This is a simple implementation of the A* search algorithm on Android and Windows Phone devices.
The application accepts either a map file as input, or just the simple drawings made by the user via UI gestures.

You can find this updated version on Github.
As information for this application, two very good sources on the A* search algorithm were used, namely:
