 ## [Unreleased]
 
+- 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 result in lossless conversions, and not to mention use an ABI type that how its used by most functions (when the original constants were defined in a "typeless" way), the `ndk` types are used and reexported once again.
+
+  > [!IMPORTANT]
+  > **Relevant breaking changes**:
+  > - `repr()` types for some `enum`s have changed to match the type that returned and consumed by functions interacting with this wrapper type.
+  > - `Source::is_xxx_class()` functions are replaced by querying `Source::class()` and comparing against variants from the returned `SourceClass` `bitflags` enum.
+  > - `SourceFlags::TRACKBALL` (from `Source::is_trackball_class()`) is named `SourceClass::NAVIGATION` in the `ndk`.

 - Avoids depending on default features for `ndk` crate to avoid pulling in any `raw-window-handle` dependencies ([#142](https://github.com/rust-mobile/android-activity/pull/142))
 
-    **Note:** Technically, this could be observed as a breaking change in case you
-    were depending on the `rwh_06` feature that was enabled by default in the
-    `ndk` crate. This could be observed via the `NativeWindow` type (exposed via
-    `AndroidApp::native_window()`) no longer implementing `rwh_06::HasWindowHandle`.

-    As far as could be seen though, it's not expected that anything was

-    The benefit of the change is that it can help avoid a redundant

 - The IO thread now gets named `stdio-to-logcat` and main thread is named `android_main` ([#145](https://github.com/rust-mobile/android-activity/pull/145))
