| <p> |
| These requirements apply to older versions of Android. For the Android Open Source Project (AOSP) |
| <code>master</code> branch, see the standard <a href="requirements">Requirements</a> and |
| <a href="initializing">Establishing a Build Environment</a>. 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. |
| </p> |
| |
| <h2 id=operating-systems>Operating systems</h2> |
| <p> |
| Android is typically built with a GNU/Linux or Mac OS operating system. It is |
| also possible to build Android in a virtual machine on unsupported systems |
| such as Windows. |
| </p> |
| |
| <p>We recommend building on GNU/Linux instead of another operating system. The |
| Android build system normally uses ART, running on the build machine, to |
| pre-compile system dex files. Since ART is able to run only on Linux, the |
| build system skips this pre-compilation step on non-Linux operating systems, |
| resulting in an Android build with reduced performance. |
| </p> |

| <h2 id=make>Make</h2> |
| <p> |
| To avoid build errors, Android 4.0.x (Ice Cream Sandwich) and earlier must |
| <a href="initializing.html#reverting-from-make-382">revert from make 3.82</a>. |
| </p> |
| |
| <h3 id="xcode-other-packages">Xcode and other packages</h3> |
| <p> |
| For older versions of Mac OS (10.8 or earlier), you must install Xcode from |
| the <a href="http://developer.apple.com/" class="external">Apple developer |
| site</a>. If you are not already registered as an Apple developer, you must |
| create an Apple ID to download. |
| </p> |
| <p> |
| If using Mac OS X v10.4, also install bison: |
| <pre class="devsite-terminal devsite-click-to-copy"> |
| POSIXLY_CORRECT=1 sudo port install bison</pre> |
| </p> |
| |
| <p> |
| For MacPorts, issue: |
| <pre class="devsite-terminal devsite-click-to-copy"> |
| POSIXLY_CORRECT=1 sudo port install gmake libsdl git gnupg</pre> |
| </p> |
| |
| <p> |

| |
| <h3 id="reverting-from-make-382">Reverting from make 3.82</h3> |
| <p> |
| In Android 4.0.x (Ice Cream Sandwich) and earlier, a bug exists in gmake 3.82 |
| that prevents Android from building. You can install version 3.81 using |
| MacPorts with these steps: |
| </p> |
| <ol> |
| <li>Edit <code>/opt/local/etc/macports/sources.conf</code> and add a line that |
| says: |
| <pre class="devsite-click-to-copy"> |
| file:///Users/Shared/dports</pre> |
| above the rsync line. Then create this directory: |
| <pre class="devsite-terminal devsite-click-to-copy"> |
| mkdir /Users/Shared/dports</pre> |
| </li> |
| <li>In the new <code>dports</code> directory, run: |
| <pre class="devsite-terminal devsite-click-to-copy"> |
| svn co --revision 50980 http://svn.macports.org/repository/macports/trunk/dports/devel/gmake/ devel/gmake/</pre> |
| </li> |
| <li>Create a port index for your new local repository: |
| <pre class="devsite-terminal devsite-click-to-copy"> |
| portindex /Users/Shared/dports</pre> |
| </li> |
| <li>Install the old version of gmake with: |
| <pre class="devsite-terminal devsite-click-to-copy"> |
| sudo port install gmake @3.81</pre> |
| </li> |

| The <code>master</code> branch of Android in the |

| <code>prebuilts/jdk/</code> so no additional installation is required. |
| </p> |
| <p> |
| Older versions of Android require a separate installation of the JDK. On |
| Ubuntu, use |
| <a href="http://openjdk.java.net/install/" class="external">OpenJDK</a>. See |
| <a href="requirements.html#jdk">JDK Requirements</a> for precise versions and |
| the sections below for instructions. |

| <li>Optionally, confirm the checksums of the downloaded files against the |
