LGLTeam/Android-Mod-Menu — reverse-engineered prompt

Build me an Android floating mod menu template for educational offline game modding experiments. I want a small demo project that compiles in Android Studio, opens a movable floating menu over a native Android game or test target, and lets me add simple toggles, sliders, buttons, and spinners without editing lots of UI files.

It should support Android 4.4 through current Android, both ARMv7 and ARM64, and keep menu images or assets embedded so I don't have to manage an assets folder. Include the native C++ side for il2cpp and other native targets, with common memory and hook helpers wired in, but leave the actual game offsets as safe placeholders and examples only.

Please add clear comments and a simple docs guide showing how to add a new menu item, request overlay permission, build the APK, and troubleshoot common crashes. Keep it educational and don't add anything aimed at online cheating.
