Android: How to use SensorManager.getAltitude(float p0, float p)?

Question

I found an alternative way to obtain altitude by using SensorManager but it requires two paramaters.

public static float  getAltitude  (float p0, float p)

C         


        

Answer 1

try

List sensors = sensorManager.getSensorList(Sensor.TYPE_PRESSURE);
if(sensors.size() > 0) {


  sensor = sensors.get(0);
  mSensorManager.registerListener(this, sensor, SensorManager.SENSOR_DELAY_NORMAL);

}

 public void onAccuracyChanged(Sensor sensor, int accuracy) {
 }

 public void onSensorChanged(SensorEvent event) {
    presure = event.values[0];
 }

float altitude = getAltitude(SensorManager.PRESSURE_STANDARD_ATMOSPHERE, presure);
