Alright... SO. I've encountered a problem with apktool... The apk decompiles fine without errors... but it does not recompile well...

Here's the log when recompiling framework-res.apk

I: Building apk file...

P.S. I have installed all framework files ( framework-res.apk, twframework-res.apk, and SystemUI.apk ).

P.P.S. Also keep in mind that I even tried not changing a single thing and simple decompiling then recompiling directly, still got an error.

P.P.P.S. I only used apkmanager because it gave me a nice clear log... but the same error happened with apktool

Would appreciate any form of help. Thank you ;)
