Final Version! This is the last update of this application. Because the website that obtains the exchange rate begins to charge, and this application is time consuming for crawling on the mobile phone, the experience is not good and the application is abandoned. Next, we will use Ruby on Rails to overwrite a service for crawling data and pushing information. This application will also be rewritten. Thanks for downloading!
