public class MainActivity extends ActionBarActivity { 
GoogleMap map=null; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     if(map==null) 
     { 
     map=((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); 
     } 
    } 

}

Какая часть

Требуемый тег мета-данных в AndroidManifest.xml вашего приложения не существует. Вы должны иметь следующее заявление в элемент < приложения>: < мета-данных андроид: имя = "com.google.android.gms.version" Android: значение = "@ целое число/google_play_services_version" />

вы не понимаете? Вы только объявили ключ API, вы также должны добавить версию Служебных услуг.
