gps - Android LocationListener no hitting onLocationChanged -


i have class named gpstracker implements locationlistener interface. 

public class gpstracker implements locationlistener {     context context;     locationmanager lm;

in constructor set locationmanager , settings (i've omitted permissions part):

public gpstracker(context c) {     context = c;      ... (permission checking)      lm = (locationmanager) context.getsystemservice(context.location_service);     boolean isgpsenabled = lm.isproviderenabled(locationmanager.gps_provider);     if(isgpsenabled){         lm.requestlocationupdates(locationmanager.gps_provider, 6000, 5, this);     } else {         toast.maketext(context, "please enable gps", toast.length_short).show();     } }

in manifest file i've set these permissions gps:

<uses-permission android:name="android.permission.access_fine_location" /> <uses-permission android:name="android.permission.access_coarse_location" />

and i've overridden methods of 1 has functionality, onlocationchanged method:

@override public void onlocationchanged(location location) {     inspectieoverzicht activity = (inspectieoverzicht) context;     activity.getfirstfragment().updatedistance(location); }

i create new gpstracker object in activity.

g = new gpstracker(this);

i expect work. it'll ask permissions use gps , see in top gps icon it's working gps. onlocationchanged method never called.

i tried walking , down building i'm @ (maybe needs change) didn't work.

i've tried on virtual device change gps location , works charm. it's updating activity immediately.

i've tried on api 19, 23 , 26 (on emulated devices) worked. i've tried on api 23 on actual device doesn't seem work.

does knows i'm doing wrong here?

use both network provide coordinates if gps_provider not works

  locationmanager.requestlocationupdates(locationmanager.network_provider, min_time_bw_updates, min_distance_change_for_updates, mylistener);         locationmanager.requestlocationupdates(locationmanager.gps_provider, min_time_bw_updates, min_distance_change_for_updates, mylistener);

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
