I used the solution given by "La bla bla", but I made some little modifications. I was having an issue displaying the path when i had too many points, when you Zoom in too much, the route is not displayed anymore, and you get this message in logcat "shape path too large to be rendered into a texture".

What I did was to subdivide the path in the following way:

if (shadow == false && _points != null) {
        Path path = new Path();;
        //We are creating the path
        Point pointA = new Point();
        for (int i = 0; i < _points.size(); i++) {
            mapView.getProjection().toPixels(_points.get(i), pointA);
            if (i == 0) path.moveTo(pointA.x, pointA.y);                
            else path.lineTo(pointA.x, pointA.y);

            if(i%10==0 || i == _points.size()-1){
                Paint paint = new Paint();
                paint.setAntiAlias(true);
                paint.setColor(_pathColor);
                paint.setStyle(Paint.Style.STROKE);
                paint.setStrokeJoin(Paint.Join.ROUND);
                paint.setStrokeCap(Paint.Cap.ROUND);
                paint.setStrokeWidth(mapView.getZoomLevel()-10);
                paint.setAlpha(200);
                if (!path.isEmpty()) canvas.drawPath(path, paint);
                path = new Path();
                path.moveTo(pointA.x, pointA.y);
            }
        }
    }

I make paths every 10 points, it can be less efficient, but this way you can display the path when the zoom is in high values.
