I have searched a lot regar

Answer 1

You could be having below causes?

First cause

Location provider is not giving you 0.0 values as latitude and longitude. You are getting what had you define first time. Because, you didn't receive fresh location or getLastKnownLocation() returns null. So latitude and longitude variables keep their first values (0.0)

double latitude;
double longitude;

Second cause

Whenever you call getLocation() method, getLastKnownLocation() method will be doing nothing until onLocationChanged fire! (depending on provider)

@Override
public void onLocationChanged(Location location) {

}

Elaborated for 'depending on provider'

You have requested both gps and network providers.

requestLocationUpdates(LocationManager.NETWORK_PROVIDER ... mLocationListener);
requestLocationUpdates(LocationManager.GPS_PROVIDER ... mLocationListener);

And then has called getLastKnownLocation method for both two providers

locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

Assume that those two providers have returned null. In this case, you need to wait until onLocationChanged method has been fired. Otherwise you will be getting null from getLastKnownLocation method depending on provider

@Override
public void onLocationChanged(final Location location) {

    String providerName =  location.getProvider();

    if(providerName.equals(LocationManager.GPS_PROVIDER)){
        // onLocationChanged method is fired by gps provider.
        // After this point, getLastKnownLocation(); method returns not-null 
        // for LocationManager.GPS_PROVIDER
    }

    if( providerName.equals(LocationManager.NETWORK_PROVIDER)){
        // onLocationChanged method is fired by network provider.
        // After this point, getLastKnownLocation(); method returns not-null 
        // for LocationManager.NETWORK_PROVIDER
    }
}
