Any code will be realy appereciated.
Thanks.

Edit:
I am using this Code to captured and Save the Image So, How shoud i have to Implement Such things.

takePhotoBtn.setOnClickListener(new OnClickListener() {
        public void onClick(View v) { // <5>

            ImageCaptureCallback iccb = null;

            try {
                String filename = timeStampFormat.format(new Date());
                ContentValues values = new ContentValues();
                values.put(Media.TITLE, filename);
                values.put(Media.DESCRIPTION, "Image capture by camera");
                Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);

                iccb = new ImageCaptureCallback( getContentResolver().openOutputStream(uri));

                // to put the Image on captured image.
                Canvas canvas = new Canvas();
                Bitmap kangoo = BitmapFactory.decodeResource(getResources(),
                        R.drawable.icon);
                canvas.drawColor(Color.argb(160, 21, 140, 21));
                canvas.drawBitmap(kangoo, 130, 10, null);


            } catch(Exception ex ){
                ex.printStackTrace();
                Log.e(getClass().getSimpleName(), ex.getMessage(), ex);
            }
          camera.takePicture(mShutterCallback, mPictureCallbackRaw, iccb);
        }
      });


Camera.PictureCallback mPictureCallbackRaw = new Camera.PictureCallback() {
    public void onPictureTaken(byte[] data, Camera c) {
        Log.e(getClass().getSimpleName(), "PICTURE CALLBACK RAW: " + data);
            System.out.println("\n\n\n\nThe Data in mPictureCallbackRaw is :"+data);
        //camera.startPreview(); // Added StastPreview();
    }
};

Camera.PictureCallback mPictureCallbackJpeg= new Camera.PictureCallback() {
    public void onPictureTaken(byte[] data, Camera c) {
        Log.e(getClass().getSimpleName(), "PICTURE CALLBACK JPEG: data.length = " + data);
        System.out.println("\n\n\n\nThe Data in mPictureCallbackJPEG is :"+data);
        camera.startPreview();
    }
};

Camera.ShutterCallback mShutterCallback = new Camera.ShutterCallback() {
    public void onShutter() {
        Log.e(getClass().getSimpleName(), "SHUTTER CALLBACK");
    }
};




public class ImageCaptureCallback implements PictureCallback  {

private OutputStream filoutputStream;
public ImageCaptureCallback(OutputStream filoutputStream) {
    this.filoutputStream = filoutputStream;
}
@Override
public void onPictureTaken(byte[] data, Camera camera) {
    try {
        Log.v(getClass().getSimpleName(), "onPictureTaken=" + data + " length = " + data.length);

        filoutputStream.write(data);
        filoutputStream.flush();
        filoutputStream.close();


    } catch(Exception ex) {
        ex.printStackTrace();
    }
}

}

Try this to combine the two Bitmaps the Camera Image and Transparent Image. This is combine of the images and store in the SDCard.

public Bitmap combineImages(Bitmap c, Bitmap s) {

        Bitmap cs = null;
        int width, height = 0;

        if (c.getWidth() > s.getWidth()) {
            width = c.getWidth();
            height = c.getHeight();
        } else {
            width = s.getWidth() + s.getWidth();
            height = c.getHeight();
        }

        cs = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

        Canvas comboImage = new Canvas(cs);

        comboImage.drawBitmap(c, 0, 0, null);
        comboImage.drawBitmap(s, 100, 300, null);

        /******
         * 
         *   Write file to SDCard
         * 
         * ****/

        String tmpImg = String.valueOf(System.currentTimeMillis()) + ".png";
        OutputStream os = null;
        try {
            os = new FileOutputStream(Environment.getExternalStorageDirectory()
                    + "/"+tmpImg);
            cs.compress(CompressFormat.PNG, 100, os);
        } catch (IOException e) {
            Log.e("combineImages", "problem combining images", e);
        }
        return cs;
    }
