.getExtras()' on a null object reference

Question

I am trying to pass a few values between my activities to make a game work. However, the new activity after passing the information always returns null when I try to .getExtras(

Answer 1

Move

Bundle extras = getIntent().getExtras();

ArrayList players = extras.getIntegerArrayList("players");
int currentPlayer = extras.getInt("newPlayerNum");

into onCreate(). getIntent() needs a Context which isn't available before onCreate()

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_three_sign_game);

    // here
     Bundle extras = getIntent().getExtras();

     ArrayList players = extras.getIntegerArrayList("players");
     int currentPlayer = extras.getInt("newPlayerNum");
}
