You need to change

public void onAttach(Activity activity)

to

public void onAttach(Context context)

Final code:

@Override
public void onAttach(Context context) {
    super.onAttach(context);
    try {
       acitivtyCommander = (TopSectionListener) context;
    } catch (ClassCastException e){
        throw new ClassCastException(context.toString());
    }
}

ty for all your helping !! – omer malka Nov 14 '15 at 21:41
@MysticaL Why the app will crash if `super.onAttach(context);` is commented. How to decide whether call to super class lifecycle method(s) is required or not in case of fragments. In case of Activities, I know its a compulsion(else exception is thrown right) – AnV Oct 02 '16 at 12:52
