android - 谷歌地图 V2 崩溃

Question

一切正常，直到我更新我的 android 工具版本 22.3、android sdk 平台工具版本 19.0.1、android 支持库版本 19.0.1、google play 服务版本 15。

现在，每当我使用谷歌地图访问我的 Activity 时，我的应用程序就会崩溃。登录目录:

OnCreate 谷歌地图 Activity :

SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

            googleMap = fm.getMap();

            googleMap.setMyLocationEnabled(true);

            googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);  

在我更新我在 Android SDK 管理器中上面所说的内容之前，它工作正常。我应该怎么办？请帮忙。我应该重新安装我的 eclipse adt 吗？
