 <p>
   Before you download and build the Android source, ensure your system meets
   the following requirements then see <a href="initializing.html">Establishing
   a Build Environment</a> for installation instructions by operating system.
 </p>

 <h2 id=hardware-requirements>Hardware requirements</h2>
 <p>
   Your development workstation should meet or exceed these hardware
   requirements:
 </p>
 <ul>
   <li>A 64-bit environment is required for Android 2.3.x (Gingerbread) and
     higher versions, including the master branch. You can compile older versions
     on 32-bit systems.
   </li>
   <li>At least 250GB of free disk space to checkout the code and an extra 150GB
     to build it. If you conduct multiple builds, you will need even more space.
     <aside class="note"><strong>Note:</strong> If you are checking out a mirror
       you will need more space as full Android Open Source Project (AOSP) mirrors
       contain all Git repositories that have ever been used.</aside>
   </li>
   <li>If you are running Linux in a virtual machine, you need at
     least 16GB of RAM/swap.
   </li>
 </ul>

 <h2 id=software-requirements>Software requirements</h2>
 <p>
   The <a href="https://android.googlesource.com/" class="external">Android Open
   Source Project (AOSP)</a> <code>master</code> 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.
 </p>
 <p>
   Your workstation must have the software listed below. See
   <a href="initializing.html">Establishing a Build Environment</a> for
   additional required packages and the commands to install them.
 </p>
 <p>
   These requirements apply to the AOSP master branch. For Android
   versions 8.0 (Oreo or O) through 5.0 (Lollipop or L), consider using the included
   <a href="https://android.googlesource.com/platform/build/+/master/tools/docker">Dockerfile</a>
   to ease installation of all required packages. For the manual method, see
   <a href="older-versions">Supporting Older Versions</a>.
 </p>

 <h3 id=os>OS</h3>
 <p>
   If you are developing against the AOSP <code>master</code> branch, use one of these operating
   systems: Ubuntu 14.04 (Trusty) or the latest versions of Mac OS and Xcode with Command Line Tools
   installed.
 </p>

 <h3 id=jdk>JDK</h3>
 <p>
   The <code>master</code> branch of Android in AOSP comes with a prebuilt version of OpenJDK, so no
   additional installation is required.
 </p>
 <p>Older versions of Android require a separate installation of the JDK. On Ubuntu, use OpenJDK. See
   <a href="older-versions">Supporting Older Versions</a> for precise versions and instructions.

 <h3 id=packages>Key packages</h3>
 <p>
   The AOSP master branch comes with a prebuilt version of Make, so no additional installation is
   required.
     </p>
 <ul>
   <li><a href="http://ftp.gnu.org/gnu/make/" class="external">GNU Make 3.81 to 3.82</a> for older
     versions</li>
   <li><a href="http://www.python.org/download/" class="external">Python 2.7</a></li>
   <li><a href="http://git-scm.com/download" class="external">Git 1.7 or higher</a></li>
 </ul>

 <h3 id=binaries>Device binaries</h3>
 <p>
   Download previews, factory images, drivers, over-the-air (OTA) updates, and
   other blobs below. For details, see
   <a href="building.html#obtaining-proprietary-binaries">Obtaining proprietary
   binaries</a>.
 </p>
 <ul>
   <li><a href="https://developers.google.com/android/blobs-preview" class="external">Preview
     binaries (blobs)</a>. For AOSP <code>master</code> branch development.
   </li>
   <li><a href="https://developers.google.com/android/images" class="external">Factory
     images</a>. For supported devices running tagged AOSP release branches.
   </li>
   <li><a href="https://developers.google.com/android/drivers" class="external">Binary
     hardware support files</a>. For devices running tagged AOSP release
     branches.
   </li>
 </ul>

 <h3 id=toolchain>Build toolchain</h3>
 <p>
   Android 8.0 and higher support only
   <a href="https://developer.android.com/ndk/guides/standalone_toolchain.html#working_with_clang" class="external">Clang/LLVM</a>
   for building the Android platform. Join the
   <a href="https://groups.google.com/forum/#!forum/android-llvm" class="external">android-llvm</a>
   group to pose questions and get help. Report NDK/compiler issues at the
   <a href="https://github.com/android-ndk/ndk" class="external">NDK GitHub</a>.
 </p>
 <p>
   For the
   <a href="https://developer.android.com/ndk/guides/index.html" class="external">Native
   Development Kit (NDK)</a> and legacy kernels, GCC 4.9 included in the AOSP
   master branch (under <code>prebuilts/</code>) may also be used.
