Re: adb umount problems

I found something in the output of the adb shell that caught my eye.

root@android:/ # ls -l /mnt/sdcard
lrwxrwxrwx root root 2012-11-30 12:59 sdcard -> /storage/sdcard1


The last item, "sdcard1" is how both file managers on the device now label the sdcard. What does "sdcard -> /storage/sdcard1" mean?

The "sdcard -> /storage/sdcard1" means that "sdcard" is a symbolic link to
/storage/sdcard1" The letter "L" at the beginnng of the permissions confirms that.

Try "fuser /storage/sdcard1" and see what it yields. (Hopefully one or more process id numbers.)

Apparently this is all related to Google changing the way it deals with usb connection. With the new Android 4.+ (Jellybean) they've gone to MTP which is why I couldn't see the device from nautilus in Ubuntu. When I ran a ROM based on Android 2.7 (Gingerbread) my Ubuntu nautilus could view it.

The third sentence in the above link refers to a very good explanation with a comment from a google engineer as to why the switch.

That is a very good read, and explains a lot of the confusion I had been having about why I could not switch off of MTP.
