<h4>Google Technology</h4>
|
|
<p>Google Play services provides you with easy access to Google services and is tightly
|
|
integrated with the Android OS. Easy-to-use client libraries are provided for
|
|
each service that let you implement the functionality you want easier and faster.</p>

<h4>Standard Authorization</h4>
|
|
<p>All products in Google Play services share a common authorization API
|
|
that leverages the existing Google accounts on the device. You and your
|
|
users have a consistent and safe way to grant and receive OAuth2 access tokens
|
|
to Google services.</p>

<h4>Automatic Updates</h4>
|
|
<p>Devices running Android 2.2 and newer and that have the Google Play Store
|
|
app automatically receive updates to Google Play services. Enhance
|
|
your app with the most recent version of Google Play services without worrying
|
|
about your users' Android version.</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you to resolve any issues at runtime, such as a missing, disabled, or out-of-date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.

<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 2.2 (Froyo) 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 2.2 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>
