This project is born because there isn't any reliable way to convert a bunch of smali files into something you can really import into eclipse and compile away. I've lost a few projects in a recent 1 TB HDD crash and man, it wasn't pretty to see I couldn't even get them back with JD-GUI or something. I've done the same with a few .NET projects of mine, so why can't I on Android? you can, but sometimes the tools (JD-GUI or JAD) go nuts and attempting to fix them just gives you a headache so...
Being a smali modder for quite some time, I managed to realize that the entire smali code, if analyzed correctly, it can be converted back to java. We mentally do it when we make smali mods, all I'm attempting to do is to automate the process and make it easier for everyone. Also, it would be really useful to be able to recompile a few Jars and APKs in order to fix device bugs (which is also another reason why I'm working on this).
Some of you would say there is already JD-GUI and JAD, but they're not a real true 1:1 conversion and also most of the times they're not compile-able. Also, There's JEB Android Decompiler but no way I'm gonna pay such a price for something I've been doing mentally and that I can automate with a script made in about a week or a few months. The tool could be great, but the price is too high and my own country's restrictions don't allow me to buy it even if I ever get the money.
The idea here, is to make an app that can translate Smali to Java, directly. Of course, it requires a bit of analysis. It needs to analyze the class directives, the methods and their prologue (parameters, declaration, etc), class annotations and method instructions. So far, I've managed to develop most of the analyzer with a few basic instructions set up for demo purposes.
Of course, I know it needs a bit more work: some variables/instructions don't appear, types are incomplete or missing, etc. But that's why I'm here: I can work on this alone, but, first, it wouldn't be fair. Also, I'm human and by default I have bugs, so I might skip something and make the code go bogus and stuff. And finally, I'd like to request the help of the community. I made this project to see if there's enough attention and contribution from the smart people here, and if there is, I'm gonna give it all to make this project do what it says, 100% error-free.
Note: IT NEEDS .NET FRAMEWORK 3.5. Yeah, and VS 2012. I assume you can make it work with VS2010 or I can make a version soon if there's enough interest, or heck, even Mono as long as it has Linq (I make heavy use of it). The idea is to make a good, open-source parser you can compile even on an arduino with Mono and it will work. But for now, this will have to do. It is my own code and I decided to share it to see if there's interest. If there's enough, I'll do everything I can to provide the tools needed for you guys to help me make this project a reality.
Also, it seems it works with SharpDevelop, so you can compile it under Linux too! :)
