        if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
            CropImage.ActivityResult result = CropImage.getActivityResult(data);
        //크롭 성공시 
            if (resultCode == RESULT_OK) {
                ((ImageView) findViewById(R.id.quick_start_cropped_image)).setImageURI(result.getUri());
