Right... how exactly are you trying to access /sdcard?  Through Dired?
If so, my guess is that ls-lisp is trying to stat the root file system,
which is forbidden by some versions of Android.  Would you please enable
debug-on-error (Options -> Enter Debugger on Error) and display the
backtrace from whatever file access operation complains?

Thanks.
