+
+@jd:body
+
+
+<p>Android powers hundreds of millions of mobile devices in more than 190
+countries around the world. It's the largest installed base of any mobile platform
+and growing fast&mdash;every day another million users power up their
+Android devices for the first time and start looking for apps, games,
+and other digital content. </p>
+
+
+<p>Android gives you a world-class platform for creating apps and games for
+Android users everywhere, as well as an open marketplace for distributing
+to them instantly.</p>
+
+<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 a 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 
+billions of 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.</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 billions of Android devices around the world,
+Google Play can be a growth engine for your business.</p>

You can look at a history of power events, approximate power use per UID and system component, and more.</p>

-<h3>
-  2. Build buzz

+
+<p>Google Play for Work is an extension of Google Play that lets Android for Work users browse and install apps. IT admins in a business using Android for Work choose which public and private apps are made available to users in their business. Businesses can use Google Play for Work to securely bulk deploy free apps to their employees or bulk purchase paid apps depending on their needs.</p>
+
+<p>As a Google Play developer, your free apps are automatically ready to be selected by Android for Work customers and made available to their workforces on Google Play for Work. However, to allow businesses access to bulk purchase your paid apps, you must opt-in and agree to the <a href="https://play.google.com/about/work/developer-distribution-agreement-addendum.html">Google Play for Work Addendum</a> to the Developer Distribution Agreement.</p>

+
+<ul>
+  <li>Follow best practices for security and manage user data properly. Businesses
+  are more conscious of data security and employee productivity, especially when it
+  comes to features that share information with other services.</li>
+  <li>Support the Work App Configuration framework to let an administrator remotely configure app settings such as:
+    <ul>
+      <li>Server address and protocol settings</li>
+      <li>The ability to switch features on and off</li>
+      <li>Sign-in credentials for your app's backend servers</li>
+      <li>Default user settings</li>
+    </ul>
+  </li>
+  <li>Request the minimum permissions that your app needs.</li>
+  <li>Make sure communication to your backend and data in your backend is secure.</li>
+  <li>Implement authorization policies that will minimize the number of your employees that can access user data.</li>
+  <li><a href={@docRoot}training/enterprise/app-compatibility.html">Offer compatibility with managed profile</a> and test that with the <a href="{@docRoot}samples/BasicManagedProfile/index.html">BasicManagedProfile sample app</a>.</li>

+
+<p>Free to install apps are automatically made available through Google Play for Work, but for paid apps:</p>
+
+<ul>
+<li>When you <a href="https://support.google.com/googleplay/android-developer/answer/113469">publish your app through the Developer Console</a>, opt in to distribute through Google Play for Work, so you agree to your app’s licenses being transferrable within a single business customer.</li>
+<li>Use the <a href="{@docRoot}}google/play/licensing/index.html">Licensing API to track which users have licenses assigned.</li>
+</ul> -->
+
+
+<h3 id="support">Provide support and maintenance</h3>
+
+<ul>
+<li>Consider offering enhanced support to cover extended hours or specific means of contact. Businesses are often willing to pay for this service.</li>
+<li>If you update the App Configuration / App Restrictions schema for your app, make sure it remains backward compatible. This is because it’s possible that different users will have different versions of your app (at least temporarily), and IT admin will want a consistent remote configuration experience between versions to ensure efficient management of apps in the field.</li>

+
+<p>Google sign-in is a trusted registration system that's familiar to users and
+consistent across devices. With minimal effort, you can improve your sign-in conversion
+with a fast and secure authentication option for users. And by using Google sign-in,
+you can offer users the option to send your app directly to their Android devices when
+they sign-in, without the need for them to visit the Play store. Using this approach,
+some developers have seen app installation acceptance rates of 40%.</p>
+
+<p>Get started with <a href="https://developers.google.com/identity/sign-in/android/">
+Google sign-in for Android</a> and then enable <a

-<p>Android Cloud to Device Messaging (C2DM) was officially deprecated on June 26, 2012, and will be
- shut down completely as of July 30, 2015.  <strong>C2DM developers are strongly encouraged to move
-  to Google Cloud Messaging (GCM)</strong>. GCM is the next generation of C2DM.</p>
-
-<p>This document is addressed to  C2DM developers who are moving to GCM. It describes the differences between GCM and C2DM, and explains how to migrate existing C2DM apps to GCM.</p>
-
-
-<h2 id="history">Historical Overview</h2>
-<p>C2DM  was launched in 2010 to help Android apps send data from servers to their applications. Servers can tell apps to contact the server directly, to fetch updated application or user data. The C2DM service handles all aspects of queueing of messages and delivery to the target application running on the target device.</p>
-<p>GCM replaces C2DM. The focus of GCM is as follows:</p>
-<ul>
-  <li> Ease of use. No sign-up forms.</li>
-  <li>No quotas.</li>
-  <li>GCM and C2DM stats are available through the <a href="http://play.google.com/apps/publish">Developer Console</a>.</li>
-  <li>Battery efficiency.</li>
-  <li>Rich set of new APIs.</li>
-</ul>
-<h2 id="diffs">How is GCM Different from C2DM?</h2>
-<p>GCM builds on the core foundation of C2DM. Here is what's different:</p>
-
-<dl>
-<dt><strong>Simple API Key</strong></dt>
-<dd>To use the GCM service, you need to obtain a Simple API Key from Google APIs console page. For more information, see <a href="gs.html">Getting Started</a>. Note that GCM <em>only</em> accepts Simple API Key&mdash;using ClientLogin or OAuth2 tokens will not work.
-</dd>
-<dt><strong>Sender ID</strong></dt>
-<dd>In C2DM, the Sender ID is an email address. In GCM, the Sender ID is a project number that you acquire from the API console, as described in <a href="gs.html#create-proj">Getting Started</a>. </dd>
-
-<dt><strong>JSON format</strong></dt>
-<dd>GCM HTTP requests support JSON format in addition to plain text. For more information, see the <a href="gcm.html#send-msg">Architectural Overview</a>.</dd>
-
-<dt><strong>Multicast messages</strong></dt>
-<dd>In GCM you can send the same message to multiple devices simultaneously. For example, a sports app wanting to deliver a score update to fans can now send the message to up to 1000 registration IDs in the same request (requires JSON). For more information, see the <a href="gcm.html#send-msg">Architectural Overview</a>.</dd>
-
-<dt><strong>Multiple senders</strong></dt>
-<dd>Multiple parties can send messages to the same app with one common registration ID. For more information, see <a href="adv.html#multi-senders">Advanced Topics</a>.</dd>
-
-<dt><strong>Time-to-live messages</strong></dt>
-<dd>Apps like video chat and calendar apps can send expiring invitation events with a time-to-live value between 0 and 4 weeks. GCM will store the messages until they expire. A message with a time-to-live value of 0 will not be stored on the GCM server, nor will it be throttled. For more information, see <a href="adv.html#ttl">Advanced Topics</a>.</dd>
-
-<dt><strong>Messages with payload</strong></dt>
-<dd>Apps can use &quot;messages with payload&quot; to deliver  messages of up to 4 Kb. This would be useful in a chat application, for example. To use this feature, simply omit the <code>collapse_key</code> parameter and messages will not be collapsed. GCM will store up to 100 messages. If you exceed that number, all messages will be discarded but you will receive a special message. If an application receives this message, it needs to sync with the server. For more information, see <a href="adv.html#collapsible">Advanced Topics</a>.</dd>
-
-<dt><strong>Canonical registration ID</strong></dt>
-<dd>There may be situations where the server ends up with 2 registration IDs for the same device. If the GCM response contains a registration ID, simply replace the registration ID you have with the one provided. With this feature your application doesn't need to send the device ID to your server anymore. For more information, see <a href="adv.html#canonical">Advanced Topics</a>.</dd>
-</dl>
-
-<h3 id="interop">Relationship between C2DM and GCM</h3>
-
-<p>C2DM and GCM are not interoperable. For example, you cannot post notifications from GCM to C2DM registration IDs, nor can you use C2DM registration IDs as GCM registration IDs. From your server-side application, you must keep track of whether a registration ID is from C2DM or GCM and use the proper endpoint. </p>
-
-<p>As you transition from C2DM to GCM, your server needs to be aware of whether a given registration ID
-contains an old C2DM sender or a new GCM project number. This is the approach we recommend: have the new app version (the one that uses GCM) send a bit along with the registration ID. This bit tells your server that this registration ID is for GCM. If you don't get the extra bit, you mark the registration ID as C2DM. Once no more valid registration IDs are marked as C2DM, you can complete the migration.</p>
-
-<h2 id="migrating">Migrating Your Apps</h2>
-<p>This section describes how to move existing C2DM apps to GCM.</p>
-<h3 id="client">Client changes</h3>
-<p>Migration is simple! Just re-register the client app for your target GCM-enabled platform. For
-  example, see <a href="{@docRoot}google/gcm/client.html#sample-register">Register for GCM</a></p>
-
-<p>After receiving a response from GCM, the registration ID obtained must be sent to the application server. When doing this, the application should indicate that it is sending a GCM registration ID so that the server can distinguish it from existing C2DM registrations.</p>
-
-<h3 id="server">Server changes</h3>
-<p>When the application server receives a GCM registration ID, it should store it and mark it as such.</p>
-<p>Sending messages to GCM devices requires a few changes:</p>
-<ul>
-  <li> The request should be sent to  a new endpoint: <code>https://android.googleapis.com/gcm/send</code>.</li>
-  <li>The Authorization header of the request should contain the API key generated during sign up. This key replaces the deprecated ClientLogin Auth token.</li>
-</ul>
-<p>For example:
-</p>
-<pre>Content-Type:application/json
-Authorization:key=AIzaSyB-1uEai2WiUapxCs2Q0GZYzPu7Udno5aA
-
-{
-  "registration_id" : "APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx...",
-  "data" : {
-    "Team" : "Portugal",
-    "Score" : "3",
-    "Player" : "Varela",
-  },
-}</pre>
-<p>For a detailed discussion of this topic and more examples, see the <a href="gcm.html#send-msg">Architectural Overview</a>.</p>
-<p>Eventually, once enough users of your application have migrated to the new service, you might want to take advantage of the new <a href="gcm.html#send-msg">JSON-formatted</a> requests that give access to the full set of features provided by GCM.</p>

-<p>The Google Cloud Messaging (GCM) Cloud Connection Server (CCS) is an XMPP endpoint that provides a
-persistent, asynchronous, bidirectional connection to Google servers. The
-connection can be used to send and receive messages between your server and
-your users' GCM-connected devices.</p>
-
-<p class="note"><strong>Note:</strong> The content in this document
-applies to <a href="http://developer.chrome.com/apps/cloudMessaging">
-GCM with Chrome apps</a> as well as Android.
-
-<p>You can continue to use the HTTP request mechanism to send messages to GCM
-servers, side-by-side with CCS which uses XMPP. Some of the benefits of CCS include:</p>
-
-<ul>
-  <li>The asynchronous nature of XMPP allows you to send more messages with fewer
-resources.</li>
-  <li>Communication is bidirectional&mdash;not only can your server send messages
-to the device, but the device can send messages back to your server.</li>
-  <li>The device can send messages back using the same connection used for receiving,
-thereby improving battery life.</li>
-</ul>
-
-<p>The upstream messaging (device-to-cloud) feature of CCS is part of the Google
-Play services platform. Upstream messaging is available through the
-<a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">
-{@code GoogleCloudMessaging}</a>
-APIs. For examples, see
-<a href="#implement">Implementing an XMPP-based App Server</a>.</p>
-
-<p class="note"><strong>Note:</strong> See the
-<a href="server-ref.html">Server Reference</a> for a list of all the message
-parameters and which connection server(s) supports them.</p>
-
-<h2 id="connecting">Establishing a Connection</h2>
-
-<p>CCS just uses XMPP as an authenticated transport layer, so you can use most
-XMPP libraries to manage the connection. For an example, see <a href="#smack">
-Java sample using the Smack library</a>.</p>
-
-<p>The CCS XMPP endpoint runs at {@code gcm.googleapis.com:5235}. When testing
-functionality (with non-production users), you should instead connect to
-{@code gcm-preprod.googleapis.com:5236} (note the different port). Regular
-testing on preprod (a smaller environment where the latest CCS builds run) is
-beneficial both for isolating real users from test code, as well as for early
-detection of unexpected behavior changes. Note that a connection receives upstream
-messages destined for its GCM sender ID, regardless of which environment (gcm or
-gcm-preprod) it is connected to. Therefore, test code connecting to
-{@code gcm-preprod.googleapis.com:5236} should use a different GCM sender ID to
-avoid upstream messages from production traffic being sent over test connections.</p>
-
-<p>The connection has two important requirements:</p>
-
-<ul>
-  <li>You must initiate a Transport Layer Security (TLS) connection. Note that
-  CCS doesn't currently support the <a href="http://xmpp.org/rfcs/rfc3920.html"
-  class="external-link" target="_android">STARTTLS extension</a>.</li>
-  <li>CCS requires a SASL PLAIN authentication mechanism using
-  {@code &lt;your_GCM_Sender_Id&gt;&#64;gcm.googleapis.com} (GCM sender ID)
-  and the API key as the password, where the sender ID and API key are the same
-  as described in <a href="gs.html">Getting Started</a>.</li>
-</ul>
-
-<p>If at any point the connection fails, you should immediately reconnect.
-There is no need to back off after a disconnect that happens after
-authentication.</p>
-

-
-<h2 id="format">Downstream Messages</h2>
-<p>Once the XMPP connection is established, CCS and your server use normal XMPP
-<code>&lt;message&gt;</code> stanzas to send JSON-encoded messages back and
-forth. The body of the <code>&lt;message&gt;</code> must be:</p>
-<pre>
-&lt;gcm xmlns:google:mobile:data&gt;
-    <em>JSON payload</em>
-&lt;/gcm&gt;
-</pre>
-
-<p>The JSON payload for regular GCM messages is similar to
-<a href="http.html#request">what the GCM http endpoint uses</a>, with these
-exceptions:</p>
-<ul>
-  <li>There is no support for multiple recipients.</li>
-  <li>{@code to} is used instead of {@code registration_ids}.</li>
-  <li>CCS adds the field {@code message_id}, which is required. This ID uniquely
-identifies the message in an XMPP connection. The ACK or NACK from CCS uses the
-{@code message_id} to identify a message sent from 3rd-party app servers to CCS.
-Therefore, it's important that this {@code message_id} not only be unique (per
-sender ID), but always present.</li>
-</ul>
-
-<p>In addition to regular GCM messages, control messages are sent, indicated by
-the {@code message_type} field in the JSON object. The value can be either
-'ack' or 'nack', or 'control' (see formats below). Any GCM message with an
-unknown {@code message_type} can be ignored by your server.</p>
-
-<p>For each device message your app server receives from CCS, it needs to send
-an ACK message.
-It never needs to send a NACK message. If you don't send an ACK for a message,
-CCS resends it the next time a new XMPP connection is established, unless the
-message expires first.
-</p>
-<p>CCS also sends an ACK or NACK for each server-to-device message. If you do not
-receive either, it means that the TCP connection was closed in the middle of the
-operation and your server needs to resend the messages. See
-<a href="#flow">Flow Control</a> for details.
-</p>
-
-<p class="note"><strong>Note:</strong> See the
-<a href="server-ref.html">Server Reference</a> for a list of all the message
-parameters and which connection server(s) supports them.</p>
-
-<h3 id="request">Request format</h3>
-
-<p>Here is an XMPP stanza containing the JSON message from a 3rd-party app server to CCS:
-
-</p>
-<pre>&lt;message id=&quot;&quot;&gt;
-  &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
-  {
-      &quot;to&quot;:&quot;REGISTRATION_ID&quot;,  // &quot;to&quot; replaces &quot;registration_ids&quot;
-      &quot;message_id&quot;:&quot;m-1366082849205&quot; // new required field
-      &quot;data&quot;:
-      {
-          &quot;hello&quot;:&quot;world&quot;,
-      }
-      &quot;time_to_live&quot;:&quot;600&quot;,
-      &quot;delay_while_idle&quot;: true/false,
-      &quot;delivery_receipt_requested&quot;: true/false
-  }
-  &lt;/gcm&gt;
-&lt;/message&gt;
-</pre>
-
-<h3 id="response">Response format</h3>
-
-<p>A CCS response can have 3 possible forms. The first one is a regular 'ack'
-message. But when the response contains an error, there are 2
-different forms the message can take, described below.</p>
-
-<h4 id="ack">ACK message</h4>
-
-<p>Here is an XMPP stanza containing the ACK/NACK message from CCS to 3rd-party app server:
-</p>
-<pre>&lt;message id=&quot;&quot;&gt;
-  &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
-  {
-      &quot;from&quot;:&quot;REGID&quot;,
-      &quot;message_id&quot;:&quot;m-1366082849205&quot;
-      &quot;message_type&quot;:&quot;ack&quot;
-  }
-  &lt;/gcm&gt;
-&lt;/message&gt;
-</pre>
-
-<h4 id="nack">NACK message</h4>
-
-<p>A NACK error is a regular XMPP message in which the {@code message_type} status
-message is &quot;nack&quot;. A NACK message contains:</p>
-<ul>
-<li>Nack error code.</li>
-<li>Nack error description.</li>
-</ul>
-
-<p>Below are some examples.</p>
-
-<p>Bad registration:</p>
-
-<pre>&lt;message&gt;
-  &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
-  {
-    &quot;message_type&quot;:&quot;nack&quot;,
-    &quot;message_id&quot;:&quot;msgId1&quot;,
-    &quot;from&quot;:&quot;SomeInvalidRegistrationId&quot;,
-    &quot;error&quot;:&quot;BAD_REGISTRATION&quot;,
-    &quot;error_description&quot;:&quot;Invalid token on 'to' field: SomeInvalidRegistrationId&quot;
-  }
-  &lt;/gcm&gt;
-&lt;/message&gt;</pre>
-
-<p>Invalid JSON:</p>
-
-<pre>&lt;message&gt;
- &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
- {
-   &quot;message_type&quot;:&quot;nack&quot;,
-   &quot;message_id&quot;:&quot;msgId1&quot;,
-   &quot;from&quot;:&quot;APA91bHFOtaQGSwupt5l1og&quot;,
-   &quot;error&quot;:&quot;INVALID_JSON&quot;,
-   &quot;error_description&quot;:&quot;InvalidJson: JSON_TYPE_ERROR : Field \&quot;time_to_live\&quot; must be a JSON java.lang.Number: abc&quot;
- }
- &lt;/gcm&gt;
-&lt;/message&gt;
-</pre>
-
-<p>Device Message Rate Exceeded:</p>
-
-<pre>&lt;message id=&quot;...&quot;&gt;
-  &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
-  {
-    &quot;message_type&quot;:&quot;nack&quot;,
-    &quot;message_id&quot;:&quot;msgId1&quot;,
-    &quot;from&quot;:&quot;REGID&quot;,
-    &quot;error&quot;:&quot;DEVICE_MESSAGE_RATE_EXCEEDED&quot;,
-    &quot;error_description&quot;:&quot;Downstream message rate exceeded for this registration id&quot;
-  }
-  &lt;/gcm&gt;
-&lt;/message&gt;
-</pre>
-
-<p>See the <a href="server-ref.html#table11">Server Reference</a> for a complete list of the
-NACK error codes. Unless otherwise
-indicated, a NACKed message should not be retried. Unexpected NACK error codes
-should be treated the same as {@code INTERNAL_SERVER_ERROR}.</p>
-
-<h4 id="stanza">Stanza error</h4>
-
-<p>You can also get a stanza error in certain cases.
-A stanza error contains:</p>
-<ul>
-<li>Stanza error code.</li>
-<li>Stanza error description (free text).</li>
-</ul>
-<p>For example:</p>
-
-<pre>&lt;message id=&quot;3&quot; type=&quot;error&quot; to=&quot;123456789@gcm.googleapis.com/ABC&quot;&gt;
-  &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
-     {&quot;random&quot;: &quot;text&quot;}
-  &lt;/gcm&gt;
-  &lt;error code=&quot;400&quot; type=&quot;modify&quot;&gt;
-    &lt;bad-request xmlns=&quot;urn:ietf:params:xml:ns:xmpp-stanzas&quot;/&gt;
-    &lt;text xmlns=&quot;urn:ietf:params:xml:ns:xmpp-stanzas&quot;&gt;
-      InvalidJson: JSON_PARSING_ERROR : Missing Required Field: message_id\n
-    &lt;/text&gt;
-  &lt;/error&gt;
-&lt;/message&gt;
-</pre>
-
-<h4 id="control">Control messages</h4>
-
-<p>Periodically, CCS needs to close down a connection to perform load balancing. Before it
-closes the connection, CCS sends a {@code CONNECTION_DRAINING} message to indicate that the connection is being drained
-and will be closed soon. "Draining" refers to shutting off the flow of messages coming into a
-connection, but allowing whatever is already in the pipeline to continue. When you receive
-a {@code CONNECTION_DRAINING} message, you should immediately begin sending messages to another CCS
-connection, opening a new connection if necessary. You should, however, keep the original
-connection open and continue receiving messages that may come over the connection (and
-ACKing them)&mdash;CCS handles initiating a connection close when it is ready.</p>
-
-<p>The {@code CONNECTION_DRAINING} message looks like this:</p>
-<pre>&lt;message&gt;
-  &lt;data:gcm xmlns:data=&quot;google:mobile:data&quot;&gt;
-  {
-    &quot;message_type&quot;:&quot;control&quot;
-    &quot;control_type&quot;:&quot;CONNECTION_DRAINING&quot;
-  }
-  &lt;/data:gcm&gt;
-&lt;/message&gt;</pre>
-
-<p>{@code CONNECTION_DRAINING} is currently the only {@code control_type} supported.</p>
-
-<!--Delivery receipts section-->
-
-<h3 id="receipts">Receive delivery receipts</h3>
-
-<p>You can get delivery receipts (sent from CCS to
-your 3rd party app server) when
-a device confirms that it received a message sent by CCS.</p>
-
-<p>To enable this feature, the message your 3rd-party app server sends to CCS must include
-a field called <code>&quot;delivery_receipt_requested&quot;</code>. When this field is set to
-<code>true</code>, CCS sends a delivery receipt when a device confirms that it received a particular message.</p>
-
-<p>Here is an XMPP stanza containing a JSON
-message with <code>&quot;delivery_receipt_requested&quot;</code> set to <code>true</code>:</p>
-
-<pre>&lt;message id=&quot;&quot;&gt;
-  &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
-  {
-      &quot;to&quot;:&quot;REGISTRATION_ID&quot;,
-      &quot;message_id&quot;:&quot;m-1366082849205&quot;
-      &quot;data&quot;:
-      {
-          &quot;hello&quot;:&quot;world&quot;,
-      }
-      &quot;time_to_live&quot;:&quot;600&quot;,
-      &quot;delay_while_idle&quot;: true,
-      <strong>&quot;delivery_receipt_requested&quot;: true</strong>
-  }
-  &lt;/gcm&gt;
-&lt;/message&gt;
-</pre>
-
-
-
-<p>Here is an example of the delivery receipt that CCS sends to tell your 3rd-party
-app server that a device received a message that CCS sent it:</p>
-
-</p>
-<pre>&lt;message id=&quot;&quot;&gt;
-  &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
-  {
-      &quot;category&quot;:&quot;com.example.yourapp&quot;, // to know which app sent it
-      &quot;data&quot;:
-      {
-         &#x201c;message_status&quot;:&quot;MESSAGE_SENT_TO_DEVICE&quot;,
-         &#x201c;original_message_id&#x201d;:&#x201d;m-1366082849205&#x201d;
-         &#x201c;device_registration_id&#x201d;: &#x201c;REGISTRATION_ID&#x201d;
-      },
-      &quot;message_id&quot;:&quot;dr2:m-1366082849205&quot;,
-      &quot;message_type&quot;:&quot;receipt&quot;,
-      &quot;from&quot;:&quot;gcm.googleapis.com&quot;
-  }
-  &lt;/gcm&gt;
-&lt;/message&gt;</pre>
-
-<p>Note the following:</p>
-
-<ul>
-  <li>The {@code &quot;message_type&quot;} is set to {@code &quot;receipt&quot;}.
-  <li>The {@code &quot;message_status&quot;} is set to {@code &quot;MESSAGE_SENT_TO_DEVICE&quot;},
-  indicating that the device received the message. Notice that in this case,
-{@code &quot;message_status&quot;} is not a field but rather part of the data payload.</li>
-  <li>The receipt message ID consists of the original message ID, but with a
-<code>dr2:</code> prefix. Your 3rd-party app server must send an ACK back with this ID,
-which in this example is {@code dr2:m-1366082849205}.</li>
-  <li>The original message ID, the device registration ID, and the status are inside the
-{@code &quot;data&quot;} field.</li>
-<li>If the connection between CCS and the device is poor, GCM may send multiple, duplicate delivery
- receipts. You can safely ignore such duplicates.</li>
-</ul>
-
-<h2 id="upstream">Upstream Messages</h2>
-
-<p>Using CCS and the
-<a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">
-{@code GoogleCloudMessaging}</a>
-API, you can send messages from a user's device to the cloud.</p>
-
-<p>Here is how you send an upstream message using the
-<a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">
-{@code GoogleCloudMessaging}</a>
-API. For a complete example, see <a href="client.html">Implementing GCM Client</a>:</p>
-
-<pre>GoogleCloudMessaging gcm = GoogleCloudMessaging.get(context);
-String GCM_SENDER_ID = "Your-Sender-ID";
-AtomicInteger msgId = new AtomicInteger();
-String id = Integer.toString(msgId.incrementAndGet());
-Bundle data = new Bundle();
-// Bundle data consists of a key-value pair
-data.putString("hello", "world");
-// "time to live" parameter
-// This is optional. It specifies a value in seconds up to 24 hours.
-int ttl = [0 seconds, 24 hours]
-
-gcm.send(GCM_SENDER_ID + "&#64;gcm.googleapis.com", id, ttl, data);
-</pre>
-
-<p>This call generates the necessary XMPP stanza for sending the upstream message.
-The message goes from the app on the device to CCS to the 3rd-party app server.
-The stanza has the following format:</p>
-
-<pre>&lt;message id=&quot;&quot;&gt;
-  &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
-  {
-      &quot;category&quot;:&quot;com.example.yourapp&quot;, // to know which app sent it
-      &quot;data&quot;:
-      {
-          &quot;hello&quot;:&quot;world&quot;,
-      },
-      &quot;message_id&quot;:&quot;m-123&quot;,
-      &quot;from&quot;:&quot;REGID&quot;
-  }
-  &lt;/gcm&gt;
-&lt;/message&gt;</pre>
-
-<p>Here is the format of the ACK expected by CCS from 3rd-party app servers in
-response to the above message:</p>
-
-<pre>&lt;message id=&quot;&quot;&gt;
-  &lt;gcm xmlns=&quot;google:mobile:data&quot;&gt;
-  {
-      &quot;to&quot;:&quot;REGID&quot;,
-      &quot;message_id&quot;:&quot;m-123&quot;
-      &quot;message_type&quot;:&quot;ack&quot;
-  }
-  &lt;/gcm&gt;
-&lt;/message&gt;</pre>
-
-
-<h2 id="flow">Flow Control</h2>
-
-<p>Every message sent to CCS receives either an ACK or a NACK response. Messages
-that haven't received one of these responses are considered pending. If the pending
-message count reaches 100, the 3rd-party app server should stop sending new messages
-and wait for CCS to acknowledge some of the existing pending messages as illustrated in
-figure 1:</p>
-
-<img src="{@docRoot}images/gcm/CCS-ack.png">
-
-<p class="img-caption">
-  <strong>Figure 1.</strong> Message/ack flow.
-</p>
-
-<p>Conversely, to avoid overloading the 3rd-party app server, CCS stops sending
-if there are too many unacknowledged messages. Therefore, the 3rd-party app server
-should "ACK" upstream messages, received from the client application via CCS, as soon as possible
-to maintain a constant flow of incoming messages. The aforementioned pending message limit doesn't
-apply to these ACKs. Even if the pending message count reaches 100, the 3rd-party app server
-should continue sending ACKs for messages received from CCS to avoid blocking delivery of new
-upstream messages.</p>
-
-<p>ACKs are only valid within the context of one connection. If the connection is
-closed before a message can be ACKed, the 3rd-party app server should wait for CCS
-to resend the upstream message before ACKing it again. Similarly, all pending messages for which an
-ACK/NACK was not received from CCS before the connection was closed should be sent again.
-</p>

-
-<p>A Google Cloud Messaging (GCM) Android client is a GCM-enabled app that runs on an
-Android device. To write your client code, we recommend that you use the
-<a href="{@docRoot}reference/com/google/android/gms/gcm/package-summary.html">
-{@code GoogleCloudMessaging}</a> API.</p>
-
-<p>Here are the requirements for running a GCM Android client:</p>
-
-<ul>
-  <li>At a bare minimum, GCM requires devices running Android 2.2 or higher that also have the
-Google Play Store application installed, or an emulator running Android 2.2
-with Google APIs. Note that you are not limited to deploying your
-Android applications through Google Play Store.</li>
-  <li>However, if you want to continue to use new GCM features that are distributed
-through Google Play Services, the device must be running Android 2.3 or higher, or
-you can use an emulator running Android 2.3 with Google APIs.</li>
-<li>On Android devices, GCM uses an existing connection for Google services. For
-pre-3.0 devices, this requires users to set up their Google accounts on their mobile
-devices. A Google account is not a requirement on devices running Android 4.0.4 or higher.</li>
-
-</ul>
-
-<p>A full GCM implementation requires both a client implementation and a server
-implementation. For more
-information about implementing the server side, see <a href="server.html">
-Implementing GCM Server</a>.</p>
-
-<p>The following sections walk you through the steps involved in writing a GCM
-client-side application. Your client app can be arbitrarily complex, but at bare
-minimum, a GCM client app must include code to register (and thereby get a
-registration ID), and a broadcast receiver to receive messages sent by GCM.
-</p>
-
-<h2 id="play-services">Step 1: Set Up Google Play Services</h2>
-
-<p>To write your client application, use the
-<a href="{@docRoot}reference/com/google/android/gms/gcm/package-summary.html">
-{@code GoogleCloudMessaging}</a> API.
-To use this API, you must set up your project to use the Google Play services SDK,
-as described in <a href="/google/play-services/setup.html">Setup Google Play
-Services SDK</a>.</p>
-
-<p class="note"><strong>Caution:</strong> When you add the Play Services library to
-your project, be sure to add it <em>with resources</em>, as described in
-<a href="{@docRoot}google/play-services/setup.html#Setup">
-Setup Google Play Services SDK</a>. The key point is that you must
-<em>reference</em> the library&mdash;simply adding a {@code .jar} file to
-your Eclipse project will not work. You must follow the directions
-for referencing a library, or your app won't be able to access
-the library's resources, and it won't run properly.
-If you're using Android Studio, this is the string to add to the
-{@code dependency} section of your application's {@code build.gradle} file:</p>
-
-<pre>dependencies {
-  compile "com.google.android.gms:play-services:3.1.+"
-}
-</pre>
-
-
-<h2 id="manifest">Step 2: Edit Your Application's Manifest</h2>
-
-<p>Add the following to your application's manifest:</p>
-<ul>
-  <li>The <code>com.google.android.c2dm.permission.RECEIVE</code> permission so
-the Android application can register and receive messages.</li>
-  <li>The <code>android.permission.INTERNET</code> permission so the Android
-application can send the registration ID to the 3rd party server.</li>
-  <li>The <code>android.permission.WAKE_LOCK</code> permission so the application
-can keep the processor from sleeping when a message is received. Optional&mdash;use
-only if the app wants to keep the device from sleeping.</li>
-  <li>An <code>applicationPackage + &quot;.permission.C2D_MESSAGE&quot;</code>
-permission to prevent other Android applications from registering and receiving
-the Android application's messages. The permission name must exactly match this
-pattern&mdash;otherwise the Android application will not receive the messages.</li>
-   <li>A receiver for <code>com.google.android.c2dm.intent.RECEIVE</code>, with
-the category set
-as <code>applicationPackage</code>. The receiver should require the
-<code>com.google.android.c2dm.permission.SEND</code> permission, so that only the GCM
-Framework can send a message to it. If your app uses an {@link android.app.IntentService}
-(not required, but a common pattern), this receiver should be an instance of
-{@link android.support.v4.content.WakefulBroadcastReceiver}.
-A {@link android.support.v4.content.WakefulBroadcastReceiver} takes care of
-creating and managing a
-<a href="{@docRoot}reference/android/os/PowerManager.html#PARTIAL_WAKE_LOCK">
-partial wake lock</a> for your app.</li>
-
-<li>A {@link android.app.Service} (typically an {@link android.app.IntentService})
-to which the {@link android.support.v4.content.WakefulBroadcastReceiver} passes off
-the work of handling the GCM message, while ensuring that the device does not
-go back to sleep in the process. Including an {@link android.app.IntentService} is
-optional&mdash;you could choose to process your messages in a regular
-{@link android.content.BroadcastReceiver} instead, but realistically, most apps will
-use a {@link android.app.IntentService}.
-</li>
-  <li>If the GCM feature is critical to the Android application's function, be sure to
-set <code>android:minSdkVersion=&quot;8&quot;</code> or higher in the manifest. This
-ensures that the Android application cannot be installed in an environment in which it
-could not run properly. </li>
-</ul>
-
-<p>Here are excerpts from a sample manifest that supports GCM:</p>
-
-<pre class="prettyprint pretty-xml">
-&lt;manifest package="com.example.gcm" ...&gt;
-
-    &lt;uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17"/&gt;
-    &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
-    &lt;uses-permission android:name="android.permission.GET_ACCOUNTS" /&gt;

-        android:protectionLevel="signature" /&gt;
-    &lt;uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" /&gt;
-
-    &lt;application ...&gt;
-        &lt;receiver
-            android:name=".GcmBroadcastReceiver"
-            android:permission="com.google.android.c2dm.permission.SEND" &gt;
-            &lt;intent-filter&gt;
-                &lt;action android:name="com.google.android.c2dm.intent.RECEIVE" /&gt;
-                &lt;category android:name="com.example.gcm" /&gt;
-            &lt;/intent-filter&gt;
-        &lt;/receiver&gt;
-        &lt;service android:name=".GcmIntentService" /&gt;
-    &lt;/application&gt;
-
-&lt;/manifest&gt;
-</pre>
-
-<h2 id="app"> Step 3: Write Your Application</h2>
-
-<p>Finally, write your application. This section features a sample client
-application that illustrates how to use the
-<a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">
-{@code GoogleCloudMessaging}</a> API. The sample consists of a main activity
-({@code DemoActivity}), a {@link android.support.v4.content.WakefulBroadcastReceiver}
-({@code GcmBroadcastReceiver}), and an {@link android.app.IntentService}
-({@code GcmIntentService}). You can find the complete source code for this sample at the
-<a href="http://code.google.com/p/gcm">open source site</a>.</p>
-
-<p>Note the following:</p>
-
-<ul>
-  <li>Among other things, the sample illustrates registration and upstream
-(device-to-cloud) messaging. Upstream messaging only applies to apps that are running against a
-<a href="ccs.html">CCS</a> (XMPP) server; HTTP-based servers don't support upstream messaging.</li>
-  <li>The <a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">
-  {@code GoogleCloudMessaging}</a>
-registration APIs replace the old registration process, which was based on the
-now-obsolete client helper library. While the old registration process still works,
-we encourage you to use the newer
-<a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">
-{@code GoogleCloudMessaging}</a>
-registration APIs, regardless of your underlying server.</li>
-</ul>
-
-<h3 id="sample-play">Check for Google Play Services APK</h3>
-
-<p>As described in <a href="{@docRoot}google/play-services/setup.html">
-Setup Google Play Services SDK</a>, apps that rely on the Play Services SDK
-should always check the device for a compatible Google Play services APK before
-accessing Google Play services features. In the sample app this check is done in
-two places: in the main activity's {@code onCreate()} method, and in its
-{@code onResume()} method. The check in {@code onCreate()} ensures that the app
-can't be used without a successful check. The check in {@code onResume()} ensures
-that if the user returns to the running app through some other means, such as
-through the back button, the check is still performed. If the
-device doesn't have a compatible Google Play services APK, your app can call
-{@code GooglePlayServicesUtil.getErrorDialog()} to allow users to download the
-APK from the Google Play Store or enable it in the device's system settings.
-For example:</p>
-
-<pre>private final static int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
-...
-&#64;Override
-public void onCreate(Bundle savedInstanceState) {
-    super.onCreate(savedInstanceState);

-
-<h4 id="reg-errors">Handle registration errors</h4>
-
-<p>As stated above, an Android app must register with GCM servers and get a registration ID
-before it can receive messages. A given registration ID is not guaranteed to last indefinitely,
-so the first thing your app should always do is check to make sure it has a valid
-registration ID (as shown in the code snippets above).</p>
-
-<p>In addition to confirming that it has a valid registration ID, your app should be prepared to handle
-the registration error {@code TOO_MANY_REGISTRATIONS}. This error indicates that the device
-has too many apps registered with GCM. The error only occurs in cases where there are
-extreme numbers of apps, so it should not affect the average user. The remedy is to prompt
-the user to delete some of the other client apps from the device to make
-room for the new one.</p>
-
-<h3 id="sample-receive">Receive a downstream message</h3>
-
-<p>As described above in <a href="#manifest">Step 2</a>, the app includes a
-{@link android.support.v4.content.WakefulBroadcastReceiver} for the <code>com.google.android.c2dm.intent.RECEIVE</code>
-intent. A broadcast receiver is the mechanism GCM uses to deliver messages. </p>
-<p>A {@link android.support.v4.content.WakefulBroadcastReceiver} is a special type of
-broadcast receiver that takes care of
-creating and managing a
-<a href="{@docRoot}reference/android/os/PowerManager.html#PARTIAL_WAKE_LOCK">
-partial wake lock</a> for your app.
-It passes off the work of processing the GCM message to a
-{@link android.app.Service} (typically an
-{@link android.app.IntentService}), while ensuring that the device does not
-go back to sleep in the transition. If you don't hold a wake lock while transitioning
-the work to a service, you are effectively allowing the device to go back to sleep before
-the work completes. The net result is that the app might not finish processing
-the GCM message until some arbitrary point in the future, which is not what you want.</p>
-
-<p class="note"><strong>Note:</strong> Using {@link android.support.v4.content.WakefulBroadcastReceiver}
-is not a requirement. If you have a relatively simple app that doesn't require
-a service, you can intercept the GCM message in a regular {@link android.content.BroadcastReceiver}
-and do your processing there. Once you get the intent that GCM passes into
-your broadcast receiver's {@code onReceive()} method, what you do with it
-is up to you.</p>
-
-<p>This snippet starts {@code GcmIntentService} with the method
-{@link android.support.v4.content.WakefulBroadcastReceiver#startWakefulService startWakefulService()}.
-This method is comparable to {@link android.content.Context#startService startService()}, except that
-the {@link android.support.v4.content.WakefulBroadcastReceiver} is holding a
-wake lock when the service starts. The intent that is passed with
-{@link android.support.v4.content.WakefulBroadcastReceiver#startWakefulService startWakefulService()}
-holds an extra identifying the wake lock:</p>
-
-
-<pre>public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
-    &#64;Override
-    public void onReceive(Context context, Intent intent) {
-        // Explicitly specify that GcmIntentService will handle the intent.
-        ComponentName comp = new ComponentName(context.getPackageName(),
-                GcmIntentService.class.getName());
-        // Start the service, keeping the device awake while it is launching.
-        startWakefulService(context, (intent.setComponent(comp)));
-        setResultCode(Activity.RESULT_OK);
-    }
-}</pre>
-
-<p>The intent service shown below does the actual work of handling the GCM
-message. When the service is finished, it calls
-{@link android.support.v4.content.WakefulBroadcastReceiver#completeWakefulIntent GcmBroadcastReceiver.completeWakefulIntent()}
-to release the wake lock. The
-{@link android.support.v4.content.WakefulBroadcastReceiver#completeWakefulIntent completeWakefulIntent()}
-method has as its parameter the same intent that was
-passed in from the {@link android.support.v4.content.WakefulBroadcastReceiver}.
-</p>
-
-<p>This snippet processes the GCM message based on message type, and posts the
-result in a notification. But what you do with GCM messages in your app is up to
-you&mdash;the possibilities are endless. For example, the message might be a ping,
-telling the app to sync to a server to retrieve new content, or it might be a
-chat message that you display in the UI.</p>

-<p class="note"><strong>Note:</strong> This tutorial describes how to develop GCM-enabled apps using the helper libraries. This is just one approach. For a more comprehensive discussion of the available APIs and development paths, see <a href="gs.html">Getting Started</a>.
-
-<p>The Google Cloud Messaging (GCM) Demo demonstrates how to use the Google Cloud Messaging framework in your Android application. This tutorial walks you through setting up and running the demo.</p>
-
-
-<p>This demo consists of the following pieces: </p>
-<ul>
-  <li>A web server containing a page where you can send messages.</li>
-  <li>An Android application that receives and displays such messages.</li>
-</ul>
-<p>See the <a href="{@docRoot}reference/com/google/android/gcm/package-summary.html">reference</a> for the client and server helper libraries used in this demo.</p>
-
-<p>The sections below describe how to download the demo code and helper libraries from the SDK Manager. The demo code and helper libraries are also available at the <a href="http://code.google.com/p/gcm">open source site</a>.
-
-<h2 id="requirements">Requirements</h2>
-<p>For the web server:</p>
-<ul>
-  <li> <a href="http://ant.apache.org/">Ant 1.8</a> (it might work with earlier versions, but it's not guaranteed).</li>
-  <li>One of the following:
-    <ul>
-      <li>A running web server compatible with Servlets API version 2.5, such as <a href="http://tomcat.apache.org/">Tomcat 6</a> or <a href="http://jetty.codehaus.org/">Jetty</a>, or</li>
-      <li><a href="http://code.google.com/appengine/">Java App Engine SDK</a> version 1.6 or later.</li>
-    </ul>
-  </li>
-  <li>A Google account registered to use GCM.</li>
-  <li>The API  key for that account.</li>
-</ul>
-<p>For the Android application:</p>
-<ul>
-  <li>Emulator (or device) running Android 2.2 with Google APIs.</li>
-  <li>The Google API project number of the account registered to use GCM.</li>
-</ul>
-<h2 id="gcm-setup">Setting Up GCM</h2>
-<p>Before proceeding with the server and client setup, it's necessary to register a Google account with the Google API Console, enable Google Cloud Messaging in GCM, and obtain an API key from the <a href="https://code.google.com/apis/console">Google API Console</a>.</p>
-<p>For instructions on how to set up GCM, see <a href="gs.html">Getting Started</a>.</p>
-
-
-<h2 id="server-setup">Setting Up the Server</h2>
-<p>This section describes the different options for setting up a server.</p>
-<h3 id="webserver-setup">Using a standard web server</h3>
-<p>To set up the server using a standard, servlet-compliant web server:</p>
-<ol>
-  <li> From the SDK Manager, install <strong>Extras &gt; Google Cloud Messaging for Android Library</strong>.
-    
-    
-    <p>This creates a <code>gcm</code> directory under <code><em>YOUR_SDK_ROOT</em>/extras/google/</code> containing these subdirectories: <code>gcm-client</code>, <code>gcm-server</code>, <code>samples/gcm-demo-client</code>, <code>samples/gcm-demo-server</code>, and <code>samples/gcm-demo-appengine</code>.</p>
-
-<p class="note"><strong>Note:</strong> If you don't see <strong>Extras &gt; Google Cloud Messaging for Android Library</strong> in the SDK Manager, make sure you are running version 20 or higher. Be sure to restart the SDK Manager after updating it.</p>
-  </li>
-
-  <li>In a text editor, edit the <code>samples/gcm-demo-server/WebContent/WEB-INF/classes/api.key</code> and replace the existing text with the API key obtained above.</li>
-  <li>In a shell window, go to the <code>samples/gcm-demo-server</code> directory.</li>
-  <li>Generate the server's WAR file by running <code>ant war</code>:</li>
-  
-  <pre class="prettyprint">$ ant war
-
-Buildfile:build.xml
-
-init:
-   [mkdir] Created dir: build/classes
-   [mkdir] Created dir: dist
-
-compile:
-   [javac] Compiling 6 source files to build/classes
-
-war:
-     [war] Building war: <strong>dist/gcm-demo.war</strong>
-
-BUILD SUCCESSFUL
-Total time: 0 seconds
-</pre>
-  
-  <li>Deploy the <code>dist/gcm-demo.war</code> to your running server. For instance, if you're using Jetty, copy <code>gcm-demo.war</code> to the <code>webapps</code> directory of the Jetty installation.</li>
-  <li>Open the server's main page in a browser. The URL depends on the server you're using and your machine's IP address, but it will be something like <code>http://192.168.1.10:8080/gcm-demo/home</code>, where <code>gcm-demo</code> is the application context and <code>/home</code> is the path of the main servlet.
-    
-  </li>
-</ol>
-<p class="note"><strong>Note:</strong> You can get the IP by running <code>ifconfig</code> on Linux or MacOS, or <code>ipconfig</code> on Windows. </p>
-
-<p> You server is now ready.</p>
-<h3 id="appengine-setup">Using App Engine for Java</h3>
-
-<p>To set up the server using a standard App Engine for Java:</p>
-<ol>
-  <li> From the SDK Manager, install <strong>Extras &gt; Google Cloud Messaging for Android Library</strong>.
-    <p>This creates a <code>gcm</code> directory under <code><em>YOUR_SDK_ROOT</em>/extras/google/</code> containing these subdirectories: <code>gcm-client</code>, <code>gcm-server</code>, <code>samples/gcm-demo-client</code>, <code>samples/gcm-demo-server</code>, and <code>samples/gcm-demo-appengine</code>.</p>
-  </li>
-  <li>In a text editor, edit <code>samples/gcm-demo-appengine/src/com/google/android/gcm/demo/server/ApiKeyInitializer.java</code> and replace the existing text with the API key obtained above.
-  <p class="note"><strong>Note:</strong> The API key value set in that class will be used just once to create a persistent entity on App Engine. If you deploy the application, you can use App Engine's <code>Datastore Viewer</code> to change it later.</p>
-  
-  </li>
-  <li>In a shell window, go to the <code>samples/gcm-demo-appengine</code> directory.</li>
-  <li>Start the development App Engine server by <code>ant runserver</code>, using the <code>-Dsdk.dir</code> to indicate the location of the App Engine SDK and <code>-Dserver.host</code> to set your server's hostname or IP address:</li>
-
-<pre class="prettyprint">

-  </li>
-  <li>Using a text editor, open  <code>samples/gcm-demo-client/src/com/google/android/gcm/demo/app/CommonUtilities.java</code> and set the proper values for the <code>SENDER_ID</code> and <code>SERVER_URL</code> constants. For example:</li>
-
-<pre class="prettyprint pretty-java">

-static final String SENDER_ID = &quot;4815162342&quot;;</pre>
-<p>Note that the <code>SERVER_URL</code> is the URL for the server and the application's context (or just server, if you are using App Engine), and it does not include the forward slash (<code>/</code>). Also note that <code>SENDER_ID</code> is the Google API project number you obtained in the server setup steps above.</p>
-
-  <li>In a shell window, go to the <code>gcm-demo-client</code> directory.</li>

-<p>Google Cloud Messaging (GCM) is a free service that enables developers
-to send downstream messages (from servers to GCM-enabled client apps), and
-upstream messages (from the GCM-enabled client apps to servers).
-This could be a lightweight message telling the client app
-that there is new data to be fetched from the server (for instance, a "new email"
-notification informing the app that it is out of sync with the back end),
-or it could be a message containing up to 4kb of payload
-data (so apps like instant messaging can consume the message directly). The GCM
-service handles all aspects of queueing of messages and delivery to and from
-the target client app.</p>
-
-
-<h2 id="key">Key Concepts</h2>
-
-<p>This table summarizes the key terms and concepts involved in GCM. It is
-divided into these categories:</p>
-<ul>
-  <li><strong>Components</strong> &mdash; The entities that play a primary role in
-GCM.</li>
-  <li><strong>Credentials</strong> &mdash; The IDs and tokens that are used in
-GCM to ensure that all parties have been authenticated, and
-that the message is going to the correct place.</li>

-<h2 id="arch">Architectural Overview</h2>
-
-<p>A GCM implementation includes a Google-provided
-connection server, a 3rd-party app server that interacts with the connection
-server, and a GCM-enabled client app. For example, this diagram shows GCM
-communicating with a client app on an Android device:</p>
-
-<img src="{@docRoot}images/gcm/GCM-arch.png">
-
-<p class="img-caption">
-  <strong>Figure 1.</strong> GCM Architecture.
-</p>
-
-<p>This is how these components interact:</p>
-<ul>
-  <li>Google-provided <strong>GCM Connection Servers</strong> take messages from
-a 3rd-party app server and send these messages to a
-GCM-enabled client app (the &quot;client app&quot;).
-Currently Google provides connection servers for <a href="http.html">HTTP</a>
-and <a href="ccs.html">XMPP</a>.</li>
-  <li>The <strong>3rd-Party App Server</strong> is a component that you
-implement to work with your chosen GCM connection server(s). App servers send
-messages to a GCM connection server; the connection server enqueues and stores the
-message, and then sends it to the client app.
-For more information, see <a href="server.html">Implementing GCM Server</a>.</li>
-  <li>The <strong>Client App</strong> is a GCM-enabled client app.
-To receive GCM messages, this app must register with GCM and get a
-registration ID. If you are using the <a href="ccs.html">XMPP</a> (CCS) connection
-server, the client app can send "upstream" messages back to the 3rd-party app server.
-For more information on how to implement the client app, see
-the documentation for your platform.</li>
-</ul>
-
-<h2 id="lifecycle">Lifecycle Flow</h2>
-
-<ul>
-  <li><strong>Register to enable GCM</strong>. A client app registers to receive messages.
-For more discussion, see <a href="#register">Register to enable GCM</a>.</li>
-  <li><strong>Send and receive downstream messages</strong>.
-  <ul>
-     <li>Send a message. A 3rd-party app server sends messages to the client app:
-       <ol>
-         <li>The 3rd-party app server <a href="server.html#send-msg">sends a message</a>
-to GCM connection servers.</li>
-         <li>The GCM connection server enqueues and stores the message if the device is offline.</li>
-         <li>When the device is online, the GCM connection server sends the message to the device. </li>
-         <li>On the device, the client app receives the message according to the platform-specific implementation.
-See your platform-specific documentation for details.</li>
-       </ol>
-    </li>
-  <li>Receive a message. A client app
-receives a message from a GCM server. See your platform-specific documentation for details
-on how a client app in that environment processes the messages it receives.</li>
-  </ul>
-</li>
-
-  <li><strong>Send and receive upstream messages</strong>. This feature is only available if
-you're using the <a href="ccs.html">XMPP Cloud Connection Server</a> (CCS).
-<ul>
-     <li>Send a message. A client app sends messages to the 3rd-party app server:
-      <ol>
-        <li>On the device, the client app sends messages to XMPP (CCS).See your platform-specific
-          documentation for details on how a client app can send a message to XMPP (CCS).</li>
-        <li>XMPP (CCS) enqueues and stores the message if the server is disconnected.</li>
-        <li>When the 3rd-party app server is re-connected, XMPP (CCS) sends the message to the 3rd-party app server.</li>
-      </ol>
-    </li>
-  <li>Receive a message. A 3rd-party app server receives a message from XMPP (CCS) and then does the following:
-      <ol>
-        <li>Parses the message header to verify client app sender information.
-        <li>Sends "ack" to GCM XMPP connection server to acknowledge receiving the message.
-        <li>Optionally parses the message payload, as defined by the client app.
-      </ol>
-</li>
-</ul>
-
-</li>
-
-
-</ul>
-
-<h2 id="reg">Register to enable GCM</h2>
-
-<p>Regardless of the platform you're developing on, the first step
-a client app must do is register with GCM. This section covers some of the general
-best practices for registration and unregistration. See your platform-specific docs for
-details on writing a GCM-enabled client app on that platform.</p>
-
-<h3 id="reg-state">Keeping the Registration State in Sync</h3>
-<p>Whenever the app registers as described in
-<a href="{@docRoot}google/gcm/client.html">Implementing GCM Client</a>,
-it should save the registration ID for future use, pass it to the
-3rd-party server to complete the registration, and keep track of
-whether the server completed the registration. If the server fails
-to complete the registration, the client app should retry passing the
-registration ID to 3rd-party app server to complete the registration.
-If this continues to fail, the client app should unregister from GCM.</p>
-
-<p>There are also two other scenarios that require special care:</p>
-<ul>
-  <li>Client app update</li>
-  <li>Backup and restore
-  </li>
-</ul>
-<p><bold>Client app update:</bold> When a client app is updated, it should invalidate its existing registration
-ID, as it is not guaranteed to work with the new version.  The recommended way to achieve
-this validation is by storing the current app version when a registration
-ID is stored. Then when the app starts, compare the stored value with
-the current app version. If they do not match, invalidate the stored data
-and start the registration process again.</p>
-
-<p><bold>Backup and restore: </bold> You should not save the registration ID when an app is
-backed up. This is because the registration ID could become invalid by the time
-the app is restored, which would put the app in an invalid state
-(that is, the app thinks it is registered, but the server and GCM do not
-store that registration ID anymore&mdash;thus the app will not get more
-messages). The best practice is to initiate the registration process as if the app has been
-installed for the first time.</p>
-
-<h4 id="canonical">Canonical IDs</h4>
-<p>If a bug in the app triggers multiple
-registrations for the same device, it can be hard to reconcile state and you might
-end up with duplicate messages.</p>
-<p>GCM provides a facility called &quot;canonical registration IDs&quot; to easily
-recover from these situations. A canonical registration ID is defined to be the ID
-of the last registration requested by your app. This is the ID that the
-server should use when sending messages to the device.</p>
-<p>If later on you try to send a message using a different registration ID, GCM
-will process the request as usual, but it will include the canonical registration
-ID in the <code>registration_id</code> field of the response. Make sure to replace
-the registration ID stored in your server with this canonical ID, as eventually
-the ID you're using will stop working.</p>
-
-<h3 id="retry">Automatic Retry Using Exponential Back-Off</h3>
-
-<p>When registration or unregistration fails, the app should retry the failed operation.</p>
-<p>In the simplest case, if your app attempts to register and GCM is not a
-fundamental part of the app, the app could simply ignore the error
-and try to register again the next time it starts. Otherwise, it should retry the
-previous operation using exponential back-off. In exponential back-off, each time
-there is a failure, it should wait twice the previous amount of time before trying
-again.
-</p>
-
-<h3 id="unreg">Unregistration</h3>
-
-<p>This section explains when you should unregister in GCM and what happens
-when you do.</p>
-
-<h4 id="unreg-why">Why you should rarely unregister</h4>
-
-<p>You should only need to unregister in rare cases, such as
-if you want an app to stop receiving messages, or if you suspect that the registration ID has
-been compromised. In general, once an app has a registration ID, you shouldn't need
-to change it.</p>
-
-<p>In particular, you should never unregister your app as a mechanism for
-logout or for switching between users, for the following reasons:</p>
-
-<ul>
-  <li>A registration ID isn't associated with a particular
-  logged in user. If you unregister and then re-register, GCM may return the same
-  ID or a different ID&mdash;there's no guarantee either way.</li>
-
-  <li>Unregistration may take up to 5 minutes to propagate.</li>
-  <li>After unregistration, re-registration may again take up to 5 minutes to
-propagate. During this time messages may be rejected due to the state of being
-unregistered, and after all this, messages may still go to the wrong user.</li>
-</ul>
-
-
-<p>To make sure that messages go to the intended user:</p>
-
-<ul>
-  <li>Your app server can maintain a mapping between the current user
-and the registration ID.</li>
-  <li>The app can then check to ensure that messages it
-receives match the logged in user.</li>
-</ul>
-
-
-<h4 id="unreg-how">How unregistration works</h4>
-
-<p>A client app can be automatically unregistered after it is uninstalled.
-However, this process does not happen right away. What happens in
-this scenario is as follows:</p>
-<ol>
-  <li>The end user uninstalls the client app.</li>
-  <li>The 3rd-party app server sends a message to GCM server.</li>
-  <li>The GCM server sends the message to the GCM client on the device.</li>
-  <li>The GCM client on the device receives the message and detects that the client app has been
-   uninstalled; the detection details depend on the platform on which the client app is running.
-</li>
-  <li>The GCM client on the device informs the GCM server that the client app was uninstalled.</li>
-  <li>The GCM server marks the registration ID for deletion.</li>
-  <li>The 3rd-party app server sends a message to  GCM.</li>
-  <li>The GCM returns a <code>NotRegistered</code> error message to the 3rd-party app server.</li>
-  <li>The 3rd-party app server deletes the registration ID.
-  </li>
-</ol>
-
-<p>Note that it might take a while for the registration ID be completely removed
-from GCM. Thus it is possible that messages sent during step 7 above gets a valid
-message ID as response, even though the message will not be delivered to the client app.
-Eventually, the registration ID will be removed and the server will get a
-<code>NotRegistered</code> error, without any further action being required from
-the 3rd-party server (this scenario happens frequently while an app is
-being developed and tested).</p>

-<p>This document tells you how to get started setting up a Google Cloud Messaging
-(GCM) implementation.
-Before you begin, make sure to <a href="/google/play-services/setup.html">set up
-the Google Play Services SDK</a>. You need this SDK to use the
-<a href="{@docRoot}reference/com/google/android/gms/gcm/package-summary.html">
-GCM APIs</a>.</p>
-
-<h2 id="create-proj">Creating a Google API project</h2>
-<p>To create a Google API project:</p>
-<ol>
-  <li>Open the <a href="https://cloud.google.com/console">Google Developers Console</a>.
-  </li>
-  <li>If you haven't created an API project yet, click <strong>Create Project</strong>.</li>
-
- <li>Supply a project name and click <strong>Create</strong>.
-
-<p>Once the project has been created, a page appears that displays your project ID and
-project number. For example, <strong>Project Number: 670330094152</strong>.</p></li>
-
-  <li>Copy down your project number. You will use it later on as the
-  <a href="{@docRoot}google/gcm/gcm.html#senderid">GCM sender ID</a>.</li>
-
-</ol>
-<h2 id="gcm-service">Enabling the GCM Service</h2>
-<p>To enable the GCM service:</p>
-<ol>
-  <li>In the sidebar on the left, select <strong>APIs &amp; auth</strong>. </li>
-  <li>In the displayed list of APIs, turn the <strong>Google Cloud Messaging for Android
-  </strong> toggle to ON.</li>
-
-</ol>
-<h2 id="access-key">Obtaining an API Key</h2>
-<p>To obtain an API  key:</p>
-<ol>
- <li>In the sidebar on the left, select <strong>APIs &amp; auth > Credentials</strong>.</li>
-
- <li>Under <strong>Public API access</strong>, click <strong>Create new key</strong>.</li>
-
-<li>In the <strong>Create a new key</strong> dialog, click <strong>Server key</strong>.</li>

-<p>This document describes how to write an Android application and the  server-side logic, using the client and server <a href="{@docRoot}reference/com/google/android/gcm/package-summary.html">helper libraries</a> provided by GCM.</p> 
-
-<p>The helper libraries are one option for creating an Android application that uses GCM. You can alternatively use the approach described in the <a href="{@docRoot}google/gcm/gcm.html#writing_apps">GCM Architectural Overview</a>. If you need to perform upstream messaging, you must use the <a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">GoogleCloudMessaging</a> APIs, and <a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">GoogleCloudMessaging</a> also provides a streamlined registration process.</p>
-
-<p>For information on how to get started creating an Android GCM application and an example of how to use the <a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">GoogleCloudMessaging</a> APIs, see <a href="{@docRoot}google/gcm/gs.html">Getting Started</a>.</p>
-
-<h2 id="libs">Installing the Helper Libraries</h2>
-<p>To perform the steps described in the following sections, you must first install the 
-<a href="{@docRoot}reference/com/google/android/gcm/package-summary.html">helper libraries</a>. Note that while using the helper libraries is recommended, it is not required. See the <a href="gcm.html#writing_apps">GCM Architectural Overview</a> for a description of how to write apps without using the helper libraries.
-
-<p>To install the helper libraries, choose 
-<strong>Extras &gt; Google Cloud Messaging for Android Library</strong>
-from the SDK Manager. This creates a <code>gcm</code> directory under
-<code><em>YOUR_SDK_ROOT</em>/extras/google/</code> containing these
-subdirectories: <code>gcm-client</code>, <code>gcm-server</code>,
-<code>samples/gcm-demo-client</code>, <code>samples/gcm-demo-server</code>,
-and <code>samples/gcm-demo-appengine</code>.</p>
-
-<p class="note"><strong>Note:</strong> If you don't see <strong>Extras &gt; Google Cloud Messaging for Android Library</strong> in the SDK Manager, make sure you are running version 20 or higher. Be sure to restart the SDK Manager after updating it.</p>
-
-<h2 id="android-app">Writing the Android Application</h2>
-<p>This section describes the steps involved in writing an Android application that uses GCM.</p>
-<h4>Step 1: Copy the gcm.jar file into your application classpath</h4>
-<p> To write your Android application, first copy the <code>gcm.jar</code> file from the SDK's <code>gcm-client/dist</code> directory to your application classpath.</p>
-<h4>Step 2: Make the following changes in the application's Android manifest</h4>
-<ol>
-  <li>GCM requires Android 2.2 or later, so if your application cannot work without GCM, add the following line, where <em>xx</em> is the latest target SDK version:</li>
-
-<pre class="prettyprint pretty-xml">&lt;uses-sdk android:minSdkVersion=&quot;8&quot; android:targetSdkVersion=&quot;xx&quot;/&gt;</pre>
-
-  <li>Declare and use a custom permission so only this application can receive GCM messages:<br>
-  </li>
-
-<pre class="prettyprint pretty-xml">&lt;permission android:name=&quot;my_app_package.permission.C2D_MESSAGE&quot; android:protectionLevel=&quot;signature&quot; /&gt;
-&lt;uses-permission android:name=&quot;my_app_package.permission.C2D_MESSAGE&quot; /&gt; </pre>
-<p> This permission must be called <code>my_app_package.permission.C2D_MESSAGE</code> (where <code>my_app_package</code> is the package name of your app as defined by the manifest tag), otherwise it will not  work.</p>
-<p class="note"><strong>Note:</strong> This permission is not required if you are targeting your application to 4.1 or above (i.e., minSdkVersion 16)</p>
-
-  <li>Add the following permissions:</li>
-
-<pre class="prettyprint pretty-xml">&lt;!-- App receives GCM messages. --&gt;
-&lt;uses-permission android:name=&quot;com.google.android.c2dm.permission.RECEIVE&quot; /&gt;
-&lt;!-- GCM connects to Google Services. --&gt;
-&lt;uses-permission android:name=&quot;android.permission.INTERNET&quot; /&gt; 
-&lt;!-- GCM requires a Google account. --&gt;
-&lt;uses-permission android:name=&quot;android.permission.GET_ACCOUNTS&quot; /&gt;
-&lt;!-- Keeps the processor from sleeping when a message is received. --&gt;
-&lt;uses-permission android:name=&quot;android.permission.WAKE_LOCK&quot; /&gt;</pre>
-
-  <li>Add the following broadcast receiver:</li>
-
-<pre class="prettyprint pretty-xml">&lt;receiver android:name=&quot;com.google.android.gcm.GCMBroadcastReceiver&quot; android:permission=&quot;com.google.android.c2dm.permission.SEND&quot; &gt;
-  &lt;intent-filter&gt;
-    &lt;action android:name=&quot;com.google.android.c2dm.intent.RECEIVE&quot; /&gt;
-    &lt;action android:name=&quot;com.google.android.c2dm.intent.REGISTRATION&quot; /&gt;
-    &lt;category android:name=&quot;my_app_package&quot; /&gt;
-  &lt;/intent-filter&gt;
-&lt;/receiver&gt;</pre>
-<p> This broadcast receiver is responsible for handling the 2 intents that can be sent by GCM (<code>com.google.android.c2dm.intent.RECEIVE</code> and <code>com.google.android.c2dm.intent.REGISTRATION</code>) and should be defined in the manifest (rather than programmatically) so that these intents can be received even if the application is not running. By setting the <code>com.google.android.c2dm.permission.SEND</code> permission, you are ensuring that only intents sent by the GCM system framework are sent to the receiver (a regular application cannot issue intents with that permission).</p>
-<p> Notice that <code>android:name</code> in the category tag must be replaced by your application's package name (and the category tag  is not required for applications targeted to minSdkVersion 16 and higher).<br>
-  </p>
-
-  <li>Add the following intent service:</li>
-
-
- <pre class="prettyprint pretty-xml">&lt;service android:name=&quot;.GCMIntentService&quot; /&gt;</pre>
-
-</ol>
-<p>This intent service will be called by the <code>GCMBroadcastReceiver</code> (which is provided by the GCM library), as shown in the next step. It must be a subclass of <code>com.google.android.gcm.GCMBaseIntentService</code>, must contain a public constructor, and should be named <code>my_app_package.GCMIntentService</code> (unless you use a subclass of <code>GCMBroadcastReceiver</code> that overrides the method used to name the service).</p>
-
-<p>The intent service must also define its sender ID(s). It does this as follows:</p>
-<ul>
-  <li>If the value is static, the service's default constructor should call <code>super(senderIds)</code>.</li>
-  <li>If the value is dynamic, the service should override the <code>getSenderIds()</code> method.</li>
-</ul>
-
-
-<h4>Step 3: Write the my_app_package.GCMIntentService class</h4>
-
-<p>Next write the <code>my_app_package.GCMIntentService</code> class, overriding the following callback methods (which are called by <code>GCMBroadcastReceiver</code>):<br>
-</p>
-<ul>
-  <li><code>onRegistered(Context context, String regId)</code>: Called after a registration intent is received, passes the registration ID assigned by GCM to that device/application pair as parameter. Typically, you should send the <code>regid</code> to your server so it can use it to send messages to this device.</li>
-  <li><code>onUnregistered(Context context, String regId)</code>: Called after the device has been unregistered from GCM. Typically, you should send the <code>regid</code> to the server so it unregisters the device.</li>
-  <li><code>onMessage(Context context, Intent intent)</code>: Called when your server sends a message to GCM, and GCM delivers it to the device. If the message has a payload, its contents are available as extras in the intent.</li>
-  <li><code>onError(Context context, String errorId)</code>: Called when the device tries to register or unregister, but GCM returned an error. Typically, there is nothing to be done other than evaluating the error (returned by errorId) and trying to fix the problem.</li>
-  <li> <code>onRecoverableError(Context context, String errorId)</code>: Called when the device tries to register or unregister, but the GCM servers are unavailable. The GCM library will retry the operation using exponential backup, unless this method is overridden and returns false. This method is optional and should be overridden only if you want to display the message to the user or cancel the retry attempts. 
-  </li>
-</ul>
-
-<p class="note"><strong>Note:</strong> The methods above run in the intent service's thread and hence are free to make network calls without the risk of blocking the UI thread.</p>
-
-<h4> Step 4: Write your application's main activity</h4>
-Add the following import statement in your application's main activity:
-<pre class="prettyprint pretty-java">import com.google.android.gcm.GCMRegistrar;</pre>
-<p> In the <code>onCreate()</code> method, add the following code:</p>
-<pre class="prettyprint pretty-java">GCMRegistrar.checkDevice(this);
-GCMRegistrar.checkManifest(this);
-final String regId = GCMRegistrar.getRegistrationId(this);
-if (regId.equals("")) {
-  GCMRegistrar.register(this, SENDER_ID);
-} else {
-  Log.v(TAG, "Already registered");
-}</pre>
-<p>The <code>checkDevice()</code> method verifies that the device supports GCM and throws an exception if it does not (for instance, if it is an emulator that does not contain the Google APIs). Similarly, the <code>checkManifest()</code> method verifies that the application manifest contains meets all the requirements described in <a href="#android-app">Writing the Android Application</a> (this method is only necessary when you are developing the application; once the application is ready to be published, you can remove it).</p>
-
-<p>Once the sanity checks are done, the device calls <code>GCMRegsistrar.register()</code> to register the device, passing the <code>SENDER_ID</code> you got when you signed up for GCM. But since the <code>GCMRegistrar</code> singleton keeps track of the registration ID upon the arrival of registration intents, you can call <code>GCMRegistrar.getRegistrationId()</code> first to check if the device is already registered.</p>
-<p class="note"><strong>Note:</strong> It is possible that the device was successfully registered to GCM but failed to send the registration ID to your server, in which case you should retry. See <a href="adv.html#reg-state">Advanced Topics</a> for more details on how to handle this scenario.</p>

-<p>To write the server-side application:</p>
-<ol>
-  <li> Copy the <code>gcm-server.jar</code> file from the SDK's <code>gcm-server/dist</code> directory to your server classpath.</li>
-  <li>Create a servlet (or other server-side mechanism) that can be used by the Android application to send the registration ID received by GCM . The application might also need to send other information&mdash;such as the user's email address or username&mdash;so that the server can associate the registration ID with the user owning the device.</li>
-  <li>Similarly, create a servlet used to unregister registration IDs.<br>
-    </li>
-<li>When the server needs to send a message to the registration ID, it can use the <code>com.google.android.gcm.server.Sender</code> helper class from the GCM library. For example:</li>
-</ol>
-
-<pre class="prettyprint pretty-java">import com.google.android.gcm.server.*;
-
-Sender sender = new Sender(myApiKey);
-Message message = new Message.Builder().build();
-MulticastResult result = sender.send(message, devices, 5);</pre>
-
-<p> The snippet above does the following:
-<ul>
-<li>Creates a <code>Sender</code> object using your project's API key.</li>
-<li>Creates a message using a given registration ID (the message builder also has methods to set all message parameters such as the collapse key and payload data).</li>
-<li>Sends the message with a maximum of 5 retry attempts (in case the GCM servers are unavailable), and stores the response on result. </li>
-</ul>
-<p>It's now necessary to parse the result and take the proper action in the following cases:</p>
-<ul>
-  <li>If the message was created but the result returned a canonical registration ID, it's necessary to replace the current registration ID with the canonical one.</li>
-  <li>If the returned error is <code>NotRegistered</code>, it's necessary to remove that registration ID, because the application was uninstalled from the device.</li>
-</ul>
-<p> Here's a code snippet that handles these 2 conditions:</p>
-<pre class="prettyprint pretty-java">
-if (result.getMessageId() != null) {
- String canonicalRegId = result.getCanonicalRegistrationId();
- if (canonicalRegId != null) {
-   // same device has more than on registration ID: update database
- }
-} else {
- String error = result.getErrorCodeName();
- if (error.equals(Constants.ERROR_NOT_REGISTERED)) {
-   // application has been removed from device - unregister database
- }
-}</pre>

-
-<p>This document describes the Google Cloud Messaging (GCM) HTTP
-connection server. Connection servers
-are the Google-provided servers that take messages from the 3rd-party
-application server and sending them to the device.</p>
-
-<p class="note"><strong>Note:</strong> The content in this document
-applies to <a href="http://developer.chrome.com/apps/cloudMessaging">
-GCM with Chrome apps</a> as well as Android.</p>
-
-<p>See the
-<a href="server-ref.html">Server Reference</a> for a list of all the message
-parameters and which connection server(s) supports them.</p>
-
-
-<h2 id="auth">Authentication</h2>
-
-<p>To send a  message, the application server issues a POST request. For example:</p>
-<pre>https://android.googleapis.com/gcm/send</pre>
-<p>A  message request is made of 2 parts: HTTP header and HTTP body.</p>
-
-<p>The HTTP header must contain the following headers:</p>
-<ul>
-  <li><code>Authorization</code>: key=YOUR_API_KEY</li>
-  <li><code>Content-Type</code>: <code>application/json</code> for JSON;
-<code>application/x-www-form-urlencoded;charset=UTF-8</code> for plain text.
-If <code>Content-Type</code> is omitted, the format
-is assumed to be plain text.
-  </li>
-</ul>
-
-<p>For example:
-</p>
-
-<pre>Content-Type:application/json
-Authorization:key=AIzaSyB-1uEai2WiUapxCs2Q0GZYzPu7Udno5aA
-
-{
-  "registration_ids" : ["APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx..."],
-  "data" : {
-    ...
-  },
-}</pre>
-
-
-<p>The HTTP body content depends on whether you're using JSON or plain text.
-See
-<a href="server-ref.html#params">the Server Reference</a> for a list of all the
-parameters your JSON or plain text message can contain.</p>
-
-<h3 id="checkAPIkey">Checking the validity of an API key</h3>
-
-<p>If you receive authentication errors when sending messages, check the validity
-of your API key. For example, on Android, run the following command:</p>
-
-<pre># api_key=YOUR_API_KEY
-
-# curl --header "Authorization: key=$api_key" \
-       --header Content-Type:"application/json" \
-       https://android.googleapis.com/gcm/send \
-       -d "{\"registration_ids\":[\"ABC\"]}"</pre>
-
-<p>
-If you receive a 401 HTTP status code, your API key is not valid. Otherwise you
-should see something like this:</p>
-
-<pre>
-{"multicast_id":6782339717028231855,"success":0,"failure":1,
-"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}
-</pre>
-
-<p>
-If you want to confirm the validity of a registration ID, you can do so by
-replacing "ABC" with the registration ID.
-</p>
-
-
-  <h2 id="request">Request Format</h2>
-
-<p>This section shows you how to format a request for both JSON and plain text. See
-the <a href="server-ref.html#table1">Server Reference</a> for a complete
-list of the fields you can include in a request.</p>
-
-  <p>Here is the smallest possible request (a message without any parameters and
-just one recipient) using JSON:</p>
-
-  <pre class="prettyprint pretty-json">{ &quot;registration_ids&quot;: [ &quot;42&quot; ] }</pre>
-
-  <p>And here the same example using plain text:</p>
-  <pre class="prettyprint">registration_id=42</pre>
-
-  <p> Here is a message with a payload and 6 recipients:</p>
-
-  <pre class="prettyprint pretty-HTML">{ "data": {
-    "score": "5x1",
-    "time": "15:10"
-  },
-  "registration_ids": ["4", "8", "15", "16", "23", "42"]
-}</pre>
-  <p>Here is a message with all optional fields set and 6 recipients:</p>
-  <pre class="prettyprint pretty-json">{ "collapse_key": "score_update",
-  "time_to_live": 108,
-  "delay_while_idle": true,
-  "data": {
-    "score": "4x8",
-    "time": "15:16.2342"
-  },
-  "registration_ids":["4", "8", "15", "16", "23", "42"]
-}</pre>
-  <p>And here is the same message using plain-text format (but just 1 recipient):  </p>
-
-  <pre class="prettyprint">collapse_key=score_update&amp;time_to_live=108&amp;delay_while_idle=1&amp;data.score=4x8&amp;data.time=15:16.2342&amp;registration_id=42
-  </pre>
-
-<p>Here is a message that includes a notification key and payload:</p>
-
-<pre>
-{
-  "data": {
-    "message": "ciao"
-  },
-  "notification_key":"aUniqueKey"
-}
-</pre>
-
-<p>For more information about notifications and how to use them, see
-<a href="{@docRoot}google/gcm/notifications.html">User Notifications</a>.</p>
-
-
-<p class="note"><strong>Note:</strong> If your organization has a firewall
-that restricts the traffic to or
-from the Internet, you need to configure it to allow connectivity with GCM in order for
-your GCM client apps to receive messages.
-The ports to open are: 5228, 5229, and 5230. GCM typically only uses 5228, but
-it sometimes uses 5229 and 5230. GCM doesn't provide specific IPs, so you should allow
-your firewall to accept outgoing connections to all IP addresses
-contained in the IP blocks listed in Google's ASN of 15169.</p>
-
-
-
-<h2 id="response">Response format</h2>
-
-<p>There are two possible outcomes when trying to send a message:</p>
-<ul>
-  <li>The message is processed successfully. The HTTP response has a 200 status, and
-the body contains more information about the status of the message (including possible errors).</li>
-  <li>The GCM server rejects the request. The HTTP response contains a
-non-200 status code (such as 400, 401 or 5xx).</li>
-</ul>
-
-<p>When a JSON request is successful (HTTP status code 200), the JSON object returned
-contains the <a href="{@docRoot}google/gcm/server-ref.html#table4">
-Downstream HTTP message response body</a>.</p>
-
-<p>If the value of <code>failure</code> and <code>canonical_ids</code> is 0, it's
-not necessary to parse the remainder of the response. Otherwise, we recommend
-that you iterate through the results field and do the following for each object
-in that list:</p>
-<ul>
-  <li>If <code>message_id</code> is set, check for <code>registration_id</code>:
-    <ul>
-      <li>If <code>registration_id</code> is set, replace the original ID with
-the new value (canonical ID) in your server database. Note that the original ID
-is not part of the result, so you need to obtain it from the list of
-code>registration_ids</code> passed in the request (using the same index).</li>
-    </ul>
-  </li>
-  <li>Otherwise, get the value of <code>error</code>:
-    <ul>
-      <li>If it is <code>Unavailable</code>, you could retry to send it in another
-request.</li>
-      <li>If it is <code>NotRegistered</code>, you should remove the registration
-ID from your server database because the application was uninstalled from the
-device, or the client app isn't configured to receive
-messages.</li>
-      <li>Otherwise, there is something wrong in the registration ID passed in
-the request; it is probably a non-recoverable error that will also require removing
-the registration from the server database. See
-<a href="{@docRoot}google/gcm/server-ref.html#error-codes">Downstream message error response
-  codes</a> for all possible error values.</li>
-    </ul>
-  </li>
-</ul>
-
-<p>When a plain-text request is successful (HTTP status code 200), the response
-body contains 1 or 2 lines in the form of key/value pairs.
-The first line is always available and its content is either <code>id=<em>ID of
-sent message</em></code> or <code>Error=<em>GCM error code</em></code>. The second
-line, if available,
-has the format of <code>registration_id=<em>canonical ID</em></code>. The second
-line is optional, and it can only be sent if the first line is not an error. We
-recommend handling the plain-text response in a similar way as handling the
-JSON response:</p>
-<ul>
-  <li>If first line starts with <code>id</code>, check second line:
-    <ul>
-      <li>If second line starts with <code>registration_id</code>, gets its value
-and replace the registration IDs in your server database.</li>
-    </ul>
-  </li>
-  <li>Otherwise, get the value of <code>Error</code>:
-    <ul>
-      <li>If it is <code>NotRegistered</code>, remove the registration ID from
-your server database.</li>
-      <li>Otherwise, there is probably a non-recoverable error (<strong>Note:
-</strong>Plain-text requests will never return <code>Unavailable</code> as the
-error code, they would have returned a 500 HTTP status instead).</li>
-    </ul>
-  </li>
-</ul>
-
-
-<h3 id="example-responses">Example responses</h3>
-<p>This section shows a few examples of responses indicating messages that were
-processed successfully. See <a href="#request">Request Format</a> for
-the requests these responses are based on.</p>
-<p> Here is a simple case of a JSON message successfully sent to one recipient
-without canonical IDs in the response:</p>
-<pre class="prettyprint pretty-json">{ "multicast_id": 108,
-  "success": 1,
-  "failure": 0,
-  "canonical_ids": 0,
-  "results": [
-    { "message_id": "1:08" }
-  ]
-}</pre>
-
-<p>Or if the request was in plain-text format:</p>
-<pre class="prettyprint">id=1:08
-</pre>
-
-<p>Here are JSON results for 6 recipients (IDs 4, 8, 15, 16, 23, and 42 respectively)
-with 3 messages successfully processed, 1 canonical registration ID returned,
-and 3 errors:</p>
-<pre class="prettyprint pretty-json">{ "multicast_id": 216,
-  "success": 3,
-  "failure": 3,
-  "canonical_ids": 1,
-  "results": [
-    { "message_id": "1:0408" },
-    { "error": "Unavailable" },
-    { "error": "InvalidRegistration" },
-    { "message_id": "1:1516" },
-    { "message_id": "1:2342", "registration_id": "32" },
-    { "error": "NotRegistered"}
-  ]
-}
-</pre>
-<p> In this example:</p>
-<ul>
-  <li>First message: success, not required.</li>
-  <li>Second message: should be resent (to registration ID 8).</li>
-  <li>Third message: had an unrecoverable error (maybe the value got corrupted
-in the database).</li>
-  <li>Fourth message: success, nothing required.</li>
-  <li>Fifth message: success, but the registration ID should be updated in the
-server database (from 23 to 32).</li>
-  <li>Sixth message: registration ID (42) should be removed from the server database
-because the application was uninstalled from the device.</li>
-</ul>
-<p>Or if just the 4th message above was sent using plain-text format:</p>
-<pre class="prettyprint">Error=InvalidRegistration
-</pre>
-<p>If the 5th message above was also sent using plain-text format:</p>
-<pre class="prettyprint">id=1:2342
-registration_id=32
-</pre>
-
-
-<h2 id="app-server">Implementing an HTTP-Based App Server</h2>
-
-<p>This section gives examples of implementing an app server that works with the
-GCM HTTP connection server. Note that a full GCM implementation requires a
-client-side implementation, in addition to the server. This example is based on Android.</a>
-
-
-<p>Requirements</p>
-<p>For the web server:</p>
-<ul>
-  <li> <a href="http://ant.apache.org/">Ant 1.8</a> (it might work with earlier versions, but it's not guaranteed).</li>
-  <li>One of the following:
-    <ul>
-      <li>A running web server compatible with Servlets API version 2.5, such as
-<a href="http://tomcat.apache.org/">Tomcat 6</a> or <a href="http://jetty.codehaus.org/">Jetty</a>, or</li>
-      <li><a href="http://code.google.com/appengine/">Java App Engine SDK</a>
-version 1.6 or later.</li>
-    </ul>
-  </li>
-  <li>A Google account registered to use GCM.</li>
-  <li>The API  key for that account.</li>
-</ul>
-<p>For the Android application:</p>
-<ul>
-  <li>Emulator (or device) running Android 2.2 (ideally, 2.3 or above) with Google APIs.</li>
-  <li>The Google API project number of the account registered to use GCM.</li>
-</ul>
-
-<h3 id="gcm-setup">Setting Up GCM</h3>
-<p>Before proceeding with the server and client setup, it's necessary to register
-a Google account with the Google API Console, enable Google Cloud Messaging in GCM,
-and obtain an API key from the <a href="https://code.google.com/apis/console">
-Google API Console</a>.</p>
-<p>For instructions on how to set up GCM, see <a href="gs.html">Getting Started</a>.</p>
-
-
-<h3 id="server-setup">Setting Up an HTTP Server</h3>
-<p>This section describes the different options for setting up an HTTP server.</p>
-
-<h4 id="webserver-setup">Using a standard web server</h4>
-<p>To set up the server using a standard, servlet-compliant web server:</p>
-<ol>
-  <li>From the <a href="http://code.google.com/p/gcm">open source site</a>,
-download the following directories: <code>gcm-server</code>,
-<code>samples/gcm-demo-server</code>, and <code>samples/gcm-demo-appengine</code>.</p>
-
-
-  <li>In a text editor, edit the <code>samples/gcm-demo-server/WebContent/WEB-INF/classes/api.key</code> and replace the existing text with the API key obtained above.</li>
-  <li>In a shell window, go to the <code>samples/gcm-demo-server</code> directory.</li>
-  <li>Generate the server's WAR file by running <code>ant war</code>:</li>
-
-  <pre class="prettyprint">$ ant war
-
-Buildfile:build.xml
-
-init:
-   [mkdir] Created dir: build/classes
-   [mkdir] Created dir: dist
-
-compile:
-   [javac] Compiling 6 source files to build/classes
-
-war:
-     [war] Building war: <strong>dist/gcm-demo.war</strong>
-
-BUILD SUCCESSFUL
-Total time: 0 seconds
-</pre>
-
-  <li>Deploy the <code>dist/gcm-demo.war</code> to your running server. For instance, if you're using Jetty, copy <code>gcm-demo.war</code> to the <code>webapps</code> directory of the Jetty installation.</li>
-  <li>Open the server's main page in a browser. The URL depends on the server you're using and your machine's IP address, but it will be something like <code>http://192.168.1.10:8080/gcm-demo/home</code>, where <code>gcm-demo</code> is the application context and <code>/home</code> is the path of the main servlet.
-
-  </li>
-</ol>
-<p class="note"><strong>Note:</strong> You can get the IP by running <code>ifconfig</code> on Linux or MacOS, or <code>ipconfig</code> on Windows. </p>
-
-<p> You server is now ready.</p>
-
-<h4 id="appengine-setup">Using App Engine for Java</h4>
-
-<p>To set up the server using a standard App Engine for Java:</p>
-<ol>
-  <li>Get the files from the <a href="http://code.google.com/p/gcm">open source
-site</a>, as described above.</p>
-  </li>
-  <li>In a text editor, edit
-<code>samples/gcm-demo-appengine/src/com/google/android/gcm/demo/server/ApiKeyInitializer.java</code>
-and replace the existing text with the API key obtained above.
-
-  <p class="note"><strong>Note:</strong> The API key value set in that class will
-be used just once to create a persistent entity on App Engine. If you deploy
-the application, you can use App Engine's <code>Datastore Viewer</code> to change
-it later.</p>
-
-  </li>
-  <li>In a shell window, go to the <code>samples/gcm-demo-appengine</code> directory.</li>
-  <li>Start the development App Engine server by <code>ant runserver</code>,
-using the <code>-Dsdk.dir</code> to indicate the location of the App Engine SDK
-and <code>-Dserver.host</code> to set your server's hostname or IP address:</li>
-
-<pre class="prettyprint">

-  Google Cloud Messaging (GCM) for Android is a service that allows you to send data
-from your server to your users' Android-powered device, and also to receive messages from
-devices on the same connection. The GCM service handles all aspects of queueing of messages
-and delivery to the target Android application running on the target device, and it is

-    <h4>Send data from your server to users' Android-powered devices</h4>
-    <p>This could be a lightweight
-message telling your app there is new data to be fetched from the
-server (for instance, a movie uploaded by a friend), or it could be a message containing
-up to 4kb of payload data (so apps like instant messaging can consume the message directly).
-<a href="{@docRoot}google/gcm/gcm.html">GCM Architectural Overview.</a></p>
-
-    <h4>Send "send-to-sync" messages</h4>
-    <p>A send-to-sync (collapsible) message is often a "tickle" that tells a mobile
-    application to sync data from the server. For example, suppose you have an email
-    application. When a user receives new email on the server, the server pings the mobile
-    application with a "New mail" message. This tells the application to sync to the server
-    to pick up the new email.
-    <a href="{@docRoot}google/gcm/adv.html#s2s">Learn more &raquo;</a></p>
-
-    <h4>Send messages with payload</h4>

-<p>With user notifications, 3rd-party app servers can send a single message to
-multiple instance of an app running on devices owned by a single user. This feature
-is called <em>user notifications</em>. User notifications make it possible for every
-app instance that a user owns to reflect the latest messaging state. For example:</p>
-
-  <ul>
-  <li>If a message has been handled on one device, the GCM message on the other
-devices are dismissed. For example, if a user has handled a calendar notification
-on one device, the notification will go away on the user's other devices.</li>
-
-  <li>If a message has not been delivered yet to a device and but it has been handled,
-the GCM server removes it from the unsent queue for the other devices.</li>
-
-  <li>Likewise, a device can send messages to the {@code notification_key}, which
-is the token that GCM uses to fan out notifications to all devices whose
-registration IDs are associated with the key.</li>
-</ul>
-
-<p>The way this works is that during registration, the 3rd-party server requests
-a {@code notification_key}. The {@code notification_key} maps a particular user
-to all of the user's associated registration IDs (a regID represents a particular
-Android application running on a particular device). Then instead of sending one
-message to one regID at a time, the 3rd-party server can send a message to to the
-{@code notification_key}, which then sends the message to all of the user's regIDs.</p>
-
-<p class="note"><strong>Note:</strong> A notification dismissal message is like any
-other upstream message, meaning that it will be delivered to the other devices that
-belong to the specified {@code notification_key}. You should design your app to
-handle cases where the app receives a dismissal message, but has not yet displayed
-the notification that is being dismissed. You can solve this by caching the dismissal
-and then reconciling it with the corresponding notification.
-</p>
-
-<p>You can use this feature with either the <a href="ccs.html">XMPP</a> (CCS) or
-<a href="http.html">HTTP</a> connection server.</p>
-
-<p>You can generate notification keys in two different ways: on the server, and on
-the client, if the user has a Google account. All of the associated registration IDs
-can be mapped to a single user.</p>
-
-<p>The examples below show you how to perform generate/add/remove operations,
-and how to send upstream messages. For generate/add/remove operations, the
-message body is JSON.</p>
-
-<h2 id="gen-server">Generate a Notification Key on the Server</h2>
-
-<p>To generate a notification key on the server, you create a new
-<code>notification_key</code> and map it to a
-<code>notification_key_name</code>.</p>
-
-<p>This example shows how to create a new <code>notification_key</code> for a
-<code>notification_key_name</code> called <code>appUser-Chris</code>.
-The {@code notification_key_name} is a name or identifier (it can be a username for
-a 3rd-party app) that is unique to a given user. It is used by third parties to
-group together registration IDs for a single user. Note that <code>notification_key_name</code>
-and <code>notification_key</code> are unique to a group of registration IDs. It is also
-important that <code>notification_key_name</code> be uniquely named per app in case
-you have multiple apps for the same project ID. This ensures that notifications
-only go to the intended target app.</p>
-
-
-<p>A create operation returns a token (<code>notification_key</code>). Third parties
-must save this token (as well as its mapping to the <code>notification_key_name</code>)
-to use in subsequent operations:</p>
-
-<pre>request:
-{ 
-   &quot;operation&quot;: &quot;create&quot;,
-   &quot;notification_key_name&quot;: &quot;appUser-Chris&quot;,
-   &quot;registration_ids&quot;: [&quot;4&quot;, &quot;8&quot;, &quot;15&quot;, &quot;16&quot;, &quot;23&quot;, &quot;42&quot;]
-}</pre>
-
-<h3 id="request-server">Request format</h3>
-
-<p>To send a message in cases where your notification key is generated on the server,
-the application server issues a POST request to
-<code>https://android.googleapis.com/gcm/notification</code>.</p>
-
-<p>Here is the HTTP request header you should use for all server side create/add/remove operations:</p>
-
-<pre>content-type: "application/json"
-Header : "project_id": &lt;projectID&gt;
-Header: "Authorization", "key=API_KEY"
-</pre>
-
-
-<h2 id="gen-client">Generate a Notification Key on the Client</h2>
-
-<p>Generating a notification key on the client is useful for cases where a server is unavailable.
-To generate a notification key on the client, the device must have at least one
-Google account. Note that the process for generating a notification key on the client is significantly
-different from the server process described above.</p>
-
-<p>To generate a notification key on the client:</p>
-
-<ol>
-  <li>Open your project in the <a href="https://cloud.google.com/console">Google Developers Console</a>.</li>
-  <li>Click <strong>APIS &amp; AUTH &gt; Credentials</strong>.</li>
-  <li>Under OAuth, click <strong>Create new Client ID</strong>.</li>
-  <li>In the <strong>Create Client ID</strong> dialog, select <strong>Web Application</strong> as
-the application type, and click <strong>Create Client ID</strong>.</li>
-  <li>Copy the value from <strong>Client ID for web application &gt; Client ID</strong>.
-This client ID represents a Google account "scope" that you will use to generate an {@code id_token}.</li>
-</ol>
-
-<p>Once you've followed the above steps and gotten a client ID from Google Developers Console,
- you're ready to add this feature to your app. First check the device for the presence of a Google
-account. For example:</p>
-
-<pre>// This snippet takes the simple approach of using the first returned Google account,
-// but you can pick any Google account on the device.
-public String getAccount() {
-    Account[] accounts = AccountManager.get(getActivity()).
-        getAccountsByType(&quot;com.google&quot;);
-    if (accounts.length == 0) {
-        return null;
-    }
-    return accounts[0].name;
-}</pre>
-
-<p>Next, get an authentication token ({@code id_token}) by using the <code><a href=
-"http://developer.android.com/reference/com/google/android/gms/auth/GoogleAuthUtil.html">GoogleAuthUtil</a></code>
-class. For example:</p>
-
-<pre>String accountName = getAccount();
-
-// Initialize the scope using the client ID you got from the Console.
-final String scope = &quot;audience:server:client_id:&quot;
-        + &quot;1262xxx48712-9qs6n32447mcj9dirtnkyrejt82saa52.apps.googleusercontent.com&quot;;
-String id_token = null;
-try {
-    id_token = GoogleAuthUtil.getToken(context, accountName, scope);
-} catch (Exception e) {
-    log(&quot;exception while getting id_token: &quot; + e);
-}
-...</pre>
-
-<p>Now use <code>id_token</code> to authenticate your request.
-This add operation returns a {@code notification_key}.
-Third parties must save this {@code notification_key} (as well as its mapping to the
-<code>notification_key_name</code>)
-to use in subsequent operations. Note that a client request only takes a single regID.
-The only operations supported on the client side are add/remove.</p>
-
-<pre>request:
-{
-   &quot;operation&quot;: &quot;add&quot;,
-   &quot;notification_key_name&quot;: &quot;appUser-Chris&quot;,
-   &quot;registration_ids&quot;: [&quot;4&quot;]
-   &quot;id_token&quot;: &quot;id_token&quot;
-}</pre>
-
-<h3 id="request-client">Request format</h3>
-
-<p>To send a message in cases where your notification key is generated on the client,
-the application server issues a POST request to
-<code>https://android.googleapis.com/gcm/googlenotification</code>.</p>
-
-<p>Here is the HTTP request header you should use for all add/remove operations. The
-client side doesn't support the create operation;
-the add operation has the effect of creating the notification key if it doesn't already
-exist:</p>
-
-<pre>content-type: "application/json"
-Header : "project_id": &lt;projectID&gt;
-</pre>
-
-<p>Note that the authentication token is passed in the JSON body as shown above, not the header.
-This is different from the server case.</p>
-
-
-<h2 id="add">Add Registration IDs</h2>
-
-<p>This example shows how to add registration IDs for a given notification key.
-The maximum number of members allowed for a {@code notification_key} is 20.</p>
-
-<p>Note that the <code>notification_key_name</code> is not strictly required for
-adding/removing regIDs. But including it protects you against accidentally using
-the incorrect <code>notification_key</code>.</p>
-
-<pre>request:
-{ 
-   &quot;operation&quot;: &quot;add&quot;,
-   &quot;notification_key_name&quot;: &quot;appUser-Chris&quot;,
-   &quot;notification_key&quot;: &quot;aUniqueKey&quot;
-   &quot;registration_ids&quot;: [&quot;4&quot;, &quot;8&quot;, &quot;15&quot;, &quot;16&quot;, &quot;23&quot;, &quot;42&quot;]
-}</pre>
-
-<h2 id="remove">Remove Registration IDs</h2>
-
-<p>This example shows how to remove registration IDs for a given notification key:</p>
-<pre>request:
-{ 
-   &quot;operation&quot;: &quot;remove&quot;,
-   &quot;notification_key_name&quot;: &quot;appUser-Chris&quot;,
-   &quot;notification_key&quot;: &quot;aUniqueKey&quot;
-   &quot;registration_ids&quot;: [&quot;4&quot;, &quot;8&quot;, &quot;15&quot;, &quot;16&quot;, &quot;23&quot;, &quot;42&quot;]
-}</pre>
-
-<h2 id="upstream">Send Upstream Messages</h2>
-
-<p>To send an upstream (device-to-cloud) message, you must use the
-<a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">
-{@code GoogleCloudMessaging}</a> API. Specifying a {@code notification_key} as the target
-for an upstream message allows a user on one device to send a message to other
-devices in the notification group&mdash;for example, to dismiss a notification.
-Here is an example that shows targeting a {@code notification_key}:</p>
-
-<pre>GoogleCloudMessaging gcm = GoogleCloudMessaging.get(context);
-String to = NOTIFICATION_KEY;
-AtomicInteger msgId = new AtomicInteger();
-String id = Integer.toString(msgId.incrementAndGet());
-Bundle data = new Bundle();
-data.putString("hello", "world");
-
-gcm.send(to, id, data);
-</pre>
-
-<p>This call generates the necessary XMPP stanza for sending the message. The
-Bundle data consists of a key-value pair.</p>
-
-<p>For a complete example, see <a href="client.html">Implementing GCM Client</a>.
-
-<h2 id="response">Response Formats</h2>
-
-<p>This section shows examples of the responses that can be returned for
-notification key operations.</p>
-
-<h3 id="response-create">Create/add/remove operations</h3>
-
-<p>When you make a request to create a {@code notification_key} or to add/remove its
-regIDs, a successful response always returns the <code>notification_key</code>.
-Use the returned {@code notification_key} for sending messages:</p>
-
-<pre>HTTP status: 200
-{ 
-    &quot;notification_key&quot;: &quot;aUniqueKey&quot;,   // to be used for sending
-}</pre>
-
-
-<h3 id="response-send">Send operations</h3>
-
-<p>For a send operation that has a {@code notification_key} as its target, the
-possible responses are success, partial success, and failure.</p>
-
-<p>Here is an example of "success"&mdash;the {@code notification_key} has 2 regIDs
-associated with it, and the message was successfully sent to both of them:</p>
-
-<pre>{
-  "success": 2,
-  "failure": 0
-}</pre>
-
-<p>Here is an example of "partial success"&mdash;the {@code notification_key} has
-3 regIDs associated with it. The message was successfully send to 1 of the regIDs,
-but not to the other 2. The response message lists the regIDs that failed to
-receive the message:</p>
-
-<pre>{
-  "success":1,
-  "failure":2,
-  "failed_registration_ids":[
-     "regId1",
-     "regId2"
-  ]
-}</pre>
-
-<p>In the case of failure, the response has HTTP code 503 and no JSON. When a message
-fails to be delivered to one or more of the regIDs associated with a {@code notification_key},
-the 3rd-party server should retry.</p>

-
-<h2 id="downstream">Downstream Messages</h2>
-<p>This is the message that a 3rd-party app server sends to a client app.
-</p>
-<p>A downstream message includes the following components:</p>
-<ul>
-  <li>Target: specifies the recipient of the message.</li>
-  <li>Options: specifies attributes of the message.</li>
-  <li>Payload: specifies additional content to be included in the message. Optional.</li>

-</ul>
-</p>
-
-<p>A full GCM implementation requires both a client implementation and a server
-implementation. For more
-information about implementing the client side, see <a href="client.html">
-Implementing GCM Client</a>.</p>
-
-
-<h2 id="role">Role of the 3rd-party Application Server</h2>
-
-<p>Before you can write client apps that use the GCM feature, you must
-have an  application server that meets the following criteria:</p>
-
-<ul>
-  <li>Able to communicate with your client.</li>
-  <li>Able to  fire off properly formatted requests to the GCM server.</li>
-  <li>Able to handle requests and resend them as needed, using
-<a href="http://en.wikipedia.org/wiki/Exponential_backoff">exponential back-off.</a></li>
-  <li>Able to store the API key and client registration IDs. In HTTP, the API key is
-included in the header of POST requests that send messages. In XMPP, the API key is
-used in the SASL PLAIN authentication request as a password to authenticate the connection.</li>
- <li>Able to generate message IDs to uniquely identify each message it sends. Message IDs
-should be unique per sender ID.</li>
-</ul>
-
-<p>Here are the basic steps you follow to implement your 3rd-party app server:</p>
-
-<ul>
-      <li>Decide which GCM connection server(s) you want to use. Note that if you want to use
-      upstream messaging from your client applications, you must use XMPP (CCS). For a more detailed
-      discussion of this, see <a href="#choose">
-      Choosing a GCM Connection Server</a>.</li>
-      <li>Decide how you want to implement your app server. We provide helper libraries and code
-samples to assist you with your 3rd-party app server implementation. For example:
-        <ul>
-          <li>If you decide to use the HTTP connection server, you can use the
-GCM server helper library and demo app to help in implementing your app server.</li>
-          <li>If you decide to use the XMPP connection server, you can use
-the provided Python or Java <a href="http://www.igniterealtime.org/projects/smack/">
-Smack</a> demo apps as a starting point.</li>
-        <li>Note that Google AppEngine does not support connections to XMPP (CCS).</li>
-        </ul>
-      </li>
-    </ul>
-  </li>
-</ul>
-
-
-<h2 id="choose">Choosing a GCM Connection Server</h2>
-
-<p>Currently GCM provides two connection servers: <a href="{@docRoot}google/gcm/http.html">
-HTTP</a> and <a href="{@docRoot}google/gcm/ccs.html">XMPP (CCS)</a>. You can use them
-separately or in tandem. XMPP (CCS) messaging differs from HTTP messaging in the following ways:</p>
-<ul>
-  <li>Upstream/Downstream messages
-    <ul>
-      <li>HTTP: Downstream only, cloud-to-device up to 4KB of data. </li>
-      <li>XMPP (CCS): Upstream and downstream (device-to-cloud, cloud-to-device),
-        up to 4 KB of data. </li>
-    </ul>
-  </li>
-  <li>Messaging (synchronous or asynchronous)
-    <ul>
-      <li>HTTP: Synchronous. 3rd-party app servers send messages as HTTP POST requests and
-wait for a response. This mechanism is synchronous and blocks the sender from sending
-another message until the response is received.</li>
-      <li>XMPP (CCS): Asynchronous. 3rd-party app servers send/receive messages to/from all their
-devices at full line speed over persistent XMPP connections.
-XMPP (CCS) sends acknowledgment or failure notifications (in the
-form of special ACK and NACK JSON-encoded XMPP messages) asynchronously.</li>
-    </ul>
-  </li>
-
-  <li>JSON
-    <ul>
-      <li>HTTP: JSON messages sent as HTTP POST.</li>
-      <li>XMPP (CCS): JSON messages encapsulated in XMPP messages.</li>
-    </ul>
-  </li>
-  <li>Plain Text
-    <ul>
-      <li>HTTP: Plain Text messages sent as HTTP POST.</li>
-      <li>XMPP (CCS): Not supported.</li>
-    </ul>
-  </li>
-  <li>Multicast downstream send to multiple registration IDs.
-    <ul>
-      <li>HTTP: Supported in JSON message format.</li>
-      <li>XMPP (CCS): Not supported.</li>
-    </ul>
-  </li>
-</ul>

-<h2 id="send-msg">Sending Messages</h2>
-
-<p>This section gives an overview of sending messages. For details of message syntax,
-see <a href="{@docRoot}google/gcm/server-ref.html">Server Reference</a>.</p>
-
-<h3>Overview</h3>
-
-<p>Here is the general sequence of events that occurs when a 3rd-party application
-server sends a message (the details vary depending on the platform):</p>
-<ol>
-  <li>The 3rd-party app server sends a message to GCM servers.</li>
-  <li>The GCM connection server enqueues and stores the message if the device is offline.</li>
-  <li>When the device is online, GCM connection server sends the message to the device.</li>
-  <li>The client app processes the message. </li>
-</ol>
-
-<h3>Implement send request</h3>
-
-<p>The following sections describe the basic components involved in
-sending a request. See the <a href="{@docRoot}google/gcm/server-ref.html">Server Reference</a>
-for details.</p>
-
-<h4 id="target">Target</h4>
-<p>Required. When your app server sends a message in GCM, it must specify a target.</p>
-<p>For HTTP you must specify the target as one of the following:</p>
-<ul>
-<li><code>registration_ids</code>: For sending to 1 or more devices (up to 1000).
-When you send a message to multiple registration IDs, that is called a multicast message.</li>
-<li><code>notification_key</code>: For sending to multiple devices owned by a single user.</li>
-</ul>
-<p>For CCS (XMPP) you must specify the target as:</p>
-<ul>
-<li>{@code to}: This
-field may contain a single registration ID or a notification key.
-XMPP (CCS) does not support multicast messaging.</li>
-</ul>
-
-<h4 id="options">Options</h4>
-
-<p>There are various options the 3rd-party app server can set when sending a downstream
-message to a client app. See the <a href="{@docRoot}google/gcm/server-ref.html#table1">
-Server Reference</a> for details. Here are a few examples of possible options:</p>
-
-<ul>
-  <li>{@code collapse_key}: whether a message should be "send-to-sync" or a "message with
-payload".</li>
-  <li>{@code time_to_live}: setting an expiration date for a message.</li>
-  <li>{@code dry_run}: Test your server.
-<p>If you want to test your request (either JSON or plain text) without delivering
-the message to the devices, you can set an optional HTTP parameter called
-<code>dry_run</code> with the value <code>true</code>. The result will be almost
-identical to running the request without this parameter, except that the message
-will not be delivered to the devices. Consequently, the response will contain fake
-IDs for the message and multicast parameters.</p>
-</li>
-</ul>
-
-<h4 id="payload">Payload</h4>
-<p>Optional. If you are including a payload in the message, you use the <code>data</code>
-parameter to include the payload. This applies for both HTTP and XMPP.</p>
-
-<p>See the <a href="{@docRoot}google/gcm/server-ref.html">Server Reference</a> for details on sending
-and receiving messages.</p>
-
-<h2 id="adv">Messaging Concepts and Best Practices</h2>
-
-<p>This section has a discussion of general messaging topics.</p>
-
-<h3 id="collapsible">Send-to-Sync  vs. Messages with Payload</h3>
-
-<p>Every message sent in GCM has the following characteristics:</p>
-<ul>
-  <li>It has a payload limit of 4096 bytes.</li>
-  <li>By default, it is stored by GCM for 4 weeks.</li>
-</ul>
-
-<p>But despite these similarities, messages can behave very differently depending
-on their particular settings. One major distinction between messages is whether
-they are collapsed (where each new message replaces the preceding message) or not
-collapsed (where each individual message is delivered). Every message sent in GCM
-is either a &quot;send-to-sync&quot; (collapsible) message or a &quot;message with
-payload&quot; (non-collapsible message).</p>
-
-<h4 id="s2s">Send-to-sync messages</h4>
-
-<p>A send-to-sync (collapsible) message is often a &quot;tickle&quot; that tells
-a mobile application to sync data from the server. For example, suppose you have
-an email application. When a user receives new email on the server, the server
-pings the mobile application with a &quot;New mail&quot; message. This tells the
-application to sync to the server to pick up the new email. The server might send
-this message multiple times as new mail continues to accumulate, before the application
-has had a chance to sync. But if the user has received 25 new emails, there's no
-need to preserve every &quot;New mail&quot; message. One is sufficient. Another
-example would be a sports application that updates users with the latest score.
-Only the most recent message is relevant. </p>
-
-<p>GCM allows a maximum of 4 different collapse keys to be used by the GCM server
-at any given time. In other words, the GCM server can simultaneously store 4
-different send-to-sync messages per device, each with a different collapse key.
-For example, Device A can have A1, A2, A3, and A4. Device B can have B1, B2, B3,
-and B4, and so on. If you exceed this number GCM will only keep 4 collapse keys, with no
-guarantees about which ones they will be.</p>
-
-<h3 id="payload">Messages with payload</h3>
-
-<p>Unlike a send-to-sync message, every &quot;message with payload&quot;
-(non-collapsible message) is delivered. The payload the message contains can be
-up to 4kb. For example, here is a JSON-formatted message in an IM application in
-which spectators are discussing a sporting event:</p>
-
-<pre class="prettyprint pretty-json">{
-  "registration_id" : "APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx...",
-  "data" : {
-    "Nick" : "Mario",
-    "Text" : "great match!",
-    "Room" : "PortugalVSDenmark",
-  },
-}</pre>
-
-<p>A &quot;message with payload&quot; is not simply a &quot;ping&quot; to the
-mobile application to contact the server to fetch data. In the aforementioned IM
-application, for example, you would want to deliver every message, because every
-message has different content. To specify a non-collapsible message, you simply
-omit the <code>collapse_key</code> parameter. Thus GCM will send each message
-individually. Note that the order of delivery is not guaranteed.</p>
-
-<p>GCM will store up to 100 non-collapsible messages. After that, all messages
-are discarded from GCM, and a new message is created that tells the client how
-far behind it is.</p>
-
-<p>The application should respond by syncing with the server to recover the
-discarded messages. </p>
-
-<h4 id="which">Which should I use?</h4>
-  <p>If your application does not need to use non-collapsible messages, collapsible
-messages are a better choice from a performance standpoint. However, if you use
-collapsible messages, remember that <strong>GCM only allows a maximum of 4 different collapse
-keys to be used by the GCM server per registration ID at any given time</strong>. You must
-not exceed this number, or it could cause unpredictable consequences.</p>
-
-<h3 id="ttl">Setting an Expiration Date for a Message</h3>
-<p>You can use the <code>time_to_live</code> parameter in the send request
-to specify the maximum lifespan of a message.
-The value of this parameter must be a duration from 0 to 2,419,200 seconds, and
-it corresponds to the maximum period of time for which GCM will store and try to
-deliver the message. Requests that don't contain this field default to the maximum
-period of 4 weeks.</p>
-<p>Here are some possible uses for this feature:</p>
-<ul>
-  <li>Video chat incoming calls</li>
-  <li>Expiring invitation events</li>
-  <li>Calendar events</li>
-</ul>
-<h4 id="bg">Background </h4>
-<p>GCM usually delivers messages immediately after they are sent. However,
-this might not always be possible. For example, if the platform is Android,
-the device could be turned off, offline, or otherwise unavailable.
-Or the sender itself might request
-that messages not be delivered until the device becomes active by using the
-<code>delay_while_idle</code> flag. Finally, GCM might intentionally delay messages
-to prevent an application from consuming excessive resources and negatively
-impacting battery life.</p>
-
-<p>When this happens, GCM will store the message and deliver it as soon as it's
-feasible. While this is fine in most cases, there are some applications for which
-a late message might as well never be delivered. For example, if the message is
-an incoming call or video chat notification, it will only be meaningful for a
-small period of time before the call is terminated. Or if the message is an
-invitation to an event, it will be useless if received after the event has ended.</p>
-
-<p>Another advantage of specifying the expiration date for a message is that GCM
-will never throttle messages with a <code>time_to_live</code> value of 0 seconds.
-In other words, GCM will guarantee best effort for messages that must be delivered
-&quot;now or never.&quot; Keep in mind that a <code>time_to_live</code> value of
-0 means messages that can't be delivered immediately will be discarded. However,
-because such messages are never stored, this provides the best latency for
-sending notifications.</p>
-
-<p>Here is an example of a JSON-formatted request that includes TTL:</p>
-<pre class="prettyprint pretty-json">
-{
-  "collapse_key" : "demo",
-  "delay_while_idle" : true,
-  "registration_ids" : ["xyz"],
-  "data" : {
-    "key1" : "value1",
-    "key2" : "value2",
-  },
-  "time_to_live" : 3
-},
-</pre>
-
-
-<h3 id="multi-senders">Receiving Messages from Multiple Senders</h3>
-
-<p>GCM allows multiple parties to send messages to the same application. For
-example, suppose your application is an articles aggregator with multiple
-contributors, and you want each of them to be able to send a message when they
-publish a new article. This message might contain a URL so that the application
-can download the article. Instead of having to centralize all sending activity in
-one location, GCM gives you the ability to let each of these contributors send
-its own messages.</p>
-
-<p>To make this possible, all you need to do is have each sender generate its own
-project number. Then include those IDs in the sender field, separated by commas,
-when requesting a registration. Finally, share the registration ID with your
-partners, and they'll be able to send messages to your application using their
-own authentication keys.</p>
-
-<p>Note that there is limit of 100 multiple senders.</p>
-
-<h3 id="lifetime">Lifetime of a Message</h3>
-
-<p>When a 3rd-party server posts a message to GCM and receives a message ID back,
-it does not mean that the message was already delivered to the device. Rather, it
-means that it was accepted for delivery. What happens to the message after it is
-accepted depends on many factors.</p>
-
-<p>In the best-case scenario, if the device is connected to GCM, the screen is on,
-and there are no throttling restrictions (see <a href="#throttling">Throttling</a>),
-the message will be delivered right away.</p>
-
-<p>If the device is connected but idle, the message will still be
-delivered right away unless the <code>delay_while_idle</code> flag is set to true.
-Otherwise, it will be stored in the GCM servers until the device is awake. And
-that's where the <code>collapse_key</code> flag plays a role: if there is already
-a message with the same collapse key (and registration ID) stored and waiting for
-delivery, the old message will be discarded and the new message will take its place
-(that is, the old message will be collapsed by the new one). However, if the collapse
-key is not set, both the new and old messages are stored for future delivery.
-Collapsible messages are also called <a href="#s2s">send-to-sync messages</a>.</p>
-
-<p class="note"><strong>Note:</strong> There is a limit on how many messages can
-be stored without collapsing. That limit is currently 100. If the limit is reached,
-all stored messages are discarded. Then when the device is back online, it receives
-a special message indicating that the limit was reached. The application can then
-handle the situation properly, typically by requesting a full sync.
-<br><br>
-Likewise, there is a limit on how many <code>collapse_key</code>s you can have for
-a particular device. GCM allows a maximum of 4 different collapse keys to be used
-by the GCM server per device
-any given time. In other words, the GCM server can simultaneously store 4 different
-send-to-sync messages, each with a different collapse key. If you exceed this number
-GCM will only keep 4 collapse keys, with no guarantees about which ones they will be.
-See <a href="#s2s">Send-to-sync messages</a> for more information.
-</p>
-
-<p>If the device is not connected to GCM, the message will be stored until a
-connection is established (again respecting the collapse key rules). When a connection
-is established, GCM will deliver all pending messages to the device, regardless of
-the <code>delay_while_idle</code> flag. If the device never gets connected again
-(for instance, if it was factory reset), the message will eventually time out and
-be discarded from GCM storage. The default timeout is 4 weeks, unless the
-<code>time_to_live</code> flag is set.</p>
-
-<p>Finally, when GCM attempts to deliver a message to the device and the
-application was uninstalled, GCM will discard that message right away and
-invalidate the registration ID. Future attempts to send a message to that device
-will get a <code>NotRegistered</code> error. See <a href="#unreg">
-How Unregistration Works</a> for more information.</p>
-<p>Although is not possible to track the status of each individual message, the
-Google Cloud Console stats are broken down by messages sent to device, messages
-collapsed, and messages waiting for delivery.</p>
-
-<h3 id="throttling">Throttling</h3>
-<p>To prevent abuse (such as sending a flood of messages to a device) and
-to optimize for the overall network efficiency and battery life of
-devices, GCM implements throttling of messages using a token bucket
-scheme. Messages are throttled on a per application and per <a href="#collapsible">collapse
-key</a> basis (including non-collapsible messages). Each application
-collapse key is granted some initial tokens, and new tokens are granted
-periodically therefter. Each token is valid for a single message sent to
-the device. If an application collapse key exhausts its supply of
-available tokens, new messages are buffered in a pending queue until
-new tokens become available at the time of the periodic grant. Thus
-throttling in between periodic grant intervals may add to the latency
-of message delivery for an application collapse key that sends a large
-number of messages within a short period of time. Messages in the pending
-queue of an application collapse key may be delivered before the time
-of the next periodic grant, if they are piggybacked with messages
-belonging to a non-throttled category by GCM for network and battery
-efficiency reasons.</p>

-      <h4>Add your own style to a pre-built receiver app</h4>
-      <p>Adding support for Google Cast requires that you provide a companion app on the
-      Google Cast device, known as the receiver app. If your app streams audio or video content
-      using one of several supported media types, then you can create a receiver app with your
-      own style and branding by creating nothing more than a CSS file.

-  As a reminder, please note that starting <strong>1 August 2014</strong>, new
-  apps and app updates distributed through Google Play must use the advertising
-  ID in lieu of any other persistent identifiers for any advertising purposes,
-  on devices that support the advertising ID.<br>
-  <br>
-  To learn how to check your app's compliance through the Developer Console, or
-  for details on the associated developer policy changes, please see the
-  <a href=
-  "https://support.google.com/googleplay/android-developer/answer/6048248">Advertising
-  ID topic</a> in the Google Play developer help center.
-</p>
-
-<h2 id="get_started">Using the Advertising ID</h2>
-
-<p>
-  The <strong>advertising ID</strong> is a unique but
-  user-resettable string identifier that lets ad networks and other apps anonymously
-  identify a user. The user's advertising ID is made available to apps through APIs
-  provided in Google Play services.
-</p>
-<p>
-  Users can reset their advertising ID at any time, right from the Ads section of the
-  Google Settings app on their devices. From the same app, users can also
-  opt-out of targeted advertising based on the advertising ID by setting the appropriate
-  <strong style="white-space:nowrap">ad tracking preference</strong>. When the
-  user opts-out of targeted ads, this ad tracking preference is made available
-  to apps through a Google Play services API.
-</p>
-<p>
-  Apps making use of the advertising ID <strong>must check for and respect</strong> the
-  user's ad tracking preference. Also please note that any use of the advertising ID
-  must abide by the terms of the <a class="external-link"
-  href="http://play.google.com/about/developer-content-policy.html#ADID">Google Play
-  Developer Content Policies</a>. 
-</p>
-
-<h3 id="format">Format of the Advertising ID</h3>
-
-<p>
-  Google Play services APIs expose the user's advertising ID as a string format of UUID,
-  with values similar to this:
-</p>
-<p style="margin-left:1.5em;"><code>“38400000-8cf0-11bd-b23e-10b96e40000d”</code></p>
-
-<h3 id="requirements">Requirements</h3>
-
-<ul>
-  <li>The advertising ID APIs are supported in Google Play services 4.0+</li>
-  <li>Support for the advertising ID on specific devices is based on their installed versions 
-  of Google Play services</li>
-</ul>
-
-<h3 id="obtaining">Obtaining the user's advertising ID and ad tracking preference</h3>
-
-<p>
-  If you want to use the advertising ID in your app, you must first install the Google
-  Play services SDK. As noted in the requirements above, you should install the
-  SDK for Google Play services 4.0 or higher if you will develop using the advertising ID
-  APIs. For information about how to get started, see <a href=
-  "{@docRoot}google/play-services/setup.html">Set Up Google Play services</a>.
-</p>
-<p>
-  The advertising ID APIs are available in the <a href=
-  "{@docRoot}reference/com/google/android/gms/ads/identifier/package-summary.html">
-  <code>com.google.android.gms.ads.identifier</code></a> package in the Google
-  Play Services library. To obtain the user's advertising ID and tracking preference,
-  call the method
-  <a href=
-  "{@docRoot}reference/com/google/android/gms/ads/identifier/AdvertisingIdClient.html#getAdvertisingIdInfo(android.content.Context)">
-  <code>getAdvertisingIdInfo()</code></a>, which returns an <a href=
-  "{@docRoot}reference/com/google/android/gms/ads/identifier/AdvertisingIdClient.Info.html">
-  <code>AdvertisingIdClient.Info</code></a> encapsulating the user's current Advertising ID
-  and tracking preference.
-</p>
-
-<p class="note">
-  <strong>Note:</strong> The <code>getAdvertisingIdInfo()</code> method is a
-  blocking call, so you must not call it on the main (UI) thread. If called on
-  the main thread, the method throws <code>IllegalStateException</code>.
-</p>
-
-<p>
-  Once you've retrieved the <code>AdvertisingIdClient.Info</code> object, you
-  can use it's <a href=
-  "{@docRoot}reference/com/google/android/gms/ads/identifier/AdvertisingIdClient.Info.html#getId()">
-  <code>getId()</code></a> and <a href=
-  "{@docRoot}reference/com/google/android/gms/ads/identifier/AdvertisingIdClient.Info.html#isLimitAdTrackingEnabled()">
-  <code>isLimitAdTrackingEnabled()</code></a> methods to access the advertising ID and
-  ad tracking preference.
-</p>
-
-<table>
-<tr>
-<th>Method</th>
-<th>Description</th>
-</tr>
-<tr>
-<td><code>public String getId()</code></td>
-<td style="white-space:nowrap;">Retrieves the advertising ID.</td>
-</tr>
-<tr>
-<td style="white-space:nowrap;"><code>public boolean isLimitAdTrackingEnabled()</code></td>
-<td>Retrieves whether the user has limit ad tracking enabled or not.</td>
-</tr>
-</table>
-
-<p>
-  The advertising ID APIs do not include a "reset" method. Only users can initiate a
-  reset of their own advertising IDs, through the Google Settings application.
-</p>
-<p>
-  For more information about the advertising ID APIs, see the <a href=
-  "{@docRoot}reference/com/google/android/gms/ads/identifier/package-summary.html">
-  reference documentation</a>.
-</p>
-
-<h3 id="example">Example implementation</h3>
-
-<p>
-  Here's a basic illustration of how you can retrieve the user's advertising ID and ad
-  tracking preference in your app:
-</p>
-
-<pre>
-import com.google.android.gms.ads.identifier.AdvertisingIdClient;
-import com.google.android.gms.ads.identifier.AdvertisingIdClient.Info;
-import com.google.android.gms.common.GooglePlayServicesAvailabilityException;
-import com.google.android.gms.common.GooglePlayServicesNotAvailableException;
-import java.io.IOException;

-// Do not call this function from the main thread. Otherwise, 
-// an IllegalStateException will be thrown.
-public void getIdThread() {

-    adInfo = AdvertisingIdClient.getAdvertisingIdInfo(mContext);
-
-  } catch (IOException e) {
-    // Unrecoverable error connecting to Google Play services (e.g.,
-    // the old version of the service doesn't support getting AdvertisingId).
- 
-  } catch (GooglePlayServicesAvailabilityException e) {
-    // Encountered a recoverable error connecting to Google Play services. 
-
-  } catch (GooglePlayServicesNotAvailableException e) {
-    // Google Play services is not available entirely.

-<p>The Fused Location Provider intelligently manages the underlying location technology and gives you the best location according to your needs. </p>
-
-<ul>
-    <li>
-        <em>Simple APIs</em>: Lets you specify high-level needs like "high accuracy" or "low power", instead of
-        having to worry about location providers.
-    </li>
-    <li>
-        <em>Immediately available</em>: Gives your apps immediate access to the best, most recent location.
-    </li>
-    <li>
-        <em>Power-efficiency</em>: Minimizes your app's use of power. Based on all incoming location requests and available sensors, fused location provider chooses the most efficient way to meet those needs.
-    </li>
-    <li>
-        <em>Versatility</em>: Meets a wide range of needs, from foreground uses that need highly accurate
-        location to background uses that need periodic location updates with negligible power impact.
-    </li>
-
-</ul>
-
-<h4 style="font-weight:bold">Geofencing APIs</h4>
-
-<p>Lets your app setup geographic boundaries around specific locations and then receive notifications when the user enters or leaves those areas. </p>

-    <li>
-        <em>Simple but powerful APIs</em>: Allows batch addition and removal of geofences. Ability to manage
-        multiple geofences at the same time. Ability to filter alerts for both entry and exit or
-        entry only or exit only.
-    </li>
-    <li>
-        <em>Optimized for battery</em>: Adjusts location updates based on user’s proximity to the geofence
-        and user’s modality (still, walking, driving, and so on).

-
-<p>The Activity recognition API makes it easy to check the user’s current activity&mdash;still, walking, cycling, and in-vehicle&mdash;with very efficient use of the battery:</p>
-<ul>
-    <li>
-        <em>Optimized for battery</em>: Uses low-power sensors to recognize the user's current physical activity.
-    </li>
-    <li>
-        <em>Enhances other services with context</em>: Great for adding movement awareness to location awareness. Apps can adjust the amount of
-        location awareness they provide, based on the current user movement. For example, a
-        navigation app can request more frequent updates when the user is driving.
-    </li>
-    <li>
-        <em>Advanced activity detection</em>: For apps that want to do their own
-        post-processing, the activity APIs provide confidence values for each of the activities.
-        It also includes two activities that indicate unreliable measurements: unknown and tilt.

+<p>API Level: M</p>
+<p>Along with new features and capabilities, M includes a variety of
+system changes and API behavior changes. This document highlights
+some of the key changes that you should be understand and account for in your apps.</p>
+
+<p>If you have previously published an app for Android, be aware that your app
+  might be affected by these changes in M.</p>
+
+<h2 id="behavior-runtime-permissions">Runtime Permissions</h1>
+<p>This release introduces a new runtime permissions model, where users can now directly manage
+their app permissions at runtime. This model gives users improved visibility and control over
+permissions, while streamlining the installation and auto-update processes for app developers.
+Users can set permissions on or off for all apps running on Android M. However, apps that don’t
+target M cannot request permissions at runtime.</p>
+
+<p>On your apps that target M, make sure to check and request for permissions at
+runtime. To determine if your app has been granted a permission, call the
+new {@code Context.checkSelfPermission()} method. To request for a permission, call the new
+{@code Activity.requestPermission()} method.</p>
+
+<p>For more information on supporting the new permissions model in your app, see the
+<a href="{@docRoot}preview/features/runtime-permissions.html">

+<h2 id="behavior-openssl">OpenSSL</h2>
+<p>Android is moving away from OpenSSL to the
+<a href="https://boringssl.googlesource.com/boringssl/" class="external-link">BoringSSL</a>
+library. If you’re using the Android NDK in your app, don't link against cryptographic libraries
+that are not a part of the NDK API, such as {@code libcrypto.so} and {@code libssl.so}. These
+libraries are not public APIs, and may change or break without notice across releases and devices.
+In addition, you may expose yourself to security vulnerabilities. Instead, modify your
+native code to call the Java cryptography APIs via JNI or to statically link against a
+cryptography library of your choice.</p>
+
+<h2 id="behavior-project-volta">Project Volta</h2>
+<p>This release introduces new power-saving optimizations for idle devices and apps.</p>
+
+<h3 id="behavior-doze">Doze mode</h3>
+<p>If a device is unplugged and not used for up to an hour, it goes into <em>doze</em> mode where
+it attempts to keep the system in a sleep state. In this mode, devices may briefly resume normal
+operations for up to 5 minutes every few hours so that app syncing can occur and the system can
+perform any pending operations.</p>
+
+<p>The following restrictions apply to your apps while in device doze mode:</p>
+<ul>
+<li>Network access is disabled</li>
+<li>Alarms scheduled with the {@link android.app.AlarmManager} class are disabled, except for
+alarms that you've set with the
+{@link android.app.AlarmManager#setAlarmClock(android.app.AlarmManager.AlarmClockInfo,android.app.PendingIntent) setAlarmClock()}
+method</li>
+<li>WiFi scans are not performed</li>
+<li>Syncs and jobs for your sync adapters and {@link android.app.job.JobScheduler} are not
+permitted to run</li>
+</ul>
+</p>
+<p>When the system comes out of doze mode, it executes jobs and syncs that are pending.</p>
+
+<h3 id="behavior-app-standby">App standby mode</h3>
+<p>In M, the system may determine that apps are idle when they are not in active use by the user.
+Your app goes into <em>app standby</em> mode after two days unless the system detects any of these
+signals:</p>
+
+<ul>
+<li>The app has a process currently in the foreground (either as an activity or foreground service,
+or in use by another activity or foreground service)</li>
+<li>The app generates a notification that the user can see</li>
+<li>The user explicitly asks for the app to remain running</li>
+</ul>
+
+<p>If the system is running on battery power, apps that are in standby mode will have their
+network access disabled and their syncs and jobs suspended. When the system is plugged into a power
+supply, it brings an app out of standby mode and executes any jobs and syncs that are pending.</p>
+
+<p>Apps that use <a href="{@docRoot}google/gcm/index.html">Google Cloud Messaging</a> will
+continue to receive messages even if they are idle. When the system is plugged into a power
+supply, apps resume normal operations and can run any pending syncs and jobs.</p>
+
+<p>You can test this feature by connecting a device running M to your development machine and
+calling the following commands:
+</p>
+<pre>
+$ adb shell am broadcast -a android.os.action.DISCHARGING
+$ adb shell am set-idle &lt;packageName&gt; true
+$ adb shell am set-idle &lt;packageName&gt; false
+$ adb shell am get-idle &lt;packageName&gt;
+</pre>
+
+<h2 id="behavior-adoptable-storage">Adoptable Storage Devices</h2>
+<p>
+In M, users can adopt external storage devices such as SD cards. Adopting an external storage
+device encrypts and formats the device to behave like internal storage. This feature allows users
+to move both apps and private data of those apps between storage devices. When moving apps, the
+system respects the <a href="{@docRoot}guide/topics/manifest/manifest-element.html#install">
+{@code android:installLocation}</a> preference in the manifest.</p>
+
+<p>If your app accesses the following APIs or fields, be aware that the file paths they return
+will dynamically change when the app is moved between internal and external storage devices.
+When building file paths, it is strongly recommended that you always call these APIs dynamically.
+Don’t use hardcoded file paths or persist fully-qualified file paths that were built previously.</p>
+
+<ul>
+<li>{@link android.content.Context} methods:
+    <ul>
+        <li>{@link android.content.Context#getFilesDir() getFilesDir()}</li>

+    </ul>
+</li>
+</ul>
+
+<p>To debug this feature in the developer preview, you can enable adoption of a USB drive that is
+connected to an Android device through a USB On-The-Go (OTG) cable, by running these
+commands:</p>
+
+<pre>
+$ adb root
+$ sleep 2
+$ adb shell setprop persist.fw.force_adoptable 1
+$ adb reboot
+</pre>
+
+<h2 id="behavior-apache-http-client">Apache HTTP Client Removal</h2>
+<p>This release removes support for the Apache HTTP client. If your app is using this client and
+targets Android 2.3 (API level 9) or higher, use the {@link java.net.HttpURLConnection} class
+instead. This API is more efficient because it reduces network use through transparent compression
+and response caching, and minimizes power consumption. To continue using the Apache HTTP APIs, you
+must first declare the following compile-time dependency in your {@code build.gradle} file:
+</p>
+<pre>
+android {
+    compileSdkVersion M
+    useLibrary 'org.apache.http.legacy'
+}
+</pre>
+
+<h2 id="behavior-audiomanager-Changes">AudioManager Changes</h2>
+<p>Setting the volume directly or muting specific streams via the {@link android.media.AudioManager}
+class is no longer supported. The {@link android.media.AudioManager#setStreamSolo(int,boolean)
+setStreamSolo()} method is deprecated, and you should call the
+{@code AudioManager.requestAudioFocus()} method instead. Similarly, the
+{@link android.media.AudioManager#setStreamMute(int,boolean) setStreamMute()} method is
+deprecated; instead, call the {@code AudioManager.adjustStreamVolume()} method
+and pass in the direction value {@code ADJUST_MUTE} or {@code ADJUST_UNMUTE}.</p>
+
+<h2 id="behavior-test-selection">Text Selection</h2>
+
+<img src="{@docRoot}preview/images/text-selection.gif"
+style="float:right; margin:0 0 20px 30px" width="270" height="480" />
+
+<p>When users selects text in your app, you can now display text selection actions such as
+<em>Cut</em>, <em>Copy</em>, and <em>Paste</em> in a
+<a href="http://www.google.com/design/spec/patterns/selection.html#selection-text-selection"
+class="external-link">floating toolbar</a>. The user interaction implementation is similar to that
+for the contextual action bar, as described in
+<a href="{@docRoot}guide/topics/ui/menus.html#CABforViews">
+Enabling the contextual action mode for individual views</a>.</p>
+
+<p>To implement a floating toolbar for text selection, make the following changes in your existing
+apps:</p>
+<ol>
+<li>In your {@link android.view.View} or {@link android.app.Activity} object, change your
+{@link android.view.ActionMode} calls from
+{@code startActionMode(Callback)} to {@code startActionMode(Callback, ActionMode.TYPE_FLOATING)}.</li>
+<li>Take your existing implementation of ActionMode.Callback and make it extend
+{@code ActionMode.Callback2} instead.</li>
+<li>Override the {@code Callback2.onGetContentRect()} method to provide the coordinates of the
+content {@link android.graphics.Rect} object (such as a text selection rectangle) in the view.</li>
+<li>If the rectangle positioning is no longer valid, and this is the only element to be invalidated,
+call the {@code ActionMode.invalidateContentRect()} method.</li>
+</ol>
+
+<p>If you are using <a href="{@docRoot}tools/support-library/index.html">
+Android Support Library</a> revision 22.2, be aware that floating toolbars are not
+backward-compatible and appcompat takes control over {@link android.view.ActionMode} objects by
+default. This prevents floating toolbars from being displayed in M. To enable
+{@link android.view.ActionMode} support in an
+{@link android.support.v7.app.AppCompatActivity}, call
+{@code android.support.v7.app.AppCompatActivity.getDelegate()}, then call
+{@code android.support.v7.app.AppCompatDelegate.setHandleNativeActionModesEnabled()} on the returned
+{@link android.support.v7.app.AppCompatDelegate} object and set the input
+parameter to {@code false}. This call returns control of {@link android.view.ActionMode} objects to
+the framework. In devices running M, that allows the framework to support
+{@link android.support.v7.app.ActionBar} or floating toolbar modes, while on pre-M devices, only the
+{@link android.support.v7.app.ActionBar} modes are supported.</p>
+
+<h2 id="behavior-keystore">Android Keystore Changes</h2>
+<p>Starting this release, the
+<a href="{@docRoot}training/articles/keystore.html">Android Keystore provider</a> no longer supports
+DSA. ECDSA is still supported.</p>
+
+<p>Keys which do not require encryption at rest will no longer be deleted when secure lock screen
+is disabled or reset (for example, by the user or a Device Administrator). Keys which require
+encryption at rest will be deleted during these events.</p>
+
+<h2 id="behavior-themeable-colorstatelists">Themeable ColorStateLists</h2>
+<p>Theme attributes are now supported in
+{@link android.content.res.ColorStateList} for devices running M. The
+{@link android.content.res.Resources#getColorStateList(int) getColorStateList()} and
+{@link android.content.res.Resources#getColor(int) getColor()} methods have been deprecated. If
+you are calling these APIs, call the new {@code Context.getColorStateList()} or
+{@code Context.getColor()} methods instead. These methods are also available in the
+v4 appcompat library via {@link android.support.v4.content.ContextCompat}.</p>
+
+<h2 id="night-mode">Night Mode (User-configurable Dark Theme)</h2>
+<p>
+Support for the {@code -night} resource qualifier has been updated in M. Previously, night mode was
+only available when a device was docked and in car mode. Starting in M, night mode is available on
+all devices and is user-configurable via <em>Settings > Display > Theme</em>. You can adjust this
+setting globally using {@link android.app.UiModeManager#setNightMode(int) setNightMode()}. The
+Dark theme corresponds to {@link android.app.UiModeManager#MODE_NIGHT_YES}. When the device is in
+night mode, the resource framework will prefer resources that have the -night qualifier. To
+take advantage of user-configurable Dark mode in your app, extend from the
+{@code Theme.Material.DayNight} set of themes rather than {@code Theme.Material} or
+{@code Theme.Material.Light}.
+</p>
+
+<h2 id="behavior-art-runtime">ART Runtime</h2>
+<p>The ART runtime now properly implements access rules for the
+{@link java.lang.reflect.Constructor#newInstance(java.lang.Object...) newInstance()} method. This
+change fixes a problem where Dalvik was checking access rules incorrectly in previous versions.
+If your app uses the
+{@link java.lang.reflect.Constructor#newInstance(java.lang.Object...) newInstance()} method and you
+want to override access checks, call the
+{@link java.lang.reflect.Constructor#setAccessible(boolean) setAccessible()} method with the input
+parameter set to {@code true}. If your app uses the
+<a href="{@docRoot}tools/support-library/features.html#v7">v7 appcompat library</a> or the
+<a href="{@docRoot}tools/support-library/features.html#v7-recyclerview">v7 recyclerview library</a>,
+you must update your app to use to the latest versions of these libraries. Otherwise, make sure that
+any custom classes referenced from XML are updated so that their class constructors are accessible.</p>
+
+<p>The M release updates the behavior of the dynamic linker. The dynamic linker now understands the
+difference between a library’s {@code soname} and its path
+(<a href="https://code.google.com/p/android/issues/detail?id=6670" class="external-link">
+public bug 6670</a>), and search by {@code soname} is now
+implemented. Apps which previously worked that have bad {@code DT_NEEDED} entries
+(usually absolute paths on the build machine’s file system) may fail when loaded on M.</p>
+
+<p>The {@code dlopen(3) RTLD_LOCAL} flag is now correctly implemented in M. Note that
+{@code RTLD_LOCAL} is the default, so calls to {@code dlopen(3)} that didn’t explicitly use
+{@code RTLD_LOCAL} will be affected (unless your app explicitly used {@code RTLD_GLOBAL}). With
+{@code RTLD_LOCAL}, symbols will not be made available to libraries loaded by later calls to
+{@code dlopen(3)} (as opposed to being referenced by {@code DT_NEEDED} entries).</p>
+</p>
+
+<h2 id="behavior-afw">Android for Work Changes</h2>
+<p>This release includes the following behavior changes for Android for Work:</p>
+<ul>
+<li><strong>Work contacts in personal contexts.</strong> Google Messenger and the Google Dialer
+Call Log now display work contacts when the user views past messages or calls. Furthermore, both
+work and personal contacts are now available to devices over Bluetooth, but you can hide work
+profile contacts through a device policy by calling the new
+{@code DevicePolicyManager.setBluetoothContactSharingDisabled()} method. Initiating a call or
+creating a new message will only show personal contacts, as consistent with the experience in
+Android 5.0.
+</li>
+<li><strong>WiFi configuration removal:</strong> WiFi configurations added by a Profile Owner
+(for example, through calls to the
+{@link android.net.wifi.WifiManager#addNetwork(android.net.wifi.WifiConfiguration)
+addNetwork()} method) are now removed if that work profile is deleted.</li>
+<li><strong>WiFi configuration lockdown:</strong> Any WiFi configuration created by an active Device
+Owner can no longer be modified or deleted by the user. The user can still create and
+modify their own WiFi configurations, so long as the {@link android.os.UserManager} constant
+{@link android.os.UserManager#DISALLOW_CONFIG_WIFI} has not been set for that user.</li>
+<li><strong>VPN in Settings:</strong> VPN apps are now visible in <em>Settings > More > VPN</em>.
+Additionally, the notifications that accompany VPN usage are now specific to whether that VPN is
+configured for a managed profile or the entire device.</li>
+<li><strong>Work status notification:</strong> A status bar briefcase icon now appears whenever
+an app from the managed profile has an activity in the foreground. Furthermore, if the device is
+unlocked directly to the activity of an app in the managed profile, a toast is displayed notifying
+the user that they are within the work profile.
+</li>
+<li><strong>Download Work Policy Controller via Google account addition:</strong> When a Google
+account that requires management via a Work Policy Controller (WPC) app is added to a device
+outside of a managed context, the add account flow now prompts the user to install the
+appropriate WPC. This behavior also applies to accounts added via
+<em>Settings > Accounts</em> in the initial device setup wizard.</li>
+</ul>

+<h2 id="backup">Auto Backup for Apps</h2>
+<p>The system now performs automatic full data backup and restore for apps. This behavior is
+enabled by default for apps targeting M; you do not need to add any additional code. If users
+delete their Google account, their backup data is deleted as well.</p>

+see the <a href="">App Backup for Apps guide</a>.</p>
+
+<h2 id="notifications">Notifications</h2>
+<p>M adds the following API changes for notifications:</p>
+<ul>
+  <li>New {@code NotificationListenerService.INTERRUPTION_FILTER_ALARMS} filter level that
+    corresponds to the new <em>Alarms only</em> do not disturb mode.</li>
+  <li>New {@code Notification.CATEGORY_REMINDER} category value that is used to distinguish
+  user-scheduled reminders from other events
+  ({@link android.app.Notification#CATEGORY_EVENT}) and alarms
+  ({@link android.app.Notification#CATEGORY_ALARM}).</li>
+  <li>New {@code android.graphics.drawable.Icon} class which can be attached to your notifications
+    via the Notification.Builder.setIcon() and Notification.Builder.setLargeIcon() methods.</li>
+  <li>New {@code NotificationManager.getActiveNotifications()} method that allows your apps to
+    find out which of their notifications are currently alive.</li>
+</ul>
+
+<h2 id="authentication">Authentication</h2>
+<p>The M release offers new APIs to let you authenticate users by using their fingerprint scans on
+supported devices, and check how recently the user was last authenticated using a device unlocking
+mechanism (such as a lockscreen password). Use these APIs in conjunction with
+the <a href="{@docRoot}training/articles/keystore.html">Android Keystore system</a>.</p>
+
+<h3 id="fingerprint-authentication">Fingerprint Authentication</h3>
+
+<p>To authenticate users via fingerprint scan, get an instance of the new
+{@code android.hardware.fingerprint.FingerprintManager} class and call the
+{@code FingerprintManager.authenticate()} method. Your app must be running on a device with a
+fingerprint sensor. You must implement the user interface for the fingerprint
+authentication flow on your app, and use the standard fingerprint Android icon in your UI.
+If you are developing multiple apps that use fingerprint authentication, note that each app must
+authenticate the user’s fingerprint independently.
 </p>

+style="margin:0 0 10px 20px" width="282" height="476" />
 
+<p>To use this feature in your app, first add the {@code USE_FINGERPRINT} permission in your
+manifest.</p>
 
-<h2 id="id">Feature Group 1</h2>

+        android:name="android.permission.USE_FINGERPRINT" /&gt;
+</pre>
 
-<h3 id="id">Feature item 1</h3>
+<p>The following snippet shows how you might listen for fingerprint events in your
+{@code FingerprintManager.AuthenticationCallback} implementation.</p>

+    mCancellationSignal = new CancellationSignal();
+    mSelfCancelled = false;
+    mFingerprintManager.authenticate(cryptoObject,
+            mCancellationSignal, this, 0 /* flags */);
+    // Icon to display when prompting users to start a fingerprint scan
+    mIcon.setImageResource(R.drawable.ic_fp_40px);
+}
+
+// Helper method to check if the device supports fingerprint
+// scanning and if the user has enrolled at least one fingerprint.
+public boolean isFingerprintAuthAvailable() {
+    return mFingerprintManager.isHardwareDetected()
+        &amp;&amp; mFingerprintManager.hasEnrolledFingerprints();
+}
+</pre>
+
+<h3 id="confirm-credentials">Confirm Credentials</h3>
+<p>Your app can authenticate users based on how recently they last unlocked their device. You can
+use the same public or secret key to authenticate users into multiple apps. This feature frees
+users from having to remember additional app-specific passwords, and avoids the need for you to
+implement your own authentication user interface.</p>
+
+<p>You can set your own authentication policy by setting constraints against the key that you are
+generating or importing. To set the constraints for using a key, use the
+{@code android.security.KeyPairGeneratorSpec.Builder} and
+{@code android.security.KeyGeneratorSpec.Builder} classes for public key pairs and secret keys
+respectively. If you are importing keys, use the {@link android.security.KeyStoreParameter.Builder}
+class to set your constraints.</p>
+
+<p>The following example shows how you might create a symmetric key in the Keystore which can only be
+used if the user has successfully unlocked the device within the last 5 minutes.</p>
+
+<pre>
+private void createKey() {
+    // Generate a key to decrypt payment credentials, tokens, etc.
+    // This will most likely be a registration step for the user when
+    // they are setting up your app.
+    try {
+        KeyStore ks = KeyStore.getInstance("AndroidKeyStore");
+        ks.load(null);
+        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES",
+                "AndroidKeyStore");
+        keyGenerator.init(new KeyGeneratorSpec.Builder(this)
+                // Alias of the entry in Android KeyStore where the key will appear
+                .setAlias(KEY_NAME)
+                // Key use constraints
+                .setPurposes(KeyStoreKeyProperties.Purpose.ENCRYPT
+                    | KeyStoreKeyProperties.Purpose.DECRYPT)
+                .setBlockModes("CBC")
+                .setUserAuthenticationRequired(true)
+                // Require that the user has unlocked in the last 5 minutes
+                .setUserAuthenticationValidityDurationSeconds(5 * 60)
+                .setEncryptionPaddings("PKCS7Padding")
+                .build());
+        keyGenerator.generateKey();
+    } catch (NoSuchAlgorithmException | NoSuchProviderException
+            | InvalidAlgorithmParameterException | KeyStoreException
+            | CertificateException | IOException e) {
+          throw new RuntimeException(e);
+    }
+}
+</pre>
+
+<p>To determine the last time users logged into their account, call the
+{@code android.accounts.AccountManager.confirmCredentials()} method. If the call is successful, the
+method returns an bundle that includes a {@code KEY_LAST_AUTHENTICATED_TIME} value which indicates
+the last time, in milliseconds, that the credential for that account was validated or created.</p>

+
+<p>This release provides you with APIs to makes sharing intuitive and quick for users. You can now
+define <em>deep links</em> that target a specific activity in your app. These deep links are
+exposed to users via the <em>Share</em> menu. This feature allows users to share content to
+targets, such as contacts, within other apps. For example, the deep link might launch an
+activity in another social network app, which lets the user share content directly to a specific
+friend or community in that app.</p>
+
+<p>To enable sharing via deep links, you must define a class that extends the
+{@code android.service.} <br>
+{@code chooser.ChooserTargetService} class. Declare your
+{@code ChooserTargetService} in the manifest. Within that declaration, specify the
+{@code BIND_CHOOSER_TARGET_SERVICE} permission and an intent filter with the
+{@code SERVICE_INTERFACE} action.</p>
+<p>The following example shows how you might declare the {@code ChooserTargetService} in your
+manifest.</p>
+<br>
+<br>
+<br>
+<pre>
+&lt;service android:name=".ChooserTargetService"
+        android:label="&#64;string/service_name"
+        android:permission="android.permission.BIND_CHOOSER_TARGET_SERVICE"&gt;
+    &lt;intent-filter&gt;
+        &lt;action android:name="android.service.chooser.ChooserTargetService" /&gt;
+    &lt;/intent-filter&gt;
+&lt;/service&gt;
+</pre>
+
+<p>For each activity that you want to expose to the {@code ChooserTargetService}, add a
+{@code &lt;meta-data&gt;} element with the name
+{@code "android.service.chooser.chooser_target_service"} in your app manifest.

+<p>The M release provides improved support for user input using a Bluetooth stylus. If the user
+touches a stylus with a button on the screen of your app, the
+{@link android.view.MotionEvent#getToolType(int) getTooltype()} method now returns
+{@code TOOL_TYPE_STYLUS}. The {@link android.view.MotionEvent#getButtonState() getButtonState()}
+method returns {@link android.view.MotionEvent#BUTTON_SECONDARY} when the user
+presses the primary stylus button. If the stylus has a second button, the same method returns
+{@link android.view.MotionEvent#BUTTON_TERTIARY} when the user presses it. If the user presses
+both buttons simultaneously, the method returns both these values. In addition, the system reports
+the user button-press action to the new {@code View.onStylusButtonPressListener} and
+{@code GestureDetector.OnStylusButtonPressListener} callbacks in your activity, if you have
+registered these listeners in your app.</p>

+<h2 id="afw">New Android for Work Features</h2>
+<p>This release includes the following new APIs for Android for Work:</p>
+<ul>
+  <li><strong>Enhanced controls for Corporate-Owned, Single-Use devices:</strong> The Device Owner
+can now control the following settings to improve management of
+Corporate-Owned, Single-Use (COSU) devices:
+  <ul>
+    <li>Disable or re-enable the keyguard with the
+{@code DevicePolicyManager.setKeyguardEnabledState()} method.</li>
+    <li>Disable or re-enable the status bar (including quick settings, notifications, and the
+navigation swipe-up gesture that launches Google Now) with the
+{@code DevicePolicyManager.setStatusBarEnabledState()} method.</li>
+    <li>Disable or re-enable safe boot with the {@link android.os.UserManager} constant
+{@code DISALLOW_SAFE_BOOT}.</li>
+    <li>Prevent the screen from turning off while plugged in with the
+  {@link android.provider.Settings.Global} constant {@code STAY_ON_WHILE_PLUGGED_IN}.</li>
+  </ul>
+  </li>
+  <li><strong>Silent install and uninstall of apps by Device Owner:</strong> A Device Owner can now
+silently install and uninstall applications using the {@link android.content.pm.PackageInstaller}
+APIs, independent of Google Play for Work. You can now provision devices through a Device Owner that
+fetches and installs apps without user interaction. This feature is useful for enabling one-touch
+provisioning of kiosks or other such devices without activating a Google account.</li>
+<li><strong>Silent enterprise certificate access: </strong> When an app calls
+{@link android.security.KeyChain#choosePrivateKeyAlias(android.app.Activity,android.security.KeyChainAliasCallback,java.lang.String[],java.security.Principal[],java.lang.String,int,java.lang.String) choosePrivateKeyAlias()},
+prior to the user being prompted to select a certificate, the Profile or Device Owner can now call
+the {@code DeviceAdminReceiver.onChoosePrivateKeyAlias()} method to provide the alias silently to
+the requesting application. This feature lets you grant managed apps access to certificates
+without user interaction.</li>
+<li><strong>Auto-acceptance of system updates.</strong> By setting a system update policy with
+{@code DevicePolicyManager.setSystemUpdatePolicy()}, a Device Owner can now auto-accept a system
+update, for instance in the case of a kiosk device, or postpone the update and prevent it being
+taken by the user for up to 30 days. Furthermore, an administrator can set a time window in which an
+update must be taken, for example during the hours when a kiosk device is not in use. When a
+system update is available, the system checks if the Work Policy Controller app has set a system
+update policy, and behaves accordingly.
+</li>
+<li>
+<strong>Delegated certificate installation.</strong> A Profile or Device Owner can now grant a
+third-party app the ability to call these {@link android.app.admin.DevicePolicyManager} certificate
+management APIs:
+<ul>
+  <li>{@link android.app.admin.DevicePolicyManager#getInstalledCaCerts(android.content.ComponentName)
+getInstalledCaCerts()}</li>
+  <li>{@link android.app.admin.DevicePolicyManager#hasCaCertInstalled(android.content.ComponentName,byte[])
+hasCaCertInstalled()}</li>
+  <li>{@link android.app.admin.DevicePolicyManager#installCaCert(android.content.ComponentName,byte[])
+installCaCert()}</li>
+  <li>{@link android.app.admin.DevicePolicyManager#uninstallCaCert(android.content.ComponentName,byte[])
+uninstallCaCert()}</li>
+  <li>{@link android.app.admin.DevicePolicyManager#uninstallAllUserCaCerts(android.content.ComponentName)
+uninstallAllUserCaCerts()}</li>
+  <li>{@link android.app.admin.DevicePolicyManager#installKeyPair(android.content.ComponentName,java.security.PrivateKey,java.security.cert.Certificate,java.lang.String)
+installKeyPair()}</li>
+</ul>
+</li>
+<li><strong>Enterprise factory reset protection.</strong> When provisioning a Device Owner, you can
+now configure parameters for bypassing Factory Reset Protection (FRP), by setting the
+{@code DeviceManagerPolicy.EXTRA_PROVISIONING_RESET_PROTECTION_PARAMETERS} bundle. An NFC Programmer
+app can provide these parameters after a device has been reset to bypass FRP and provision the device,
+without requiring the previously configured Google account. If you don't modify these parameters,
+FRP remains in-place and prevents the device from being activated without the previously activated
+Google credentials.</li>
+<li><strong>Data usage tracking.</strong> A Profile or Device Owner can now query for the data
+usage statistics visible in <em>Settings > Data</em> usage by using the new
+{@code android.app.usage.NetworkStatsManager} methods. Profile Owners are automatically granted
+permission to query data on the profile they manage, while Device Owners get access to usage data
+of the managed primary user.</li>
+</ul>

+page.title=Automatic App Data Backup
+page.tags=backup
+
+@jd:body
+
+<p>
+  Users often invest significant time and effort collecting data and setting preferences within
+  apps. Preserving that data for users if they replace a broken device or upgrade to a new one is
+  an important part of ensuring a great user experience. The Android M Preview system helps ensure
+  a good experience for users in this circumstances by automatically backing up app data to the
+  cloud.
+</p>
+
+<p>
+  This behavior is enabled by default for all apps installed on devices running Android M or
+  higher. No additional app code is required. The system provides users with the ability opt out of
+  automatic data backups for individual apps. You can also choose to limit what data from your app
+  is backed up.
+</p>
+
+<p>
+  This document describes the new system behavior and how to specify what data is backed up for
+  your app.
+</p>
+
+<h2>Overview</h2>
+
+<p>
+  The automatic backup feature preserves the data your app creates on a user device by uploading to
+  the user’s Google Drive account and encrypting it. There is no charge to you or the user for data
+  storage and the saved data does not count towards the user's personal Drive quota. During the M
+  Preview period, users can store up to 25MB per Android app.
+</p>
+
+<p>
+  Automatic backups occur every 24 hours, when the device is idle, charging, and connected to a
+  Wi-Fi network. When these conditions are met, the Backup Manager service uploads all available
+  backup data to the cloud. When the user transitions to a new device, or uninstalls and reinstalls
+  the backed up application, a restore operation will take place, copying the backed up data into
+  the newly installed application’s data directory.
+</p>
+
+
+<h3>Automatically Excluded Data Files</h3>
+
+<p>
+  Not all app data should be backed up, such as temporary files and caches, so the automatic backup
+  service excludes certain data files by default:
+</p>
+
+<ul>
+  <li>Files in the directories referred to by the <code><a href=
+  "{@docRoot}reference/android/content/Context.html#getCacheDir()">getCacheDir()</a></code> and
+  <code><a href=
+  "{@docRoot}reference/android/content/ContextWrapper.html#getCodeCacheDir()">getCodeCacheDir()</a></code>
+  methods.
+  </li>
+
+  <li>Files located on external storage, unless they reside in the directory referred to by the
+  <code><a href=
+  "{@docRoot}reference/android/content/Context.html#getExternalFilesDir(java.lang.String)">getExternalFilesDir()</a></code>
+  method.
+  </li>
+
+  <li>Files located in the directory referred to by the <code><a href=
+  "{@docRoot}reference/android/content/Context.html#getNoBackupFilesDir()">getNoBackupFilesDir()</a></code>
+  method.
+  </li>
+</ul>
+
+<h2>Configuring Data Backup</h2>
+
+<p>
+  The data created by any app installed on an M device is backed up, except for the automatically
+  excluded files listed in the previous section. You can further limit and configure what data gets
+  backed up from your app using settings in your app manifest.
+</p>
+
+<h3>Including or Excluding Data</h3>
+
+<p>
+  Depending on what data your application needs and how you save it, you may need to set specific
+  rules for including or excluding certain files or directories. The automatic backup service
+  supports setting these backup rules through use of an XML configuration file and the app
+  manifest. In the app manifest, you can specify a backup scheme configuration file as shown in the
+  following example:
+</p>
+
+<pre>
+&lt;?xml version="1.0" encoding="utf-8"?&gt;
+&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
+        xmlns:tools="http://schemas.android.com/tools"
+        package="com.my.appexample"&gt;
+    &lt;uses-sdk android:minSdkVersion="9"/&gt;
+    &lt;uses-sdk android:targetSdkVersion="android-MNC"/&gt;
+    &lt;application ...
+<strong>        android:fullBackupContent="&#64;xml/mybackupscheme"&gt;</strong>
+    &lt;/application&gt;
+    ...
+&lt;/manifest&gt;
+</pre>
+
+<p>
+  In this example code, the android:fullBackupContent attribute specifies an XML file, located in
+  the <code>res/xml/</code> directory of your app development project, named
+  <code>mybackupscheme.xml</code>. This configuration file can include rules for what files are
+  backed up. The following example code shows a configuration file that excludes a specific file
+  from backups:
+</p>
+
+<pre>
+&lt;?xml version="1.0" encoding="utf-8"?&gt;
+	&lt;full-backup-content&gt;
+    &lt;exclude domain="database" path="device_info.db"/&gt;
+&lt;/full-backup-content&gt;
+</pre>
+
+<p>
+  This backup configuration only excludes a specific database file from being backed up. All other
+  files are backed up.
+</p>
+
+<h4>Backup Configuration Syntax</h4>
+
+<p>
+  The backup service configuration allows you to specify what files to include or exclude from
+  backup. The syntax for the data backup configuration xml file is as follows:
+</p>
+
+<pre>
+&lt;full-backup-content&gt;
+    &lt;include domain=["file" | "database" | "sharedpref" | "external" | "root"] path="string" /&gt;
+    &lt;exclude domain=["file" | "database" | "sharedpref" | "external" | "root"] path="string" /&gt;
+&lt;/full-backup-content&gt;
+</pre>
+
+<p>
+  The following elements and attributes allow you to specify the files to include and exclude from
+  backup:
+</p>
+
+<ul>
+  <li>
+	<code>&lt;include&gt;</code>. Use this element if you want to specify a set of resources to
+	back up, instead of having the system back up all data in your app by default. When you specify
+	an <code>&lt;include&gt;</code> tag, the system backs up only the resources specified with this
+	element.
+  </li>
+
+  <li>
+	<code>&lt;exclude&gt;</code>. Use this element to specify a set of resources to exclude from
+	backup. The system backs up all data in your app, except for resources specified with this
+	element.
+  </li>
+
+  <li>
+	<code>domain.</code> The type of resource you want to include or exclude from backup. The valid
+	values you can specify for this attribute include:
+  </li>
+
+  <li style="list-style: none">
+	<ul>
+	  <li>
+		<code>root</code>. Specifies that the resource is in the app’s root directory.
+	  </li>
+
+	  <li>
+		<code>file</code>. Corresponds to a resource in the directory returned by the
+		<code><a href="{@docRoot}reference/android/content/Context.html#getFilesDir()">getFilesDir()</a></code>
+		method.
+	  </li>
+
+	  <li>
+		<code>database</code>. Corresponds to a database returned by the <code><a href=
+		"{@docRoot}reference/android/content/Context.html#getDatabasePath(java.lang.String)">getDatabasePath()</a></code>
+		method or by using the <code><a href=
+		"{@docRoot}reference/android/database/sqlite/SQLiteOpenHelper.html">SQLiteOpenHelper</a></code>
+		class.
+	  </li>
+
+	  <li>
+		<code>sharedpref</code>. Corresponds to a <code><a href=
+		"{@docRoot}reference/android/content/SharedPreferences.html">SharedPreferences</a></code>
+		object returned by the <code><a href=
+		"{@docRoot}reference/android/content/Context.html#getSharedPreferences(java.lang.String,%20int)">
+		getSharedPreferences()</a></code> method.
+	  </li>
+
+	  <li>
+		<code>external</code>. Specifies that the resource is in external storage, and corresponds
+		to a file in the directory returned by the <code><a href=
+		"{@docRoot}reference/android/content/Context.html#getExternalFilesDir(java.lang.String)">getExternalFilesDir()</a></code>
+		method.
+	  </li>
+
+	  <li>
+		<code>path</code>. The file path to a resource that you want to include or exclude from
+		backup.
+	  </li>
+	</ul>
+  </li>
+</ul>
+
+
+<h3>Prohibiting Data Backups</h3>
+
+<p>
+  You can choose to prevent automatic backups of any of your app data by setting the
+  <code>android:allowBackup</code> attribute to <code>false</code> in the application element of
+  your manifest. This setting is illustrated in the following example code:
+</p>
+
+<pre>
+&lt;?xml version="1.0" encoding="utf-8"?&gt;
+&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
+        xmlns:tools="http://schemas.android.com/tools"
+        package="com.my.appexample"&gt;
+    &lt;uses-sdk android:minSdkVersion="9"/&gt;
+    &lt;uses-sdk android:targetSdkVersion="android-MNC"/&gt;
+    &lt;application ...
+<strong>        android:allowBackup="false"&gt;</strong>
+    &lt;/application&gt;
+    ...
+&lt;/manifest&gt;
+</pre>
+
+
+<h2>Testing Backup Configuration</h2>
+
+<p>
+  Once you have created a backup configuration, you should test it to make sure your app saves data
+  and can be restored properly.
+</p>
+
+
+<h4>Enabling Backup Logging</h4>
+
+<p>
+  To help determine how the backup feature is parsing your XML file, enable logging before
+  performing a test backup:
+</p>
+
+<pre>$ adb shell setprop log.tag.BackupXmlParserLogging VERBOSE</pre>
+
+<h4>Testing Backup</h4>
+
+<p>
+  To manually enable a backup, call the following command, specifying the package name for your app
+  as the <code>&lt;PACKAGE&gt;</code> parameter:
+</p>
+
+<pre>$ adb shell bmgr fullbackup &lt;PACKAGE&gt;</pre>
+
+<h4>Testing Restore</h4>
+<p>
+  To manually initiate a restore after your app data is backed-up, call the following command,
+  specifying the package name for your app as the <code>&lt;PACKAGE&gt;</code> parameter:
+</p>
+
+<pre>$ adb shell bmgr restore &lt;PACKAGE&gt;</pre>
+
+<p class="warning">
+  <b>Warning:</b> This action stops your app and wipes its data before performing the restore
+  operation.
+</p>
+
+<p>
+  You initiate the restore process for your app by uninstalling and reinstalling your app. The app
+  data is automatically restored from the cloud once the app installation is complete.
+</p>
+
+
+<h4>Troubleshooting Backups</h4>
+
+<p>
+  If you run into issues, clear the backup data and associated metadata by calling this command.
+</p>
+
+<pre>$ adb shell bmgr wipe &lt;TRANSPORT&gt; &lt;PACKAGE&gt;</pre>
+
+<p>
+  The <code>&lt;TRANSPORT&gt;</code> value must be prefixed by <code>com.google.android.gms</code>.
+  To get the list of transports, call the following command:
+</p>
+
+<pre>$ adb shell bmgr list transports</pre>
+
+<h2>Known Issues</h2>
+
+<p>The following are known issues with the automatic backup service:</p>
+
+<ul>
+  <li>For apps that use Google Cloud Messaging for push notifications, there is a known issue where
+  backing up the registration id returned by Google Cloud Messaging registration can break push
+  notifications for the restored application. It is important to query the API for a new
+  registration id after being installed on a new device - which will not be the case if the old
+  registration id was backed up. To avoid this, exclude the registration id from the set of backed
+  up files.
+  </li>
+</ul>

+page.title=Android M Preview Runtime Permissions
+
+@jd:body
+
+
+<p>
+  The M Developer Preview introduces a new app permissions model which makes it
+  less frustrating for users to install and upgrade apps. If an app running on
+  M supports the new permissions model, the user does not have to grant any
+  permissions when they install or upgrade the app. Instead, the app requests
+  permissions as they are needed, and the system shows a dialog to the user
+  asking for the permission.
+</p>
+
+<p>
+  If an app supports the new permissions model, it can still be installed and
+  run on devices running older versions of Android, using the old permissions
+  model on those devices.
+</p>
+
+<h2>
+  Overview
+</h2>
+
+<p>
+  If an app's target SDK version is the M developer preview, that indicates
+  that the app uses the new permissions model:
+</p>
+
+<ul>
+  <li>Permissions are divided into <em>permission groups</em>, based on their
+  functionality. For example, all permissions relating to the camera and photo
+  roll are grouped in the Camera permission group,
+  [link]android.permission-group.CAMERA[/link].
+  </li>
+
+  <li>The app declares all the permissions it needs in the manifest, as in
+  earlier Android platforms.
+  </li>
+
+  <li>When the user installs or updates the app, the app is granted just those
+  permissions it requests that fall under <a href=
+  "https://android-preview.googleplex.com/reference/android/content/pm/PermissionInfo.html#PROTECTION_NORMAL">
+    <code>PROTECTION_NORMAL</code></a>, as well as signature and system permissions, as
+    described below. The user is <em>not</em> prompted to grant any permissions
+    at this time.
+  </li>
+
+  <li>When the app needs to perform any action that requires a permission, it
+  first checks whether it has that permission already. If it does not, it
+  requests to be granted that permission.
+  </li>
+
+  <li>When the app requests a permission, the system shows a dialog box to the
+  user, then calls the app's callback function to notify it whether the
+  permission was granted. If a user grants a permission, the app is given all
+  permissions in that permission's functional area that were declared in the
+  app manifest.
+  </li>
+
+  <li>If the app is not granted an appropriate permission, it should handle the
+  failure cleanly. For example, if the permission is just needed for an added
+  feature, the app can disable that feature. If the permission is essential for
+  the app to function, the app might disable all its functionality and inform
+  the user that they need to grant that permission.
+  </li>
+
+  <li>Users can always go to the app's <b>Settings</b> screen and turn on or
+  off any of the app's permissions.
+  <!-- insert screenshot of settings screen-->
+  If a user turns off an app's permissions, the app is
+  <em>not</em> notified.
+  </li>
+</ul>
+
+<h3>
+  System Apps and Signature Permissions
+</h3>
+
+<p>
+  Ordinarily, an app is just granted the <a href=
+  "https://android-preview.googleplex.com/reference/android/content/pm/PermissionInfo.html#PROTECTION_NORMAL">
+  <code>PROTECTION_NORMAL</code></a> permissions when it is installed. However,
+  under some circumstances the app is granted more permissions:
+</p>
+
+<ul>
+  <li>If an app is part of the system image, it is automatically granted all
+  the permissions listed in its manifest.
+  </li>
+
+  <li>Apps are granted all permissions listed in the manifest that fall under
+  <a href=
+  "https://android-preview.googleplex.com/reference/android/content/pm/PermissionInfo.html#PROTECTION_SIGNATURE">
+    PROTECTION_SIGNATURE</a>, if the app's signature matches the signature of
+    the app that declares the permissions.
+  </li>
+</ul>
+
+<p>
+  In both cases, the user can still revoke permissions at any time by going to
+  the app's <b>Settings</b> screen, so the app should continue to check for
+  permissions at run time and request them if necessary.
+</p>
+
+<h3>
+  Forwards and Backwards Compatibility
+</h3>
+
+<p>
+  If an app does not target the M developer preview, it continues to use the
+  old permissions model even on M devices. When the app is installed, the
+  system asks the user to grant all permissions listed in the app's manifest.
+</p>
+
+<p>
+  If an app using the new permissions model is run on a pre-M device, the
+  system treats it the same as any other app. Once again, the system asks the
+  user to grant all declared permissions at install time.
+</p>
+
+<h2 id="">Coding for Runtime Permissions</h2>
+
+<p>
+  If your app targets the new M Developer Preview, you must use the new
+  permissions model. This means that in addition to declaring your needed
+  permissions in the manifest, you must also check to see if you have the
+  permissions at run time, and request the permissions if you do not already
+  have them.
+</p>
+
+<h3>
+  Enabling the New Permissions Model
+</h3>
+
+<p>
+  To enable the new M Developer Preview permissions model, set the app's
+  <a href=
+  "http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#target">
+  targetSdkVersion</a> attribute to "M". Doing this enables all the new
+  permissions features.
+</p>
+
+<!-- TODO: Insert manifest snippet -->
+
+<h3>
+  Designating a Permission for M Only
+</h3>
+
+<p>
+  You can use the new <code>&lt;uses-permission-sdk-m&gt;</code> element in the
+  app manifest to indicate that a permission is only needed on the M platform.
+  If you declare a permission this way, then whenever the app is installed on
+  an older device, the user is not prompted to grant the permission and the
+  permission is not granted to the app. This allows you to add new permissions
+  to updated versions of your app without forcing users to grant permissions
+  when they install the update.
+</p>
+
+<p>
+  If the app is running on a device with the M developer preview,
+  <code>&lt;uses-permission-sdk-m&gt;</code> behaves the same as
+  <code>&lt;uses-permission&gt;</code>. The user is not prompted to grant any
+  permissions when the app is installed, and the app requests permissions as
+  they are needed.
+</p>
+
+<h3 id="prompting">
+  Prompting for Permissions on the M Preview
+</h3>
+
+<p>
+  If your app uses the new M Developer Preview permissions model, the user is
+  not asked to grant all permissions when the app is first launched on a device
+  running the M Preview. Instead, your app requests permissions as they are
+  needed. When your app requests a permission, the system shows a dialog to the
+  user.
+</p>
+
+<p>
+  An app should follow this workflow to request permissions on an Android M
+  device. The device can check what platform it's running on by checking the
+  value of {@link android.os.Build.VERSION#SDK_INT Build.VERSION.SDK_INT}. If
+  the device is running the M Developer Preview, {@link
+  android.os.Build.VERSION#SDK_INT SDK_INT} is 23.
+  <!-- TODO: Confirm this number -->
+</p>
+<ol>
+  <li>When the user tries to do something that requires a permission, the app
+  checks to see if it currently has permission to perform this operation. To do
+  this, the app calls
+   <a href="https://android-preview.googleplex.com/reference/android/content/Context.html#checkSelfPermission(java.lang.String)"><code>Context.CheckSelfPermission(<em>permission_name</em>)</code></a> . The
+  app should do this even if it knows the user has already granted that
+  permission, since the user can revoke an app's permissions at any time. For
+  example, if a user wants to use an app to take a picture, the app calls
+  <a href="https://android-preview.googleplex.com/reference/android/content/Context.html#checkSelfPermission(java.lang.String)"><code>Context.CheckSelfPermission(Manifest.permission.CAMERA)</code></a>.
+  </li>
+
+<!-- TODO: Full list of permissions (or link to that list),
+  and how they break down by functional area]-->
+
+  <li>If the permission is not already granted to the app, the app calls
+  <a href=
+  "https://android-preview.googleplex.com/reference/android/app/Activity.html#requestPermissions(java.lang.String[],%20int)">
+    <code>requestPermissions()</code></a> to request the
+    appropriate permission or permissions. This method functions
+    asynchronously.
+    <!-- TODO: insert code snippet showing permission check and request -->
+  </li>
+
+  <li>The system presents a dialog box to the user.
+  <!-- TODO: insert screenshot of permissions dialog box -->
+    When the user responds, the system calls <a href=
+    "https://android-preview.googleplex.com/reference/android/app/Activity.html#onRequestPermissionsResult(int,%20java.lang.String[],%20int[])">
+    <code>Activity.onRequestPermissionsResult()</code></a> with the
+    results; your app needs to override that method. The callback is passed the
+    same request code you passed to <a href=
+    "https://android-preview.googleplex.com/reference/android/app/Activity.html#requestPermissions(java.lang.String[],%20int)">
+    <code>requestPermissions()</code></a>.
+    <!-- TODO: Insert code snippet of callback method -->
+  </li>
+
+  <li>If the user grants a permission, the app is given all permissions
+  in that functional area that are listed in the app manifest.
+  If the request is denied, you should take appropriate action. For
+  example, you might disable any menu actions that depend on this permission.
+  </li>
+</ul>
+
+<p>
+  When the system asks the user to grant a permission, the user has the option
+  of telling the system not to ask for that permission again. In that case,
+  when an app asks for that permission with <a href=
+    "https://android-preview.googleplex.com/reference/android/app/Activity.html#requestPermissions(java.lang.String[],%20int)">
+    <code>requestPermissions()</code></a>, the
+  system immediately denies the request. For this reason, your app cannot
+  assume that any direct interaction with the user has taken place.
+</p>
+
+<p>
+  If your app runs on a device that has SDK 22 or lower, the app uses the old
+  permissions model. When the user installs the app, they are prompted to grant
+  all the permissions your app requests in its manifest, except for those
+  permissions which are labeled with <code>&lt;uses-permission-sdk-m&gt;</code>.
+</p>
+
+<h2 id="">Best Practices</h2>
+
+<p>
+  The new permissions model gives users a smoother experience, and makes it
+  easier for them to install apps and feel comfortable with what the apps are
+  doing. We recommend the following best practices to take full advantage of
+  the new model.
+</p>
+
+<h3>
+  Don't Overwhelm the User
+</h3>
+
+<p>
+  If you confront the user with a lot of permissions requests at once, you may
+  overwhelm the user and cause them to quit your app. Instead, you should ask
+  for permissions as you need them.
+</p>
+
+<p>
+  In some cases, one or more permissions might be absolutely essential to your
+  app. In that case, it might make sense to ask for all the permissions as soon
+  as the app launches.
+  <!-- TODO: insert screenshot of dialog box asking for several permissions -->
+  For example, if you make a photography app, the app would
+  need access to the device camera. When the user launches the app for the
+  first time, they won't be surprised to be asked to give permission to use the
+  camera. But if the same app also had a feature to share photos with the
+  user's contacts, you probably should <em>not</em> ask for that permission at
+  first launch. Instead, wait until the user tries to use the "sharing" feature
+  and ask for the permission then.
+</p>
+
+<p>
+  If your app provides a tutorial, it may make sense to request app's essential
+  permissions at the end of the tutorial sequence.
+</p>
+
+<h3>
+  Explain Why You Need Permissions
+</h3>
+
+<p>
+  The permissions screen shown by the system when you call <a href=
+  "https://android-preview.googleplex.com/reference/android/app/Activity.html#requestPermissions(java.lang.String[],%20int)">
+  <code>requestPermissions()</code></a> says what permission your app wants,
+  but doesn't say why you want it. In some cases, the user may find that
+  puzzling. It's a good idea to explain to the user why your app wants the
+  permissions before you call <a href=
+  "https://android-preview.googleplex.com/reference/android/app/Activity.html#requestPermissions(java.lang.String[],%20int)">
+  <code>requestPermissions()</code></a>.
+</p>
+
+<p>
+  For example, a photography app might want to use location services, so it can
+  geotag the photos. A typical user might not understand that a photo can
+  contain location information, and would be puzzled why their photography app
+  wanted to know the location. So in this case, it's a good idea for the app to
+  tell the user about this feature <em>before</em> calling
+  <a href=
+  "https://android-preview.googleplex.com/reference/android/app/Activity.html#requestPermissions(java.lang.String[],%20int)">
+  <code>requestPermissions()</code></a>.
+</p>
+
+<p>
+  As noted, one way to do this is to incorporate these requests into an app
+  tutorial. The tutorial can show each of the app's features in turn, and as it
+  does this, it can explain what permissions are needed. For example, the
+  photography app's tutorial demonstrate its "share photos with your contacts"
+  feature, then tell the user that they'll need to give permission for the app
+  to see the user's contacts, and <em>then</em> call <a href=
+  "https://android-preview.googleplex.com/reference/android/app/Activity.html#requestPermissions(java.lang.String[],%20int)">
+  <code>requestPermissions()</code></a>
+  to get that access. Of course, some users will want to skip the tutorial, so
+  you'll still need to check for and request permissions during the app's
+  normal operation.
+</p>
+
+<h3>
+  Opt Out If Necessary
+</h3>
+
+<p>
+  Until you are ready to use the new permissions model, you can opt out simply
+  by setting your app's <a href=
+  "http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#target">
+  targetSdkVersion</a> to 22 or less. If you do this, the system will use the
+  old permissions model. When the user downloads the app, they will be prompted
+  to grant all the permissions listed in the manifest.
+</p>
+
+<p>
+  With the M Developer Preview, users can turn off permissions for <em>any</em>
+  app from the app's Settings page, regardless of what SDK version the app
+  targets. For this reason, it's a good idea to follow the steps described in
+  <a href="#prompting">"Prompting for Permissions on the M Preview"</a> even if
+  your app doesn't fully support the new permissions model.
+</p>
+
+<p class="note">
+  <strong>Note:</strong> If a user turns off permissions for a legacy app, the system
+  silently disables the appropriate functionality. When the app attempts to
+  perform an operation that requires that permission, the operation will not
+  necessarily cause an exception. Instead, it might return an empty data set or
+  otherwise signal an error.
+</p>

-
-<p>Advertising is one of the means to monetize (make money with) mobile applications.  In this
-lesson, you are going to learn how to incorporate banner ads in your Android application.</p>
-
-<p>While this lesson and the sample application use <a
-href="http://code.google.com/mobile/ads/">AdMob</a> to serve ads, the Android platform doesn’t
-impose any restrictions on the choice of mobile advertising network.  To the extent possible, this
-lesson generically highlights concepts that are similar across advertising networks.</p>
-
-<p>For example, each advertising network may have some network-specific configuration settings such
-as geo-targeting and ad-text font size, which may be configurable on some networks but not on
-others.  This lesson does not touch not these topics in depth and you should consult documentation
-provided by the network you choose.</p>
-
-
-<h2 id="ObtainPubAccountAndSDK">Obtain a Publisher Account and Ad SDK</h2>
-
-<p>In order to integrate advertisements in your application, you first must become a publisher by
-registering a publishing account with the mobile advertising network.  Typically, an identifier is
-provisioned for each application serving advertisements.  This is how the advertising network
-correlates advertisements served in applications.  In the case of AdMob, the identifier is known as
-the Publisher ID.  You should consult your advertising networks for details.</p>
-
-<p>Mobile advertising networks typically distribute a specific Android SDK, which consists of code
-that takes care of communication, ad refresh, look-and-feel customization, and so on.</p>
-
-<p>Most advertising networks distribute their SDK as a JAR file.  Setting up ad network JAR file in
-your Android project is no different from integrating any third-party JAR files.  First, copy the
-JAR files to the <code>libs/</code> directory of your project.  If you’re using Eclipse as IDE, be
-sure to add the JAR file to the Build Path.  It can be done through <b>Properties &gt;
-Java Build Path &gt; Libraries &gt; Add JARs</b>.</p>

-</p>
-
-
-<h2 id="DeclarePermissions">Declare Proper Permissions</h2>
-
-<p>Because the mobile ads are fetched over the network, mobile advertising SDKs usually
-require the declaration of related permissions in the Android manifest.  Other kinds of permissions
-may also be required.</p>
-
-<p>For example, here's how you can request the {@link android.Manifest.permission#INTERNET}
-permission:</p>
-
-<pre>
-&lt;/manifest&gt;
-    &lt;uses-permission android:name=&quot;android.permission.INTERNET&quot; /&gt;
-    ...
-    &lt;application&gt;...&lt;/application&gt;

-<p class="img-caption">
-    <strong>Figure 2.</strong> Screenshot of the ad layout in the Mobile Ads sample.
-</p>
-</div>
-
-<p>Banner ads typically are implemented as a custom {@link android.webkit.WebView} (a view for
-viewing web pages). Ads also come in different dimensions and shapes.  Once you’ve decided to put an
-ad on a particular screen, you can add it in your activity's XML layout.  The XML snippet below
-illustrates a banner ad displayed on top of a screen.</p>
-
-<pre>
-&lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
-        android:id=&quot;&#064;+id/ad_catalog_layout&quot;
-        android:orientation=&quot;vertical&quot;
-        android:layout_width=&quot;match_parent&quot;
-        android:layout_height=&quot;match_parent&quot; &gt;
-    &lt;com.google.ads.AdView
-        xmlns:googleads=&quot;http://schemas.android.com/apk/lib/com.google.ads&quot;
-        android:id=&quot;&#064;+id/ad&quot;
-        android:layout_width=&quot;fill_parent&quot;
-        android:layout_height=&quot;wrap_content&quot;
-        googleads:adSize=&quot;BANNER&quot;
-        googleads:adUnitId=&quot;&#064;string/admob_id&quot; /&gt;
-    &lt;TextView android:id=&quot;&#064;+id/title&quot;
-        android:layout_width=&quot;match_parent&quot;
-        android:layout_height=&quot;wrap_content&quot;
-        android:text=&quot;&#064;string/banner_top&quot; /&gt;
-    &lt;TextView android:id=&quot;&#064;+id/status&quot;
-        android:layout_width=&quot;match_parent&quot;
-        android:layout_height=&quot;wrap_content&quot; /&gt;
-&lt;/LinearLayout&gt;
-</pre>
-
-<p>You should consider using alternative ad sizes based on various configurations such as screen
-size or screen orientation.  This can easily be addressed by <a
-href="{@docRoot}guide/topics/resources/providing-resources.html#AlternativeResources">providing
-alternative resources</a>. For instance, the above sample layout might placed under the
-<code>res/layout/</code> directory as the default layout. If larger ad
-sizes are available, you can consider using them for "large" (and above) screens. For example, the
-following snippet comes from a layout file in the <code>res/layout-large/</code> directory, which
-renders a larger ad for "large" screen sizes.</p>
-
-<pre>
-...
-&lt;com.google.ads.AdView
-    xmlns:googleads=&quot;http://schemas.android.com/apk/lib/com.google.ads&quot;
-    android:id=&quot;&#064;+id/ad&quot;
-    android:layout_width=&quot;fill_parent&quot;
-    android:layout_height=&quot;wrap_content&quot;
-    <strong>googleads:adSize=&quot;IAB_LEADERBOARD&quot;</strong>
-    googleads:adUnitId=&quot;&#064;string/admob_id&quot; /&gt;
-...
-</pre>
-
-<p>Notice that the custom view name and it’s configuration attributes are network-specific.  Ad
-networks might support configurations with XML layout attributes (as shown above), runtime APIs, or
-both. In the sample application, Mobile Ads, the {@code AdView} ad size
-(<code>googleads:adSize</code>) and publisher ID (<code>googleads:adUnitId</code>) are set up in the
-XML layout.</p>
-
-<p>When deciding where to place ads within your application, you should carefully
-consider user-experience.  For example, you don’t want to fill the screen with
-multiple ads that will quite likely annoy your users.  In fact, this practice is banned by some ad
-networks. Also, avoid placing ads too closely to UI controls to avoid inadvertent clicks.</p>
-
-<p>Figures 3 and 4 illustrate what <strong>not</strong> to do.</p>
-
-<div style="float:left;width:275px">
-<img src="/images/training/ads-close-to-button.png" />
-<p class="img-caption">
-    <strong>Figure 3.</strong> Avoid putting UI

-    <strong>Figure 4.</strong> Don't overlay ad banner on useful content.
-</p>
-</div>
-
-
-<h2 id="InitializeAd" style="clear:left">Initialize the Ad</h2>
-
-<p>After setting up the ad in the XML layout, you can further customize the ad in {@link
-android.app.Activity#onCreate Activity.onCreate()} or {@link
-android.app.Fragment#onCreateView Fragment.onCreateView()} based on how your application is
-architected. Depending on the ad network, possible configuration parameters are: ad size, font
-color, keyword, demographics, location targeting, and so on.</p>
-
-<p>It is important to respect user privacy if certain parameters, such as demographics or location,
-are passed to ad networks for targeting purposes.  Let your users know and give them a chance to opt
-out of these features.</p>
-
-<p>In the below code snippet, keyword targeting is used.  After the keywords are set, the
-application calls <code>loadAd()</code> to begin serving ads.</p>
-
-<pre>
-public View onCreateView(LayoutInflater inflater, ViewGroup container,
-        Bundle savedInstanceState) {
-    ...
-    View v = inflater.inflate(R.layout.main, container, false);
-    mAdStatus = (TextView) v.findViewById(R.id.status);
-    mAdView = (AdView) v.findViewById(R.id.ad);
-    mAdView.setAdListener(new MyAdListener());
-
-    AdRequest adRequest = new AdRequest();
-    adRequest.addKeyword("sporting goods");
-    mAdView.loadAd(adRequest);
-    return v;
-}
-</pre>
-
-
-
-<h2 id="EnableTestMode">Enable Test Mode</h2>
-
-<p>Some ad networks provide a test mode.  This is useful during development and testing in which ad
-impressions and clicks are not counted.</p>
-
-<p class="caution"><strong>Important:</strong> Be sure to turn off test mode before publishing your
-application.</p>
-
-
-<h2 id="ImplementListeners">Implement Ad Event Listeners</h2>
-
-<p>Where available, you should consider implementing ad event listeners, which provide callbacks on
-various ad-serving events associated with the ad view.  Depending on the ad network, the listener
-might provide notifications on events such as before the ad is loaded, after the ad is loaded,
-whether the ad fails to load, or other events.  You can choose to react to these events based on
-your specific situation.  For example, if the ad fails to load, you can display a custom banner
-within the application or create a layout such that the rest of content fills up the screen.</p>
-
-<p>For example, here are some event callbacks available from AdMob's {@code AdListener}
-interface:</p>
-
-<pre>
-private class MyAdListener implements AdListener {
-    ...
-
-    &#064;Override
-    public void onFailedToReceiveAd(Ad ad, ErrorCode errorCode) {
-        mAdStatus.setText(R.string.error_receive_ad);
-    }
-
-    &#064;Override
-    public void onReceiveAd(Ad ad) {
-        mAdStatus.setText("");
-    }
-}
-</pre>

-<p>Apart from offering paid apps, there are a number of other ways to monetize your mobile applications.  In this class, we are going to examine a number of typical methods (more lessons are to come) and their associated technical best practices.  Obviously, each application is different and you should experiment with different combinations of these and other monetization methods to determine what works best for you.</p>

+  The Google+ platform for Android lets you authenticate a user with the same credentials they use
+  on Google every day. Once a user signs in with Google, you can create more engaging experiences
+  and drive usage of your app.
+</p>
+
+<p>
+  The <a href="https://developers.google.com/+/mobile/android/">Google+ Android API</a> allows
+  you to integrate sign-in and social features into your app.
+</p>
+
+
+<h2 id="features">Key Developer Features</h2>
+
+<h4>Trusted authentication</h4>
+<p>
+  Google+ Sign-In is a simple, trusted, and secure way to let people sign in to your app with their
+  Google credentials and bring along their Google+ info.<br>
+  <a href="https://developers.google.com/+/mobile/android/sign-in" class="external-link">Add
+  sign-in</a>.
+</p>
+
+<h4>Access the profile and social graph</h4>
+<p>
+  Once users have signed in with Google, your app can welcome them by name, display their picture,
+  connect them with friends, and lots more.<br>
+  <a href="https://developers.google.com/+/mobile/android/people" class="external-link">Access the
+  social graph</a>.
+</p>
+
+<h4>Stand out in the stream</h4>
+<p>
+  Interactive posts is a rich way of sharing to Google+. It lets users prompt friends to take
+  specific actions in your app from a Google+ post, like "listen," "RSVP," "check-in," and over 100
+  more actions.<br>
+  <a class="external-link" href="https://developers.google.com/+/mobile/android/share">Post
+  interactive content</a>.
+</p>
+
+<h4>Recommend content</h4>
+<p>
+  Add a native +1 button so users can recommend content from your app. These endorsements can give
+  your app more credibility and help it grow faster.<br>

+<h2 id="start">Get Started</h2>
+<p>
+  The Google+ Android APIs are part of the Google Play services platform. To use Google+ features,
+  set up the Google Play services SDK in your app development project. For more information, see
