import android.util.Log;

public class GPSTracker extends Service implements LocationListener {

private final Context mContext;

// flag for GPS status
boolean isGPSEnabled = false;

// flag for network status
boolean isNetworkEnabled = false;

// flag for GPS status
boolean canGetLocation = false;

Location location; // location
double latitude; // latitude
double longitude; // longitude

// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters

// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute

// Declaring a Location Manager
protected LocationManager locationManager;

public GPSTracker(Context context) {
this.mContext = context;
getLocation();
}

public Location getLocation() {
 try {

 .isProviderEnabled(LocationManager.GPS_PROVIDER);

 // getting network status
 isNetworkEnabled = locationManager
 .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

 if (!isGPSEnabled && !isNetworkEnabled) {
 // no network provider is enabled
 } else {
 this.canGetLocation = true;
 if (isNetworkEnabled) {

   }
   }
   }
   }
  } catch (Exception e) {

This is MainClass.java



GPSTracker gps;
 
@Override
public void onCreate(Bundle savedInstanceState) {

 @Override
public void onClick(View arg0) {  
// create class object
gps = new GPSTracker(AndroidGPSTrackingActivity.this);

// check if GPS enabled  
if(gps.canGetLocation()){
           
       double latitude = gps.getLatitude();
        double longitude = gps.getLongitude();
           
   // \n is for new line
AlertDialog.Builder builder = new AlertDialog.Builder(AndroidGPSTrackingActivity.this);
        builder.setTitle("Your LOcation");
     builder.setMessage("Latitude :"+ latitude+ "\nLongitude :"+ longitude);  
        AlertDialog alert = builder.create();
        alert.show(); 
         
        }else{
        // can't get location
       // GPS or Network is not enabled
        // Ask user to enable GPS/network in settings
        gps.showSettingsAlert();
