Yes we cam...try this

LocationManager manager = (LocationManager) Context.getSystemService(Context.LOCATION_SERVICE);
manager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

// additionally (you have to implement LocationListener)
manager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0.0f, new LocationListener() ...)

After location you can use in locationlistener...

 @Override
    public void onLocationChanged(Location location) {                          
         Log.d("a","onLocationChanged: lat="+location.getLatitude());
         Log.d("a","onLocationChanged: lat="+location.getLongitude());                 
    }

hope it helps..

  • I am not getting the coordinates... Is there some other way to obtain coordinates without using Locationmanager? – coderslay Apr 02 '11 at 04:42
  • I got the coordinates by GPS but when i use NETWORK_PROVIDER then my tablet shows me that there is no provider available(while wifi is available on tablet)... and my android mobile doesnt show anything(it doesnt override any of the functions)....... – coderslay Apr 02 '11 at 05:31

Yes you can. Have a look at the documentation

When you have a Location from the system. you can use methods getLongitude() and getLatitude()

For a full example have a look at this code - lines 122-124 to set up receiving updates and lines 201-209 to get the Location.

  • Hello Heiko... i used ur code like Location location = getCurrentLocation(); which calls the getCurrentLocation(); and through this i am getting location value as null...i just have wifi enabled on my mobile... – coderslay Apr 01 '11 at 06:23
  • Did you also start receiving location updates - as set up in lines 122-124 and as @Udaykiran has indicated in its first source listing in his answer? – Heiko Rupp Apr 01 '11 at 07:43
