/**
 * A Service is an application component representing either an application's desire
 * to perform a longer-running operation while not interacting with the user
 * or to supply functionality for other applications to use.  Each service
 * class must have a corresponding
 * {@link android.R.styleable#AndroidManifestService }
 * declaration in its package's AndroidManifest.xml.  Services
 * can be started with
 * {@link android.content.Context#startService Context.startService()} and
 * {@link android.content.Context#bindService Context.bindService()}.
 * 
 * 
Note that services, like other application objects, run in the main
 * thread of their hosting process.  This means that, if your service is going
 * to do any CPU intensive (such as MP3 playback) or blocking (such as
 * networking) operations, it should spawn its own thread in which to do that
 * work.  More information on this can be found in
 * Processes and
 * Threads.  The {@link IntentService} class is available
 * as a standard implementation of Service that has its own thread where it
 * schedules its work to be done.

Developer Guides

For a detailed discussion about how to create services, read the
 * Services developer guide.
 * 
 *
 * 
 * 
What is a Service?
 * 
 * 
Most confusion about the Service class actually revolves around what
 * it is not:
 * 
 * 

 * 
 A Service is not a separate process.  The Service object itself
 * does not imply it is running in its own process; unless otherwise specified,
 * it runs in the same process as the application it is part of.
 * 
 A Service is not a thread.  It is not a means itself to do work off
 * of the main thread (to avoid Application Not Responding errors).
 * 
 * 
 * 
Thus a Service itself is actually very simple, providing two main features:
 * 
 * 

 * 
A facility for the application to tell the system about
 * something it wants to be doing in the background (even when the user is not
 * directly interacting with the application).  This corresponds to calls to
 * {@link android.content.Context#startService Context.startService()}, which
 * ask the system to schedule work for the service, to be run until the service
 * or someone else explicitly stop it.
 * 
A facility for an application to expose some of its functionality to
 * other applications.  This corresponds to calls to
 * {@link android.content.Context#bindService Context.bindService()}, which
 * allows a long-standing connection to be made to the service in order to
 * interact with it.
 * 
 * 
 * 
When a Service component is actually created, for either of these reasons,
 * all that the system actually does is instantiate the component
 * and call its {@link #onCreate} and any other appropriate callbacks on the
 * main thread.  It is up to the Service to implement these with the appropriate
 * behavior, such as creating a secondary thread in which it does its work.
 * 
 * 
Note that because Service itself is so simple, you can make your
 * interaction with it as simple or complicated as you want: from treating it
 * as a local Java object that you make direct method calls on (as illustrated
 * by Local Service Sample), to providing
 * a full remoteable interface using AIDL.
 * 
 * 
 * 
Service Lifecycle
 * 
 * 
There are two reasons that a service can be run by the system.  If someone
 * calls {@link android.content.Context#startService Context.startService()} then the system will
 * retrieve the service (creating it and calling its {@link #onCreate} method
 * if needed) and then call its {@link #onStartCommand} method with the
 * arguments supplied by the client.  The service will at this point continue
 * running until {@link android.content.Context#stopService Context.stopService()} or
 * {@link #stopSelf()} is called.  Note that multiple calls to
 * Context.startService() do not nest (though they do result in multiple corresponding
 * calls to onStartCommand()), so no matter how many times it is started a service
 * will be stopped once Context.stopService() or stopSelf() is called; however,
 * services can use their {@link #stopSelf(int)} method to ensure the service is
 * not stopped until started intents have been processed.
 * 
 * 
For started services, there are two additional major modes of operation
 * they can decide to run in, depending on the value they return from
 * onStartCommand(): {@link #START_STICKY} is used for services that are
 * explicitly started and stopped as needed, while {@link #START_NOT_STICKY}
 * or {@link #START_REDELIVER_INTENT} are used for services that should only
 * remain running while processing any commands sent to them.  See the linked
 * documentation for more detail on the semantics.
 * 
 * 
Clients can also use {@link android.content.Context#bindService Context.bindService()} to
 * obtain a persistent connection to a service.  This likewise creates the
 * service if it is not already running (calling {@link #onCreate} while
 * doing so), but does not call onStartCommand().  The client will receive the
 * {@link android.os.IBinder} object that the service returns from its
 * {@link #onBind} method, allowing the client to then make calls back
 * to the service.  The service will remain running as long as the connection
 * is established (whether or not the client retains a reference on the
 * service's IBinder).  Usually the IBinder returned is for a complex
 * interface that has been written
 * in aidl.
 * 
 * 
A service can be both started and have connections bound to it.  In such
 * a case, the system will keep the service running as long as either it is
 * started or there are one or more connections to it with the
 * {@link android.content.Context#BIND_AUTO_CREATE Context.BIND_AUTO_CREATE}
 * flag.  Once neither
 * of these situations hold, the service's {@link #onDestroy} method is called
 * and the service is effectively terminated.  All cleanup (stopping threads,
 * unregistering receivers) should be complete upon returning from onDestroy().
 * 
 * 
 * 
Permissions
 * 
 * 
Global access to a service can be enforced when it is declared in its
 * manifest's {@link android.R.styleable#AndroidManifestService }
 * tag.  By doing so, other applications will need to declare a corresponding
 * {@link android.R.styleable#AndroidManifestUsesPermission }
 * element in their own manifest to be able to start, stop, or bind to
 * the service.
 * 
 * 
In addition, a service can protect individual IPC calls into it with
 * permissions, by calling the
 * {@link #checkCallingPermission}
 * method before executing the implementation of that call.
 * 
 * 
See the Security and Permissions
 * document for more information on permissions and security in general.
 * 
 * 
 * 
Process Lifecycle
 * 
 * 
The Android system will attempt to keep the process hosting a service
 * around as long as the service has been started or has clients bound to it.
 * When running low on memory and needing to kill existing processes, the
 * priority of a process hosting the service will be the higher of the
 * following possibilities:
 * 
 * 

 * 
If the service is currently executing code in its
 * {@link #onCreate onCreate()}, {@link #onStartCommand onStartCommand()},
 * or {@link #onDestroy onDestroy()} methods, then the hosting process will
 * be a foreground process to ensure this code can execute without
 * being killed.
 * 
If the service has been started, then its hosting process is considered
 * to be less important than any processes that are currently visible to the
 * user on-screen, but more important than any process not visible.  Because
 * only a few processes are generally visible to the user, this means that
 * the service should not be killed except in extreme low memory conditions.
 * 
If there are clients bound to the service, then the service's hosting
 * process is never less important than the most important client.  That is,
 * if one of its clients is visible to the user, then the service itself is
 * considered to be visible.
 * 
A started service can use the {@link #startForeground(int, Notification)}
 * API to put the service in a foreground state, where the system considers
 * it to be something the user is actively aware of and thus not a candidate
 * for killing when low on memory.  (It is still theoretically possible for
 * the service to be killed under extreme memory pressure from the current
 * foreground application, but in practice this should not be a concern.)
 * 
 * 
 * 
Note this means that most of the time your service is running, it may
 * be killed by the system if it is under heavy memory pressure.  If this
 * happens, the system will later try to restart the service.  An important
 * consequence of this is that if you implement {@link #onStartCommand onStartCommand()}
 * to schedule work to be done asynchronously or in another thread, then you
 * may want to use {@link #START_FLAG_REDELIVERY} to have the system
 * re-deliver an Intent for you so that it does not get lost if your service
 * is killed while processing it.
 * 
 * 
Other application components running in the same process as the service
 * (such as an {@link android.app.Activity}) can, of course, increase the
 * importance of the overall
 * process beyond just the importance of the service itself.
 * 
 * 
 * 
Local Service Sample
 * 
 * 
One of the most common uses of a Service is as a secondary component
 * running alongside other parts of an application, in the same process as
 * the rest of the components.  All components of an .apk run in the same
 * process unless explicitly stated otherwise, so this is a typical situation.
 * 
 * 
When used in this way, by assuming the
 * components are in the same process, you can greatly simplify the interaction
 * between them: clients of the service can simply cast the IBinder they
 * receive from it to a concrete class published by the service.
 * 
 * 
An example of this use of a Service is shown here.  First is the Service
 * itself, publishing a custom class when bound:
 * 
 * {@sample development/samples/ApiDemos/src/com/example/android/apis/app/LocalService.java
 *      service}
 * 
 * 
With that done, one can now write client code that directly accesses the
 * running service, such as:
 * 
 * {@sample development/samples/ApiDemos/src/com/example/android/apis/app/LocalServiceActivities.java
 *      bind}
 * 
 * 
 * 
Remote Messenger Service Sample
 * 
 * 
If you need to be able to write a Service that can perform complicated
 * communication with clients in remote processes (beyond simply the use of
 * {@link Context#startService(Intent) Context.startService} to send
 * commands to it), then you can use the {@link android.os.Messenger} class
 * instead of writing full AIDL files.
 * 
 * 
An example of a Service that uses Messenger as its client interface
 * is shown here.  First is the Service itself, publishing a Messenger to
 * an internal Handler when bound:
 * 
 * {@sample development/samples/ApiDemos/src/com/example/android/apis/app/MessengerService.java
 *      service}
 * 
 * 
If we want to make this service run in a remote process (instead of the
 * standard one for its .apk), we can use android:process in its
 * manifest tag to specify one:
 * 
 * {@sample development/samples/ApiDemos/AndroidManifest.xml remote_service_declaration}
 * 
 * 
Note that the name "remote" chosen here is arbitrary, and you can use
 * other names if you want additional processes.  The ':' prefix appends the
 * name to your package's standard process name.
 * 
 * 
With that done, clients can now bind to the service and send messages
 * to it.  Note that this allows clients to register with it to receive
 * messages back as well:
 * 
 * {@sample development/samples/ApiDemos/src/com/example/android/apis/app/MessengerServiceActivities.java
 *      bind}
