title: How to change a Google Map PolygonOption fill color after its drawn
body: <p>Is there a way to change a PolygonOption's fill color after it has been drawn and update a  Google map without clearing and redrawing it?</p>
  
  <p>What  I'm currently doing is </p>
  
  <pre><code>    polygonOptions.fillColor(context.getResources().getColor(R.color.polygonSolidFill));
      polygonOptions.strokeWidth(2);
      polygonOptions.strokeColor(Color.BLACK);
      // Add some LatLngs 
      googleMap.addPolygon(polygonOptions);
  </code></pre>
  
  <p>When the user is at a certain location I want to change the fill color. What I'm doing to achieve the color update is</p>
  
  <pre><code>    polygonOptions.fillColor(context.getResources().getColor(R.color.polygonSolidFill2));
      googleMap.clear();
      googleMap.addPolygon(polygonOptions);
  </code></pre>
  
  <p>However there is a small flicker in the map when its cleared and redrawn which I would like to avoid.</p>
