## What it is
MaterialRatingBar is an Android UI library providing a Material Design RatingBar with a more consistent and correct appearance than the framework widget, compatible with Android 3.0+. It extends the framework RatingBar and works as a drop-in replacement with proper tinting, sizing, and fractional rating support.

## Use cases
- display star ratings consistently across Android versions
- replace the framework RatingBar with a Material Design version
- show fractional ratings like 4.3 correctly
- render a rating bar that fills match_parent width like Google Play Store
- customize star tint colors
- get drag callbacks while the user changes a rating

## When to choose
- you need a Material-styled rating bar on older Android versions
- the framework RatingBar shows visual glitches or incorrect half stars
- you want a drop-in replacement with minimal code changes

## When to avoid
- you are not building an Android app
- you need a rating control outside the Material Design language
- you require actively developed features beyond maintenance
