How to use Google translate API from code

Question

I am trying to create an app that send a word to translate.google.com, take the result of the translation and display it to the user. I composed the URL but I do not know how to extract the word/phrase from the webpage.

Example pseudo: en is code for english and es is code for spanish

String from = "en";
String to = "es";
String word = "hello"; //this will be user input text really
String URL = "http://www.translate.google.com/#" + from + "/" + to + "/" + word;

Therefore the request URL will look like http://www.translate.google.com/#en/es/hello

I now need to be able to retrieve the information from the result box and place it in a String so I can display it to the user.

Solution

Google translate provide API for retrieving translations. You should use json object and GET request to the google translate server. In this link you can find the official Developer's Guide with code examples.

As now Google translator API is paid, isn't possible to get the result through HTTP request?
