      }

Any One Please help me to display the Nearest Address of coordinates on infowindow.

Reverse geocoding doesn't work in every country. See the list of functionality coverage provided by Google.

If "Geocoding" says "same as tiles" then only locations identified on the tiles can be geocoded, and reverse geocoding is also limited. Google don't have full details of everywhere in that country.

This applies to Pakistan.

It's also the case that you are not checking the status returned by the geocoder. It gets passed to the callback function and you never use it. It will almost certainly give some hint about what's going on.
