+
+
+<p>This lesson explains how to create and issue a notification.</p>
+
+<p>The examples in this class are based on the
+{@link android.support.v4.app.NotificationCompat.Builder} class.
+{@link android.support.v4.app.NotificationCompat.Builder}
+is in the <a href="{@docRoot}">Support Library</a>. You should use
+{@link android.support.v4.app.NotificationCompat} and its subclasses,
+particularly {@link android.support.v4.app.NotificationCompat.Builder}, to
+provide the best notification support for a wide range of platforms. </p>
+
+<h2 id="builder">Create a Notification Builder</h2>
+
+<p>When creating a notification, specify the UI content and actions with a
+{@link android.support.v4.app.NotificationCompat.Builder} object. At bare minimum,
+a {@link android.support.v4.app.NotificationCompat.Builder Builder}
+object must include the following:</p>
+
+<ul>
+ <li>
+ A small icon, set by
+ {@link android.support.v4.app.NotificationCompat.Builder#setSmallIcon setSmallIcon()}
+ </li>
+ <li>
+ A title, set by
+ {@link android.support.v4.app.NotificationCompat.Builder#setContentTitle setContentTitle()}
+ </li>
+ <li>
+ Detail text, set by
+ {@link android.support.v4.app.NotificationCompat.Builder#setContentText setContentText()}
+ </li>
+</ul>
+<p> For example: </p>
+<pre>
+NotificationCompat.Builder mBuilder =
+ new NotificationCompat.Builder(this)
+ .setSmallIcon(R.drawable.notification_icon)
+ .setContentTitle(&quot;My notification&quot;)
+ .setContentText(&quot;Hello World!&quot;);
+</pre>
+
+<h2 id="action">Define the Notification's Action</h2>
+
+
+<p>Although actions are optional, you should add at least one action to your
+notification. An action takes users directly from the notification to an
+{@link android.app.Activity} in your application, where they can look at the
+event that caused the notification or do further work. Inside a notification, the action itself is
+defined by a {@link android.app.PendingIntent} containing an {@link
+android.content.Intent} that starts an {@link android.app.Activity} in your
+application.</p>
+
+<p>How you construct the {@link android.app.PendingIntent} depends on what type
+of {@link android.app.Activity} you're starting. When you start an {@link
+android.app.Activity} from a notification, you must preserve the user's expected
+navigation experience. In the snippet below, clicking the notification opens a
+new activity that effectively extends the behavior of the notification. In this
+case there is no need to create an artificial back stack (see
+<a href="navigation.html">Preserving Navigation when Starting an Activity</a> for
+more information):</p>
+
+<pre>Intent resultIntent = new Intent(this, ResultActivity.class);
+...
+// Because clicking the notification opens a new ("special") activity, there's
+// no need to create an artificial back stack.
+PendingIntent resultPendingIntent =
+ PendingIntent.getActivity(
+ this,
+ 0,
+ resultIntent,
+ PendingIntent.FLAG_UPDATE_CURRENT
+);
+</pre>
+
+<h2 id="click">Set the Notification's Click Behavior</h2>
+
+<p>
+To associate the {@link android.app.PendingIntent} created in the previous
+step with a gesture, call the appropriate method of {@link
+android.support.v4.app.NotificationCompat.Builder}. For example, to start an
+activity when the user clicks the notification text in the notification drawer,
+add the {@link android.app.PendingIntent} by calling {@link
+android.support.v4.app.NotificationCompat.Builder#setContentIntent
+setContentIntent()}. For example:</p>
+
+<pre>PendingIntent resultPendingIntent;
+...
+mBuilder.setContentIntent(resultPendingIntent);</pre>
+
+<h2 id="notify">Issue the Notification</h2>
+
+<p>To issue the notification:</p>
+<ul>
+<li>Get an instance of {@link android.app.NotificationManager}.</li>
+
+<li>Use the {@link android.app.NotificationManager#notify notify()} method to issue the
+notification. When you call {@link android.app.NotificationManager#notify notify()}, specify a notification ID.
+You can use this ID to update the notification later on. This is described in more detail in
+<a href="managing.html">Managing Notifications</a>.</li>
+
+<li>Call {@link
+android.support.v4.app.NotificationCompat.Builder#build() build()}, which
+returns a {@link android.app.Notification} object containing your
+specifications.</li>
+
+<p>For example:</p>
+
+<pre>
+// Sets an ID for the notification
+int mNotificationId = 001;
+// Gets an instance of the NotificationManager service
+NotificationManager mNotifyMgr =
+ (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
+// Builds the notification and issues it.
+mNotifyMgr.notify(mNotificationId, builder.build());
+</pre>

+<p>
+ Notifications can include an animated progress indicator that shows users the status
+ of an ongoing operation. If you can estimate how long the operation takes and how much of it
+ is complete at any time, use the "determinate" form of the indicator
+ (a progress bar). If you can't estimate the length of the operation, use the
+ "indeterminate" form of the indicator (an activity indicator).
+</p>
+<p>
+ Progress indicators are displayed with the platform's implementation of the
+ {@link android.widget.ProgressBar} class.
+</p>
+<p>
+ To use a progress indicator, call
+ {@link android.support.v4.app.NotificationCompat.Builder#setProgress setProgress()}. The
+ determinate and indeterminate forms are described in the following sections.
+</p>
+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="FixedProgress">Display a Fixed-duration Progress Indicator</h2>
+<p>
+ To display a determinate progress bar, add the bar to your notification by calling
+ {@link android.support.v4.app.NotificationCompat.Builder#setProgress
+ setProgress(max, progress, false)} and then issue the notification.
+ The third argument is a boolean that indicates whether the
+ progress bar is indeterminate (<strong>true</strong>) or determinate (<strong>false</strong>).
+ As your operation proceeds,
+ increment <code>progress</code>, and update the notification. At the end of the operation,
+ <code>progress</code> should equal <code>max</code>. A common way to call
+ {@link android.support.v4.app.NotificationCompat.Builder#setProgress setProgress()}
+ is to set <code>max</code> to 100 and then increment <code>progress</code> as a
+ "percent complete" value for the operation.
+</p>
+<p>
+ You can either leave the progress bar showing when the operation is done, or remove it. In
+ either case, remember to update the notification text to show that the operation is complete.
+ To remove the progress bar, call
+ {@link android.support.v4.app.NotificationCompat.Builder#setProgress
+ setProgress(0, 0, false)}. For example:
+</p>
+<pre>
+...
+mNotifyManager =
+ (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
+mBuilder = new NotificationCompat.Builder(this);
+mBuilder.setContentTitle("Picture Download")
+ .setContentText("Download in progress")
+ .setSmallIcon(R.drawable.ic_notification);
+// Start a lengthy operation in a background thread
+new Thread(
+ new Runnable() {
+ &#64;Override
+ public void run() {
+ int incr;
+ // Do the "lengthy" operation 20 times
+ for (incr = 0; incr &lt;= 100; incr+=5) {
+ // Sets the progress indicator to a max value, the
+ // current completion percentage, and "determinate"
+ // state
+ mBuilder.setProgress(100, incr, false);
+ // Displays the progress bar for the first time.
+ mNotifyManager.notify(0, mBuilder.build());
+ // Sleeps the thread, simulating an operation
+ // that takes time
+ try {
+ // Sleep for 5 seconds
+ Thread.sleep(5*1000);
+ } catch (InterruptedException e) {
+ Log.d(TAG, "sleep failure");
+ }
+ }
+ // When the loop is finished, updates the notification
+ mBuilder.setContentText("Download complete")
+ // Removes the progress bar
+ .setProgress(0,0,false);
+ mNotifyManager.notify(ID, mBuilder.build());
+ }
+ }
+// Starts the thread by calling the run() method in its Runnable
+).start();
+</pre>
+<p>
+ The resulting notifications are shown in figure 1. On the left side is a snapshot of the
+ notification during the operation; on the right side is a snapshot of it after the operation
+ has finished.
+</p>

+ id="figure1"
+ src="{@docRoot}images/ui/notifications/progress_bar_summary.png"
+ height="84"
+ alt="" />
+<p class="img-caption">
+<strong>Figure 1.</strong> The progress bar during and after the operation.</p>
+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="ActivityIndicator">Display a Continuing Activity Indicator</h2>
+<p>
+ To display a continuing (indeterminate) activity indicator, add it to your notification with
+ {@link android.support.v4.app.NotificationCompat.Builder#setProgress setProgress(0, 0, true)}
+ and issue the notification. The first two arguments are ignored, and the third argument
+ declares that the indicator is indeterminate. The result is an indicator
+ that has the same style as a progress bar, except that its animation is ongoing.
+</p>
+<p>
+ Issue the notification at the beginning of the operation. The animation will run until you
+ modify your notification. When the operation is done, call
+ {@link android.support.v4.app.NotificationCompat.Builder#setProgress
+ setProgress(0, 0, false)} and then update the notification to remove the activity indicator.
+ Always do this; otherwise, the animation will run even when the operation is complete. Also
+ remember to change the notification text to indicate that the operation is complete.
+</p>
+<p>
+ To see how continuing activity indicators work, refer to the preceding snippet. Locate the following lines:
+</p>
+<pre>
+// Sets the progress indicator to a max value, the current completion
+// percentage, and "determinate" state
+mBuilder.setProgress(100, incr, false);
+// Issues the notification
+mNotifyManager.notify(0, mBuilder.build());
+</pre>
+<p>
+ Replace the lines you've found with the following lines. Notice that the third parameter
+ in the {@link android.support.v4.app.NotificationCompat.Builder#setProgress setProgress()}
+ call is set to {@code true} to indicate that the progress bar is
+ indeterminate:
+</p>
+<pre>
+ // Sets an activity indicator for an operation of indeterminate length
+mBuilder.setProgress(0, 0, true);
+// Issues the notification
+mNotifyManager.notify(0, mBuilder.build());
+</pre>
+<p>
+ The resulting indicator is shown in figure 2:
+</p>
+<img
+ id="figure2"
+ src="{@docRoot}images/ui/notifications/activity_indicator.png"

+
+<p>Notifications in the notification drawer appear in two main visual styles,
+normal view and big view. The big view of a notification only appears when the
+notification is expanded. This happens when the notification is at the top of
+the drawer, or the user clicks the notification. </p>
+
+<p>Big views were introduced in
+Android 4.1, and they're not supported on older devices. This lesson describes
+how to incorporate big view notifications into your app while still providing
+full functionality via the normal view. See the <a
+href="{@docRoot}guide/topics/ui/notifiers/notifications.html#BigNotify">
+Notifications API guide</a> for more discussion of big views.</p>
+
+<p>Here is an example of a normal view: </p>
+
+<img src="{@docRoot}images/training/notifications-normalview.png" width="300" height="58" alt="normal view" />
+
+<p class="img-caption">
+ <strong>Figure 1.</strong> Normal view notification.
+</p>
+
+
+<p>Here is an example of a big view:</p>
+
+<img src="{@docRoot}images/training/notifications-bigview.png" width="300" height="143" alt="big view" />
+<p class="img-caption">
+ <strong>Figure 2.</strong> Big view notification.
+</p>
+
+
+<p> In the sample application shown in this lesson, both the normal view and the
+big view give users access to same functionality:</p>
+
+<ul>
+ <li>The ability to snooze or dismiss the notification.</li>
+ <li>A way to view the reminder text the user set as part of the timer.</li>
+</ul>
+
+<p>The normal view provides these features through a new activity that launches
+when the user clicks the notification. Keep this in mind as you design your notifications&mdash;first
+provide the functionality in the normal view, since
+this is how many users will interact with the notification.</p>
+
+<h2 id="activity">Set Up the Notification to Launch a New Activity</h2>
+
+<p>The sample application uses an {@link android.app.IntentService} subclass ({@code PingService})
+to construct and issue the notification.</p>
+
+
+<p>In this snippet, the
+{@link android.app.IntentService} method
+{@link android.app.IntentService#onHandleIntent onHandleIntent()} specifies the new activity
+that will be launched if the user
+clicks the notification itself. The method
+{@link android.support.v4.app.NotificationCompat.Builder#setContentIntent setContentIntent()}
+defines a pending intent that should be fired when the user
+clicks the notification, thereby launching the activity.</p>
+
+<pre>Intent resultIntent = new Intent(this, ResultActivity.class);
+resultIntent.putExtra(CommonConstants.EXTRA_MESSAGE, msg);
+resultIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
+ Intent.FLAG_ACTIVITY_CLEAR_TASK);
+
+// Because clicking the notification launches a new ("special") activity,
+// there's no need to create an artificial back stack.
+PendingIntent resultPendingIntent =
+ PendingIntent.getActivity(
+ this,
+ 0,
+ resultIntent,
+ PendingIntent.FLAG_UPDATE_CURRENT
+);
+
+// This sets the pending intent that should be fired when the user clicks the
+// notification. Clicking the notification launches a new activity.
+builder.setContentIntent(resultPendingIntent);
+</pre>
+
+<h2 id="big-view">Construct the Big View</h2>
+
+<p>This snippet shows how to set up the buttons that will appear in the big view:</p>
+
+<pre>
+// Sets up the Snooze and Dismiss action buttons that will appear in the
+// big view of the notification.
+Intent dismissIntent = new Intent(this, PingService.class);
+dismissIntent.setAction(CommonConstants.ACTION_DISMISS);
+PendingIntent piDismiss = PendingIntent.getService(this, 0, dismissIntent, 0);
+
+Intent snoozeIntent = new Intent(this, PingService.class);
+snoozeIntent.setAction(CommonConstants.ACTION_SNOOZE);
+PendingIntent piSnooze = PendingIntent.getService(this, 0, snoozeIntent, 0);
+</pre>
+
+<p>This snippet shows how to construct the
+{@link android.support.v4.app.NotificationCompat.Builder Builder} object.
+It sets the style for the big
+view to be "big text," and sets its content to be the reminder message. It uses
+{@link android.support.v4.app.NotificationCompat.Builder#addAction addAction()}
+to add the <strong>Snooze</strong> and <strong>Dismiss</strong> buttons (and
+their associated pending intents) that will appear in the notification's
+big view:</p>
+
+<pre>// Constructs the Builder object.
+NotificationCompat.Builder builder =
+ new NotificationCompat.Builder(this)
+ .setSmallIcon(R.drawable.ic_stat_notification)
+ .setContentTitle(getString(R.string.notification))
+ .setContentText(getString(R.string.ping))
+ .setDefaults(Notification.DEFAULT_ALL) // requires VIBRATE permission
+ /*
+ * Sets the big view "big text" style and supplies the
+ * text (the user's reminder message) that will be displayed
+ * in the detail area of the expanded notification.
+ * These calls are ignored by the support library for
+ * pre-4.1 devices.
+ */
+ .setStyle(new NotificationCompat.BigTextStyle()
+ .bigText(msg))
+ .addAction (R.drawable.ic_stat_dismiss,
+ getString(R.string.dismiss), piDismiss)
+ .addAction (R.drawable.ic_stat_snooze,
+ getString(R.string.snooze), piSnooze);

+ When you need to issue a notification multiple times for the same type of event, you
+ should avoid making a completely new notification. Instead, you should consider updating a
+ previous notification, either by changing some of its values or by adding to it, or both.
+</p>
+
+<p>
+ The following section describes how to update notifications and also how to remove them.
+</p>
+<h2 id="Updating">Modify a Notification</h2>
+<p>
+ To set up a notification so it can be updated, issue it with a notification ID by
+ calling {@link android.app.NotificationManager#notify(int, Notification)
+ NotificationManager.notify(ID, notification)}. To update this notification once you've issued
+ it, update or create a {@link android.support.v4.app.NotificationCompat.Builder} object,
+ build a {@link android.app.Notification} object from it, and issue the
+ {@link android.app.Notification} with the same ID you used previously.
+</p>
+<p>
+ The following snippet demonstrates a notification that is updated to reflect the
+ number of events that have occurred. It stacks the notification, showing a summary:
+</p>
+<pre>
+mNotificationManager =
+ (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
+// Sets an ID for the notification, so it can be updated
+int notifyID = 1;
+mNotifyBuilder = new NotificationCompat.Builder(this)
+ .setContentTitle("New Message")
+ .setContentText("You've received new messages.")
+ .setSmallIcon(R.drawable.ic_notify_status)
+numMessages = 0;
+// Start of a loop that processes data and then notifies the user
+...
+ mNotifyBuilder.setContentText(currentText)
+ .setNumber(++numMessages);
+ // Because the ID remains unchanged, the existing notification is
+ // updated.
+ mNotificationManager.notify(
+ notifyID,
+ mNotifyBuilder.build());
+...
+</pre>
+
+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="Removing">Remove Notifications</h2>
+<p>
+ Notifications remain visible until one of the following happens:
+</p>
+<ul>
+ <li>
+ The user dismisses the notification either individually or by using "Clear All" (if
+ the notification can be cleared).
+ </li>
+ <li>
+ The user touches the notification, and you called
+ {@link android.support.v4.app.NotificationCompat.Builder#setAutoCancel setAutoCancel()} when
+ you created the notification.
+ </li>
+ <li>
+ You call {@link android.app.NotificationManager#cancel(int) cancel()} for a specific
+ notification ID. This method also deletes ongoing notifications.
+ </li>
+ <li>
+ You call {@link android.app.NotificationManager#cancelAll() cancelAll()}, which removes
+ all of the notifications you previously issued.
+ </li>

+ Part of designing a notification is preserving the user's expected navigation experience.
+ For a detailed discussion of this topic, see the
+ <a href="{@docRoot}guide/topics/ui/notifiers/notifications.html#NotificationResponse">Notifications</a>
+ API guide.
+ There are two general situations:
+</p>
+<dl>
+ <dt>
+ Regular activity
+ </dt>
+ <dd>
+ You're starting an {@link android.app.Activity} that's part of the application's normal
+ workflow.
+ </dd>
+ <dt>
+ Special activity
+ </dt>
+ <dd>
+ The user only sees this {@link android.app.Activity} if it's started from a notification.
+ In a sense, the {@link android.app.Activity} extends the notification by providing
+ information that would be hard to display in the notification itself.
+ </dd>
+</dl>
+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="DirectEntry">Set Up a Regular Activity PendingIntent</h2>
+<p>
+ To set up a {@link android.app.PendingIntent} that starts a direct entry
+ {@link android.app.Activity}, follow these steps:
+</p>
+<ol>
+ <li>
+ Define your application's {@link android.app.Activity} hierarchy in the manifest. The final XML should look like this:
+ </p>
+<pre>
+&lt;activity
+ android:name=".MainActivity"
+ android:label="&#64;string/app_name" &gt;
+ &lt;intent-filter&gt;
+ &lt;action android:name="android.intent.action.MAIN" /&gt;
+ &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
+ &lt;/intent-filter&gt;
+&lt;/activity&gt;
+&lt;activity
+ android:name=".ResultActivity"
+ android:parentActivityName=".MainActivity"&gt;
+ &lt;meta-data
+ android:name="android.support.PARENT_ACTIVITY"
+ android:value=".MainActivity"/&gt;
+&lt;/activity&gt;
+</pre>
+ </li>
+ <li>
+ Create a back stack based on the {@link android.content.Intent} that starts the
+ {@link android.app.Activity}. For example:
+</p>
+<pre>
+...
+Intent resultIntent = new Intent(this, ResultActivity.class);
+TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
+// Adds the back stack
+stackBuilder.addParentStack(ResultActivity.class);
+// Adds the Intent to the top of the stack
+stackBuilder.addNextIntent(resultIntent);
+// Gets a PendingIntent containing the entire back stack
+PendingIntent resultPendingIntent =
+ stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
+...
+NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
+builder.setContentIntent(resultPendingIntent);
+NotificationManager mNotificationManager =
+ (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
+mNotificationManager.notify(id, builder.build());
+</pre>
+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="ExtendedNotification">Set Up a Special Activity PendingIntent</h2>
+
+<p>
+ A special {@link android.app.Activity} doesn't need a back stack, so you don't have to
+ define its {@link android.app.Activity} hierarchy in the manifest, and you don't have
+ to call
+ {@link android.support.v4.app.TaskStackBuilder#addParentStack addParentStack()} to build a
+ back stack. Instead, use the manifest to set up the {@link android.app.Activity} task options,
+ and create the {@link android.app.PendingIntent} by calling
+ {@link android.app.PendingIntent#getActivity getActivity()}:
+</p>
+<ol>
+ <li>
+ In your manifest, add the following attributes to the
+<code><a href="{@docRoot}guide/topics/manifest/activity-element.html">&lt;activity&gt;</a></code>
+ element for the {@link android.app.Activity}:
+ <dl>
+ <dt>
+<code><a href="{@docRoot}guide/topics/manifest/activity-element.html#nm">android:name</a>="<i>activityclass</i>"</code>
+ </dt>
+ <dd>
+ The activity's fully-qualified class name.
+ </dd>
+ <dt>
+<code><a href="{@docRoot}guide/topics/manifest/activity-element.html#aff">android:taskAffinity</a>=""</code>
+ </dt>
+ <dd>
+ Combined with the
+ {@link android.content.Intent#FLAG_ACTIVITY_NEW_TASK FLAG_ACTIVITY_NEW_TASK} flag
+ that you set in code, this ensures that this {@link android.app.Activity} doesn't
+ go into the application's default task. Any existing tasks that have the
+ application's default affinity are not affected.
+ </dd>
+ <dt>
+<code><a href="{@docRoot}guide/topics/manifest/activity-element.html#exclude">android:excludeFromRecents</a>="true"</code>
+ </dt>
+ <dd>
+ Excludes the new task from <i>Recents</i>, so that the user can't accidentally
+ navigate back to it.
+ </dd>
+ </dl>
+ <p>
+ This snippet shows the element:
+ </p>
+<pre>
+&lt;activity
+ android:name=".ResultActivity"
+...
+ android:launchMode="singleTask"
+ android:taskAffinity=""
+ android:excludeFromRecents="true"&gt;
+&lt;/activity&gt;
+...
+</pre>
+ </li>
+ <li>
+ Build and issue the notification:
+ <ol style="list-style-type: lower-alpha;">
+ <li>
+ Create an {@link android.content.Intent} that starts the
+ {@link android.app.Activity}.
+ </li>
+ <li>
+ Set the {@link android.app.Activity} to start in a new, empty task by calling
+ {@link android.content.Intent#setFlags setFlags()} with the flags
+ {@link android.content.Intent#FLAG_ACTIVITY_NEW_TASK FLAG_ACTIVITY_NEW_TASK}
+ and
+ {@link android.content.Intent#FLAG_ACTIVITY_CLEAR_TASK FLAG_ACTIVITY_CLEAR_TASK}.
+ </li>
+ <li>
+ Set any other options you need for the {@link android.content.Intent}.
+ </li>
+ <li>
+ Create a {@link android.app.PendingIntent} from the {@link android.content.Intent}
+ by calling {@link android.app.PendingIntent#getActivity getActivity()}.
+ You can then use this {@link android.app.PendingIntent} as the argument to
+ {@link android.support.v4.app.NotificationCompat.Builder#setContentIntent
+ setContentIntent()}.
+ </li>
+ </ol>
+ <p>
+ The following code snippet demonstrates the process:
+ </p>
+<pre>
+// Instantiate a Builder object.
+NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
+// Creates an Intent for the Activity
+Intent notifyIntent =
+ new Intent(new ComponentName(this, ResultActivity.class));
+// Sets the Activity to start in a new, empty task
+notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
+ Intent.FLAG_ACTIVITY_CLEAR_TASK);
+// Creates the PendingIntent
+PendingIntent notifyIntent =
+ PendingIntent.getActivity(
+ this,
+ 0,
+ notifyIntent,
+ PendingIntent.FLAG_UPDATE_CURRENT
+);
+
+// Puts the PendingIntent into the notification builder
+builder.setContentIntent(notifyIntent);
+// Notifications are issued by sending them to the
+// NotificationManager system service.
+NotificationManager mNotificationManager =
+ (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
+// Builds an anonymous Notification object from the builder, and
+// passes it to the NotificationManager
+mNotificationManager.notify(id, builder.build());
+</pre>
+ </li>
+</ol>
