Default [Q] Can you edit/replace the classes.dex on the phone?
I am trying to edit an application however whenever i use apktool (apk manager) or smali/baksmali (jarsigner etc), sign then reinstall the app crashes..

So i am wondering if i can install the untouched package and then edit/replace the classes.dex while it is already installed?

Is that possible? Where exactly do installed apps reside? or do they remain in apk format until run on the phone?

I did search though i couldnt find an answer

Thanking you in advance.
