Linha de arquivos XML binários nº 8: Erro ao inflar o fragmento de classe, o Google Maps

Neste aplicativo, estou tentando adicionar um mapa do google V2 funcional. Eu olhei para a maioria dos tutoriais para criar uma atividade, obtendo uma chave para os mapas e criando o arquivo xml para tentar ver se eu perdi qualquer passo (eu passei por eles como 4 vezes), e isso não acontece Parece que perdi qualquer passo.

Aqui é o site que usei:

Quando executo meu aplicativo no meu telefone (já que o Google Play Services não funciona no emulador), isso me causa dois erros:

  02-11 22:10:54.690: E/AndroidRuntime(4526): java.lang.RuntimeException: Unable to       start activity ComponentInfo{com.example.myfirstapp/com.example.myfirstapp.ShowActivity}:       android.view.InflateException: Binary XML file line #8: Error inflating class fragment
  02-11 22:10:54.690: E/AndroidRuntime(4526): 

  Caused by: android.app.Fragment$InstantiationException: Unable to instantiate fragment       com.google.android.gms.maps.MapFragment: make sure class name exists, is public, and has an empty constructor that is public

Aqui está a minha atividade:

package com.example.myfirstapp;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import com.google.android.maps.*;
import com.google.android.gms.maps.MapFragment;
public class ShowActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_map, menu);
    return true;
}

//@Override
//protected boolean isRouteDisplayed() {
    // TODO Auto-generated method stub
    //return false;
//}

    }

Desculpe pela formatação, mas aqui está o meu arquivo xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".ShowActivity" >

<fragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />

  </RelativeLayout>

Eu importei a API do Google e os serviços do Google Play para que todas as importações estejam funcionando, o que me faz pensar por que o segundo erro dizia que o MapFragment estava vazio. Código do arquivo de manifesto:
