| # | Feature | Description | Typical Implementation Details | |---|---------|-------------|--------------------------------| | 1 | | The APK should be self‑contained and capable of running directly from external storage (e.g., OTG USB, microSD). | • Use android:installLocation="auto" or "preferExternal" in the manifest. • Store all assets (textures, audio, level data) in the assets/ folder or a dedicated external‑storage directory that the app reads at runtime. | | 2 | Zero‑install launch | User double‑taps the APK on the removable media → Android prompts “Open with …” → Game launches without a traditional “install” flow. | • Target Android 8.0+ (API 26) where “instant app” style behavior can be mimicked via adb install -r from a file manager. • Provide a small “bootstrap” stub that loads the main game binary from the same storage location. | | 3 | Offline‑first operation | No reliance on network services; all assets, save data, and configuration live locally. | • Use SharedPreferences or a small SQLite DB stored on external storage ( getExternalFilesDir() ), with proper permissions ( READ_EXTERNAL_STORAGE , WRITE_EXTERNAL_STORAGE ). | | 4 | Configurable controls | Touchscreen, optional gamepad, or on‑screen joystick that can be toggled. | • Android InputDevice APIs, Gamepad support, and a custom on‑screen UI layer built with Unity/Unreal/LibGDX. | | 5 | Save‑state portability | Game progress should travel with the removable media, so a user can pick up the same save on any compatible Android device. | • Serialize save data to a file in the same external directory (e.g., saves/ ). | | 6 | Device‑agnostic scaling | The UI must adapt to a wide range of screen sizes and aspect ratios (phones, tablets, TV boxes). | • Use responsive layout techniques (constraint‑based UI, 9‑patch backgrounds, dynamic resolution scaling). | | 7 | Security & integrity checks | Prevent tampering with the APK or save files while preserving the “portable” nature. | • SHA‑256 hash verification of asset bundles at launch; optional obfuscation via ProGuard/R8. | | 8 | Legal compliance | Ensure all assets, code, and third‑party libraries are properly licensed for redistribution. | • Use only assets you own or have cleared; avoid distributing copyrighted game content without permission. |
