How to use it

To use simple inject a RoboDialogFragment and use it:

public class MyRoboFragment extends RoboFragment...

    @Inject
    private ProgressDialogFragment progressDialog;

    private void createProgressDialog(int resId) {
        Bundle arguments = new Bundle();
        arguments.putString(ProgressDialogFragment.MESSAGE, getString(resId));
        DialogFragmentHelper.show(getActivity(), progressDialog, arguments);
    } 
}
