move application = (LaftelApplication) getActivity().getApplication(); from onCreateView to onActivityCreated

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    application = (LaftelApplication) getActivity().getApplication();
}
