  throttling facility can be used to control how much a Loader is refreshed
  in this case.</dd>
</dl>
  
<h3 id="Service">Service</h3>
<dl>
  <dt><a href="LocalService.html">Local Service</a></dt>
  <dd>Demonstrate the implementation of a service that runs in the same
  process as its client(s).  Shows how those clients can either start/stop it
  with Context.startService and Context.stopService, or bind and call it with
  Context.bindService and Context.unindService.
  This also shows how you can simplify working
  with a service when you know it will only run in your own process.  The client
  code for interacting with the service is in
  <a href="LocalServiceActivities.html">Local Service Activities</a>.</dd>
  
  <dt><a href="MessengerService.html">Messenger Service</a></dt>
  <dd>Demonstrates binding to a Service whose interface is implemented with
  the Messenger class.  This is often an easier way to do remote communication
  with a Service than using a raw AIDL interface.  The client
  code for interacting with the service is in
  <a href="MessengerServiceActivities.html">Messenger Service Activities</a>.</dd>
  
  <dt><a href="RemoteService.html">Remote Service Controller and
        Remove Service Binding</a></dt>
  <dd>Demonstrates starting a service in a separate process, by assigning
  <code>android:process=&quot;:remote&quot;</code> to the service in the
  AndroidManifest.xml file.  Shows how those clients can either start/stop it
  with Context.startService and Context.stopService, or bind and call it with
  Context.bindService and Context.unindService.
  Binding is similar to the local service sample,
  but illustrates the additional work (defining aidl
  interfaces) needed to interact with a service in another process.  Also
  shows how a service can publish multiple interfaces and implement
  callbacks to its clients.</dd>

  <dt><a href="ServiceStartArguments.html">Service Start Arguments</a></dt>
  <dd>Demonstrates how you can use a Service as a job queue, where you 
  submit jobs to it with Context.startService instead of binding to the service.  Such a service
  automatically stops itself once all jobs have been processed.  This can be
  a very convenient way to interact with a service when you do not need
  a result back from it.</dd>
  
  <dt><a href="ForegroundService.html">Foreground Service</a></dt>
  <dd>Shows how you
  can write a Service that runs in the foreground and works on both pre-2.0
  and post-2.0 versions of the platform.  This example will selectively use
  the new foreground APIs that were introduced in Android 2.0 if they are
  available.</dd>

</dl>

<h3 id="Alarm">Alarm</h3>
<dl>
  <dt><a href="AlarmController.html">Alarm Controller</a></dt>
  <dd>Demonstrates two ways you can schedule alarms: a one-shot alarm that
  will happen once at a given time, and a repeating alarm that will happen
  first at a given time and then continually trigger at regular intervals
  after that.
  <dl>
  <dt>Code:
  <dd> <a href="AlarmController.html">AlarmController.java</a>
  <dd> <a href="OneShotAlarm.html">OneShotAlarm.java</a>
  <dd> <a href="RepeatingAlarm.html">RepeatingAlarm.java</a>
  <dt>Layout:
  <dd> <a href="../../../../../../res/layout/alarm_controller.html">
  alarm_controller.xml</a>
  </dl>
  </dd>

  <dt><a href="AlarmService.html">Alarm Service</a></dt>
  <dd>Demonstrates how you can schedule an alarm that causes a service to
    be started.  This is useful when you want to schedule alarms that initiate
    long-running operations, such as retrieving recent e-mails.
  <dl>
  <dt>Code:
  <dd> <a href="AlarmService.html">AlarmService.java</a>
  <dd> <a href="AlarmService_Service.html">AlarmService_Service.java</a>
  <dt>Layout:
  <dd> <a href="../../../../../../res/layout/alarm_service.html">
  alarm_service.xml</a>
  </dl>
  </dd>
</dl>

<h3 id="Notification">Notification</h3>
<dl>
  <dt><a href="NotifyWithText.html">NotifyWithText</a></dt>
  <dd>Demonstrates popup notifications of varying length.</dd>

  <dt><a href="IncomingMessage.html">IncomingMessage</a></dt>
  <dd> Demonstrates sending persistent and transient notifications, with a View object in the notification. It also demonstrated inflating a View object from an XML layout resource. </dd>

  <dt><a href="StatusBarNotifications.html">Status Bar Notifications</a></dt>
  <dd> Demonstrates a variety of different notifications that can be posted in
  the status bar, and a standard way for handling them.</dd>
</dl>

<h3 id="Search">Search</h3>
<dl>
  <dt><a href="SearchInvoke.html">SearchInvoke</a></dt>
  <dd>Demonstrates various ways in which activities can launch the Search UI.</dd>
  
  <dt><a href="SearchQueryResults.html">SearchQueryResults</a></dt>
  <dd>Demonstrates an activity that receives Search intents and handles them.</dd>
  
  <dt><a href="SearchSuggestionSampleProvider.html">SearchSuggestionSampleProvider</a></dt>
  <dd>Demonstrates how to configure and use the built-in "recent queries" suggestion provider.</dd>  
</dl>


<h3 id="Misc">Misc</h3>
<dl>
  <dt><a href="AlertDialogSamples.html">Alert Dialog Samples</a></dt>
  <dd>Demonstrates various styles of alert dialogs.</dd>
  
  <dt><a href="DeviceAdminSample.html">Device Admin Sample</a></dt>
  <dd>Demonstration of the implementation of a simple device administrator
  and its use of the DevicePolicyManager.</dd>
</dl>
