<p>At a high level, Android development happens around families of
releases, which use code names ordered alphabetically after tasty
treats.</p>

<h2 id="platform-code-names-versions-api-levels-and-ndk-releases">Platform Codenames, Versions, API Levels, and NDK Releases</h2>
<p>The code names match the following version numbers, along with
API levels and NDK releases provided for convenience:</p>
<table>
<thead>

<p>Starting with Cupcake, individual builds are identified with a short
build code, e.g. FRF85B.</p>
<p>The first letter is the code name of the release family, e.g. F is
Froyo.</p>
<p>The second letter is a branch code that allows Google to identify
the exact code branch that the build was made from, and R is by
convention the primary release branch.</p>
<p>The next letter and two digits are a date code. The letter counts
quarters, with A being Q1 2009. Therefore, F is Q2 2010. The two
digits count days within the quarter, so F85 is June 24 2010.</p>
<p>Finally, the last letter identifies individual versions related to
the same date code, sequentially starting with A; A is actually
implicit and usually omitted for brevity.</p>
<p>The date code is not guaranteed to be the exact date at which a build
was made, and it is common that minor variations added to an existing
build re-use the same date code as that existing build.</p>

<h2 id="source-code-tags-and-builds">Source Code Tags and Builds</h2>

following table:</p>

<p>The branches froyo, gingerbread, ics-mr0, ics-mr1, jb-dev,
jb-mr1-dev, jb-mr1.1-dev, jb-mr2-dev
represent development
branches that do not exactly match configurations that were tested
by Google. They might contain a variety of changes in addition to
the official tagged releases, and those haven't been as thoroughly
tested.</p>

<p>There is no manifest that contains exactly those. However, there
are manifests that allow building those components. The following
commands work for 3.0_r1.1, and using other versions can be done by
switching the git checkout paramater, and if necessary the -m parameter in
repo init. The git checkout command outputs an error for the non-GPL
projects, where it can't find the tag in question.</p>
<pre><code>$ repo init -b master -m base-for-3.0-gpl.xml
$ repo sync
$ repo forall -c git checkout android-3.0_r1.1
