Class DeviceSensor

java.lang.Object

eu.h2020.helios_social.core.sensor.Sensor

eu.h2020.helios_social.core.sensor.ext.DeviceSensor

All Implemented Interfaces:

android.hardware.SensorEventListener

public class DeviceSensor
extends Sensor
implements android.hardware.SensorEventListener

DeviceSensor - This class provides methods to use Android devices build-in sensors that measure motion, orientation, and various environmental conditions. This class implements the Android SensorEventListener interface {@see android.hardware.SensorEventListener} and use the Android SensorManager class {@see android.hardware.SensorManager}. For available types {@see https://developer.android.com/guide/topics/sensors/sensors_overview#sensor-availability} This class extends the base Helios Sensor class.
