Aviary SDK for Image Editing issue with setNavigationIcon of toolbar

Toolbar toolbar = (Toolbar) getView().findViewById((R.id.app_bar));
        ((BaseActivity) getActivity()).setSupportActionBar(toolbar);
        ((BaseActivity) getActivity()).getSupportActionBar().setDisplayShowTitleEnabled(false);
        toolbar.setNavigationIcon(R.drawable.ic_menu);

        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                ((MainActivity) getActivity()).openDrawer();

            }
        });

Here is my code segment. After adding Aviary SDK, image set on 'toolbar.setNavigationIcon(...)' not working & no icon is visible there. My drawer is sliding/working smoothly. I want to use this SDK & want the navigation icon too. How to do this?

Toolbar toolbar = (Toolbar) getView().findViewById((R.id.app_bar));
        toolbar.setNavigationIcon(R.drawable.ic_menu);
        ((BaseActivity) getActivity()).setSupportActionBar(toolbar);
        ((BaseActivity) getActivity()).getSupportActionBar().setDisplayShowTitleEnabled(false);
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                ((MainActivity) getActivity()).openDrawer();

            }
        });

Just changing the order solved my problem.
