"Remember to declare field as final" error even though I wrote final

Im not exactly sure what the error is here. This was a question from the IntroducingSharedPreferences challenge

MainActivity.java
import android.view.View;
import android.os.Bundle;

public class MainActivity extends Activity {

  public CheckBox mCheckBox;
  public static final String PREFS_FILE;
  public static final String KEY_CHECHBOX;


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

    mCheckBox = (CheckBox) findViewById(R.id.checkBox);
  }
}

public static final String PREFS_FILE = "";
public static final String KEY_CHECKBOX = "";

Just a simple spelling error, checkbox was spelled wrong.
