Is crime argument on onCrimUpdated(Crime crime) necessary?

[antoniorosario]

When mCallbacks.onCrimeUpdated(); is called in CrimeFragment and then called by CrimeListActivity the argument crime doesn’t get used in the following method body:
public void onCrimeUpdated(Crime crime) { CrimeListFragment listFragment = (CrimeListFragment) getSupportFragmentManager() .findFragmentById(R.id.fragment_container); listFragment.updateUI(); }

I removed the Crime crime argument from the code and reran the app both on a phone and a tablet and nothing seemed to change. Is it necessary to pass crime as an argument into onCrimeUpdated?

I agree with you.
The code is running well without this “crime” parameter.
