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.
