 - input: Replaced custom types with their `ndk` crate equivalent.
   > [!NOTE]
   > These types existed because the `ndk` crate didn't provide them in an extensible way.  Now that they have the `#[non_exhaustive]` flag and contain a `__Unknown(T)` variant to provide lossless conversions, and not to mention use an ABI type that matches how it is being used by most functions (when the original constants were defined in a "typeless" way), the `ndk` types are used and reexported once again.

+# android-games-sdk
+
+This is an imported copy of the native "prefab" source for `GameActivity` and
+`GameTextInput`, from our fork of Google's
+[android-games-sdk](https://github.com/rust-mobile/android-games-sdk).
+
+We use an external fork to track our integration patches on top of the Android
+Game Development Kit (AGDK) in a way that it is easier to update to new upstream
+versions. It also makes it easier to try and upstream changes when we fix bugs.
+
+## Updating to new agdk version checklist
+
+This is a basic checklist for things that need to be done when updating to a new
+agdk version:
+
+- [ ] Create a new integration branch based on our last integrated branch and
+  rebase that on the latest *release* branch from Google:
+
+    ```bash
+    git clone [email protected]:rust-mobile/android-games-sdk.git
+    cd android-games-sdk
+    git remote add google https://android.googlesource.com/platform/frameworks/opt/gamesdk
+    git fetch google
+    git checkout -b android-activity-5.0.0 origin/android-activity-4.0.0
+    git rebase --onto google/android-games-sdk-game-activity-release <base>
+    # (where <base> is the upstream commit ID below our stack of integration patches)
+    ```
+
+- [ ] Set the `ANDROID_GAMES_SDK` environment variable so you can build
+  android-activity against your external games-sdk branch while updating.
+- [ ] Re-generate the `GameActivity` FFI bindings with `./generate-bindings.sh`
+  (this can be done with `ANDROID_GAMES_SDK` set in your environment and also
+  repeated after importing)
+- [ ] Update [build.rs](../build.rs) with any new includes and src files
+- [ ] Update the `src/game-activity` backend as needed
+- [ ] Push a new `android-games-sdk` branch like `android-activity-5.0.0` that
+  can be referenced when importing a copy into `android-activity`
+- [ ] Review and run `./import-games-sdk.sh` when ready to copy external AGDK
+  code into this repo
+- [ ] Clearly reference the branch name and commit hash from the
+  `android-games-sdk` repo in the `android-activity` commit that imports new
+  games-sdk source.
+- [ ] Update CHANGELOG.md as required
