Hover
A floating menu library for Android
...Hover’s architecture allows developers to easily customize behavior and appearance by extending its base classes such as HoverMenuService, HoverMenu, and HoverView. The framework also includes tools for managing hover menus as foreground services, improving compatibility with Android O and later versions. With support for direct instantiation via code or XML, Hover enables flexible integration into a variety of Android UI structures. While still in beta and subject to API changes, it offers a robust, modular foundation for creating multitasking-style floating interfaces in Android apps.
