Field

int	SENSOR_ACCELEROMETER A constant describing an accelerometer.
int	DATA_X Index of the X value in the array returned by android.hardware.SensorListener#onSensorChanged
int	DATA_Y Index of the Y value in the array returned by android.hardware.SensorListener#onSensorChanged
int	DATA_Z Index of the Z value in the array returned by android.hardware.SensorListener#onSensorChanged
float	GRAVITY_EARTH Earth's gravity in SI units (m/s^2)
float	MAGNETIC_FIELD_EARTH_MAX Maximum magnetic field on Earth's surface
float	PRESSURE_STANDARD_ATMOSPHERE Standard atmosphere, or average sea-level pressure in hPa (millibar)
int	SENSOR_DELAY_FASTEST get sensor data as fast as possible
int	SENSOR_DELAY_GAME rate suitable for games
int	SENSOR_DELAY_UI rate suitable for the user interface
int	SENSOR_DELAY_NORMAL rate (default) suitable for screen orientation changes
int	SENSOR_STATUS_UNRELIABLE The values returned by this sensor cannot be trusted, calibration is needed or the environment doesn't allow readings
int	SENSOR_STATUS_ACCURACY_LOW This sensor is reporting data with low accuracy, calibration with the environment is needed
int	SENSOR_STATUS_ACCURACY_MEDIUM This sensor is reporting data with an average level of accuracy, calibration with the environment may improve the readings
int	SENSOR_STATUS_ACCURACY_HIGH This sensor is reporting data with maximum accuracy

Method

float	getAltitude(float p0, float p) Computes the Altitude in meters from the atmospheric pressure and the pressure at sea level.
Sensor	getDefaultSensor(int type) Use this method to get the default sensor for a given type.
float[]	getOrientation(float[] R, float[] values) Computes the device's orientation based on the rotation matrix.
void	getQuaternionFromVector(float[] Q, float[] rv) Helper function to convert a rotation vector to a normalized quaternion.
boolean	getRotationMatrix(float[] R, float[] I, float[] gravity, float[] geomagnetic) Computes the inclination matrix I as well as the rotation matrix R transforming a vector from the device coordinate system to the world's coordinate system which is defined as a direct orthonormal basis, where: X is defined as the vector product Y.Z (It is tangential to the ground at the device's current location and roughly points East). Y is tangential to the ground at the device's current location and points towards the magnetic North Pole. Z points towards the sky and is perpendicular to the ground.
void	getRotationMatrixFromVector(float[] R, float[] rotationVector) Helper function to convert a rotation vector to a rotation matrix.
List	getSensorList(int type) Use this method to get the list of available sensors of a certain type.
boolean	registerListener(SensorListener listener, int sensors, int rate) Registers a SensorListener for given sensors.
boolean	registerListener(SensorEventListener listener, Sensor sensor, int samplingPeriodUs) Registers a android.hardware.SensorEventListener SensorEventListener for the given sensor at the given sampling frequency.
boolean	registerListener(SensorEventListener listener, Sensor sensor, int samplingPeriodUs, int maxReportLatencyUs) Registers a android.hardware.SensorEventListener SensorEventListener for the given sensor at the given sampling frequency and the given maximum reporting latency.
boolean	registerListener(SensorEventListener listener, Sensor sensor, int samplingPeriodUs, Handler handler) Registers a android.hardware.SensorEventListener SensorEventListener for the given sensor.
boolean	remapCoordinateSystem(float[] inR, int X, int Y, float[] outR) Rotates the supplied rotation matrix so it is expressed in a different coordinate system.
void	unregisterListener(SensorListener listener) Unregisters a listener for all sensors.
void	unregisterListener(SensorEventListener listener) Unregisters a listener for all sensors.
void	unregisterListener(SensorListener listener, int sensors) Unregisters a listener for the sensors with which it is registered.
void	unregisterListener(SensorEventListener listener, Sensor sensor) Unregisters a listener for the sensors with which it is registered.
