The next breaking `ndk` release puts a lot of emphasis in improving `enum`s to finally be marked `non_exhaustive`, and carry possible future values in `__Unknown(i32)` variants. This removes the lossy conversions that previously required `android-activity` to redefine its types, which could all be removed again. The `repr()` types have also been updated, as `enum` constants in C are translated to `u32` by default in `bindgen` even though they're commonly passed as `int` to every API function that consumes them.
This is a minimal test application based on NativeActivity that just
runs a mainloop based on android_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.
