| Scenario | Action | |----------|--------| | (e.g., scanner, HMI) | Continue with API 16 but lock device updates and network access. | | Consumer app | Migrate to minSdk 21 (Android 5.0) as a minimum – covers 99%+ active devices. | | Kiosk / digital signage | Use Android 8.1 (API 27) for better security and modern WebView. | | Automotive (Android Auto pre-2015) | Build separate APK with minSdk=16 but restrict features. | 8. Conclusion Android 4.1.2 is a functionally obsolete platform for general-purpose apps. While it is technically possible to build and run APKs on this version, the combination of security vulnerabilities, Play Store bans, missing APIs, and poor performance makes it unsuitable for new development. Only maintain API 16 support if contractually obligated for legacy hardware, and plan for a migration to at least Android 5.0 (API 21) or higher. Prepared by: Mobile Platform Analysis Team
