mansheman/Userfull-mobile ? reverse-engineered prompt

Build me a Java based Android mobile security practice project that feels like a hands on learning repo. I want separate areas for dynamic analysis, static reverse engineering, mobile forensics, and a safe offensive testing sandbox. Add a few simple demo apps or sample files that show suspicious or risky behavior in a clearly simulated, non harmful way so I can inspect them and learn what to look for.

Please make it easy for a beginner to open the repo and understand what each area does, how to run it, and what they’re supposed to observe. A short guide in each section is enough, plus any basic setup steps and expected results. Keep the examples educational and self contained, not real malware or anything unsafe. Use sensible defaults where details are missing, and feel free to check current Android and Java docs online if needed.
