Question

我是Android上的新手，我试图将谷歌地图与我的应用程序集成，我也尝试了vogella和androidhive，并看到堆栈上的问题和答案溢出但这里没有任何作品是android代码

    private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; //10 metters

    //The minimum time beetwen updates in milliseconds
    private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute
    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.mainscreen);
    // .findFragmentById(R.id.map))
    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

        if (map!=null){
          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)));
        }

}

这是xml代码

<fragment 
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />

在这里我有例外，请告诉我我错在哪里
