android在使用SQLiteDatabase插入数据时，抛出如下异常：

W/CursorWindow(25503): Window is full: requested allocation 5583269 bytes, free space 2096639 bytes, window size 2097152 bytes

E/CursorWindow(25503): Failed to read row 0, column 1 from a CursorWindow which has 0 rows, 5 columns.
W/System.err(25503): java.lang.IllegalStateException: Couldn't read row 0, col 1 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it.
W/System.err(25503): at android.database.CursorWindow.nativeGetString(Native Method)
W/System.err(25503): at android.database.CursorWindow.getString(CursorWindow.java:442)
W/System.err(25503): at android.database.AbstractWindowedCursor.getString(AbstractWindowedCursor.java:51)

解决方法：数据库表字段值如果超过2M，那么就把值存在文件中，然后把文件路径存在此字段中。
