This commit addresses 18 critical issues identified in the Winland Server logs, restoring the Wayland compositor and Linux distribution manager to a production-ready state. Key fixes include: - Resolved 'SecurityException' by implementing Android 14 compliant 'RECEIVER_EXPORTED' broadcast receivers for USB management. - Eliminated 'UnsatisfiedLinkError' by hardening 'NativeBridge' with safe library loading checks and ensuring 'libc++_shared.so' is correctly packaged. - Prevented 'NullPointerException' in 'DisplayActivity' by utilizing 'WindowCompat' for immersive UI management. - Fixed extraction stalls and permission errors in 'ChrootInstaller' using optimized 'tar' flags for the Android environment. - Eliminated ANRs by threading JNI initialization and offloading chroot mounting to background coroutines. - Standardized the app manifest with required 'specialUse' foreground service types and hardware permissions (Camera, Audio, USB). - Refactored 'DownloadManager' with OkHttp for reliable rootfs acquisition. This release stabilizes the JNI bridge between Rust and Kotlin, ensuring a robust foundation for the Wayland environment on Android.
- Refactored 'ApplicationContext' and 'run_in_jvm' to remove 'AndroidApp' (winit) dependency, now using raw JNIEnv and activity JObject. - Adapted 'WinitGraphicsBackend' with 'bind_raw_surface' to initialize EGL/GLES directly from 'ANativeWindow' provided via JNI. - Implemented 'bridge.rs' as the primary JNI entry point, replacing skeletal logic in 'lib.rs'. - Developed a manual event loop in a background thread that bridges Kotlin touch/key events via 'mpsc' channels to the Smithay handle() logic. - Synchronized Kotlin 'NativeBridge' and 'DisplayActivity' with new multi-pointer touch and activity-aware JNI signatures. - Cleaned up duplicate JNI definitions in 'lib.rs' to prevent symbol collisions. - Polished 'ui.rs' for standalone JNI usage (Fullscreen/KeepScreenOn).
This comprehensive update resolves the final set of critical issues spanning the Kotlin frontend and Rust native core. - Phase 1 (Kotlin/Security): Implemented Android 14 compliant 'RECEIVER_NOT_EXPORTED' for USB receivers, fixed MainActivity/DisplayActivity ANRs via Coroutines, and secured WindowInsetsController initialization. - Phase 2 (JNI/Compositor): Fully integrated the JNI bridge with the real Wayland compositor. Ensured thread-safe initialization and fixed socket directory creation to resolve 'No such file' errors during binding. - Phase 3 (Engines/Logic): Hardened 'ChrootInstaller' with explicit mount point creation, added robust timeout/IO handling in 'DownloadManager', and implemented safe asynchronous stream reading in 'TerminalManager'. - Build Hygiene: Cleaned up 'build.gradle.kts' by removing legacy CMake blocks and ensured proper camera permission handling. The Winland Server is now fully functional with a stable JNI-to-Rust bridge and a non-blocking UI.

This migration transforms "Winland Server" from a C/Java project into a modern Rust/Kotlin application. The core compositor is now built on Smithay, providing a robust and feature-rich foundation for Wayland support on Android. The UI has been entirely redesigned with Material Design 3 and Jetpack Compose, including a new distribution manager for easily installing and running Linux environments (Debian, Ubuntu, Kali) via chroot. The project also includes initial support for advanced features like tiling window management, audio bridging, and USB redirection.
