19<p>The Android build is routinely tested in-house on recent versions of
20Ubuntu LTS (14.04), but most distributions should have the required
21build tools available. We welcome reports of successes or failures on other
22distributions.</p>
23
24<p>Before you download and build the Android source, ensure your system meets the following requirements:</p>
25
26<ul>
27
28  <li>A Linux or Mac OS system. It is also possible
29  to build Android in a virtual machine on unsupported systems such as Windows.
30  If you are running Linux in a virtual machine, you need at
31  least 16GB of RAM/swap and 50GB or more of disk space in order to
32  build the Android tree. See disk size requirements below.
33  </li>
34
35  <li>A 64-bit environment is required for Gingerbread (2.3.x) and newer versions, including the master
36  branch. You can compile older versions on 32-bit systems.
37  </li>
38
39  <li>At least 50GB of free disk space for a checkout, 100GB for a single
40  build, and 150GB or more for multiple builds. If you employ ccache, you will
41  need even more space.</p>
42  </li>
43
44  <li>
45  Python 2.6 -- 2.7, which you can download from <a href="http://www.python.org/download/">python.org</a>.</p>
46  </li>
47
48  <li>
49  GNU Make 3.81 -- 3.82, which you can download from <a href="http://ftp.gnu.org/gnu/make/">gnu.org</a>,</p>
50  </li>
51
52  <li>
53  JDK 7 to build the master branch of Android in the <a
54  href="https://android.googlesource.com/">Android Open Source Project
55  (AOSP)</a>; JDK 6 to build Gingerbread through KitKat; JDK 5 for Cupcake through
56  Froyo. See <a href="initializing.html">Initializing a Build Environment</a>
57  for installation instructions by operating system.</p>
58  </li>
59
60  <li>
61  Git 1.7 or newer. You can find it at <a href="http://git-scm.com/download">git-scm.com</a>.</p>
