There's no need to convert to JSON first - there are some great XML parsers and example code you can use! Check out the information on the Android developer site about parsing XML data.

The documentation there is a little overwhelming, so this helpful answer on StackOverflow might help you, too.

Hope this helps! If you get stuck along the way, feel free to post more questions in the forum here!

I plugged your code into a temp project and I think all you need to do to get the parsing working is change == to .equals() for your String comparisons:

                case XmlPullParser.START_TAG:
                    name = parser.getName();
                    if (name.equals("product")){
                        currentProduct = new Product();
                    } else if (currentProduct != null){
                        if (name.equals("productname")){
                            currentProduct.name = parser.nextText();
                        } else if (name.equals("productcolor")){
                            currentProduct.color = parser.nextText();
                        } else if (name.equals("productquantity")){
                            currentProduct.quantity= parser.nextText();
                        }
                    }
                    Log.i(TAG, "Node parsing");
                    break;

This allows the data to get printed to the log. There is a separate issue at that point with the following lines, but I'm not sure what your intent (pardon the pun) is with these lines. I just commented it out to make sure the parsing worked and was logged.

Intent intent = getIntent();
//String data = intent.getExtras().getString("title");
//textView.setText(data);
