I lost all my source code due to an error. I had already loaded the apk of a version of my app on my Glass. How can I get the apk of my app off my Glass so I can decompile it?

I tried the command below:

./adb pull /data/app/myapp.apk

But it didn't work. Any other approaches?

You have to have the Glass rooted in order to retrieve the APK's you already installed (just like on your phone), however you are in a catch 22 I believe because if I remember correctly in rooting it you'll be doing a factory reset.
