Game Development with Unity from an Android Point of View
summary
Unity on Android uses JNI-bound plugins written in Java/Kotlin or C/C++; developers must call System.loadLibrary, follow JNI naming, and expose C++ functions with extern/JNIEXPORT to interop. Unity exports a Gradle Android Studio project (check “export project” and include source) and supports adding Java/Kotlin in Assets/Plugins/Android since 2018.2. More than 50% of new mobile games use Unity; Unity as a Library (2019.3+) embeds Unity into apps but is full‑screen only, disallows multiple instances, can bloat APKs, and communicates via UnitySendMessage.
