Weird. I can always upload the file as the pkg file, but I would recommend your trying to use a PC to unpack the file first, sometimes android can be finicky to unpack zip files. @_@
Sorry for the insane delay mate, work is being hard on me.
Android DO have .zip and .rar software, you can unpack the files in your android by installing an app to do that for you first, then you can run the .apk file.
