Returned location is null in TomTom Android SDK

问题

I'm trying to use TomTom's SDK for my Android app so I was practicing this tutorial https://developer.tomtom.com/maps-sdk-android/android-tutorials-use-cases/search-along-route but whenever I'm trying to invoke tomtomMap.centerOnMyLocation() I get an error. It used to work but now my returned location is always null.

Thanks in advance

Register map ready callback

mapFragment = (MapFragment) getSupportFragmentManager().findFragmentById(R.id.map_fragment);
mapFragment.getAsyncMap(onMapReadyCallback);

then enable location:

private OnMapReadyCallback onMapReadyCallback =
        new OnMapReadyCallback() {
   @Override
   public void onMapReady(TomtomMap map) {
      //Map is ready here
      tomtomMap = map;
      tomtomMap.setMyLocationEnabled(true);
   }
};

Forward permissions callbacks from Activity to TomtomMap to support runtime permission:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    tomtomMap.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
