Have latitude and longitude in a service return 0.0

I am a beginner in Android application development. I will get latitude and longitude from GPSTracker.class every 5 minutes for send to SQLite DB in next step but when I call GPSTracker.class
It's return latitude = 0.0 and longitude = 0.0 too
help me please
This is my code

The fused location provider is a location API in Google Play services that intelligently combines different signals to provide the location information that your app needs.
The fused location provider manages the underlying location technologies, such as GPS and Wi-Fi, and provides a simple API that you can use to specify the required quality of service. For example, you can request the most accurate data available, or the best accuracy possible with no additional power consumption.
Last Known Location
Receiving Location Updates

This code
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("GPS Enabled", "GPS Enabled");
if (locationManager != null) {
locations = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (locations != null) {
latitude = locations.getLatitude();
longitude = locations.getLongitude();
}
}
needs to be refactored. When you call LocationManager.requestUpdates() you are asking the LocationManager to call your app back when there is an update to the GPS position. This will happen at some later time (in the future), depending on how long it takes for the phone to determine its position using GPS. The call to LocationManager.getLastKnownLocation() will only return the last "known" location, which it doesn't have yet.
Once you have requested location updates, Your app will be called back with GPS data. The framework will call the method onLocationChanged(). You currently have no code in that method, so you won't do anything when the method is called.

Android GPS_PROVIDER always returns null

I'm developing an app and when I try to get the location of Android, I always get null.
I try this with a real device, running API 19 and with the GPS enabled
This is my code:
double latitud, longitud;
Location location;
LocationManager mlocManager;
LocationListener locationListener;
String provider;
final boolean gpsEnabled = mlocManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
if (!gpsEnabled) {
Intent settingsIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(settingsIntent);
}
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION,}, 1000);
return;
}
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
provider = mlocManager.getBestProvider(criteria, true);
Log.i("PROVIDER", provider);
locationListener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
latitud = location.getLatitude();
longitud = location.getLongitude();
}
#Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
#Override
public void onProviderEnabled(String s) {
}
#Override
public void onProviderDisabled(String s) {
}
};
mlocManager.requestLocationUpdates(provider, 0, 0,locationListener);
location = mlocManager.getLastKnownLocation(provider);
if (location != null) {
latitud = location.getLatitude();
longitud = location.getLongitude();
Log.i("LATITUD GPS", String.valueOf(latitud));
Log.i("LONGITUD GPS", String.valueOf(longitud));
} else {
Log.e("LOCATION", "null");
}
}
I tried to use LocationManager.GPS_PROVIDER instead of Criteria, but it doesn't work.
Thanks in advance.

Lat/lgn return 0

I'm currently working on a project for school. I have to use location service. I have a marker problem. I can locate myself on the map with a small point from google (I think), but the marker is always on 0,0. If my logic is good, the getLatitude() and the getLongitude() return NULL. I've follow a tutorial for the code.
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
GPSTracker gps;
//ImageItem imgItem;
double lat;
double longi;
double latitude;

String adresse;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
laCreation();
}
public void laCreation() {
gps = new GPSTracker(MapsActivity.this);
if (gps.canGetLocation()==true) {
latitude = gps.getLatitude();
longitude = gps.getLongitude();
lat = latitude;
longi = longitude;
} else {
gps.showSettingsAlert();
}
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
mMap = mapFragment.getMap();
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}
mMap.setMyLocationEnabled(true);
LatLng position = new LatLng(lat, longi);
mMap.addMarker(new MarkerOptions().position(position).title("Vous : "+ latitude + ","+longitude +"," +adresse));//new LatLng(lat,longi)
mMap.moveCamera(CameraUpdateFactory.newLatLng(position));

I'm French, sorry for my bad English

You should utilize method
#Override
public void onLocationChanged(Location location) {
Log.i(TAG, location.getLatitude()+"-"+longitude = location.getLongitude());
// TODO Auto-generated method stub
}
for getting latitude and longitude. First time it will get definitely call and then it will be call and then as soon as location gets changed.
If you force fully asking for latti and longi their are chances OS is not having anything s it would return 0,0.
One way more ask for last known location using GoogleFuseLocationApi

private static final String TAG = SpotRecognistionService.class.getSimpleName();

Location Menager - Location Updates

So I'm trying to update the current location of a user every 5 seconds using a locationMenager, but it's not working. Here the code:
GPSTracker.java
public class GPSTracker extends Service implements LocationListener {
private final Context context;
boolean isGPSEnabled = false;
boolean isNetworkEnabled = false;
boolean canGetLocation = false;

private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10;
private static final long MIN_TIME_BW_UPDATES = 5000;
protected LocationManager locationManager;
public GPSTracker(Context context) {
this.context = context;
getLocation();
}
public Location getLocation() {
try {
locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);
isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if(!isGPSEnabled && !isNetworkEnabled) {
} else {
this.canGetLocation = true;
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}

}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return location;
}
public void stopUsingGPS() {
if(locationManager != null) {
locationManager.removeUpdates(GPSTracker.this);
}
}

if(location != null) {
latitude = location.getLatitude();
}
return latitude;
}
public double getLongitude() {
if(location != null) {
longitude = location.getLongitude();
}
return longitude;
}
public boolean canGetLocation() {
return this.canGetLocation;
}
public void showSettingsAlert() {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(context);
alertDialog.setTitle("GPS is settings");
alertDialog.setMessage("GPS is not enabled. Do you want to go to settings menu?");
alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {

}
});
alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

alertDialog.show();
}

As you can see it is set to update. And this is the onCreate() in SearchActivity.java
gps = new GPSTracker(SearchActivity.this);
if (gps.canGetLocation()) {
ParseUser user2 = ParseUser.getCurrentUser();
double latitude = gps.getLatitude();
double longitude = gps.getLongitude();
geoPoint = new ParseGeoPoint(latitude, longitude);
user2.put("lat_long", geoPoint);
textView.setText(latitude+" "+longitude);
user2.saveInBackground();
} else {
gps.showSettingsAlert();
}
So if I put the code above in a onClick method it works, it updates the current location. I've tried to implement it with a TimerTask but the location ends up being (0, 0). So does anyone know what I can do here? Because what preferably I would like to make a On/Off switch for the location, make it run in background if possible, but first I would like to resolve the issue with the Location Updates.

#Override
public void onLocationChanged(Location location) {
this.location = location;
getLatitude();
getLongitude();
ParseUser user2 = ParseUser.getCurrentUser();
ParseGeoPoint geoPoint = new ParseGeoPoint(getLatitude(), getLongitude());
user2.put("lat_long", geoPoint);
user2.saveInBackground();
}
Okay so this was the answer, just had to change the onLocationChanged.
