问题
I'm trying to develop a simple Forex app for Android. To start off, I need to get the currency exchange rates, say for the past year.
Could anybody advice how I can go about this? I looked in Google financh API but couldn't find how to retrieve currency rates. Any advice is appreciated.
Thank you.

You can parse the data from the federal reserve. It has historical data separated by country. You can find the link here:
http://www.federalreserve.gov/releases/h10/Hist/
Data is given in plain ascii, making it very easy to parse.

You could access some Foreign Exchange company APIs and get access to realtime and historical data of a range of currency pairs.
Oanda provide an API : http://fxtrade.oanda.com/trade-forex/api/
Interactive Brokers provide one also : http://www.interactivebrokers.com/en/p.php?f=programInterface&p=
XE have a data feed service: http://www.xe.com/ict/
