How to draw smooth / rounded path?

Question

I am creating Paths and adding multi lines in each path by using path.moveTo(x, y) and path.lineTo(x, y). Then canvas.drawPath(path, paint)

Answer 1

You probably don't want to lineTo(c, d) and then immediately moveTo(c, d) which is the same point. If you do this, you won't get a nice corner join on the two line segments, which may look like an ugly gap.

Try removing that moveTo.

Answer 2

Maybe this will create what you want

paint.setColor(color);                    // set the color
paint.setStrokeWidth(size);               // set the size
paint.setDither(true);                    // set the dither to true
paint.setStyle(Paint.Style.STROKE);       // set to STOKE
paint.setStrokeJoin(Paint.Join.ROUND);    // set the join to round you want
paint.setStrokeCap(Paint.Cap.ROUND);      // set the paint cap to round too
paint.setPathEffect(new CornerPathEffect(10) );   // set the path effect when they join.
paint.setAntiAlias(true);                         // set anti alias so it smooths
