我有一个正在处理的项目但是当我尝试启动包含地图的活动时出现此错误。
以下是我从logCat获得的内容：

我已从项目中的libs文件夹中删除了android-support-v4.jar，但我看到该文件位于我使用的库中。谁能告诉我怎么解决这个问题？

答案 0 :(得分：0)
您扩展FragmentActivity并拥有
map = ((MapFragment) getFragmentManager()
.findFragmentById(R.id.map)).getMap();
您应该使用SupportMapFragment。 FragmentActivity是基于支持的Fragments的基类。
map = ((SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();
您还需要导入com.google.android.gms.maps.SupportMapFragment。
确保您在xml中也有SupportMapFragment
答案 1 :(得分：0)
尝试以下代码： -
GoogleMap map;
SupportMapFragment mapFragment;
android.support.v4.app.FragmentManager fragmentManager;
fragmentManager = this.getSupportFragmentManager();// use getActivity() instead of this when you work on fragment only
mapFragment = (SupportMapFragment) fragmentManager.findFragmentById(R.id.map);
map = mapFragment.getMap();
