<ul>
  <li><strong>Maps</strong> - This release makes the Google Maps Android API v2 available on
<a href="https://developers.google.com/maps/documentation/android/wear" class="external-link">
Android Wear</a>, so you can now create map-based apps that run directly on wearable devices. In
addition, the Maps API now offers a new
<a href="{@docRoot}reference/com/google/android/gms/maps/StreetViewPanorama.OnStreetViewPanoramaLongClickListener.html">
{@code OnStreetViewPanoramaLongClickListener}</a> interface, similar to the existing
<a href="{@docRoot}reference/com/google/android/gms/maps/GoogleMap.OnMapLongClickListener.html">
{@code OnMapLongClickListener}</a> interface. These listeners are particularly helpful
for wearable devices, so you can let users exit from the app by long-clicking on a map or panorama.
On a wearable device, the swipe gesture is used to pan the map instead of exiting the app.

  <li>
    <strong>Wear</strong> - In addition to Maps support, this release provides you with the ability
to advertise and discover the capabilities of devices that are connected in a Wear network, through
the new <a href="{@docRoot}reference/com/google/android/gms/wearable/CapabilityApi.html">
{@code CapabilityApi}</a> class. The new
<a href="{@docRoot}reference/com/google/android/gms/wearable/ChannelApi.html">{@code ChannelApi}</a>
class lets you send and receive data bi-directionally from your wearable app on a device to another
wearable node. Use the Channel API to send large files for offline access or to stream real-time
binary data.

  <li>
    <strong>Location</strong> - This release adds a maximum wait time for location updates. By
calling the new
<a href="{@docRoot}reference/com/google/android/gms/location/LocationRequest.html#setMaxWaitTime(long)">
{@code setMaxWaitTime()}</a> method and passing in a value at least double the value requested with
the
<a href="{@docRoot}reference/com/google/android/gms/location/LocationRequest.html#setInterval(long)">
{@code setInterval()}</a> method, the system can batch location updates together, reducing battery
usage and, on some devices, improving location accuracy. In addition, you can use the new
<a href="{@docRoot}reference/com/google/android/gms/location/LocationCallback.html">
{@code LocationCallback}</a> class to be notified when the device location has changed or can no
longer be determined.
  </li>
  <li>
    <strong>Places</strong> - This release adds a
<a href="{@docRoot}reference/com/google/android/gms/location/places/PlaceBuffer.html#getAttributions()">

class="external-link">blog post</a>.</p>
<ul>
  <li><strong>Places</strong> - Using the Google Places API for Android, you can build
    location-aware apps that respond contextually to the local businesses and other places near
    the device. Use the built-in place picker UI widget and API methods to find the device’s
    current place, autocomplete users’ queries, and more.

  <li><strong>Location settings</strong> - While the
    <a href="{@docRoot}reference/com/google/android/gms/location/FusedLocationProviderApi.html">
      {@code FusedLocationProviderApi}</a>
    combines multiple sensors to give you the optimal location, the accuracy of the location your
    app receives still depends greatly on the settings enabled on the device (GPS, wifi, airplane
    mode, and others). Using the new
    <a href="{@docRoot}reference/com/google/android/gms/location/SettingsApi.html">
    {@code SettingsApi}</a>
    class, you can bring up a Location Settings dialog which displays a one-touch control for users
    to change their settings without leaving your app.
  </li>
  <li><strong>Fit</strong> - The Google Fit API is now more efficient with modular calls to specific
    functionality within the API. You can now also access distance and granular sleep data.

  <li><strong>Google Mobile Ads</strong> - This release introduces the
    <a href="{@docRoot}reference/com/google/android/gms/ads/doubleclick/PublisherAdRequest.Builder.html#addCustomTargeting(java.lang.String,%20java.lang.String)">
      {@code addCustomTargeting()}</a>

  </li>
  <li><strong>Play Game services</strong> - The Nearby Connections API allows users to connect to
      each other and exchange messages over a local network. This API supports local multiplayer
      and second screen gaming.
    <ul>

  <li><strong>Google API client</strong> - This release introduces the
  <a href="{@docRoot}reference/com/google/android/gms/common/api/GoogleApiClient.Builder.html#requestServerAuthCode(java.lang.String,%20com.google.android.gms.common.api.GoogleApiClient.ServerAuthCodeCallbacks)">{@code GoogleApiClient.Builder.requestServerAuthCode()}</a> method. This API makes it significantly easier
    to enable servers to be able to make Google API calls on behalf of users. This method reduces
    the lines of boilerplate code that you previously had to implement.
    <ul>
      <li><a href="https://developers.google.com/identity/sign-in/android/sign-in.html#enable_server-side_api_access_for_your_app"
        class="external-link">Server-side API access developer guide</a></li>
    </ul>
  </li>
  <li>
    <strong>Drive</strong> - This release adds
    <a href="{@docRoot}reference/com/google/android/gms/drive/DriveResource.html#trash(com.google.android.gms.common.api.GoogleApiClient))">
      {@code trash()}</a> and
    <a href="{@docRoot}reference/com/google/android/gms/drive/DriveResource.html#untrash(com.google.android.gms.common.api.GoogleApiClient)">
      {@code untrash()}</a> methods to the
      <a href="{@docRoot}reference/com/google/android/gms/drive/DriveResource.html">
        {@code DriveResource}</a>
      class. These methods enable you to move user-visible files and folders to the trash or
      restore them from the trash. Trashing a folder recursively trashes its children. The
      <a href="{@docRoot}reference/com/google/android/gms/drive/Metadata.html#isExplicitlyTrashed()">
      {@code isExplicitlyTrashed()}</a> method indicates whether a resource was trashed directly,
      or as the result of a trashed parent.

          class="external-link">Trashing and untrashing developer guide</a></li>
      </ul>
  </li>
  <li><strong>SafetyNet API</strong> - The API lets you check if your app is running on a device
    that matches a device model that has passed Android compatibility testing. The API evaluates
    both software and hardware characteristics of a device to determine whether it matches a
    known-good configuration that has been previously determined to be compatible. You can use the
    SafetyNet API in conjunction with other tools to determine whether the device appears capable
    of handling specific features in your app.

<ul>
  <li><strong>Maps</strong> - The new <em>lite mode</em> lets your app display a
bitmap image of a map, while still being able to control markers and shapes
client-side. This is particularly useful when you're showing a number of small
maps. You can enable or disable a new map toolbar that lets users open
<a href="https://www.google.com/maps" class="external-link">Google Maps</a> and
get directions and turn by turn navigation to the selected marker. The
{@code getMap()} method in
<a href="{@docRoot}reference/com/google/android/gms/maps/MapView.html">{@code MapView}</a>
and
<a href="{@docRoot}reference/com/google/android/gms/maps/MapFragment.html">{@code MapFragment}</a>
is now deprecated in favor of the new {@code getMapAsync()} method. Similarly,
the new {@code getStreetViewPanoramaAsync()} method in
<a href="{@docRoot}reference/com/google/android/gms/maps/StreetViewPanoramaView.html">{@code StreetViewPanoramaView}</a> and
<a href="{@docRoot}reference/com/google/android/gms/maps/StreetViewPanoramaFragment.html">{@code StreetViewPanoramaFragment}</a>
enables you to get a ready-to-use Street View panorama.

        class="external-link">Map toolbar developer guide</a></li>
    </ul>
  </li>
  <li><strong>Drive</strong> - This release introduces support for inserting or
  updating custom properties. You can now create empty files (for example, a user
  preference file that is empty until the user defines some application property).

        class="external-link">Creating empty files developer guide</a></li>
    </ul>
  </li>
  <li><strong>Fit</strong> - The Fit API now supports activity segments
    (<a href="{@docRoot}reference/com/google/android/gms/fitness/data/DataType.html#TYPE_ACTIVITY_SEGMENT">{@code DataType.TYPE_ACTIVITY_SEGMENT}</a>), which
    enable you to represent pauses within a workout session and to annotate time
    intervals inside a session with different fitness activities.
  </li>
  <li><strong>Wallet</strong> - You can now enable donations from your Android
    app in the same way you enable purchases. To do so, create a
    <a href="{@docRoot}reference/com/google/android/gms/wallet/fragment/WalletFragment.html">{@code WalletFragment}</a> and specify the
    <a href="{@docRoot}reference/com/google/android/gms/wallet/fragment/WalletFragmentMode.html#BUY_BUTTON">{@code BUY_BUTTON}</a>
    mode, then set the button text to
    <a href="{@docRoot}reference/com/google/android/gms/wallet/fragment/BuyButtonText.html#DONATE_WITH_GOOGLE">{@code DONATE_WITH_GOOGLE}</a>.
    <p class="note"><strong>Note:</strong> Use of the <em>Donate with Google</em>
    button is limited to 501(c)(3) organizations. For more information, see the
    <a href="https://support.google.com/wallet/business/answer/75724?hl=en&rd=1" class="external-link">Content policies</a>.</p>

  </li>
  <li><strong>Granular dependency management</strong> - If the number of
    references in your app exceeds the
    <a href="{@docRoot}tools/building/multidex.html">65K method reference limit</a>,
    your app may fail to compile. To avoid this problem, you can include just
    the specific Google Play services APIs your app uses, instead of all of them,
    when compiling your app. For more details, see the Android Studio setup
    instructions in
    <a href="{@docRoot}google/play-services/setup.html">Setting Up Google Play Services</a>.
  </li>
  <li><strong>Deprecated clients</strong> - The {@code ActivityRecognitionClient},
    {@code LocationClient}, and {@code PlusClient} classes are deprecated. If
    you used those APIs in your app and want to call Google Play services 6.5
    or higher APIs, you must switch to the new programming model that utilizes
    <a href="{@docRoot}reference/com/google/android/gms/common/api/GoogleApiClient.html">{@code GoogleApiClient}</a>. For more information about using <a href="{@docRoot}reference/com/google/android/gms/common/api/GoogleApiClient.html">{@code GoogleApiClient}</a>, see <a href="{@docRoot}google/auth/api-client.html">Accessing Google APIs</a>.
    <p>Use these APIs instead of the deprecated APIs:</p>
    <ul>
      <li>If you were previously using {@code ActivityRecognitionClient}, call
        <a href="{@docRoot}reference/com/google/android/gms/location/ActivityRecognition.html">{@code ActivityRecognition}</a> instead.</li>
      <li>If you were previously using {@code LocationClient}, call the APIs in the
        <a href="{@docRoot}reference/com/google/android/gms/location/package-summary.html">{@code com.google.android.gms.location} package</a> instead.</li>
      <li>If you were previously using {@code PlusClient}, call the APIs in the

<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"

    </ul>
  </li>

  <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.

    <li><strong>Wearables</strong> - The Wearable Data Layer API provides a
    communication channel between your handheld and wearable apps. The API
    consists of a set of data objects that the system can send and synchronize
    and listeners that notify your apps of important events from the other
    device.

<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>
