How to Get Geolocation Through Apex Class in Salesforce

We have given the solution for how to get Geo location value in the record. Geo location field is available now in Salesforce. Geo location field includes latitude and longitude values. The below example is shown whenever you update billing street, city, state, a country in account object, it will automatically update geolocation value in the record.

Prerequisite :-

1) Create Geolocation Field type in an Object,

2) Create Remote Site for Google Map API,

Trigger –

trigger AccountAddressTrigger on Account (after insert,after update) {

Set<Id> li=new Set<Id>();

if(Trigger.isAfter && Trigger.isUpdate){

for(Account acc:Trigger.New){

if(acc.Geo__Latitude__s ==null){

li.add(acc.id);

LocationCallouts.newAccmethod(li);

}

}

}

}
Apex Class :-

public class LocationCallouts {

@future(callout=true)
static public void newAccmethod(set<id> li){

for(Account a : [SELECT BillingCity,BillingCountry,BillingPostalCode,BillingState,BillingStreet FROM Account WHERE id =: li]){

String address = ”;

if (a.BillingStreet != null)

address += a.BillingStreet +’, ‘;

if (a.BillingCity != null)

address += a.BillingCity +’, ‘;

if (a.BillingState != null)

address += a.BillingState +’ ‘;

if (a.BillingPostalCode != null)

address += a.BillingPostalCode +’, ‘;

if (a.BillingCountry != null)

address += a.BillingCountry;

address = EncodingUtil.urlEncode(address, ‘UTF-8’);

// build callout

Http h = new Http();

HttpRequest req = new HttpRequest();

req.setEndpoint(‘http://maps.googleapis.com/maps/api/geocode/json?address=’+address+’&sensor=false’);

req.setMethod(‘GET’);

req.setTimeout(5000);
try{

// callout

HttpResponse res = h.send(req);

// parse coordinates from response

JSONParser parser = JSON.createParser(res.getBody());

double lat = null;

double lon = null;

while (parser.nextToken() != null) {

if ((parser.getCurrentToken() == JSONToken.FIELD_NAME) &&

(parser.getText() == ‘location’)){

parser.nextToken(); // object start

while (parser.nextToken() != JSONToken.END_OBJECT){

String txt = parser.getText();

parser.nextToken();

if (txt == ‘lat’)

lat = parser.getDoubleValue();

else if (txt == ‘lng’)

lon = parser.getDoubleValue();

}

}

}

// update coordinates if we get back

if (lat != null){

system.debug(lat+’ ‘+lon);

a.Geo__Latitude__s = lat;
system.debug(a.Geo__Latitude__s+’a.Geo__Latitude__s’);

a.Geo__Longitude__s = lon;
system.debug(a.Geo__Longitude__s +’a.Geo__Longitude__s’);
update a;

}

}

catch (Exception e) {

system.debug(e);

}

}

}

}
