When using fix-stack, it is looking for host's /data/app/org.mozilla.geckoview_example-1/lib/x86_64/libxul.so, not remote's. So it cannot resolve symbols like the following.

fix-stacks: error: failed to read `/data/app/org.mozilla.geckoview_example-1/lib/x86_64/libxul.so`
fix-stacks: No such file or directory (os error 2)

So I would like something options to use remote file (or using adb to get remote *.so) for resolving symbols.
