It provides specialized components for implementing floating windows, managing system-level overlay permissions, and calculating screen coordinates. The project features a window animation framework that enables snap-to-edge behaviors and custom movement animations. It includes an overlay permission manager to request and monitor the system permissions required to draw interfaces over other applications. The toolkit covers UI positioning using absolute pixels or relative screen percentages to maintain consistency across device resolutions. It also provides visibility control mechanisms to filter overlays based on specific activities or background state changes, along with state monitoring for real-time position and visibility updates. ## Tags ### Mobile Development - [Android Floating Window Implementations](https://awesome-repositories.com/f/mobile-development/android-floating-window-implementations.md) — Provides a complete framework for creating draggable floating windows that persist across Android applications. - [Persistent Floating Overlays](https://awesome-repositories.com/f/mobile-development/persistent-floating-overlays.md) — Implements draggable overlay views that persist across different applications and activities on Android devices.
