You are interested in /system/etc/vold.fstab.
您对/system/etc/vold.fstab.
- Backup your system.
- Install Root Explorer (I use ES File Explorer).
- Mount system with write privileges (ES File Explorer has it in Settings).
- Backup
/system/etc/vold.fstabto sdcard and to your PC. - Open
/system/etc/vold.fstabwith Text Editor. Here you can find mount points in 3rd column:
dev_mount sdcard /mnt/sdcard
Read something about fstaband comments in file. Be careful. ;o)
- 备份您的系统。
- 安装根资源管理器（我使用 ES 文件资源管理器）。
- 使用写入权限挂载系统（ES 文件资源管理器在“设置”中有它）。
- 备份
/system/etc/vold.fstab到 SD 卡和您的 PC。 /system/etc/vold.fstab用文本编辑器打开。在这里，您可以在第 3 列中找到挂载点：
dev_mount sdcard /mnt/sdcard
阅读有关 fstab和文件中的注释的内容。当心。;o)

You cannot change a device's file structure. You can ask Android where the SD card is with Environment.getExternalStorageDirectory(). This approach works whether a manufacturer specifies the sdcard is in /sdcard/, /mnt/sdcard/, or /way/out/in/the/willy/wacks/sdcard/.
您无法更改设备的文件结构。您可以使用Environment.getExternalStorageDirectory()询问 Android 的 SD 卡在哪里。无论制造商是否指定 sdcard 是在、 或中/sdcard/，此方法都有效。/mnt/sdcard//way/out/in/the/willy/wacks/sdcard/
You should also observe the Android protocol for saving sdcard data in .../sdcard/Android/data/your.package.name/with Environment.getExternalStoragePublicDirectory()or just Context.getExternalFilesDir().
您还应该遵守 Android 协议，用于.../sdcard/Android/data/your.package.name/使用Environment.getExternalStoragePublicDirectory()或仅Context.getExternalFilesDir()保存 sdcard 数据。
