android - Request location updates not updating while driving -
i have written function requesting location updates:
private void requestlocations() { locationlistener = new locationupdater(); lm = (locationmanager) getsystemservice(context.location_service); if (!lm.isproviderenabled(locationmanager.gps_provider)) { lm.requestlocationupdates(locationmanager.network_provider,0, 100, locationlistener); } else { lm.requestlocationupdates(locationmanager.gps_provider, 0, 100, locationlistener); lm.requestlocationupdates(locationmanager.network_provider,0, 100, locationlistener); } } i calling function in onstart() of service have made foreground service. in locationupdater have implemented locationlistener. in on location changed toasting lat/lang. working fine if @ walking speed. while driving not accurate , fast walking speed. though not toasting location if @ speed of more 50 km/h , stop again starts working , toast new location. wanted make in move 100 meters away should toast new location whatever speed is. please guide me , if wrong @ place make me correct.
try these code....it can helpful you
