------解决方案--------------------
这问题我今天刚遇到，不过在同事的指引下，解决了，4.0系统设置里有个开发者选项，将其关闭即可。

我使用了系统自带的图片裁剪程序（com.android.camera.action.CROP）进行裁剪，在2.X系统下一切正常，但是程序移到4.0后，竟然在裁剪完图片，保存并将图片数据返回上一个Activity是出错了！根据日志，错误不是发生在我程序里的，而是有一个不属于我程序的数据库游标被关闭了，这个搞得我一头雾水啊。以下是错误信息，请各位帮我看看是怎么回事：02-27 08:36:40.086: ERROR/AndroidRuntime(2496): FATAL EXCEPTION: main
