This app was written as a toll calculator for toll roads in Melbourne, with the ability to add tolls for anywhere else.
It can download updated tolls from a website (url removed, as it is no longer active).
I hope that you find this code useful.
To compile the app you will need the following libraries: ActionBarSherlock - version 4.4.0 : http://actionbarsherlock.com/ Google Play Services Lib
Google Maps part of the app will require your own api key, which can be set in the AndroidManifest.xml
