TYPE_ORIENTATION은 더이상 사용되지 않습니다.

TYPE_ORIENTATION을 이용해서 안드로이드 기기의 방향을 쉽게 얻을 수 있습니다.

 

 

sm = (SensorManager)this.getSystemService(Context.SENSOR_SERVICE);         gyroSensor = sm.getDefaultSensor(Sensor.TYPE_ORIENTATION);         gyroListener = new SensorEventListener() {                                               @Override                        public void onSensorChanged(SensorEvent event) {                               // TODO Auto-generated method stub                               float[] values = event.values;                               //float x= values[0];                               //float y = values[1];                               //float z = values[2];                        }                                               @Override                        public void onAccuracyChanged(Sensor sensor, int accuracy) {                               // TODO Auto-generated method stub                                                      }                };

 

 

그런데 Warning을 살펴보시면 아래와 같은 메세지를 확인 할 수 있습니다.

 

The field Sensor.TYPE_ORIENTATION is deprecated

 

향후에 언제 지원을 멈출지 모르는 불안한 메세지..!

 

방향을 얻기위해서는 TYPE_ACCELEROMETER와 TYPE_MAGNETIC_FIELD를 이용해 이벤트를 등록해야합니다.

 

아래는 샘플코드입니다.
