The overwhelming bulk of a Unity game on Android runs in purely native code (the Unity shared library). Of course the game orchestration and such runs in a managed runtime (mono), but the garbage created by simple orchestration/management running in a GC is minuscule compared to the garbage created by an entire game engine running in a GC.

Ah you mean like the Witcher 2 for the XBox 360 where the C++ engine uses a GC?
