Android Camera API
===

I have created a camera API for android. That works fine. Now I am trying to automatically turn on that if accelerometer reading > 2.0 (Gforce > 2.0) I have written a activity to measure the force as well. But that part is not working. (When I check the accelerometer part separately It works fine. But when I add that to the camera project It is not working ) How can I correct this. 
I have refer the below link to make the camera.

And below is my code for accelerometer

    package com.example;
    
    import java.text.DecimalFormat;
    import java.util.Timer;
    import java.util.TimerTask;
    
    
    
    import android.app.Activity;
    import android.content.Context;
    import android.hardware.Sensor;
    import android.hardware.SensorEvent;
    import android.hardware.SensorEventListener;
    import android.hardware.SensorManager;
    import android.os.Bundle;
    import android.widget.TextView;
    
    
    public class Measure extends Activity{
    
    	SensorManager sensorManager;
        TextView current;
    
        
        private double currentAccel= 0.0f;
        private static DecimalFormat REAL_FORMATTER = new DecimalFormat("0.####");
      
        
        private final SensorEventListener sensorEvent = new SensorEventListener(){
            double calibration = SensorManager.STANDARD_GRAVITY;
    
            @Override
            public void onAccuracyChanged(Sensor sensor, int accuracy) {
                   
            }
            @Override
            public void onSensorChanged(SensorEvent event) {
                    double x = event.values[0];
                    double y = event.values[1];
                    double z = event.values[2];
                   
                    double a = Math.round(Math.sqrt(Math.pow(x, 2) + Math.pow(y, 2) + Math.pow(z, 2)));
                    currentAccel = ((float)(a-calibration));
             	
            }
    };
        
        @Override

            current = (TextView)findViewById(R.id.current);
            current.setTextSize(1, 30);
           
            sensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
            Sensor accelerometer = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
            sensorManager.registerListener(sensorEvent, accelerometer, SensorManager.SENSOR_DELAY_FASTEST);
           
            Timer updateTimer = new Timer("gForceUpdate");
            updateTimer.scheduleAtFixedRate(new TimerTask(){
                    public void run() {
                            updateGUI();
                    }
            }, 0, 50);
            
        }
        
        private void updateGUI(){
            runOnUiThread(new Runnable(){
                    @Override
                    public void run() {
    
                    		
                           double currentG = currentAccel / SensorManager.STANDARD_GRAVITY ;
    
                           current.setText(REAL_FORMATTER.format(currentG));
    
                          /* if(currentG>2.3){
                        	   CameraDemo obj = new CameraDemo();
                        	   
                           
                            String acl=Double.toString((Double)currentG);
                            String result=obj.sendAccelerationData(acl);
                            
                            }
                            */
                    }
            });
    }
    
    }
