Using latest Dex2Jar : Seeing this failure " Failed resolution of: Lres/Hex " about dex2jar HOT 17 OPEN

Not seeing this exception specific to okHttp library. Observed the same issue in another apk.

Tried the same with the old version of Dex2Jar there this issue is not happening. Can you please look into it?

from dex2jar.

Hello, sorry for not responding for quite some time. I needed to finish some work for University and academic purposes.
What exactly are you trying to do? It seems like you are trying to disassemble a dex file into a jar and reassembling it into Dalvik and then trying to run the apk/dex file on an Android phone. Is that correct?

I searched for the res/Hex file everywhere, but no matter what, I can't find it. Even if you run jadx on an APK file with okhttp included, there is no res/Hex class file.

from dex2jar.

@ThexXTURBOXx No problem. Thank you for the response back.

Yes your understanding is correct, we are disassemble the dex file in to jar and then reassembling the Dalvik .

Here as you said this file "res/Hex" is not available in the final apk.
We tried including the "dex-translator/src/test/java/res/Hex.java" in the final dex file, then this error is not coming. or We have to change IR2JConverter MAX_FILL_ARRAY_BYTES to Integer.MAX

Ideally my understanding, in this class dex-translator/src/main/java/com/googlecode/d2j/dex/Dex2Asm.java addHexDecodeMethod suppose to do that. But it didn't happen. I may be wrong here, I thought it will give you idea where to look out. Sorry If I am wrong here.

We also observed this is not happening with Dex2Jar first version for the same apk. It's happening because of the changes done with Dex2Jar latest changes.

Ah I see! I forgot one small thing. Give me a second :)

from dex2jar.

Try again using version v48. Now, the method name should also be properly changed.

Okay @ThexXTURBOXx . Thank you. Will test and let you know

Thanks for your feedback! Nice to hear that this issue has been resolved.
I will take a look at the new issue as soon as possible

from dex2jar.

Thank you @ThexXTURBOXx .

If you have any further updates on the ticket, please let us know.

from dex2jar.

Yes, I will! I think the main problem is that dex2jar is not the right tool for a complete, 100% working disassembling and reassembling of dex files.
There will always be errors because of incompatibilities between both instruction sets.
Depending on what you want to achieve, it might be worth to take a look at dexlib2 or even multidexlib2 (from DexPatcher). They provide nice functionality for parsing and manipulating these files (if that is what you want to do).

from dex2jar.

Ohh okay. Thank you for the update and suggestion. Then this issue is not possible to be fixed ?
