openFileOutput FileNotFoundException异常 [英] openFileOutput FileNotFoundException

问题描述

这是我的一周noob问题。我在寻找更一般的炒作不是具体的code，也许希望Android的人正在看，并可能纠正此：

This is my noob question for the week. I'm looking more for general speculation than specific code and maybe hoping the Android folks are watching and could correct this:

SDK文档Context.openFileOutput说：

the SDK documentation for Context.openFileOutput says:

打开这个背景下的应用程序包写入相关的私人文件。创建该文件，如果它不存在。

Open a private file associated with this Context's application package for writing. Creates the file if it doesn't already exist.

好吧，这听起来不错。我可以创建一个文件。除了这种方法也抛出FileNotFoundException异常，那么显然有什么不妥。为什么一个功能是的应该的到，如果没有找到抛出一个异常创建一个文件，如果没有找到???文件

Ok, that sounds good. I can create a file. Except this method also throws a FileNotFoundException, so apparently something is amiss. Why would a function that is supposed to create a file if it's not found throw an exception if the file is not found???

有点儿违背了整个创建文件...的事情，不是吗？

Kinda defeats that whole "Creates the file..." thing, doesn't it?

推荐答案

我要道歉，跳跃之前，我看了就这一个。我有点慌了，而阅读文档。经过一些测试，我发现 openFileOutput（）呢，其实，工作通告和将的创建一个文件，如果没有找到，而不仅仅是抛出FNF例外，因为我害怕。显然，FNF掷中加入的情况下的活动的应用程序的目录不存在

I have to apologize for leaping before I looked on this one. I kinda panicked while reading the documentation. After some testing, I found that openFileOutput() does, in fact, work as advertised and will create a file if it's not found, not just throw an FnF exception as I feared. Apparently, the FnF throw was added in case the Activity's application directory does not exist.

此外，我的道歉，但希望，这可能帮助别人谁是文档相混淆。

Again, my apologies but hopefully, this might help others who are confused by the documentation.
