Material-Animations is a Java-based library for coordinating activity transitions, property animations, and reveal effects within Android mobile user interfaces. It provides a framework for automating visual updates whenever view properties or layout configurations are modified.
The project implements high-level patterns for shared element transitions, linking independent views across different sections to simulate a single moving element. It also includes circular reveal masking to unveil content from a specific focal point and coordinate-based view mapping to execute translation and scaling movements between activities.
The library covers a broad range of UI orchestration capabilities, including scene-based state interpolation, sequential transition ordering to manage enter and exit timing, and various activity transition rules such as fade, slide, and explode.
