/**
 * The Google Maps Image APIs make it easy to embed a static Google Maps image into your image view.
 * @param location - The location (such as 40.457375,-80.009353).
 * @param zoomLevel - (required if markers not present) defines the zoom level of the map, which determines the magnification level of the map.
 * This parameter takes a numerical value corresponding to the zoom level of the region desired.
 * @param imageWidth - Specifies width size of the image in pixels.
 * @param imageHeight - Specifies height size of the image in pixels.
 * @param imageScale - (optional) affects the number of pixels that are returned. scale=2 returns twice as many pixels as scale=1 while retaining the same coverage area and level of detail (i.e. the contents of the map don't change).
 * This is useful when developing for high-resolution displays, or when generating a map for printing. The default value is 1.
 * @param mapType - (optional) defines the type of map to construct. There are several possible maptype values, including roadmap, satellite, hybrid, and terrain. Use LPGoogleMapType.
 * @param markers - (optional) define one or more markers to attach to the image at specified locations. This parameter takes a single marker definition with parameters separated by the pipe character (|).
 * Multiple markers may be placed within the same markers parameter as long as they exhibit the same style; you may add additional markers of differing styles by adding additional markers parameters.
 * Note that if you supply markers for a map, you do not need to specify the (normally required) center and zoom parameters. Use LPMapImageMarker.
 * @param responseHandler//from ww w.j a  v a  2s  .c  o m
 * @Override public void willLoadStaticMapImage()
 * @Override public void didLoadStaticMapImage(Bitmap bmp)
 * @Override public void errorLoadingStaticMapImage(Throwable error)
