Note that since Android 2.2 (API Level 8), the orientation sensor has been deprecated. The reason for deprecation was accuracy and precision issues, as this sensor is only reliable when the roll component is 0. Also, this sensor involves heavy processing from the accelerometer and magnetometer sensors. Instead of using raw values from the orientation sensor, it is recommended that you use the getRotationMatrix() method in conjunction with the getOrientation() method of SensorManager to compute the same orientation values that are given by the orientation sensor. We will see more details on this in the next section when we develop our compass using both the orientation sensor and alternative APIs.
