The application allows tracing of your bike on google map when you are on a trip with your bike. The traces are drawn with red line which is in contrast with the map color. The main view of "Bike Trace" consists of two parts - map and informational fields. On the informational fields are shown "trip duration", "GPS precision of your current location", "availability of GPS signal", "current speed", "average trip speed" and "traveled trip distance". The button "Info View" hides the map, and shows only important informational fields. When you are ready to begin your trip, press the "Start" button. When you are finished with your trip, press the "Stop" button. When the trip is stopped, the travelled path is stored in a file in the external storage of your Android device in "kml" format, which can be viewed with Google Earth or Google Maps. Pressing the "Back" button hides the application while leaving it tracking your GPS coordinates.
