+<p>Android is an open-source software stack created for mobile phones and
+other devices. The Android Open Source Project (AOSP) is tasked with the
+maintenance and further development of Android. Many device manufacturers have
+brought to market devices running Android, and they are readibly available
+around the world.</p>
+<p>Our primary purpose is to build an excellent software platform for everyday
+users. A number of companies have committed many engineers to achieve this
+goal, and the result is a full production quality consumer product whose
+source is open for customization and porting.</p>

+page.title=Philosophy and Goals
+doc.type=about
+@jd:body
+<div id="mainBodyFixed">
+<p>Android is an open-source software stack for mobile phones and similar
+devices. The Android Open Source Project is tasked with maintaining current
+and developing new versions of the Android software. We believe that users
+deserve to have the source code to the software they run on their devices,
+that developers deserve an open, level playing field for their apps, and that
+OEMs and carriers deserve the freedom to differentiate and innovate. That's
+why we created Android, and made the source code open.</p>
+<h2>Origin and Goal</h2>
+<p>Android was originated by a group of companies known as the Open Handset
+Alliance, led by Google. Today, many companies -- both original members of the
+OHA and others -- have invested heavily in Android, typically in the form of
+allocating significant engineering resources to improve Android and bring
+Android devices to Market.</p>
+<p>We created Android in response to our own experiences launching mobile
+apps. We wanted to make sure that there would always be an open platform
+available for carriers, OEMs, and developers to use to make their innovative
+ideas a reality. We wanted to make sure that there was no central point of
+failure, where one industry player could restrict or control the innovations
+of any other. The solution we chose was an open and open-source platform.</p>
+<p>But the ultimate goal, of course, is to improve the mobile experience for
+real users by facilitating innovation. Accordingly, the primary goal of the
+AOSP is to make sure Android is a success as an end user product.</p>
+<h2>Governance Philosophy</h2>
+<p>The companies that have invested in Android have done so on its merits,
+because we collectively believe that an open platform is necessary. In some
+ways, Android is the purest form of an open-source (as opposed to free
+software) effort: a group of organizations with shared needs has pooled
+resources to collaborate on a single implementation of a shared product. That
+is, the Android philosophy is pragmatic, first and foremost. The objective is
+a shared product that each contributor can tailor and customize.</p>
+<p>Uncontrolled customization can, of course, lead to incompatibile
+implementations. To prevent this, the AOSP also maintains the Android
+Compatibility Program, which spells out what it means to be "Android
+compatible", and what is required of device builders to achieve that status.
+Anyone can (and will!) use the Android source code for any purpose, and we
+welcome all such uses. However, in order to take part in the shared
+ecosystem that we are building around Android, device builders can take
+advantage of the Compatibility Program.</p>
+<p>Though Android consists of multiple sub-projects, this is strictly a
+project-management technique. We view and manage Android as a single,
+holistic software product, not a "distribution", specification, or collection
+of replaceable parts. Conceptually, our notion is that device builders port
+Android to a device; they don't implement a specification or curate a
+distribution.</p>
+<h2>How We Work</h2>
+<p>We know that quality does not come without hard work. The
+members of the Android Open Source Project have contributed full-time
+engineers, product managers, UI designers, Quality Assurance, and all the
+other roles required to launch modern devices in the modern marketplace.
+We integrate the open source administration and maintenance into the larger
+product development cycle.</p>
+<p>In a nutshell:</p>
+<ul>
+<li>At any given moment, there is a current latest release of the Android
+platform. This typically takes the form of a branch in the tree.</li>
+<li>AOSP members, device builders, and contributors work with the current
+latest release, fixing bugs, launching new devices, experimenting with new
+features, and so on.</li>
+<li>In parallel, the AOSP members work internally on the next version of the
+Android platform and framework, working according to the product's needs and
+goals. Some of the work from the current latest tree will promoted into these
+releases.</li>
+<li>When the "n+1"th version is determined to be nearing completion, it will
+be published to the public source tree, and become the new latest
+release.</li>
+<li>Since Android is open source, nothing prevents device implementers from
+shipping devices on older (obsolete) Android builds. However, active work will
+be focused on the current platform release.</li>
+</ul>
+<p>To meet our goals, Android needs to achieve widespread, compatible
+adoption. We believe that the best way to accomplish that is to make sure that
+we ship high-quality, flagship devices with an intense product and end-user
+focus. The "next release" of Android is driven by the product needs for the next
+generation of mobile devices; the resulting excellent product is then released
+to open source and becomes the new current version of the platform.</p>
