Now I’m at /storage/2FC9-191C and able to list the contents because my terminal app has “media” access in Android.Next I change over to my SD card that has the volume label “2FC9-191C” ( cd 2FC9-191C).I try to list the contents of /storage and I’m denied.I change over to the base storage directory ( cd /storage).In the screenshot above (cropped for size), the shell prompt in the terminal app starts at the root of Android’s filesystem ( /): Here’s a real-world demonstration on my phone using a terminal app: It would be tedious to set it up for all the folders I wanted to sync, but it would be an acceptable workaround. Or am I completely missing something and getting insane? But let’s not get too hung up on the “entire root” part, if it worked for folders I created on the SD card root, I wouldn’t be complaining. stfolder on the root of the SD card, it has to have write access to the root. However, it doesn’t mean that Syncthing can now simply come along and copy files into the Music folder above because the folder was created by VLC. Likewise, Syncthing could also be told to use the root of the SD card, and if granted access by the user: storage/1234-ABCD/.stfolder So VLC could make a subdirectory: storage/1234-ABCD/Music It doesn’t matter what permissions are on the subdirectory 1234-ABCD because it’ll be superseded by whatever is applied during the automount.Īndroid allows an app to create files and folders at the root of the SD card if the app has been granted permissions by user. The path above is then the mount point for the SD card. When the SD card is inserted, Android 10 and up creates a temporary subdirectory under /storage using the SD card’s label: storage/1234-ABCD Take the following example where the volume label for a SD card is “1234-ABCD”. So ifĪh… but the key is that the root of the SD card isn’t a regular directory. But at least in my mind you shouldn’t be able to create a folder if you don’t have write access to the directory you are creating it in. rwxr-r- system system 8 09:55 hidden_volume.Yes, that’s because it’s Android 10 (or higher) – and the. rw-rw-rw- nobody nobody 95613 09:45 cops.logĭrwxrwx-x system system 09:45 dalvik-cache rw- system system 2777 09:55 cal.binĭrwxrwxr-x system system 07:37 clipboard rw-rw-rw- root system 0 06:31 adm.sqlite-copy-datestamp-JBĭrwxrwx-x system system 12:26 app-private Ui_print("SuperSU 0.95 & Busybox 1.20.2") Īfter reading and playing around with adb I decided that I go for itįor strengthening my decision a checked if the MD5 matches and it md5 root.zip Run_program("/tmp/busybox", "umount", "/system") Run_program("/system/xbin/busybox", "-install", "-s", "/system/xbin") Package_extract_dir("system", "/system") Ui_print("Installing Superuser & Busybox.")
