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.</p>

23<p>Before you download and build the Android source, ensure your system meets
24the 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 100GB 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 100GB of free disk space for a checkout, 150GB for a single
40 build, and 200GB or more for multiple builds. If you employ ccache, you will
41 need even more space.</p>
42 </li>
43
44 <li>

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>
