+This is a minimal test application similar to `agdk-mainloop` that
+is based on `NativeActivity` instead of `GameActivity`.
+
+It shows how to run a mainloop based on `native_activity::poll_events()` and
+traces the events received without doing any rendering. It also saves and
+restores some minimal application state.
+
+Since this test doesn't require a custom `Activity` subclass it's
+optionally possible to build this example with `cargo apk`.
+
+The idea here is to test whether we can have a `NativeActivity` based
+glue layer which is API compatible with `game-activity`, which can
+optionally be used for _very_ basic tests/demos that want the convenience
+of not needing to compile any Java code.
