How to show information when I will come in a range of created location

Question

Sorry if my question could be "silly" but I am new Android programmer. I've wrote the app based on that example: http://developer.android.com/training/location/receive-location-updates.html Everything works fine. It show my current location and I receive location updates. I've added a specific location. When I come in a range of that location only show the text "ERROR".
What I did wrong?

public void firstLocation (View v) {
      final Location loc = new Location ("");
      loc.setLatitude(47.2175723);
      loc.setLongitude(17.1427797);
      loc.setAccuracy(10);

      if (mLocationClient.getLastLocation() == loc) {
              Toast.makeText(this, "SOME INFORMATION",
                    Toast.LENGTH_SHORT).show();
          }
       else
          Toast.makeText(this, "ERROR",
                    Toast.LENGTH_SHORT).show();

      }

What you are looking for is called Proximity Alerts. Proximity Alert gives you notification (triggers piece of code) when you come in or goes out from particular location range.
