I *think* this comment refers to using e.g. Sensor.TYPE_ORIENTATION directly. Instead, if I'm reading the documentation correctly, you are supposed to take the values from a TYPE_ACCELEROMETER and TYPE_MAGNETIC_FIELD and feed them to getRotationMatrix(). > > Trouble is, none of those API calls mentioned actually reads any sensor > values > <http://developer.android.com/reference/android/hardware/SensorManager.html>, > they only perform computations. > >
