在Android上获取绝对路径 [英] Getting absolute path on android

问题描述

我有c ++代码，其中尝试从android设备上的目录中获取文件.我尝试了不同的方法来设置传递给fopen()函数的路径，例如: /Android/data/com.myapp/files/Blip.wav 实际上有这个文件.但是我想这不是编写路径的正确方法. (该示例是通过Java代码获得的)

I've got c++ code in which I try to get a file from a directory on an android device. I've tried different ways to set the path which I pass to the fopen() function like: /Android/data/com.myapp/files/Blip.wav There actually is this file. But I guess that this is not a proper way to write a path. (The example was obtained by the java code )

getContext().getApplicationContext().getFilesDir().getPath() + "/Blip.wav"

推荐答案

实际上有这个文件

There actually is this file

由于我从未见过具有/Android目录的Android设备，因此不太可能.

Since I have never seen an Android device with an /Android directory, that is unlikely.

如果您正在使用USB或类似连接在台式机文件管理器中查看/Android/data/com.myapp/files/Blip.wav，那么将适合什么.在这种情况下，Android/data/com.myapp/files/Blip.wav是外部存储中的相对路径.具体来说，它映射到:

What would fit is if you are looking at /Android/data/com.myapp/files/Blip.wav in a desktop file manager, using a USB or similar connection. In that case, Android/data/com.myapp/files/Blip.wav is a relative path in external storage. Specifically, it maps to:

new File(getContext().getExternalFilesDir(), "Blip.wav")
