Finish activity before it starts?

I have registered my activity to handle the ACTION_DIAL intent but in certain cases I want to basically ignore the intent. In onCreate, I'm checking SharedPreferences for a bool that means user has access to dial, if not then I call finish() and then return; But this still shows a window flashing open and then closed, how can I avoid that?

protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
    boolean hasDialer = prefs.getBoolean(Preferences.HAS_DIALER, false);

    // Check if ACTION_DIAL intent was launched to bring user into the app
    String number = getIntent().getDataString();
    if (!TextUtils.isEmpty(number))
    {
        if (hasDialer)
        {
            launchDialer = true;
        }
        else
        {
            finish();
            return;
        }
    }
}

You could register the ACTION_DIAL in a broadcast receiver (directly in the manifest) or in a service (now this depends on what else are you planning to do) and have the same logic in there. You can start activities from there if you need to.
