Get User location and show it on map(map that isn't appearing for me)

I'm doing a university project, and i've to show user location in the OSM map, and markers with data from Retrofit API.
I'm not worried about api data right now, but with my map that isn't showing.
All i got is this:MainMap
The coordinates here are random.
My map activity:
public class MapaPrincipal extends AppCompatActivity implements LocationListener {
private MapView osm;
private MapController mc;
private LocationManager locationManager;
#RequiresApi(api = Build.VERSION_CODES.M)
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mapa_principal);
osm = (MapView) findViewById(R.id.mapView);
osm.setTileSource(TileSourceFactory.MAPNIK);
osm.setBuiltInZoomControls(true);
osm.setMultiTouchControls(true);
mc = (MapController) osm.getController();
GeoPoint center = new GeoPoint(14.1, 19.2);
mc.setZoom(12);
mc.animateTo(center);
addMarker(center);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// Activity#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for Activity#requestPermissions for more details.
return;
}
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
public void addMarker(GeoPoint center){
Marker marker = new Marker(osm);
marker.setPosition(center);
marker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_BOTTOM);
osm.getOverlays().clear();
osm.getOverlays().add(marker);
osm.invalidate();
}
#Override
public void onLocationChanged(Location location) {
GeoPoint center = new GeoPoint(location.getLatitude(),location.getLongitude());
mc.animateTo(center);
addMarker(center);
}
#Override

#Override
public void onProviderDisabled(String s) {
}
#Override
protected void onDestroy() {
super.onDestroy();
if(locationManager!=null){
locationManager.removeUpdates(this);
}
}

Your code works perfect. You just have to move your device in the place where gps is available, because the place where you are testing your app may not have exposure to GPS satellite.
onLocationChanged() will be called once GPS is detected by the device

Check your project from there

But i think problem with manifest
