Drawing an acute angle heart in Android

Question

The following question may seem a little silly, but I think stupidity has no limit, so here it is. I draw a Heart using Canvas on Android, and I have no problem drawing a heart, but I cannot make my heart sharp in the meeting place. My heart looks like

CODE:

            left_x_moveto = 200;
            left_y_moveto = 45;

            left_x1 = 197;
            left_y1 = -35;
            left_x2 = 60;
            left_y2 = 20;
            left_x3 = 193;
            left_y3 = 130;

            right_x_moveto = 200;
            right_y_moveto = 45;

            right_x1 = 197;
            right_y1 = -35;
            right_x2 = 345;
            right_y2 = 20;
            right_x3 = 193;
            right_y3 = 130;



           heart_outline_paint.setColor(getResources().getColor(R.color.heart_outline_color)); // Change the boundary color
        heart_outline_paint.setStrokeWidth(15);
        heart_outline_paint.setStyle(Paint.Style.STROKE);

        path.moveTo(left_x_moveto, left_y_moveto);
        path.cubicTo(left_x1, left_y1, left_x2, left_y2, left_x3, left_y3);

        path.moveTo(right_x_moveto, right_y_moveto);
        path.cubicTo(right_x1, right_y1, right_x2, right_y2, right_x3, right_y3);
        canvas.drawPath(path, heart_outline_paint);

What I have tried so far:

• The decrease or increase in points left_x_moveto, left_y_movetoand vice versa, but the heart is completely disfigured, for which I can not find a reason.

When right_x_moveto = 198and right_y_moveto = 45, the heart looks like

I am not sure why this is happening.

2. Reducing the width heart_outline_paintwill give me what I want, but I want the thickness of the heart to be the same, so reducing is setStrokeWidthnot an option.
