Android Android Activity Lifecycle The Activity Lifecycle Saving and Retrieving Instance State

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);

    }
}
