Question

我正在尝试从外部SD读取一些文件。

final File externalStorage =  Environment.getExternalStorageDirectory();

String list = "";//
list+= "Listing all the files in SD: "  + externalStorage.getAbsolutePath() + "\n";
Log.i("VVV", list);

for (File file: externalStorage.listFiles()) {
    Log.i("VVV", file.getAbsolutePath());
    list += file.getAbsolutePath() + "\n";
}

我正在尝试阅读我的外部SD。我不知道为什么总是得到/ emulate / 0路径而不是/ storage / sdcard。

它是上述代码的输出：

所以我不知道我做错了什么？

External storage不是removable storage。您的代码正在访问外部存储。您没有文件系统访问可移动存储上的任意位置。欢迎您使用the Storage Access Framework要求用户打开文档，用户可以选择可移动存储上的文档。
