Ошибка раздувания проблем фрагмента класса в xml

Question

Я хочу добавить карту в фрагмент (err, FragmentActivity?). Файлы java не дают никаких ошибок, но скорее всего в строке XML-файла 65 появляется ошибка времени выполнения.

вот мой код и ошибка (в прилагаемом XML, xml). ....

static final LatLng HAMBURG = new LatLng(53.558, 9.927); 
    static final LatLng KIEL = new LatLng(53.551, 9.993); 
    private GoogleMap map; 

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 

    View v = inflater.inflate(R.layout.activity_map_, null, false); 

    map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.fragment2)).getMap(); 

Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG) 
      .title("Hamburg")); 
     Marker kiel = map.addMarker(new MarkerOptions() 
      .position(KIEL) 
      .title("Kiel") 
      .snippet("Kiel is cool") 
      .icon(BitmapDescriptorFactory 
       .fromResource(R.drawable.ic_launcher))); 

     map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15)); 

     // Zoom in, animating the camera. 
     map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null); 
    return v; 
} ... 

Там нет ошибки есть.

И XML линия вопрос:

   <LinearLayout 
        android:id="@+id/tab2" 
        android:layout_width="match_parent" 
        android:layout_height="match_parent" 
        android:orientation="vertical" > 
      65  <fragment THIS IS THE LINE. 
         android:id="@+id/fragment2" 
         android:name="com.example.soconnection.MapActivity2" 
         android:layout_width="match_parent" 
         android:layout_height="wrap_content" 
         class ="com.google.android.gms.maps.SupportsMapFragment"/> 
      </LinearLayout> 

Как мне это исправить. Если я не упустил что-то, то я уже все изменил, чтобы получитьSUpportFragment и т. Д.

java.lang.ClassNotFoundException: Didn't find class "com.google.android.gms.maps.SupportsMapFragment" 

Вы используете Android Studio? Возможно, вам придется выполнить полную перестройку. Build -> Rebuild Project
