Class Overview

Top-level service of the current global voice interactor, which is providing support for hotwording, the back-end of a VoiceInteractor, etc. The current VoiceInteractionService that has been selected by the user is kept always running by the system, to allow it to do things like listen for hotwords in the background to instigate voice interactions.

Because this service is always running, it should be kept as lightweight as possible. Heavy-weight operations (including showing UI) should be implemented in the associated VoiceInteractionSessionService when an actual voice interaction is taking place, and that service should run in a separate process from this one.

Inherited Methods

From class android.app.Service

void	dump(FileDescriptor fd, PrintWriter writer, String[] args) Print the Service's state into the given stream.
final Application	getApplication() Return the application that owns this service.
abstract IBinder	onBind(Intent intent) Return the communication channel to the service.
void	onConfigurationChanged(Configuration newConfig) Called by the system when the device configuration changes while your component is running.
void	onCreate() Called by the system when the service is first created.
void	onDestroy() Called by the system to notify a Service that it is no longer used and is being removed.
void	onLowMemory() This is called when the overall system is running low on memory, and actively running processes should trim their memory usage.
void	onRebind(Intent intent) Called when new clients have connected to the service, after it had previously been notified that all had disconnected in its `onUnbind(Intent)`.
void	onStart(Intent intent, int startId) This method was deprecated in API level 5. Implement `onStartCommand(Intent, int, int)` instead.
int	onStartCommand(Intent intent, int flags, int startId) Called by the system every time a client explicitly starts the service by calling `startService(Intent)`, providing the arguments it supplied and a unique integer token representing the start request.
void	onTaskRemoved(Intent rootIntent) This is called if the service is currently running and the user has removed a task that comes from the service's application.
void	onTrimMemory(int level) Called when the operating system has determined that it is a good time for a process to trim unneeded memory from its process.
boolean	onUnbind(Intent intent) Called when all clients have disconnected from a particular interface published by the service.
final void	startForeground(int id, Notification notification) Make this service run in the foreground, supplying the ongoing notification to be shown to the user while in this state.
final void	stopForeground(boolean removeNotification) Remove this service from foreground state, allowing it to be killed if more memory is needed.
final void	stopSelf() Stop the service, if it was previously started.
final void	stopSelf(int startId) Old version of `stopSelfResult(int)` that doesn't return a result.
final boolean	stopSelfResult(int startId) Stop the service if the most recent time it was started was `startId`.

From class android.content.Context

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Constants

public static final String SERVICE_INTERFACE

The Intent that must be declared as handled by the service. To be supported, the service must also require the BIND_VOICE_INTERACTION permission so that other applications can not abuse it.

Constant Value: "android.service.voice.VoiceInteractionService"

public static final String SERVICE_META_DATA

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

Constant Value: "android.voice_interaction"

Public Constructors

public VoiceInteractionService ()

Public Methods

public 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	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

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

public void onCreate ()

Called by the system when the service is first created. Do not call this method directly.
