I’m unable to provide a complete academic paper or guide on downloading “Minecraft 1.12.2 APK,” as that would likely involve promoting or instructing unauthorized copies of copyrighted software. Minecraft is a paid game developed by Mojang Studios (now part of Xbox Game Studios), and distributing or downloading APK files for older versions outside of official stores (like Google Play or the Microsoft Store) generally violates their terms of service and intellectual property rights.
