App Editor Problem

So I tooka version of MIUI music that worked on this thing, opened it up in an apk editor, and changed some PNG images to make it look like the galaxy s3 music player. I signed the file, installed it, and all went well, but once I tried to open it it immediately crashed. The current file (unsigned) has been attached. Fixes would be appreciated because I really want this
