Manually copy and paste the folder

@flamecopper Could you specify which folder needs to be copied to where? I assume after building the apk you're saying there's a folder in the exploit apk folder that needs to be copied over to some place in the Android filesystem?

This seems to be broken in all qark versions from 2.x through 4.0.0. Tested them all.
