无法将项目从Google maps api v1转换为v2

Question

我从这里获取Google maps api v1项目：http://www.androidhive.info/2012/01/android-working-with-google-maps/

然后我想将其转换为Google maps api v2。

的AndroidManifest.xml：

我在我的Android设备上运行，三星S2与Android 4.0.3

控制台：

之后，它说“不幸的是GoogleMaps停止了。”

3天我努力解决这个问题，但没有解决。请帮帮我

Answer 1

没有简单的方法从v1移植到v2。

最好的办法是删除与地图相关的所有代码，并按照地图v2的官方文档或找到自己的v2教程。

Answer 2

无需使用public class AddItemizedOverlay extends ItemizedOverlay<OverlayItem>

添加标记，请参阅粗体文字。

public class MapActivity extends Activity implements OnMarkerDragListener

    private GoogleMap map;

    SharedPreferences mapPref;
    List<Address> addresses;
    MarkerOptions mark;
    String address,city,country,admin,subAdmin,location;

    public void onCreate(Bundle savedInstanceState){
