Constructor Detail

SensorService

public SensorService()

Method Detail

onCreate

public void onCreate()

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

Overrides:

onCreate in class android.app.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.

Overrides:

onDestroy in class android.app.Service

onBind

public android.os.IBinder onBind(android.content.Intent intent)

When binding to the service, we return an interface to out messenger for sending messages to the service.

Specified by:

onBind in class android.app.Service

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 IBinder object used by Messenger.

onUnbind

public boolean onUnbind(android.content.Intent intent)

Called when all clients have disconnected from a particular interface published by the service. The default implementation does nothing and returns false.

Overrides:

onUnbind in class android.app.Service

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 true if you would like to have the service's Service.onRebind(android.content.Intent) method later called when new clients bind to it.

onStartCommand

public int onStartCommand(android.content.Intent intent,
                          int flags,
                          int startId)

Called by the system every time a client explicitly starts the service by calling Context.startService(android.content.Intent), providing the arguments it supplied and a unique integer token representing the start request. Do not call this method directly.

For backwards compatibility, the default implementation calls Service.onStart(android.content.Intent, int) and returns either Service.START_STICKY or Service.START_STICKY_COMPATIBILITY.

Note that the system calls this on your service's main thread. A service's main thread is the same thread where UI operations take place for Activities running in the same process. You should always avoid stalling the main thread's event loop. When doing long-running operations, network calls, or heavy disk I/O, you should kick off a new thread, or use AsyncTask.

Overrides:

onStartCommand in class android.app.Service

Parameters:

intent - The Intent supplied to Context.startService(android.content.Intent), as given. This may be null if the service is being restarted after its process has gone away, and it had previously returned anything except Service.START_STICKY_COMPATIBILITY.

flags - Additional data about this start request.

startId - A unique integer representing this specific request to start. Use with Service.stopSelfResult(int).

Returns:

The return value indicates what semantics the system should use for the service's current started state. It may be one of the constants associated with the Service.START_CONTINUATION_MASK bits.

See Also:

Service.stopSelfResult(int)

onTaskRemoved

public void onTaskRemoved(android.content.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. If you have set ServiceInfo.FLAG_STOP_WITH_TASK then you will not receive this callback; instead, the service will simply be stopped.

Overrides:

onTaskRemoved in class android.app.Service

Parameters:

rootIntent - The original root Intent that was used to launch the task that is being removed.

onSensorChanged

public void onSensorChanged(android.hardware.SensorEvent event)

Called when there is a new sensor event. Note that "on changed" is somewhat of a misnomer, as this will also be called if we have a new reading from a sensor with the exact same sensor values (but a newer timestamp).

See SensorManager for details on possible sensor types.

See also SensorEvent.

NOTE: The application doesn't own the event object passed as a parameter and therefore cannot hold on to it. The object may be part of an internal pool and may be reused by the framework.

Specified by:

onSensorChanged in interface android.hardware.SensorEventListener

Parameters:

event - the SensorEvent.

onAccuracyChanged

public void onAccuracyChanged(android.hardware.Sensor sensor,
                              int accuracy)

Called when the accuracy of the registered sensor has changed. Unlike onSensorChanged(), this is only called when this accuracy value changes.

See the SENSOR_STATUS_* constants in SensorManager for details.

Specified by:

onAccuracyChanged in interface android.hardware.SensorEventListener

Parameters:

sensor - The target Sensor object of interest.

accuracy - The new accuracy of this sensor, one of SensorManager.SENSOR_STATUS_*
