如何在Android应用程序中编辑资源文件?(Android Studio) [英] How to edit a resource file from within an android app? (Android Studio)

问题描述

我正在创建一个利用日志的android应用.我已经在原始"资源文件夹中放置了一个名为"log.txt"的文件.我已经弄清楚了如何使用 openRawResource 将其打开到输入流，但是我不确定如何打开它，因此可以将它与 PrintWriter 一起使用.

I'm creating an android app that utilizes a log. I've placed a file entitled "log.txt" in the "Raw" resource folder. I have figured out how to open it to an inputstream using openRawResource, however I am not sure how to open it so I can use PrintWriter with it.

我还尝试访问在目标设备上预先创建的文件，但没有成功.

I have also tried accessing a file pre-created on the target device, but have not succeeded.

如果有人可以向我解释如何将资源文件打开到PrintWriter，我将不胜感激.
