-<h2 id="msg-lifetime">Lifetime of a Message</h2>
-<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>
-
-<h2 id="throttling">Throttling</h2>
-<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>
-
-<h2 id="reg-state">Keeping the Registration State in Sync</h2>
-<p>Whenever the application 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, it should try again or unregister from GCM.</p>
-
-<p>There are also two other scenarios that require special care:</p>
-<ul>
-  <li>Application update</li>
-  <li>Backup and restore
-  </li>
-</ul>
-<p>When an application is updated, it should invalidate its existing registration
-ID, as it is not guaranteed to work with the new version.  Because there is no
-lifecycle method called when the application is updated, the best way to achieve
-this validation is by storing the current application version when a registration
-ID is stored. Then when the application is started, compare the stored value with
-the current application version. If they do not match, invalidate the stored data
-and start the registration process again.</p>
-
-<p>Similarly, you should not save the registration ID when an application is
-backed up. This is because the registration ID could become invalid by the time
-the application is restored, which would put the application in an invalid state
-(that is, the application thinks it is registered, but the server and GCM do not
-store that registration ID anymore&mdash;thus the application will not get more
-messages).</p>
-<h3 id="canonical">Canonical IDs</h3>
-<p>On the server side, as long as the application is behaving well, everything
-should work normally. However, if a bug in the application 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 application. 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>
-
-<h2 id="retry">Automatic Retry Using Exponential Back-Off</h2>
-
-<p>When registration or unregistration fails, the app should retry the failed operation.</p>
-<p>In the simplest case, if your application attempts to register and GCM is not a
-fundamental part of the application, the application 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. If the register (or unregister) operation was synchronous, it could be retried
-in a simple loop. However, since it is asynchronous, the best approach is to schedule
-a {@link android.app.PendingIntent} to retry the operation.
-
-<h2 id="unreg">Unregistration</h2>
-
-<p>This section explains when you should unregister in GCM and what happens
-when you do.</p>
-
-<h3 id="unreg-why">Why you should rarely unregister</h3>
-
-<p>A registration ID (regID) represents a particular Android application running
-on a particular device. 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 regID has
-been compromised. In general, though, once an app has a regID, 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 regID maps an app to a device. It 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>The solution is to manage your own mapping between users, the regID, and
-individual messages:</p>
-
-<ul>
-  <li>Your app server should maintain a mapping between the current user
-and the regID. This should include information about which user is supposed to
-receive a particular message.</li>
-  <li>The app running on the device should check to ensure that messages it
-receives match the logged in user.</li>
-</ul>
-
-
-<h3 id="unreg-how">How unregistration works</h3>
-
-<p>An application can be automatically unregistered after it is uninstalled from
-the device. However, this process does not happens right away, as Android does not
-provide an uninstall callback. What happens in this scenario is as follows:</p>
-<ol>
-  <li>The end user uninstalls the application.</li>
-  <li>The 3rd-party server sends a message to GCM server.</li>
-  <li>The GCM server sends the message to the device.</li>
-  <li>The GCM client receives the message and queries Package Manager about
-whether there are broadcast receivers configured to receive it, which returns
-<code>false</code>.
-</li>
-  <li>The GCM client informs the GCM server that the application was uninstalled.</li>
-  <li>The GCM server marks the registration ID for deletion.</li>
-  <li>The 3rd-party server sends a message to  GCM.</li>
-  <li>The GCM returns a <code>NotRegistered</code> error message to the 3rd-party server.</li>
-  <li>The 3rd-party deletes the registration ID.
-  </li>
-</ol>
-
-<p class ="note"><strong>Note:</strong> The GCM client is the Google Cloud
-Messaging framework present on the device.</p>
-
-<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 device.
-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 application is
-being developed and tested).</p>
-
-<h2 id="collapsible">Send-to-Sync  vs. Messages with Payload</h2>
-
-<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). These concepts are described in more
-detail in the following sections.</p>
-
-<h3 id="s2s">Send-to-sync messages</h3>
-
-<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, so it makes sense to have each new
-message replace the preceding message. </p>
-
-<p>The email and sports applications are cases where you would probably use the
-GCM <code>collapse_key</code> parameter. A <em>collapse key</em> is an arbitrary
-string that is used to collapse a group of like messages when the device is offline,
-so that only the most recent message gets sent to the client. For example,
-&quot;New mail,&quot; &quot;Updates available,&quot; and so on</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. The message is delivered through a regular
-<code>com.google.android.c2dm.intent.RECEIVE</code> intent with the
-extra <code>message_type</code>, for which the value is always the string
-&quot;deleted_messages&quot;.</p>
-
-<p>The application should respond by syncing with the server to recover the
-discarded messages. </p>
-
-<h3 id="which">Which should I use?</h3>
-  <p>If your application does not need to use non-collapsible messages, collapsible
-messages are a better choice from a performance standpoint, because they put less
-of a burden on the device battery. 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 device at any given time</strong>. You must not exceed this number, or it could cause
-unpredictable consequences.</p>
-
-<h2 dir="ltr" id="ttl">Setting an Expiration Date for a Message</h2>
-<p>The Time to Live (TTL) feature lets  the sender  specify the maximum lifespan
-of a message using the <code>time_to_live</code> parameter in the send request.
-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>
-<h3 id="bg">Background </h3>
-<p>GCM will usually deliver messages immediately after they are sent. However,
-this might not always be possible. For example, the device could be turned off,
-offline, or otherwise unavailable. In other cases, 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>
-
-
-<h2 id="multi-senders">Receiving Messages from Multiple Senders</h2>
-
-<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>This code snippet illustrates this feature. Senders are passed as an intent
-extra in a comma-separated list:</p>
-
-<pre class="prettyprint pretty-java">Intent intent = new Intent(GCMConstants.INTENT_TO_GCM_REGISTRATION);
-intent.setPackage(GSF_PACKAGE);
-intent.putExtra(GCMConstants.EXTRA_APPLICATION_PENDING_INTENT,
-        PendingIntent.getBroadcast(context, 0, new Intent(), 0));
-String senderIds = &quot;968350041068,652183961211&quot;;
-intent.putExtra(GCMConstants.EXTRA_SENDER, senderIds);
-ontext.startService(intent);
- </pre>
-
-<p>Note that there is limit of 100 multiple senders.</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! The only change required in the application is replacing the email account passed in the sender parameter of the registration intent with the project number generated when signing up for the new service. For example:</p>
-<pre class="prettyprint pretty-java">Intent registrationIntent = new Intent(&quot;com.google.android.c2dm.intent.REGISTER&quot;);
-// sets the app name in the intent

+
 <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>

-<p>These processes are described in more detail below.</p>
+</li>
 
-<h3 id="register">Enable GCM</h3>
 
-<p>The first time the Android application needs to use the messaging service, it
-calls the <a href="{@docRoot}reference/com/google/android/gms/gcm/GoogleCloudMessaging.html">
-{@code GoogleCloudMessaging}</a> method {@code register()}, as discussed in
-<a href="client.html">Implementing GCM Client</a>.
-The {@code register()} method returns a registration ID. The Android
-application should store this ID for later use (for instance,
-to check in <code>onCreate()</code> if it is already registered).
+</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="push-process">Send a message</h3>
+<h3 id="unreg">Unregistration</h3>
 
-<p>Here is the sequence of events that occurs when the application server sends a 
-message:</p>
+<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>An 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 application server sends a  message to  GCM servers.</li>
-  <li>Google enqueues and stores the message in case the device is
-offline.</li>
-  <li>When the device is online, Google sends the message to the device. </li>
-  <li>On the device, the system  broadcasts the  message to the specified
-Android application via Intent broadcast with proper permissions, so that only the
-targeted Android application gets the message. This wakes the Android application up. The
-Android application does not need to be running beforehand to receive the message.</li>
-  <li>The Android application processes the message. If the Android application is doing
-non-trivial processing, you may want to grab a
-{@link android.os.PowerManager.WakeLock} and do any processing in a service.</li>
+  <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> An Android application can  unregister GCM if it no longer wants to receive 
-messages.</p>
-
-<h3 id="receiving">Receive a message</h3>
-
-<p>This is the sequence of events that occurs when an Android application
-installed on a mobile device receives a message:</p>
-
-<ol>
-  <li>The system receives the incoming message and extracts the raw key/value
-pairs from the message payload, if any.</li>
-  <li>The system passes the key/value pairs to the targeted Android application
-in a <code>com.google.android.c2dm.intent.RECEIVE</code> Intent as a set of
-extras.</li>
-  <li>The Android application extracts the raw data
-from the <code>com.google.android.c2dm.intent.RECEIVE</code><code> </code>Intent
-by key and processes the data.</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>

-server sends a message:</p>
+server sends a message (the details vary depending on the platform):</p>
 <ol>
-  <li>The application server sends a message to GCM servers.</li>
-  <li>Google enqueues and stores the message in case the device is offline.</li>
-  <li>When the device is online, Google sends the message to the device.</li>
-  <li>On the device, the system broadcasts the message to the specified Android
-application via Intent broadcast with proper permissions, so that only the targeted
-Android application gets the message. This wakes the Android application up.
-The Android application does not need to be running beforehand to receive the message.</li>

-<h2 id="receive">Receiving Messages</h2>
+<h3 id="collapsible">Send-to-Sync  vs. Messages with Payload</h3>
 
-<p>This is the sequence of events that occurs when an Android application
-installed on a mobile device receives a message:</p>
+<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>
 
-<ol>
-  <li>The system receives the incoming message and extracts the raw key/value
-pairs from the message payload, if any.</li>
-  <li>The system passes the key/value pairs to the targeted Android application
-in a <code>com.google.android.c2dm.intent.RECEIVE</code> Intent as a set of
-extras.</li>
-  <li>The Android application extracts the raw data
-from the <code>com.google.android.c2dm.intent.RECEIVE</code><code> </code>Intent
-by key and processes the data.</li>
-</ol>
+<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>
 
-<p>See the documentation for each connection server for more detail on how it
-handles responses.</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>
