outState.putString

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

Error doesn't make sense to me.

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.putString(KEY_USERENTRY, "10");

    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);

    }
}

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

outState.putInt(KEY_USERENTRY, 10);
