title: marker show info window on end drag
body: <p>I want the info window of my marker to appear when the marker has been dragged to a point.
  I want the address to appear in it.
  My LogCat gives me the correct address so that works fine, but the infowindow does not show</p>
  
  <p>here's my code</p>
  
  <pre><code>private void placeMarker() {
      getMap().addMarker(new MarkerOptions()
              .position(getMyLocation())
              .draggable(true)
              .snippet("")
              .title(""));
      getMap().setOnMarkerDragListener(new OnMarkerDragListener() {
  
          public void onMarkerDragStart(Marker arg0) {
              // TODO Auto-generated method stub
  
          }
  
          public void onMarkerDragEnd(Marker marker) {
              latLng = marker.getPosition();
              marker.setSnippet("Loading address...");
              marker.showInfoWindow();
  
              Geocoder geoCoder = new Geocoder(getActivity(), Locale.getDefault());
              try {
                  address = geoCoder.getFromLocation(latLng.latitude, latLng.longitude, 1).get(0);
                  String addressString = address.getAddressLine(0);
                  addressString += "\n"+address.getAddressLine(1);
                  marker.setSnippet(addressString);
                  marker.showInfoWindow();
  
                  Log.d("get address pinpoint", "drag end: " + addressString+ " shown:" + marker.isVisible());
              } catch (IOException e) {
                  e.printStackTrace();
              }
  
  
          }
  
          public void onMarkerDrag(Marker arg0) {
              // TODO Auto-generated method stub
  
          }
      });
  
  }
