Custom pie chart by drawing circles

I need to do this: Pie chart

I have done this:

I consider my work as great success but still it is not perfect. So could you advice me how to finish it to have it look like the first picture? I need to get rid of some of that lines as you can see. Any idea?

To draw it I have used 3 circles drawArc() method. And used values of degrees from the array.

Even though you don't know the answer you could vote it up since it is hard.

The answer was to draw it as path:

CODE:

if (i == 0) {
            final Path path = new Path();
            paint.setColor(COLORS[i]);
            // draw 3 paths to show 3 curves  
            path.addArc(rectf, 180, value_degree[i] - 4);
            path.addArc(rectf2, 180, value_degree[i] - 5);
            path.addArc(rectf3, 180, value_degree[i] - 6);
            // draw the path
            canvas.drawPath(path, paint);

            // disagree
        } else {
            temp += (int) value_degree[i - 1];
            paint.setColor(COLORS[i]);
            final Path path = new Path();
            path.addArc(rectf, temp + 180 + 4, value_degree[i] - 4);
            path.addArc(rectf2, temp + 180 + 5, value_degree[i] - 5);
            path.addArc(rectf3, temp + 180 + 6, value_degree[i] - 6);
            // draw the path
            canvas.drawPath(path, paint);
        }

RESULT:
