android - Why doesn't onLocationChanged method get called in service? -


i getting current location in form of latitudes , longitudes. problem once coordinates doesn't updated when move location.i think onlocationchanged method not getting called. read here http://www.lengrand.fr/2013/10/onlocationchanged-is-never-called-on-android/ doesn't called itself. have gone through of tutorials , can't find solution.so how can call onlocationchanged method in service. please suggest me step step.

my codes follow:

  public   class gpstracker extends service implements locationlistener {  public location getlocation() {     try {         locationmanager = (locationmanager) mcontext                 .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, this);                 log.d("network", "network");                 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, this);                     log.d("gps enabled", "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();     }      return location; } }                 @override public void onlocationchanged(location location) {      getlocation();  }

  • make sure requestlocationupdates(...) locationmanager (which in case seems do)
  • if inside building , device doesn't gps fix onlocationchanged(...) not called, had same issue (when debugging in home) going outside saw function called once gps fix retrieved.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
