## Description

Lottie-android is a native vector animation engine and library for Android that parses JSON specification files into high-fidelity animations. It functions as a JSON animation parser and renderer, translating After Effects exported data into native draw calls to maintain design fidelity on mobile devices.

The library supports dynamic user interface control by allowing the modification of animation properties, such as colors, text, and shape attributes, during runtime playback. It also integrates with system-level accessibility settings to adjust playback and visibility in accordance with reduced motion preferences.

The engine covers a broad range of rendering and management capabilities, including complex vector graphics with masks and mattes, playback control for speed and repetition, and embedded image decoding. It optimizes mobile assets through composition caching and multi-source loading from local assets, URLs, or compressed archives.
