Convx is a free, open-source music player for Android that streams from YouTube Music, built with Jetpack Compose on a Media3 ExoPlayer core. The UI is a custom Liquid Glass design system — frosted, refractive surfaces, iOS-style bouncy scrolling, and progressive blur chrome — instead of stock Material widgets.

Convx started as a fork of vivi-music; see Credits below.

Quick map for contributors — see CONTRIBUTING.md for the full guide.

• UI: Jetpack Compose, MVVM (ui/screens + viewmodels), navigated via ui/screens/NavigationBuilder.kt.
• Liquid Glass: ui/component/GlassEffect.kt exposes Modifier.liquidGlass(...), built on a vendored, source-included copy of Kyant0/backdrop under ui/component/backdrop/. A Backdrop (usually a rememberLayerBackdrop() attached via Modifier.layerBackdrop(...) to some subtree) captures real pixels; any surface holding a reference to that same backdrop can sample, blur, and refract it through drawBackdrop(...). The floating nav bar, circular back/share buttons, and sheets are all just glass surfaces sampling a nearby backdrop this way.
• Playback: Media3 ExoPlayer service in playback/MusicService.kt.
• Data: Room database (db/) for the local library, DataStore for preferences (utils/DataStore.kt, constants/PreferenceKeys.kt).
• YouTube Music access: the innertube module — an unofficial InnerTube API client, kept separate from the app module.
• Updater: vivimusic/updater/ checks GitHub Releases for new versions and handles in-app APK download/install (FOSS/GMS build flavors behave slightly differently — see BuildConfig.CAST_AVAILABLE).
