How do I use the Android Accelerometer?

Question

I'm trying to build an app for reading the values from the accelerometer on my phone, which supports Android 2.1 only.

How do I read from the accelerometer using 2.1-compatible code?

Start with this:

public class yourActivity extends Activity implements SensorEventListener{  private SensorManager sensorManager;  double ax,ay,az;   // these are the acceleration in x,y and z axis  @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);         sensorManager=(SensorManager) getSystemService(SENSOR_SERVICE);         sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);    }    @Override    public void onAccuracyChanged(Sensor arg0, int arg1) {    }     @Override    public void onSensorChanged(SensorEvent event) {         if (event.sensor.getType()==Sensor.TYPE_ACCELEROMETER){             ax=event.values[0];                     ay=event.values[1];                     az=event.values[2];             }    } }
