Hi, my name is robert. I am kinda new to the entire game programming thing. I recently found a tutorial on how to mod apk files.
http://duohacks.com/how-to-mod-apks/. Anyone know what he means by "Apk signer?" thanks
(BTW I have no relation to the Robert on that site I just happen to share his name lol)

Hi Robert,
Well your question doesn't appear to be gE specific nor its something that has rare info on web. You should have googled it.

Even then here is your answer-
