Call onSaveInstanceState without calling super.onSaveInstanceState(outState)

Question

If I will use this code without calling super.onSaveInstanceState(outState);

@Override protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putLong(ID, mId);
}

like this:

@Override protected void onSaveInstanceState(Bundle outState) {      
        outState.putLong(ID, mId);
    }

What problems can be?

Answer 1

The activity itself saves some of the values in the bundle e.g state of the Fragments, if you do not call the super method, those values will not be saved.
