Draw Route Using Current Location From Device On Map Using GPS Provider

I'm working on a project to display a route in a MapView based on current location from GPS Provider. I'm able to draw the path between two points but the problem starts when the location changes to a new point causing the draw path to erase. Basically my Location Listener saves the current Geopoint and sets the new Geopoint location and after that it starts the overlay to draw a path based on those two points. I think an option could be saving the coordinates to a database and then pulling the information from there to draw the path.

private class MyLocationListener implements LocationListener {
public void onLocationChanged(Location location) {
Toast.makeText(getBaseContext(), "Tracking device..",
Toast.LENGTH_SHORT).show();
[code]....
