Code Challenge: Adding Data for the List error!!

Happy Holidays everyone! :)

So I'm going over the Android "Rebuilding from Scratch" lessons, and I ran into an error on the first task of this code challenge. I'm 99% sure this is correct but I figured I'd post my code here to see if anyone can point out if I'm doing something wrong, or there is an error in the compiling engine of treehouse for this challenge.

package com.example;

import android.app.ListActivity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter;

public class MainListActivity extends ListActivity {

public String[] mSongTitles = { "1", "2", "3" };

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_list);
}

}

(EDIT: This is the error I get "Bummer! Compilation Error! Make sure 'mSongTitles' is declared inside the curly braces of MainListActivity before the 'onCreate()' method.")
