android - How to implement GPS Status change listener -


in android application sending location update server in each 5 minutes. using gms locationlistener. working fine. running inside service. wont work if user turned off gps. since running in service after turning on gps wait completing 5 minutes of update time. want when user turned on gps should trigger onlocationupdate listener.

for have did follows have initialized gpsstatus.listener in service, , implemented onstatuschange function. after changing gps status on off/ off on ,the function not triggering .

code

    public class locationupdateservice extends service implements gpsstatus.listener, com.google.android.gms.location.locationlistener{         oncreate(bundle b){           super.oncreate();           registergpsstatuslistener();         }          private void registergpsstatuslistener() {          locationmanager locationmanager = (locationmanager) getsystemservice(context.location_service);          locationmanager.addgpsstatuslistener(this);         }          @override         public void ongpsstatuschanged(int event) {             switch (event) {                 case gpsstatus.gps_event_started:                     log.e(tag, "ongpsstatuschanged started");                     break;                  case gpsstatus.gps_event_stopped:                     log.e(tag, "ongpsstatuschanged stopped");                     break;                  case gpsstatus.gps_event_first_fix:                     log.e(tag, "ongpsstatuschanged first fix");                     break;                  case gpsstatus.gps_event_satellite_status:                     log.e(tag, "ongpsstatuschanged status");                     break;             }         }  @override     public void onlocationchanged(location location) {        //opertations     }     }

my queries ;

1- why method ongpsstatuschanged not calling after changing gps status.

2- how location inside onlocationchanged method, can call onlocationupdate method.

note: please not recommend use broadcastreceiver since requires huge code modification of current code

i think trying know when user switches gps on or off device. in case can have @ this answer.this correct , reliable way detect gps on/off switch (at least 1 worked me).

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
