    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        Paint paint = new Paint(Paint.DITHER_FLAG);
        paint.setStyle(Paint.Style.STROKE);
        paint.setStrokeWidth(50);
        paint.setColor(0xFF2287BB);

        paint.setStrokeJoin(Paint.Join.MITER);
        canvas.drawPath(createCornersPath(getWidth()/2 - 500, getHeight()/2 - 500, getWidth()/2  +500, getHeight()/2 + 500, 150), paint);
    }

    private Path createCornersPath(int left, int top, int right, int bottom, int cornerWidth){
        Path path = new Path();

        path.moveTo(left, top + cornerWidth);
        path.lineTo(left, top);
        path.lineTo(left + cornerWidth, top);

        path.moveTo(right - cornerWidth, top);
        path.lineTo(right, top);
        path.lineTo(right , top + cornerWidth);

        path.moveTo(left, bottom - cornerWidth);
        path.lineTo(left, bottom);
        path.lineTo(left + cornerWidth, bottom);

        path.moveTo(right - cornerWidth, bottom);
        path.lineTo(right, bottom);
        path.lineTo(right, bottom - cornerWidth);


        return path;
    }
