I have the apk of a legacy photo-editing Android app with 32-bit-only native libraries, so recent devices cannot install it. I don't have the original project files, only the APK, so the job involves decompiling or otherwise extracting what you need, rebuilding the native components for 64-bit (arm64-v8a, and ideally x86_64), and repackaging everything so the behavior, UI, and performance (to a lesser degree) remain unchanged. No code or functionality needs to be added or changed beyond the simple ability to get it installed on my device. You are free to use jadx, apktool, Android Studio, NDK, or any other tools at all, the only thing that matters is that the finished package installs and runs on my 64-bit Galazy S26 Ultra phone. I have no intent to ever release it as a public app, o...
