Does it have linux support? If not I can always try VM.

Unfortunately not, Maybe I will make a new version for linux also (I think all the external programs also so support linux)

Can the Java code be run in an application, browser perhaps? As in, running the app on your computer?

No, this is no javascript, but java. You can run it in Eclipse for example

Not to take anything away from the work you've done. But just so other's aren't confused, this is just an automated script/GUI for existing tools. It simply runs dex2jar, apktool, baksmali, etc.. I came into this hoping it was maybe a different decompiler, a better one that might do a better job of de-obfuscating the code. But seeing that it's just an automater/GUI takes away from that.

Great job on the automater though, and keep up the work towards your education. We all have to start somewhere. :good:

Yes that's what it does, I also mentioned the external tools used etc, so I think it's already clear that I didn't create an actual APK to Java decompiler, which would take me my whole life to only make a beta version :')

I used the most accurate tools, to bad JD-Core isn't available, really hate to work with a unnecessary gui which is also not fully controllable for some reason.

This looks amazing!

I'm having an error though,

Thanks!

Thanks, In the current git commit (Early RC1) this problem is fixed. (Some one else mentioned it also, but It's kind of strange I think because I never received any error like that. however, it's fixed now.. (in the commit at least)
Will release RC1 probably today

first: thx for your great effort and work!
one question though: so this does not produce usable and compilable java-code, right? so we can not use this tool to decompile for example a SystemUI.apk, apply our mod to the produced java-code and then recompile it to a working SystemUI.apk?

greetz n thx,

You're welcome!, Well actually, It does generate a usable code, but it needs to be edited a little in most cases, I think all apks that are specially built for specific devices such as SystemUI.apk won't work without modifying some code.
for example, when you want to port a function from an other SystemUI.apk just decompile it, look up the source and paste it in your SystemUI.apk, probably it will have some errors because of invalid variable names or such, but the actually code just keeps intact, so that's the most important thing.

Im new to thread. I've used dex2jar years ago for help with my java II class making android apps for school. So does this just use dex2jar and some other tools to decompile with a GUI. Does this let you put it in eclipse and recompile?

Basically it's an automated gui for several external tools yes, I'm still working on the Eclipse function to make the output less buggy, I think making an actual working eclipse project from an apk is the biggest challenge, But remember this is only a beta, so many new versions will release

Looks amazing, this will really come in handy!

Thanks! It can become very handy sometimes idd

Nothing wrong with GUI. Great job. About the eclipse portion of recompiling from source would be an elite defeat. I don't even think it can be done but with programming anything can happen. Downloaded now to check out. Just wondering if you can decompile jelly bean sys apps? Xda app sucks at search function.

Yes the eclipse thing is the biggest part, It does create an importable eclipse project but when there's a lot of code it always has errors, I used it to port some small apps worked without any problems.

And yes you can decompile JB system apps! you're interested in porting functions from JB to ICS?

And the search function is okay, but only if you use "Search in titles only". else it's rubbish

I would love to be able to try it but I get an error
I'm on windows 8 x64
I tried RC1 couldn't compile (error adding splash) but I ran it instead and same error

Click to expand...

Click to collapse

I've identified that problem, It's either your apk doesn't have any source code (like framework-res.apk) or it's because the Heapsize set by java is to large for your system, I've indicated 2gb ram as minimal requirement. but the strange thing is that I have 8gb ram and still it gave me that error (at a very early build). So I edited the heapsize (https://github.com/broodplank/APKtoJava/commit/45dcbd5a956416883ee9c0e7a06300073ed4f1ca) to fix the problem. It seems you probably need a heapsize even lower then 512mb! try it, in RC1 final you will have the option to set the heapsize trough preferences menu btw.

SinisterChedda said:

Which Java version do you have? Also try making java /bin folder as a environmental variable. I'm a little buzzed so hopefully it applies.

I think that's not the problem, I already found out the reason 2 days ago. check the post above for explanation.

I'm running java 7 update 7, also I fixed my compile error by setting an env:

Code:

EnvSet("path", EnvGet("path") & ";" & @ScriptDir) 
;Include splash image in exe
FileInstall("splash.jpg", @TempDir & "\splash.jpg", 1)

This way you can remove your absolute path and remove all the @ScriptDir & "\ from your script

[edit] I will try changing it but I have 8GB
I tried adding path to java jdk and Java_home but doesn't seems to work, I'm doing my test with cyanogenmod 10 deskclock.apk
There is nothing in preferences except 2 empty squares, so I guess it's all related to a java issue

Thanks! I didn't know that command! I will update the source with EnvSet, I chose for the relative path since Fileinstall needs a relative path, but this way is much better

And the preferences screen is still empty idd, still need to fill it ^^ easy job tho, the commented part is al I need, just some changing and it's done

snowman77 said:

Thanks . What are requirements of this? Is a certain version of windows need?

Thank you for this work

Will you or anyone mind if I rewrite it in C

Click to expand...

Click to collapse

You're welcome, the minimal requirements are currently aimed at: (from helpfile)

- Windows XP / 7 (32 bit or 64bit)
- 2GB RAM
- Java Runtime Environment 6 or 7 (or JDK 6 / 7 )

And you could rewrite it in C, but how do you want to release it? since it already exists now. with the same name and functionality? please explain.

Sorry for bad english

No, exe's don't run on linux (you could try with wine, but no success guaranteed), I will try to make a linux version if im able to. ^^

Thanks, and I did post it in Android Software Development
