As I noted in the Github Readme, this tool will not generate code that you will able to REcompile. My tool does a lot of things, but straight-up repackaging/ripping off other people's apps is exactly what apk2gold is bad at.
Totally agree with everything you just said! I'm not down on Smali; obviously its incredibly powerful because you can tweak and baksmali. I just personally have no need to modify and rebuild Dalvik.
thats totally sweet. Actually had not seen that, which is surprising considering the research I've been doing for this project. Thanks for the heads up!
It doesn't even decompile to "useable" code, but it does compile to code that will give you the gist of what what the intention was and what the actual commands are.
Decompilation to java is still a lossy process; if you want a non-lossy process you can check out APKTool which will encode/decode Smali (a Dalvik VM representation/assembly lang). But then you have to learn Smali...
So I have not actually used V10S (dont have a windows machine for one thing), but my impression is that it was only for smali code. This decompiles to Java, and its for Linux/OSX.
I would say that V10S is for small modification/hax, and java decompilation is for understanding how people did things/what they are doing.
