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.
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 to checkout the code and an extra 150GB to build it. If you conduct multiple builds or 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.
The Android Open Source Project
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.
OS and JDK
If you are developing against the AOSP
master branch, use one
of these operating systems: Ubuntu 14.04 (Trusty) or Mac OS v10.10 (Yosemite)
or later with Xcode 4.5.2 and Command Line Tools.
For the Java Development Kit (JDK), note the
master branch of
Android in AOSP comes with a prebuilt version of OpenJDK; so no additional
installation is required. Older versions require a separate install.
- Python 2.6 -- 2.7 from python.org
- GNU Make 3.81 -- 3.82 from gnu.org
- Git 1.7 or newer from git-scm.com

Development Kit (NDK) and legacy kernels, GCC 4.9 included
in the AOSP master branch (under
prebuilts/) may also be used.
Packages for older versions
The sections below provide relevant operating systems and JDK packages for older versions of Android.
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.
- 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
Note: consider building on GNU/Linux, not another operating system. The Android build system normally uses ART, running on the build machine, to pre-compile system dex files. Since ART is able to run only on Linux, the build system skips this pre-compilation step on non-Linux operating systems, resulting in an Android build with reduced performance.
See Installing the JDK for the prebuilt path and installation instructions for older versions.
- Android 7.0 (Nougat) - Android 8.0 (O release): 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
Android 4.0.x (Ice Cream Sandwich) and earlier will need to revert from make 3.82 to avoid build errors.
