Summary

Nested classes
`class`	`RecognitionService.Callback` This class receives callbacks from the speech recognition service and forwards them to the user.

Constants
`String`	`SERVICE_INTERFACE` The `Intent` that must be declared as handled by the service.
`String`	`SERVICE_META_DATA` Name under which a RecognitionService component publishes information about itself.

Inherited constants

From class android.app.Service

`int`	`START_CONTINUATION_MASK` Bits returned by `onStartCommand(Intent, int, int)` describing how to continue the service if it is killed.
`int`	`START_FLAG_REDELIVERY` This flag is set in `onStartCommand(Intent, int, int)` if the Intent is a re-delivery of a previously delivered intent, because the service had previously returned `START_REDELIVER_INTENT` but had been killed before calling `stopSelf(int)` for that Intent.
`int`	`START_FLAG_RETRY` This flag is set in `onStartCommand(Intent, int, int)` if the Intent is a retry because the original attempt never got to or returned from `onStartCommand(android.content.Intent, int, int)`.
`int`	`START_NOT_STICKY` Constant to return from `onStartCommand(Intent, int, int)`: if this service's process is killed while it is started (after returning from `onStartCommand(Intent, int, int)`), and there are no new start intents to deliver to it, then take the service out of the started state and don't recreate until a future explicit call to `Context#startService`.
`int`	`START_REDELIVER_INTENT` Constant to return from `onStartCommand(Intent, int, int)`: if this service's process is killed while it is started (after returning from `onStartCommand(Intent, int, int)`), then it will be scheduled for a restart and the last delivered Intent re-delivered to it again via `onStartCommand(Intent, int, int)`.
`int`	`START_STICKY` Constant to return from `onStartCommand(Intent, int, int)`: if this service's process is killed while it is started (after returning from `onStartCommand(Intent, int, int)`), then leave it in the started state but don't retain this delivered intent.
`int`	`START_STICKY_COMPATIBILITY` Constant to return from `onStartCommand(Intent, int, int)`: compatibility version of `START_STICKY` that does not guarantee that `onStartCommand(Intent, int, int)` will be called again after being killed.
`int`	`STOP_FOREGROUND_DETACH` Flag for `stopForeground(int)`: if set, the notification previously provided to `startForeground(int, Notification)` will be detached from the service.
`int`	`STOP_FOREGROUND_REMOVE` Flag for `stopForeground(int)`: if set, the notification previously provided to `startForeground(int, Notification)` will be removed.

          android.content.ComponentCallbacks

`abstract void`	`onConfigurationChanged(Configuration newConfig)` Called by the system when the device configuration changes while your component is running.
`abstract void`	`onLowMemory()` This is called when the overall system is running low on memory, and actively running processes should trim their memory usage.

Constants

SERVICE_INTERFACE

public static final String SERVICE_INTERFACE

The Intent that must be declared as handled by the service.

Constant Value: "android.speech.RecognitionService"

SERVICE_META_DATA

public static final String SERVICE_META_DATA

Name under which a RecognitionService component publishes information about itself. This meta-data should reference an XML resource containing a <recognition-service> tag.

Constant Value: "android.speech"

Public constructors

RecognitionService

public RecognitionService ()

Public methods

onBind

public final IBinder onBind (Intent intent)

Return the communication channel to the service. May return null if clients can not bind to the service. The returned IBinder is usually for a complex interface that has been described using aidl.

Note that unlike other application components, calls on to the IBinder interface returned here may not happen on the main thread of the process. More information about the main thread can be found in Processes and Threads.

Parameters
`intent`	`Intent`: The Intent that was used to bind to this service, as given to `Context.bindService`. Note that any extras that were included with the Intent at that point will not be seen here.

Returns
`IBinder`	Return an IBinder through which clients can call on to the service.

onDestroy

public void onDestroy ()

Called by the system to notify a Service that it is no longer used and is being removed. The service should clean up any resources it holds (threads, registered receivers, etc) at this point. Upon return, there will be no more calls in to this Service object and it is effectively dead. Do not call this method directly.

Protected methods

onCancel

protected abstract void onCancel (RecognitionService.Callback listener)

Notifies the service that it should cancel the speech recognition.

Parameters
`listener`	`RecognitionService.Callback`

onStartListening

protected abstract void onStartListening (Intent recognizerIntent, 
                RecognitionService.Callback listener)

Notifies the service that it should start listening for speech.

Parameters
`recognizerIntent`	`Intent`: contains parameters for the recognition to be performed. The intent may also contain optional extras, see `RecognizerIntent`. If these values are not set explicitly, default values should be used by the recognizer.
`listener`	`RecognitionService.Callback`: that will receive the service's callbacks

onStopListening

protected abstract void onStopListening (RecognitionService.Callback listener)

Notifies the service that it should stop listening for speech. Speech captured so far should be recognized as if the user had stopped speaking at this point. This method is only called if the application calls it explicitly.

Parameters
`listener`	`RecognitionService.Callback`
