with android pretty easy in order location gps service. utilize locationmanager easiest way it

locationmanager = (locationmanager)getsystemservice(context.location_service); customlocationlistener = new customlocationlistener(); locationmanager.requestlocationupdates( locationmanager.gps_provider, 0, 0, ll);

....a spagehtti code goes here.....

class customlocationlistener implements locationlistener{ ............ public void onlocationchanged(location arglocation) { if(location != null) { int latitude=(int)(arglocation.getlatitude()*1e6); int longitude=(int)(arglocation.getlongitude()*1e6); } } ........ }

might check location android api , android development

android latitude-longitude
