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.
