[Android] Anyone who used Yahoo! Weather API?

@Override
            protected String doInBackground(String... strings) {

                //Yahoo query statement
                String YQL = String.format("select * from weather.forecast where woeid in (select woeid from geo.places(1) where text=\"%s\") and u='c'", strings[0]);

                //Yahoo API using Yahoo query statement
                String endpoint = String.format("https://query.yahooapis.com/v1/public/yql?q=%s&format=json", Uri.encode(YQL));

                try {
                    URL url = new URL(endpoint);
                    //Network access using Yahoo API
                    URLConnection connection = url.openConnection();

                    InputStream inputStream = connection.getInputStream();

                    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
                    StringBuilder result = new StringBuilder();
                    String line;
                    while((line = reader.readLine()) != null)
                    {
                        result.append(line);
                    }

                    return result.toString();

                } } catch (Exception e) {
                    error = e;
                }

                return null;
            }
