I tried it on emulator and entered the latitude and longitude manually, and it worked fine. However, my problem

Answer 1

public class HomeActivity extends Activity implements LocationListener{
public static Context mContext;
private double latitude, longitude;
 public LocationManager mLocManager;

/**

                                    Toast.makeText(HomeActivity.this,

                        else if(arg1== LocationProvider.OUT_OF_SERVICE) { 
                                    Toast.makeText(HomeActivity.this, 
            "LocationProvider.OUT_OF_SERVICE", Toast.LENGTH_SHORT).show(); 
                        } 

}

}

This is the code i have use it for finding the device location with the help of latitude and longitude and we also call getLastLocationUpdate in this code. I hope this is very help full to you.
