如何列出其他外部存储文件夹（安装点）？(How to list additional external storage folders (mount points)?)

默认情况下，Android上的“外部”存储显示为/ sdcard文件夹。 在某些设备上，它不是SD卡，而是内存。

某些设备允许附加额外的SD卡，或者在华硕变压器的情况下，还可以附加2个USB闪存盘。

这种增加的内存驱动器显示为某个文件夹，该位置取决于设备制造商。 在某些设备上，它位于/ sdcard文件夹内，其他设备位于其他文件夹中的其他位置。

现在我的问题是，如果有一些功能列出除标准/ SD卡文件夹之外的所有可能的外部存储。

By default, "external" storage on Android is presented as /sdcard folder. On some devices it's not SD card but internal memory.

Some devices allow attachment of additional SD card, or in case of Asus Transformer, also additional 2 USB flash discs.

Such added memory drive appears as some folder, which location depends on device manufacturer. On some devices it's inside /sdcard folder, on others it's elsewhere in other folder.

Now my question is, if there's some function to list all possible external storages besides standard /sdcard folder.

您可以阅读/proc/mounts来查找当前安装的内容。

或者你可以阅读/etc/vold.conf或/etc/vold.fstab （它取决于配置文件的版本）。 该文件包含可移动存储的配置。 平板电脑默认存储通常不存在于vold中。

You can read /proc/mounts to find out what is currently mounted.

Or you can read /etc/vold.conf or /etc/vold.fstab (it depends on version what config file is present). This files contains config for removable storages. At tablet default storage is not usually present in vold.
