Hi!!

I'm drawing a route while the user in tapping on screen; it is possible to delete the last point been tapped? I saving every point that has been tapped on an ArrayList<Point>.

To draw the route, I use this method:

public Geometry drawRoute(ArrayList<Point> addPoint, int value){

    PointCollection points = new PointCollection(addPoint, SpatialReferences.getWgs84());
    Polyline polyline = new Polyline(points);

    // densify the path as a geodesic curve and show it with the path graphic
    Geometry pathGeometry = GeometryEngine
            .densifyGeodetic(polyline, 1, mUnitOfMeasurement, GeodeticCurveType.GEODESIC);
    path1.setGeometry(pathGeometry);

    return pathGeometry;
}

Thanks...
