Hello everyone, I wonder is there a tool that can find functions depend on the type of input and output 😅?

I’ve decompiled an apk and I cannot see the function names in the apk source code. I guess the functions are Android build-in functions.

What do you mean “I cannot see the function names”? There are always function names in APK (even if they are obfuscated)
How did you decompiled it?

[Hank]

Sorry, I didn't describe it cleanly. I can see the original function names, the names will be like a, b etc. So I want to find the functions by the type of input and output.

I was using the APKTool to decompile APK and using Jadx-gui as my IDE to view the decompiled code.

[gildor]

yep, they are obfuscated

I don’t know such tool, except if you decompile to java and use IDEA Structural Search

Thanks for replying 🙂

BTW, is there a way to decompile APK to java code but smali code?

[gildor]

Decompile smali to Java?

[gildor]

btw, maybe for your use case would be even easier just decompile to smali and then do simple string search by all files

[gildor]

something like \.method .*($INPUT_TYPE)$RETURN_TYPE (not a valid regex, just a pseudocode

[Hank]

That's a good suggestion. Thanks a lot 😊
