Possible disadvantages of Bytecode Viewer

  • Performance Issues
    Some users have reported performance issues, particularly with large files or projects, which can lead to slower analysis and increased resource usage.
  • Limited Support for Other Languages
    While Bytecode Viewer excels with Java and Android bytecode, it doesn't support other programming languages, which might limit its utility for developers working in diverse environments.
  • Complexity for Beginners
    Despite its user-friendly interface, the complex nature of bytecode and reverse engineering might overwhelm beginners without enough support or guidance within the tool itself.
  • Dependency on Java Environment
    Since Bytecode Viewer is Java-based, it requires a Java Runtime Environment to be installed and configured correctly, which might add an extra step for users who do not have Java set up.
  • Occasional Bugs
    As with many open-source projects, Bytecode Viewer can sometimes have bugs that might affect its stability or functionality, depending on its version and the system it's run on.

Possible disadvantages of JADX

  • Limited Obfuscation Handling
    While JADX can handle some obfuscation, highly obfuscated code can still pose challenges, affecting the readability and accuracy of the decompiled source.
  • Resource Intensive
    JADX can be resource-heavy during decompilation, which may lead to performance issues on lower-end machines or when dealing with large APK files.
  • Incomplete Code Conversion
    In certain complex cases, Decompiled Java code might not always compile back perfectly due to incompleteness or inaccuracies in the conversion process.
  • Limited Interactive Debugging
    JADX lacks sophisticated interactive debugging features, which can make it challenging to analyze dynamic behavior or runtime issues.

    If you do find an .apk and didn't obfuscate it with proguard (I can't remember if proguard ran default in the release pipeline in Eclipse ADT...which...ew) you can use jadx to decompile your .apk and recover the structure of your source code! https://github.com/skylot/jadx. - Source: Hacker News / 11 months ago

    > I remember something like dex2jar also, which gave you a jar you could use in any java decompiler, like jdgui, procyon etc. https://github.com/skylot/jadx is very handy for that nowadays. It also supports interactive variable/method/class name renaming to make the decomplied code easier to read. The decompiler isn't perfect, but I guess all available Java decompilers... - Source: Hacker News / over 1 year ago
  • Hunting the Hacker: A Deep Dive into Courier Fraud
    Suspicious of the request, our colleague forwarded the APK to me, knowing my expertise in software development and cybersecurity. My investigation began by downloading and extracting the contents of the APK. Inside, I found several dex files, which I knew contained the app's compiled source code. Using a tool called jadx, (jadx -d extractedapkfile) I decompiled the APK to inspect its source code. - Source: dev.to / almost 2 years ago
