Unable to resume activity : android.database.StaleDataException: Attempted to access a cursor after it has been closed. 异常

google的文档是这么写的
Warning: Do not call close() on a cursor obtained using this method, because the activity will do that for you at the appropriate time. However, if you call stopManagingCursor(Cursor) on a cursor from a managed query, the system will not automatically close the cursor and, in that case, you must call close().
也有人说用下面的方法可以避免这个问题
这个问题其实很简单 估计大家在查询数据库的时候用的是这个函数
viedoCursor = context.managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, videoColumns,null, null, null);
只要换成这样就可以了：
ContentResolver cr = context.getContentResolver();
viedoCursor = cr.query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, videoColumns,null, null, null);
我也是无意间发现有着两种写法的 然后试了一下问题就解决了
