• Update Android CMake args to use -DANDROID_PLATFORM=<sdkVersion>

• [nitpick] Add a comment explaining why 24 was chosen (e.g. matching the community template’s minSdkVersion) so future maintainers understand this default.

const DEFAULT_ANDROID_SDK_VERSION = "24";

• [nitpick] Clarify in the help text that this flag sets the Android platform API level (e.g. 'API level for Android builds'), not the SDK tools version.

• Consider adding a unit or integration test to ensure the --android-sdk-version option is parsed and propagated correctly.

• [nitpick] Remove or document the commented-out CMake flags related to ANDROID_NATIVE_API_LEVEL if they’re no longer needed to keep the codebase clean.

    `ANDROID_ABI=${architecture}`,

• Also verify that the SDK platform directory (e.g. ${ANDROID_HOME}/platforms/android-${sdkVersion}) exists and, if missing, suggest running sdkmanager --install "platforms;android-${sdkVersion}".

I'm assuming this option is here so that higher-level tooling (RN CLI?) can pull the mininmum SDK version from the user's Gradle files, is that correct?

It's mostly for the library developer to pick, but it's only really needed if someone is calling into Android APIs from their native addon. The reason I added now is just to silence a warning - I should have probably made that clear from the description 😊
