Android: How to initialize a variable of type "Location" (other than making it equal to null)

The API documentation is quite clear on this. First create a new Location instance:

Location loc = new Location("dummyprovider");

And then use the setter methods to set the location parameters you need, e.g.:

loc.setLatitude(20.3);
loc.setLongitude(52.6);

Location object = new Location("service Provider");

it will create an object of Type Location that contains the initial Latitude and Longitude at location '0' to get the initial values use

double lat = object.getLatitude();
double lng = object.getLongitude();

In Kotlin using LocationManager class you can pass the required location provider like:

val location = Location(LocationManager.NETWORK_PROVIDER) // OR GPS_PROVIDER based on the requirement
location.latitude = 42.125
location.longitude = 55.123
