Method Detail

addSensorListener

public static void addSensorListener(SensorListener listener,
                                     SensorInfo info)

Register a listener to monitor the change of availability of a specific sensor

Parameters:

listener - the sensor listener

info - a SensorListener object returned from findSensors or SensorConnection.getSensorInfo

addSensorListener

public static void addSensorListener(SensorListener listener,
                                     String quantity)

Register a listener to monitor the change of availability of a sensor for a specific quantity

Parameters:

listener - the sensor listener

quantity - the required quantity

findSensors

public static SensorInfo[] findSensors(String url)

Find all available sensors that match a specific URL. Note that this only finds I2C sensors.

Parameters:

url - the specified URL

Returns:

an array of SensorInfo objects

findSensors

public static SensorInfo[] findSensors(String quantity,
                                       String contextType)

Find all available sensors that match a specific quantity and/or context. Note that this only finds I2C sensors.

Parameters:

quantity - the required quantity or null for any

contextType - the required context type or null for any

Returns:

an array of SensorInfo objects

removeSensorListener

public static void removeSensorListener(SensorListener listener)

Remove the specified sensor listener

Parameters:

listener - the sensor listener

findQuantity
