Restore instance State Android

The challenge was to retrieve the data from SavedInstanceState, and set the textView as such. I'm pretty sure I did both, and it's compiling fine, but I keep getting this:

Bummer: There is no resource associated with id: 10. Note: setText(int) is not the same as setText(String).

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

public class MainActivity extends Activity {

  public TextView mTextView;
  public 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(savedInstanceState.getInt(KEY_USERENTRY));

    }
}
