I'm getting [INSTALL_PARSE_FAILED_UNEXPECTED_EXCEPTION] when I extract
the .smali files from the classes.dex, and then recompile the .smali
files into my own classes.dex-- EVEN IF I DON'T MODIFY THE .SMALI
files. There is either an issue with extraction or compilation
(maybe both)-- and I've tried several programs, and several methods.

EDIT: http://leonjza.github.io/blog/2015/0...mali-patching/

Shows me that it has something to do with the signature. I'll see what
I can do.

EDIT: Further research shows
https://www.herongyang.com/Android/Pr...rtificate.html that I MIGHT
have to somehow get the certificate to work with the modified file
properly. God help me now. I assume I'm not the first person to run
into the certificate roadblock. Must find a way.

For all the heavens I can't seem to find a way to edit the .dex file
in a way that leaves the certificate intact-- I suppose this is why
the system was developed in the first place. Back to square one again,
I suppose. (Or to giving up and buying a XTC 2 Clip)
