本文针对Android 7.1

 

/sdcard是/mnt/sdcard的符号链,指向/storage/self/primary,

/mnt/sdcard,也是符号链,指向/storage/self/primary,

/storage/10F5-111D 是sdcard的分区……

一些路径的解释:

  • /storage/emulated/0/: to my knowledge, this refers to the "emulated MMC" ("owner part"). Usually this is the internal one. The "0" stands for the user here, "0" is the first user aka device-owner. If you create additional users, this number will increment for each.
  • /storage/emulated/legacy/ as before, but pointing to the part of the currently working user (for the owner, this would be a symlink to /storage/emulated/0/). So this path should bring every user to his "part".
  • /sdcard/: According to a comment by Shywim, this is a symlink to...
    • /mnt/sdcard (Android < 4.0)
    • /storage/sdcard0 (Android 4.0+)
  • /storage/sdcard0/: As there‘s no legacy pendant here (see comments below), the "0" in this case rather identifies the device (card) itself. One could, eventually, connect a card reader with another SDCard via OTG, which then would become /storage/sdcard1 (no proof for that, just a guess -- but I‘d say a good one)
