Method Summary
`Sensor`	`getDefaultSensor(int type)` Use this method to get the default sensor for a given type.
`static float`	`getInclination(float[] I)` Computes the geomagnetic inclination angle in radians from the inclination matrix I returned by `getRotationMatrix(float[], float[], float[], float[])`.
`static float[]`	`getOrientation(float[] R, float[] values)` Computes the device's orientation based on the rotation matrix.
`(package private) static int`	`getRotation()`
`static 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.
`List<Sensor>`	`getSensorList(int type)` Use this method to get the list of available sensors of a certain type.
`int`	`getSensors()` Deprecated. This method is deprecated, use `getSensorList(int)` instead
`void`	`onRotationChanged(int rotation)`
`boolean`	`registerListener(SensorEventListener listener, Sensor sensor, int rate)` Registers a `SensorEventListener` for the given sensor.
`boolean`	`registerListener(SensorEventListener listener, Sensor sensor, int rate, Handler handler)` Registers a `SensorEventListener` for the given sensor.
`boolean`	`registerListener(SensorListener listener, int sensors)` Deprecated. This method is deprecated, use `registerListener(SensorEventListener, Sensor, int)` instead.
`boolean`	`registerListener(SensorListener listener, int sensors, int rate)` Deprecated. This method is deprecated, use `registerListener(SensorEventListener, Sensor, int)` instead.
`static boolean`	`remapCoordinateSystem(float[] inR, int X, int Y, float[] outR)` Rotates the supplied rotation matrix so it is expressed in a different coordinate system.
`(package private) static int`	`sensors_data_close()`
`(package private) static int`	`sensors_data_init()`
`(package private) static int`	`sensors_data_open(FileDescriptor fd)`
`(package private) static int`	`sensors_data_poll(float[] values, int[] status, long[] timestamp)`
`(package private) static int`	`sensors_data_uninit()`
`void`	`unregisterListener(SensorEventListener listener)` Unregisters a listener for all sensors.
`void`	`unregisterListener(SensorEventListener listener, Sensor sensor)` Unregisters a listener for the sensors with which it is registered.
`void`	`unregisterListener(SensorListener listener)` Deprecated. This method is deprecated, use `unregisterListener(SensorEventListener)` instead.
`void`	`unregisterListener(SensorListener listener, int sensors)` Deprecated. This method is deprecated, use `unregisterListener(SensorEventListener, Sensor)` instead.
