get city name, address using latitude and longitude in appcelerator - google-maps

Question

I have a doubt in the mentioned Title. I can get current latitude and longitude. But when i am using reverse geoCoding to convert to corresponding city name or address, nothing shows. Does anybody have any idea about this ?. Here is my code
Titanium.Geolocation.getCurrentPosition(function(e) {
if (!e.success || e.error) {
alert('Could not find the device location');
return;
} else {
longitude = e.coords.longitude;
latitude = e.coords.latitude;
Titanium.Geolocation.reverseGeocoder(latitude, longitude, function(e) {
if (e.success) {
var places = e.places;
if (places && places.length) {
driverCity = places[0].city;
// Current city
driverState = places[0].address;
// Current State
annotation.title = e.places[0].displayAddress;
// Whole address
// Ti.API.info("\nReverse Geocode address == " + JSON.stringify(places));
} else {
// address = "No address found";
}
}
});
}
});

I would suggest firstly using different variables for your return parameters in the functions and use negative conditions to reduce indentation:
Titanium.Geolocation.getCurrentPosition(function(position) {
if (!position.success || position.error) {
alert('Could not find the device location');
return;
}
longitude = position.coords.longitude; // -88.0747875
latitude = position.coords.latitude; // 41.801141
Titanium.Geolocation.reverseGeocoder(latitude, longitude, function(result) {
if (!result.success || !result.places || result.places.length == 0) {
alert('Could not find any places.');
return;
}
var places = result.places;
Ti.API.info("\nReverse Geocode address == " + JSON.stringify(places));
driverCity = places[0].city;
// Current city
driverState = places[0].address;
// Current State
annotation.title = places[0].displayAddress;
// Whole address
// Ti.API.info("\nReverse Geocode address == " + JSON.stringify(places));
});
});
Then see what is being returned from your calls.
