## What it is
Grav is an Android library for creating configurable point-based animations using composable generators for points, drawing, colors, and animation. It is configured via XML attributes and renders effects like waves, paths, and particle fields in custom views.

## Use cases
- create particle animations in android apps
- animated login screen background android
- wave animation custom view android
- point-based animation library for android
- animated background effects in xml

## When to choose
- you need declarative, XML-configurable animated backgrounds on Android
- you want composable generators for points, colors, and animations
- you need lightweight particle or wave effects without writing custom drawing code

## When to avoid
- you need cross-platform animations outside Android
- you require a maintained library with active releases
- you need complex physics-based or GPU-accelerated animation systems

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components
- domain: mobile-development, graphics
- platform: -
- tags: android-view, particle-animations, custom-view, xml-configurable, android, mobile
