ScreenManager extends FadingGame {
public ScreenManager() {

Same problem here. Main class looks like this:

public class Template extends FadingGame {

    public ActionResolver actionResolver;

    public Template(ActionResolver actionResolver) {
        super(new SpriteBatch());
        this.actionResolver = actionResolver;
    }

    @Override
    public void create () {
    ...
    }

Not sure if the actual version of libgdx changed some things and if the lib is still working for that version.
Sorry, but i don´t have the time to look after that, if you find the problem it would be great if you submit a pull request. Thanks.
