        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            System.out.println("requestCode" + requestCode);
            if (requestCode == 2) {
                Uri uri = data.getData();
                ContentResolver cr = this.getContentResolver();
                try {
                    Bitmap bmp = BitmapFactory.decodeStream(cr
                            .openInputStream(uri));
