Rectangle not updating nor showing color

I am having issues with by rectangle not stopping (hard coded values due to bugs with grabbing screen height) in addition, when I draw with red paint, I always get a black rectangle no matter what, any ideas?

If you need more code, let me know.

 public void draw(Canvas canvas){
        Rect rect;
        rect = new Rect(x, y, x + SIZE, y + SIZE);
        Paint paint = new Paint(Color.rgb(250, 0, 0));

       canvas.drawRect(rect, paint);
    }

    public void update(){

        if (this.y < (1920 - SIZE)) {
            this.y += 5;
        } else if (this.y > 1920){
            this.y = 1920 - SIZE;
        }


    }

The Paint(int) constructor doesn't take a color value; those are actually flags.

Just use setColor(int) instead.

If you want it to animate, add a call to invalidate() to your onDraw() routine (doesn't really matter where). That way, it keeps getting redrawn, in an endless cycle. Also, call update() inside onDraw() as well. Kind of a "poor-man's" animation, but it should get you going.
