android - LocationServices.FusedLocationApi.getLastLocation(googleApiClient) is always null on emulator -

i don't know whats wrong emulator. can't take locatioan command

locationservices.fusedlocationapi.getlastlocation(googleapiclient) 

in emulator supported gps , google play service nothing works taking current locaion. location = null. need help. here code :

  private void configuregoogleapiclient() {         locationrequest = locationrequest.create();         locationrequest.setpriority(locationrequest.priority_high_accuracy);         locationrequest.setinterval(constant.interval);         locationrequest.setfastestinterval(constant.fastinterval);          googleapiclient = new googleapiclient.builder(this)                 .addapi(locationservices.api)                 .addconnectioncallbacks(this)                 .addonconnectionfailedlistener(this)                 .build();         if (googleapiclient != null) {             googleapiclient.connect();         }     }      @override     protected void onstart() {         super.onstart();         if (googleapiclient != null) {             googleapiclient.connect();         }     }      protected void onstop() {         // disconnecting client invalidates it.         if (googleapiclient != null) {             googleapiclient.disconnect();         }         super.onstop();     }       @override     protected void onpause() {         super.onpause();         if (googleapiclient != null) {             googleapiclient.disconnect();         }     }      @override     protected void onresume() {         super.onresume();         if (manager.isproviderenabled(locationmanager.gps_provider)) {             if (googleapiclient != null)                 googleapiclient.connect();         }     }      @override     public void onconnected(@nullable bundle bundle) {         if (googleapiclient.isconnected()) {             log.e(mainactivity.class.getsimplename(), "is connected");         } else             log.e(mainactivity.class.getsimplename(), "is not connected");          if (manager.isproviderenabled(locationmanager.gps_provider)) {             log.e(mainactivity.class.getsimplename(), "is connected on gps");         } else {             log.e(mainactivity.class.getsimplename(), "is not connected on gps");         }          utility.checkpermission(this);         location = locationservices.fusedlocationapi.getlastlocation(googleapiclient);          if (location == null) {             utility.checkpermission(this);             locationservices.fusedlocationapi.requestlocationupdates(googleapiclient, locationrequest, this);         }          if (location != null) {             lattext.settext("lat: " + string.valueof(location.getlatitude()));             longtext.settext("long: " + string.valueof(location.getlongitude()));         } else {             lattext.settext(getstring(r.string.error_find_location));             longtext.settext(getstring(r.string.error_find_location));         }     }      @override     public void onconnectionsuspended(int i) {      }      @override     public void onconnectionfailed(@nonnull connectionresult connectionresult) {         log.e(mainactivity.class.getsimplename(), connectionresult.tostring());     }      @override     public void onlocationchanged(location location) {         currentlocation = location;         if (googleapiclient != null)             if (googleapiclient.isconnected() || googleapiclient.isconnecting()) {                 googleapiclient.disconnect();                 googleapiclient.connect();             } else if (!googleapiclient.isconnected()) {                 googleapiclient.connect();             }         string msg = "updated location: " + double.tostring(location.getlatitude()) + "," + double.tostring(location.getlongitude());         toast.maketext(this, msg, toast.length_short).show();         configureview();     } 

my guess last location shows last location. doesn't try figure out location. on phone app requested location. so, there last location.

i've added code request location if there none.

location userlocation = locationservices.fusedlocationapi.getlastlocation(googleapiclient); if (userlocation == null) {     locationrequest locationrequest = new locationrequest();     locationrequest.setnumupdates(1);     locationrequest.setinterval(0);     locationrequest.setpriority(priority_high_accuracy);     locationservices.fusedlocationapi.requestlocationupdates(             googleapiclient, locationrequest,             new locationlistener() {                 @override                 public void onlocationchanged(location location) {                     locationservices.fusedlocationapi.removelocationupdates(                             googleapiclient,                             this);                 }             });
