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
First up: this isn't criticism of the original post in the slightest, it's a wonderful journey through figuring out how a weird device that wants to be on your wifi works. If you have a device that speaks to an Android app, you want https://github.com/niklashigi/apk-mitm will turn an apk into something that approximates Java, and digging through that will often let you figure out what the key is. But some vendors... - 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
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

I'm 18M Indian. Growing up I've always been a daydreamer, if you may. Since 8th grade - I'm fascinated by programming. And I'm good at it too. But I'm not cocky too. I wouldn't say I'm at an advanced level, but I can most probably solve any problem - in time - with my skills. I also keep my skills brushed by solving problems on Hacker Rank (every day or alternate days) and try my best to contribute on... Source: almost 3 years ago
