android sensors help

I run the following code when getSystemService Ben will collapse.

 
package com.example.switchkeyboard; 



import org.openintents.sensorsimulator.hardware.SensorEvent; 
import org.openintents.sensorsimulator.hardware.SensorEventListener; 
import org.openintents.sensorsimulator.hardware.SensorManagerSimulator; 





import android.os.Bundle; 
import android.app.Activity; 
import android.view.Menu; 


import android.widget.Button; 
import android.widget.TextView; 

public class MainActivity extends Activity {
MyListener myListener; 
Button Open = null; 
Button Close = null; 

org.openintents.sensorsimulator.hardware.Sensor sor = null; 
SensorManagerSimulator imulatorManager; 
TextView textView = null; 
@ Override 
public void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState); 
setContentView (R.layout.activity_main); 

Open = (Button) findViewById (R.id.open); 
Close = (Button) findViewById (R.id.close); 
textView = (TextView) findViewById (R.id.textView); 
/ / SenM = (SensorManager) getSystemService (Context.SENSOR_SERVICE); 
/ / One run here on Ben collapse 
imulatorManager = SensorManagerSimulator.getSystemService (this, SENSOR_SERVICE); 
/ * ImulatorManager.connectSimulator (); 
/ / Sor = imulatorManager.getDefaultSensor (Sensor.TYPE_ACCELEROMETER); 

/ / Sor = (Sensor) imulatorManager.getDefaultSensor (Sensor.TYPE_ACCELEROMETER); 

myListener = new MyListener (); 


Open.setOnClickListener (new Button.OnClickListener () {

@ Override 
public void onClick (View arg0) {
/ / TODO Auto-generated method stub 

imulatorManager.registerListener (myListener, imulatorManager.getDefaultSensor (Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_FASTEST); 

} 

}); 
* / 

} 


class MyListener implements SensorEventListener 
{

public MyListener () {
/ / TODO Auto-generated constructor stub 
} 
@ Override 
public void onSensorChanged (SensorEvent arg0) {
/ / TODO Auto-generated method stub 

textView.setText (arg0.values ​​[0] + ""); 

} 

@ Override 
public void onAccuracyChanged (
org.openintents.sensorsimulator.hardware.Sensor arg0, int arg1) {
/ / TODO Auto-generated method stub 

} 

} 

@ Override 
protected void onPause () {
/ / TODO Auto-generated method stub 
super.onPause (); 
imulatorManager.unregisterListener (myListener); 
} 




@ Override 
public boolean onCreateOptionsMenu (Menu menu) {
getMenuInflater () inflate (R.menu.activity_main, menu);. 
return true; 
} 
} 

Very wonder.
Now no clue. Originally, I would not be a bad environment configuration? But only in SensorManagerSimulator.getSystemService will go wrong?
We also hope to talk about the possibility of

I've added SensorManagerSimulator. The compiler did not complain.
