 <ul>
   <li><strong>Analytics</strong> - The Enhanced Ecommerce API allows your app
 to send product related information and actions to Google Analytics. Use this
 API to measure impressions of products seen by users, checkout steps, and
 products purchased. This information can be analyzed for the effectiveness of
 marketing and merchandising efforts, including the impact of internal
 promotions, coupons, and affiliate marketing programs.

 for developers to notify Google about deep links in their native apps and
 allows the Google Search App, version 3.6 and above, to drive re-engagement
 through Google Search
 <a href="https://support.google.com/websearch/answer/106230"

   <li><strong>Play Games</strong> - This release introduces the Quests and
 Saved Games services. The Quests service gives you the ability to issue
 time-bound in-game challenges based on Events data sent from your game, without
 republishing your game (for example:  Your game sends an event each time a
 “gem” is found by a player, and you create a quest to “Find 20 gems”). Players
 can complete a quest to earn rewards. Saved Games offers improved functionality
 for saving game state information and visually displaying player game progression.

 <h2>How It Works</h2>

 <h4 id="client-lib">The Google Play services client library</h4>
 <p>
     The client library contains the interfaces to the individual Google
     services and allows you to obtain authorization from users to gain access
     to these services with their credentials. It also contains APIs that allow
     you to resolve any issues at  runtime, such as a missing, disabled, or out-of-date
     Google Play services APK. The client library has a light footprint if you use
     <a href="/tools/help/proguard.html">ProGuard</a> as part of your build process, so it won't have
     an adverse impact on your app's file size.
 </p>
 <p>
     If you want to access added features or products, you can upgrade to a new version of the
     client library as they are released. However, upgrading is not
     necessary if you don't care about new features or bug fixes.
     We anticipate more Google services to be continuously added, so be on the lookout for
     these updates.
 </p>

 <div class="layout-content-row">
   <div class="layout-content-col span-6">
     <h4 id="apk">The Google Play services APK</h4>
     <p>
         The Google Play services APK contains the individual Google services and runs
         as a background service in the Android OS. You interact with the background service
         through the client library and the service carries out the actions on your behalf.
         An easy-to-use authorization flow is also
         provided to gain access to the each Google service, which provides consistency for both
         you and your users.
     </p>
     <p>
       The Google Play services APK is delivered through the Google Play Store, so
       updates to the services are not dependent on carrier or OEM system image updates. In general, devices
       running Android 2.3 (Gingerbread) or later and have the Google Play Store app installed receive updates within a
       few days. This allows you to use the newest APIs in Google Play services and reach most of the
       devices in the Android ecosystem (devices older than Android 2.3 or devices without the Google
       Play Store app are not supported).
     </p>

   </div>
 </div>

 <h4 id="benefits">The benefits for your app</h4>

 <p>Google Play services gives you the freedom to use the newest APIs for popular
 Google services without worrying about device support. Updates to Google Play
 services are distributed automatically by the Google Play Store and new versions
 of the client library are delivered through the Android SDK Manager. This makes it
 easy for you to focus on what's important: your users' experience.</p>

	<h2>How It Works</h2>

	<h4 id="client-lib">The Google Play services client library</h4>
	<p>
	The client library contains the interfaces to the individual Google
	services and allows you to obtain authorization from users to gain access
	to these services with their credentials. It also contains APIs that allow
	you to resolve any issues at runtime, such as a missing, disabled, or out-of-date
	Google Play services APK. The client library has a light footprint if you use
	<a href="/tools/help/proguard.html">ProGuard</a> as part of your build process, so it won't have
	an adverse impact on your app's file size.
	</p>
	<p>
	If you want to access added features or products, you can upgrade to a new version of the
	client library as they are released. However, upgrading is not
	necessary if you don't care about new features or bug fixes.
	We anticipate more Google services to be continuously added, so be on the lookout for
	these updates.
	</p>

	<div class="layout-content-col span-6">
	<h4 id="apk">The Google Play services APK</h4>
	<p>
	The Google Play services APK contains the individual Google services and runs
	as a background service in the Android OS. You interact with the background service
	through the client library and the service carries out the actions on your behalf.
	An easy-to-use authorization flow is also
	provided to gain access to the each Google service, which provides consistency for both
	you and your users.
	</p>
	<p>
	The Google Play services APK is delivered through the Google Play Store, so
	updates to the services are not dependent on carrier or OEM system image updates. In general, devices
	running Android 2.3 (Gingerbread) or later and have the Google Play Store app installed receive updates within a
	few days. This allows you to use the newest APIs in Google Play services and reach most of the
	devices in the Android ecosystem (devices older than Android 2.3 or devices without the Google
	Play Store app are not supported).

	<h4 id="benefits">The benefits for your app</h4>

	<p>Google Play services gives you the freedom to use the newest APIs for popular
	Google services without worrying about device support. Updates to Google Play
	services are distributed automatically by the Google Play Store and new versions
	of the client library are delivered through the Android SDK Manager. This makes it
	easy for you to focus on what's important: your users' experience.</p>
