I thought it would be cool to learn how to program something for yet another platform. Android was the decision. This is simple currency converter (exchange rates).

Solution:

I've build this application using Eclipse, Android SDK and ADT plugin.

Description:

There are basically 3 different screens (as depicted below). First is where all conversions take place. Second is list of all available currencies, and the third is edit/new currency screen. Among main functionalities of this application belongs:

• 4 independent currencies selectors (you can use everyone of them as main)
• updates currencies from European Central Bank, additional sources and RSS feeds
• update scheduler
• onscreen keyboad with big keys
• all rates of currencies selected flashs before your eyes
• favorite currencies (you can select 4 and quickly return to them by loading them)
• possibility to select base currency (all rates in list view are based on this currency)
• select which currencies are updateable (you can decide that you don't want to update some of them)
• select which currencies are available in conversion (by setting ACTIVE status) without deleting them
• insert/update/delete of currencies

update 1.5.0 brought:
