Extending Android XR’s Reality
summary
Claims that existing Android apps run largely unchanged in XR while spatial features require only a few APIs; uses Jetpack XR plus Kotlin Compose, ViewModel, Retrofit and kotlinx.serialization to fetch a Blue Sky "cats" feed and layout posts in a cylindrical ring. Demo runs in the Android XR emulator (Mac/Win controls) and uses a normalized-angle cosine math to position items; result: emulator demo works and shows windows and orientation controls, but hardware is pending and some apps (YouTube) and camera/orientation edge cases still break.
