TYPE_ACCELEROMETER- #TYPE_AMBIENT_LIGHT
- #TYPE_COMPASS
TYPE_GYROSCOPETYPE_MAGNETOMETER- #TYPE_MOTION
public boolean isActive ()
Indicates whether sensor updates are currently happening.
Returns
- true if the Sensor is currently used
public void setListener (SensorListener listener)
Sets the listener allowing to receive notifications from the Sensor when sensor values have changed.
See Also
public void start (int period)
Starts data acquisition from the sensor.
Becarefull when you give the speed rate as a parameter. For some devices the speed rate could be to hight compared to the performance of the embedded sensor leading to fatal error.
Parameters
| period | is the rate chosen for data's recording |
|---|
public void stop ()
Stops data acquisition from the sensor.
