http://stackoverflow.com/questions/8734190/android-compass-example found several samples some use only Sensor.TYPE_ORIENTATION some use a combination of Sensor.TYPE_ACCELEROMETER Sensor.TYPE_MAGNETIC_FIELD . Which is the correct common way to get the bearing for let's say Android 1.6 4.0 android compass geolocation share.. you should use SensorManager.getOrientation instead. So you should read from Sensor.TYPE_ACCELEROMETER as well as from Sensor.TYPE_MAGNETIC_FIELD and then call SensorManager.getRotationMatrix and finally SensorManager.getOrientation which will return you the orientation..
