Problem with the OnRestoreState Method

Can someone please help me find a solution to the code for setting the text and TextView and equalling it tp the value of the bundle.

Thank you

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";


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

    mTextView = (TextView) findViewById(R.id.textView);
  }

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

    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
      mTextView.setText(String.KEY_USERENTRY);




    }
}

Try mTextView.setText(savedInstanceState.getInt(KEY_USERENTRY)+""); instead of mTextView.setText(String.KEY_USERENTRY);

Thanks Hwl,

This was the code cracker: mTextView.setText(savedInstanceState.getInt(KEY_USERENTRY) + "");
