For Java Android Studio, I need to display the address given the latitude and longitude (which I obtained in the onLocationChanged method). I tried the following method:

---------------------------------------------------------------------------------------------------------------------------------------------

public String getAddress(Context ctx, double lat, double lng){    String fullAdd=null;    try{        Geocoder geocoder= new Geocoder(ctx, Locale.getDefault());        List addresses = geocoder.getFromLocation(lat, lng, 1);        if(addresses.size()>0){            Address address = addresses.get(0);            fullAdd = address.getAddressLine(0);         }    }catch(IOException ex){        ex.printStackTrace();    }    return fullAdd; }

---------------------------------------------------------------------------------------------------------------------------------------------------

After that, in my onLocationChanged, I set a textview's text to

getAddress(this, location.getLatitude(), location.getLongitude()); 

However, I keep getting null for the address. How do I fix this and make it diplay the address given the latitude and longitude?
