Practical exercises to ensure that the basis of the chapter has been understood
The assignment is mandatory for a passing grade in the course.
Create an app with a home screen widget that displays the current rate of a currency you choose (and what primary currency to relate the rate to). Fetch the rate from a web API or web page. If you have some other piece of information that you'd like to display instead, that is fine too. The criteria for the app is that it fetches a value over the network and displays it in a home screen widget at some interval.
Perform this optional assignment to get one (1) extra credit.
Extend the previous Currency Rate app with new functionality for better customization and notification support.
