I want to send every 15minute updated latitude and longitude of android device to php web service. How can i do this?
For sending lat, long to webservice I think you can use either service or any thread in which you put the timer for every 15 minutes from device time and at that point just fetch the lat,long and send it to the your web service.
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
from this method you get the update at specified time interval and frequency.
Here is the Android Location Manager link try it.
