   <em>Android growth in device activations</em></div>


 <h3>Global partnerships and large installed base</h3>

 <p>Building on the contributions of the open-source Linux community and more
 than 300 hardware, software, and carrier partners, Android has rapidly become
 the fastest-growing mobile OS.</p>

 <blockquote>Every day more than 1 million new Android devices are activated worldwide.</blockquote>

 <p>Android’s openness has made it a favorite for consumers and developers alike,
 driving strong growth in app consumption. Android users download more than
 1.5 billion apps and games from Google Play each month. </p>

 <p>With its partners, Android is continuously pushing the boundaries of hardware and software
 forward to bring new capabilities to users and developers. For developers,
 Android innovation lets you build powerful, differentiated applications
 that use the latest mobile technologies.</p>

 <!-- <h3>Rapid innovation</h3>

 <p>Android is continuously pushing the boundaries of hardware and software
 forward, to bring new capabilities to users and developers. For developers, the
 rapid evolution of Android technology lets you stay in front with powerful,
 differentiated applications.</p>

 <p>Android gives you access to the latest technologies and innovations across a
 multitude of device form-factors, chipset architectures, and price points. From
 multicore processing and high-performance graphics to state-of-the-art sensors,
 vibrant touchscreens, and emerging mobile technologies such as Near Field
 Communication (NFC), Wi-Fi Direct, and face tracking.</p> -->

 <h3>Powerful development framework</h3>

 <blockquote>Easily optimize a single binary for phones, tablets, and other devices.</blockquote>

 <p>Android gives you everything you need to build best-in-class app experiences.
 It gives you a single application model that lets you deploy
 your apps broadly to hundreds of millions of users across a wide range of
 devices&mdash;from phones to tablets and beyond.</p>

 <p>Android also gives you tools for creating apps that look great and take
 advantage of the hardware capabilities available on each device. It
 automatically adapts your UI to look its best on each device, while giving you
 as much control as you want over your UI on different device
 types. </p>

 <p>For example, you can create a single app binary that's optimized for
 both phone and tablet form factors. You declare your UI in lightweight sets of XML
 resources, one set for parts of the UI that are common to all form factors and
 other sets for optimzations specific to phones or tablets.
 At runtime, Android applies the correct resource sets based on its screen size,
 density, locale,
 and so on.</p>


 <p>To help you develop efficiently, the <a href="{@docRoot}tools/index.html">Android
     Developer Tools</a>
 offer a full Java IDE with advanced features for developing, debugging, and
 packaging Android apps. Using the IDE, you can develop on any available Android
 device or create virtual devices that emulate any hardware configuration.</p>

 <blockquote>1.5 billion downloads a month and growing. Get your apps in front
 of millions of users at Google's scale.</blockquote>

 <h3>Open marketplace for distributing your apps</h3>

 <p>Google Play is the premier marketplace for selling and distributing Android apps.
 When you publish an app on Google Play, you reach the huge installed base of
 Android.</p>

 <div style="float:left;margin-right:24px;margin-top:12px;">
 <img src="{@docRoot}images/gp-device.png">
 </div>

 <p>As an open marketplace, Google Play puts you in control of how you sell your
 products. You can publish whenever you want, as often as you want, and to the
 customers you want. You can distribute broadly to all markets and
 devices or focus on specific segments, devices, or ranges of hardware
 capabilities.</p>

 <p>You can monetize in the way that works best for your business&mdash;priced or
 free, with in-app products or subscriptions&mdash;for highest engagement and
 revenues. You also have complete control of the pricing for your apps
 and in-app products and can set or change prices in any supported currency at
 any time.<p>

 <p>Beyond growing your customer base, Google Play helps you build visibility and
 engagement across your apps and brand. As your apps rise in popularity, Google
 Play gives them higher placement in weekly "top" charts and rankings, and for
 the best apps promotional slots in curated collections.
 </p>

 <p>Preinstalled on hundreds of millions of Android devices around the world,
 Google Play can be a growth engine for your business.</p>
