and 200GB or more for multiple builds. If you employ ccache, you will need even more space.
If you are running Linux in a virtual machine, you need at least 16GB of RAM/swap.

Software requirements

The Android Open Source Project (AOSP) master branch is traditionally developed and tested on Ubuntu Long Term Support (LTS) releases, but other distributions may be used. See the list below for recommended versions.

You workstation must have the software listed below. See Establishing a Build Environment for additional required packages and the commands to install them.

Operating system

Android is typically built with a GNU/Linux or Mac OS operating system. It is also possible to build Android in a virtual machine on unsupported systems such as Windows.

GNU/Linux

Android 6.0 (Marshmallow) - AOSP master: Ubuntu 14.04 (Trusty)
Android 2.3.x (Gingerbread) - Android 5.x (Lollipop): Ubuntu 12.04 (Precise)
Android 1.5 (Cupcake) - Android 2.2.x (Froyo): Ubuntu 10.04 (Lucid)

Mac OS (Intel/x86)

Android 6.0 (Marshmallow) - AOSP master: Mac OS v10.10 (Yosemite) or later with Xcode 4.5.2 and Command Line Tools
Android 5.x (Lollipop): Mac OS v10.8 (Mountain Lion) with Xcode 4.5.2 and Command Line Tools
Android 4.1.x-4.3.x (Jelly Bean) - Android 4.4.x (KitKat): Mac OS v10.6 (Snow Leopard) or Mac OS X v10.7 (Lion) and Xcode 4.2 (Apple's Developer Tools)
Android 1.5 (Cupcake) - Android 4.0.x (Ice Cream Sandwich): Mac OS v10.5 (Leopard) or Mac OS X v10.6 (Snow Leopard) and the Mac OS X v10.5 SDK

Java Development Kit (JDK)

Please note, since there are no available supported OpenJDK 8 packages for Ubuntu 14.04, the Ubuntu 15.04 packages must be installed manually. See JDK for Ubuntu LTS 14.04 for precise instructions.

The master branch of Android in AOSP: Ubuntu - OpenJDK 8, Mac OS - jdk 8u45 or newer
Android 5.x (Lollipop) - Android 6.0 (Marshmallow): Ubuntu - OpenJDK 7, Mac OS - jdk-7u71-macosx-x64.dmg
Android 2.3.x (Gingerbread) - Android 4.4.x (KitKat): Ubuntu - Java JDK 6, Mac OS - Java JDK 6
Android 1.5 (Cupcake) - Android 2.2.x (Froyo): Ubuntu - Java JDK 5

Key packages

Python 2.6 -- 2.7 from python.org
GNU Make 3.81 -- 3.82 from gnu.org; Android 3.2.x (Honeycomb) and earlier will need to revert from make 3.82to avoid build errors
Git 1.7 or newer from git-scm.com

Device binaries

Download previews, factory images, drivers, over-the-air (OTA) updates, and other blobs below. See Obtaining proprietary binaries for additional details.

Preview binaries (blobs) - for AOSP master branch development
Factory images - for the supported devices running tagged AOSP release branches
Binary hardware support files - for devices running tagged AOSP release branches
OTA images - for manually updating Nexus devices over the air
