19<p>The Android build is routinely tested in-house on recent versions of
20Ubuntu LTS (12.04), 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>

28  <li>A Linux or Mac 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 30GB or more of disk space in order to
32  build the Android tree.
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>30GB of free disk space to complete a single build and
40  up to 100GB or more for a full set of builds.  The source download is approximately 8.5GB in size.</p>
