Not sure what I'm doing wrong. Task is to save the number 10 to the bundle.

Error doesn't make sense to me.

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

public class MainActivity extends Activity {

  public TextView mTextView;
  private static final String KEY_USERENTRY = "KEY_USERENTRY";

  protected void onCreate(Bundle savedInstanceState) {

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

    protected void onSaveInstanceState(Bundle outState) {
      outState.putString(KEY_USERENTRY, "10");


    protected void onRestoreInstanceState(Bundle savedInstanceState) {

Since it says "save the number 10 to the bundle" use putInt() instead:

outState.putInt(KEY_USERENTRY, 10);
