您好，这是一个兼容性错误，位于：

E/AndroidRuntime（6549）：由：java.lang.ClassNotFoundException:android.view.fragment在加载程序dalvik.system.PathClassLoader[/data/app/com.gaditek.ihistro-1.apk]中引起
您正试图在代码中使用Fragment
，但要使Fragment在姜饼和姜饼下工作，您必须从Google导入一个兼容性库：在这里查找和此
因此，请确保将您的活动
转换为FragmentActivity
，并使用getSupportFragmentManager（）
而不是getFragmentManager（）

我才发现问题就在这里
map=（（MapFragment）getFragmentManager（）.findFragmentById（R.id.map））.getMap（）
应该是
map=（（SupportMapFragment）getSupportFragmentManager（）.findFragmentById（R.id.map））.getMap（）
正如@Glenn所述，活动需要通过碎片活动而不是活动进行扩展
.. 因此解决了

我面临的启动活动问题。。i-e PerxDetailedActivity包含map v2库的另一个片段是的，这是正常的，但错误并不总是位于第一行。你必须添加，以使你的应用程序在姜饼上工作。是的，整个应用程序使用的是片段，除了这一部分，工作正常。。。。当我需要打开一个新的活动时，用编辑过的代码（和导入）更新你的帖子。确保将所有活动
转化为碎片活动
