The saved value in the bundle is integer. How to display it in text view. Integer.toString?

There are at least 2 ways to display integer in text view. But my code is not accepted as an correct answer. Did I miss something in the question?

MainActivity.java 
import android.content.Intent;
import android.view.View;

public class MainActivity extends Activity {

  public TextView mTextView;
  private static final String KEY_USERENTRY = "KEY_USERENTRY";
  //private static final String NEW_KEY = "nk";
  private int user_entry;
  //private String tmp = "TMP";



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

    mTextView = (TextView) findViewById(R.id.textView);
    mTextView.setText(Integer.toString(user_entry));The saved value in the bundle is integer. 
    //mTextView.setText(tmp);
  }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putInt(KEY_USERENTRY, 10);
        //outState.putString(NEW_KEY, tmp);

    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
        user_entry = savedInstanceState.getInt(KEY_USERENTRY);
        //tmp = savedInstanceState.getString(NEW_KEY);

    }
}
