I am using Android Studio in order to build a sample of a mobile banking app. In this mobile application, I need to transfer amounts of money from one account to the other. At some point, if the accounts have different currencies, I need to convert the amount to be transferred to the amount that corresponds with the currency needed. For example, if I am transferring 200$ from one account to another in euros, I need to multiply that amount with the rate of the receiving account just like this: 200*1.13=226€. For now, I have been using default values for the rates. The tricky part is that currency rates are constantly changing so I need to keep it up to date. I suppose that I should retrieve the information I need from another source like a website, but I have no idea how to do so. Any help would be welcome. Thanks in advance.

You can use currency convertor api's. For eg:

http://jsonrates.com/docs/

Get your API key, and pass in this url along with the currencies

Request: http://jsonrates.com/get/?from=USD&to=EUR&apiKey=YOUR_API_KEY
