Auto mounting external sd card

[Tom Johnson]

I'm trying to get my sdcard to automount on my nexus 10 through USB OTG cable.  I can manually mount it and it works. Here is what I have setup so far. Is there anything else I need to do? I manually mount it like "mount -t vfat /dev/block/sda1 /mnt/usbdisk"


init.manta.rc
    # usb usb sd card
    export SECONDARY_STORAGE /storage/usbdisk0
    mkdir /storage/usbdisk0 0666 system system

    symlink /storage/usbdisk0 /usbdisk
    symlink /storage/usbdisk0 /mnt/usbdisk


vold.fstab
dev_mount usbdisk /storage/usbdisk0 auto /dev/block/sda1

Dear Tom,

Have you updated storage_list.xml

[Tom]

Which one should I update? I see under device and under frameworks.

Update this one in device. In Android JB there is overlay directory which overwrites the content from frameworks/base

I have a question about the vold.fstab file . On the last parameter I need  sys filesystem path? If so, then I see lots of paths from udev events when I plug in usb SDCard. Which one do I use?

Dear Tom,

Under device, if storage_list.xml is in overlay directory, modify that only.

If not overlay directory then, modify the one in framework.

This file is bridge between vold and Android platform.
