Get String from Location Android -

i found great function gives me possibility location quickly. after want display (longitude , latitude) doest work still 0.0 / 0.0.

here's code

what should if want display latitude , longitude i'm interested in function getlastknownlocation because want display data without using gps or internet

public class mainactivity extends activity implements onclicklistener 

{

private static final long min_time_bw_updates = 0; private static final float min_distance_change_for_updates = 0; public edittext lokalizacja; public button pobierz; private static context context; locationmanager locationmanager;  // flag gps status boolean isgpsenabled = false;  // flag network status boolean isnetworkenabled = false;  // flag gps status boolean cangetlocation = false;  location location; // location double latitude ; // latitude double longitude; // longitude    public static context getcontext() {     return context; }   @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     lokalizacja = (edittext) findviewbyid(r.id.edittext1);     pobierz = (button) findviewbyid(r.id.button1);       pobierz.setonclicklistener(this);  }   @override public void onclick(view v) {         getlocation();    }   public location getlocation() {     try {         locationmanager = (locationmanager) context.getsystemservice(location_service);          // getting gps status         isgpsenabled = locationmanager                 .isproviderenabled(locationmanager.gps_provider);          // getting network status         isnetworkenabled = locationmanager                 .isproviderenabled(locationmanager.network_provider);          if (!isgpsenabled && !isnetworkenabled) {             // no network provider enabled         } else {             this.cangetlocation = true;              if (isnetworkenabled) {                 locationmanager.requestlocationupdates(                         locationmanager.network_provider,                         min_time_bw_updates,                         min_distance_change_for_updates, (locationlistener) this);                 log.d("network", "network enabled");                 if (locationmanager != null) {                     location = locationmanager                             .getlastknownlocation(locationmanager.network_provider);                     if (location != null) {                         latitude =  location.getlatitude();                          longitude = location.getlongitude();                       }                 }             }             // if gps enabled lat/long using gps services             if (isgpsenabled) {                 if (location == null) {                     locationmanager.requestlocationupdates(                             locationmanager.gps_provider,                             min_time_bw_updates,                             min_distance_change_for_updates, (locationlistener) this);                     log.d("gps", "gps enabled");                     if (locationmanager != null) {                         location = locationmanager                                 .getlastknownlocation(locationmanager.gps_provider);                         if (location != null) {                              latitude = location.getlatitude();                             longitude = location.getlongitude();                          }                     }                 }             }         }      } catch (exception e) {         e.printstacktrace();     }      string napis = string.valueof(latitude+ "\n" + longitude);       lokalizacja.settext(napis);     return location;  }   

}

as flow never enter else part due following condition

 if (!isgpsenabled && !isnetworkenabled) {             // no network provider enabled          } else {  

you need have condition this

 if (!isgpsenabled || !isnetworkenabled) {             // no network provider enabled          } else {  

or first check gps , after network
