Hi, GPS bearing will only become accurate when the device is moving not when it is stationary.
Also it looks like you have not registered your orientation sensor listener with the Sensor Manager, see onPause() & on Resume() in http://developer.android.com/guide/topics/sensors/sensors_position.html Regards On Tuesday, September 18, 2012 4:30:08 PM UTC+10, Hung wrote: > > Hi guys, I am trying to get some good consistent data on one's > bearings(direction you are facing) either using the LocationListener class > or the SensorEventListener class.
