my code

public class mainactivity extends activity implements locationlistener, onclicklistener{  locationmanager locationmanager ; string provider; button btn; private string stradd;  @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     btn = (button)findviewbyid(r.id.button1);      btn.setonclicklistener(this);     // getting locationmanager object     locationmanager = (locationmanager)getsystemservice(context.location_service);      // creating empty criteria object     criteria criteria = new criteria();      // getting name of provider meets criteria     provider = locationmanager.getbestprovider(criteria, false);      if(provider!=null && !provider.equals("")){          // location given provider         location location = locationmanager.getlastknownlocation(provider);          locationmanager.requestlocationupdates(provider, 10, 30, this);          if(location!=null)             onlocationchanged(location);         else             toast.maketext(getbasecontext(), "location can't retrieved", toast.length_short).show();      }else{         toast.maketext(getbasecontext(), "no provider found", toast.length_short).show();     } }    @override public void onlocationchanged(location location) {     // getting reference textview tv_longitude     textview tvlongitude = (textview)findviewbyid(r.id.textview1);     textview tvadd  = (textview)findviewbyid(r.id.textview2);      // getting reference textview tv_latitude     //textview tvlatitude = (textview)findviewbyid(r.id.tv_latitude);      // setting current longitude     double lat = location.getlatitude();     double lng = location.getlongitude();      log.e("latlng", ""+lat+lng);    geocoder geocoder = new geocoder(mainactivity.this, locale.getdefault());     try{          list<address> addresses = geocoder.getfromlocation(lat,lng, 1);           if (addresses != null) {               address returnedaddress = addresses.get(0);               stringbuilder strreturnedaddress = new stringbuilder("");                (int = 0; < returnedaddress.getmaxaddresslineindex(); i++) {                   strreturnedaddress.append(returnedaddress.getaddressline(i)).append("\n");               }                 stradd = strreturnedaddress.tostring();            }     }           catch (exception e) {             // todo: handle exception            e.printstacktrace();           }     tvlongitude.settext("lat lng:" + lat+lng);      tvadd.settext("address:" + stradd);      // setting current latitude    // tvlatitude.settext("latitude:" + location.getlatitude() ); }  @override public void onproviderdisabled(string provider) {     // todo auto-generated method stub }  @override public void onproviderenabled(string provider) {     // todo auto-generated method stub }  @override public void onstatuschanged(string provider, int status, bundle extras) {     // todo auto-generated method stub } 

permissions

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

if you're getting 0 value in lat long think you're unable receive gps response. gps might take lot of time first fix upto 15 minutes depending on visibility of satellites. so, when you're using gps make sure you're in outdoor location faster fix.

also, you'll need include <uses-permission android:name="android.permission.internet" /> since geocoder need send lat lng online servers address.
