var tileOverlay = map.addTileOverlay(options)

(from v2.0.0 to current)
map.addTileOverlay(options, callback);

Demo code

<div id="map_canvas"></div>

var mapDiv = document.getElementById("map_canvas");
var map = plugin.google.maps.Map.getMap(mapDiv, {
  //'mapType' : plugin.google.maps.MapTypeId.NONE,
  'preferences': {
    'zoom': {
      'minZoom': 0,
      'maxZoom': 4
    }
  }
});

var tileOverlay = map.addTileOverlay({
  debug: true,  // draw the debug information on tiles

  opacity: 0.75,  // from 0.0 to 1.0

  // Load image files from the local file path
  getTile: function(x, y, zoom) {
    //return "http://tile.openstreetmap.org/" + zoom + "/" + x + "/" + y + ".png";
    return "../images/map-for-free/" + zoom + "_" + x + "-" + y + ".gif"
  }
});
