Hover

Hover is an open source floating menu framework for Android, developed by Nest Labs (a Google company), designed to help developers integrate interactive, persistent floating menus into their mobile applications. It provides a complete out-of-the-box implementation for overlay menus that can expand, collapse, and dynamically update content without disrupting the main user interface. 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.
