Android Camera Orientation for Beginners

I am working with a camera and a problem in camera orientation . I found some answer over the internet and I think this answer might be the best for me.

Can someone give me detailed instructions on how to add this answer to my camera project.

Here is my Full Camera Project Code .

Direct code here

public class AndroidCamera extends Activity implements SurfaceHolder.Callback{

 Camera camera;
 SurfaceView surfaceView;
 SurfaceHolder surfaceHolder;
 boolean previewing = false;
 LayoutInflater controlInflater = null;

 Button buttonTakePicture;



 final int RESULT_SAVEIMAGE = 0;

   /** Called when the activity is first created. */
   @SuppressWarnings("deprecation")
@Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);


       getWindow().setFormat(PixelFormat.UNKNOWN);
       surfaceView = (SurfaceView)findViewById(R.id.camerapreview);
       surfaceHolder = surfaceView.getHolder();
       surfaceHolder.addCallback(this);
       surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);


       controlInflater = LayoutInflater.from(getBaseContext());
       View viewControl = controlInflater.inflate(R.layout.control, null);
       LayoutParams layoutParamsControl
        = new LayoutParams(LayoutParams.FILL_PARENT,
        LayoutParams.FILL_PARENT);
       this.addContentView(viewControl, layoutParamsControl);


       buttonTakePicture = (Button)findViewById(R.id.takepicture);
       buttonTakePicture.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub
    camera.takePicture(myShutterCallback,
      myPictureCallback_RAW, myPictureCallback_JPG);
   }});

       LinearLayout layoutBackground = (LinearLayout)findViewById(R.id.background);
       layoutBackground.setOnClickListener(new LinearLayout.OnClickListener(){


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

    buttonTakePicture.setEnabled(false);
    camera.autoFocus(myAutoFocusCallback);
   }});
   }

   AutoFocusCallback myAutoFocusCallback = new AutoFocusCallback(){

  @Override
  public void onAutoFocus(boolean arg0, Camera arg1) {

  }};

   ShutterCallback myShutterCallback = new ShutterCallback(){

  @Override
  public void onPictureTaken(byte[] arg0, Camera arg1) {
   // TODO Auto-generated method stub
   /*Bitmap bitmapPicture
    = BitmapFactory.decodeByteArray(arg0, 0, arg0.length); */

   Uri uriTarget = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, new ContentValues());

   OutputStream imageFileOS;
   try {
    imageFileOS = getContentResolver().openOutputStream(uriTarget);
    imageFileOS.write(arg0);
    imageFileOS.flush();
    imageFileOS.close();

    Toast.makeText(AndroidCamera.this,
      "Image saved",
      Toast.LENGTH_SHORT).show();

   } catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }

   camera.startPreview();
  }};

 @Override
 public void surfaceChanged(SurfaceHolder holder, int format, int width,
   int height) {
  // TODO Auto-generated method stub
  if(previewing){
   camera.stopPreview();
   previewing = false;
  }

  if (camera != null){
   try {
    camera.setPreviewDisplay(surfaceHolder);  
    camera.startPreview();
    previewing = true;
   } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
  }
 }



 @Override
 public void surfaceCreated(SurfaceHolder holder) {
  // TODO Auto-generated method stub
  camera = Camera.open();
 }

 @Override
 public void surfaceDestroyed(SurfaceHolder holder) {
  // TODO Auto-generated method stub
  camera.stopPreview();
  camera.release();
  camera = null;
  previewing = false;
 }
