Skill: Key Libraries and Frameworks
Overview
AniTrend v2 uses a combination of standard Android Jetpack libraries and in-house support
libraries. All versions are centrally managed in gradle/libs.versions.toml; use the generated
libs.* accessors rather than hardcoded coordinates.
For AniTrend's repo-specific Android wrappers around system services, theme/configuration helpers,
notifications, deep links, and app-shell behavior, read
.agents/skills/android-platform-patterns/SKILL.md before adding a new helper API.
Jetpack components
- Lifecycle + ViewModel — lifecycle-aware holders for UI state.
- Room — SQLite ORM; entities, DAOs, and migrations live in
:data:* modules.
- Paging —
PagingData / Pager drives infinite-scroll lists; reuse the existing setup
rather than building a custom scroll mechanism.
- WorkManager — schedules background jobs in
:task:* modules.
- Navigation Compose — drives screen routing via
NavHost; see :app:navigation.
In-house support libraries (via JitPack)
All versions are declared in gradle/libs.versions.toml.
| Library | Purpose |
|---|
support-arch | Base classes for DataState, UiState, data sources, ViewModels, UI state layout |
support-query-builder | Schema-aware DSL for composing GraphQL and Room SQL queries |
support-markdown | Markwon wrapper for rendering Markdown-rich content |
Networking
- Retrofit + OkHttp — HTTP client; shared configuration injected by
buildSrc.
retrofit-graphql — AniTrend's custom Retrofit converter for GraphQL requests.- Kotlinx Serialization — JSON serialization; configured alongside Retrofit.
- Chucker — Debug HTTP traffic inspector; only included in debug builds. Before modifying
a serializer, response mapper, or UI data assumption that depends on a live API response,
inspect the response recorded by Chucker in the debug build to confirm the actual payload shape.
Image loading
- Coil — Configured in
app/core/src/main/kotlin/co/anitrend/core/koin/Modules.kt with
GIF, SVG, and video-frame support plus tuned memory/disk caches. Use the Koin-provided
ImageLoader singleton rather than creating ad-hoc loaders.
UI and theming
- Material3 Compose — primary design system; use
MaterialTheme tokens for colors and
typography.
- support-arch theme —
AniTrendTheme3 and PreviewTheme wrappers; apply them in
composables and previews.
- AniTrend Android core UI —
:android:core owns repo-specific theme, configuration, helper,
and Compose utility surfaces consumed by the app shell and feature modules.
- android-emojify — Emoji parsing/rendering exposed as
EmojiManager singleton via Koin;
registered in app/core/src/main/kotlin/co/anitrend/core/koin/Modules.kt.
Dependency injection
- Koin — loaded at startup via
InjectorInitializer. See .agents/skills/koin-module-wiring/SKILL.md
for wiring conventions.
Logging and analytics
- Timber — added globally; use
Timber.d/e/w instead of Log.* or println.
- Firebase Analytics + Crashlytics — enabled only in the
google product flavor via
buildSrc plugin logic. Always gate analytics calls behind a flavor check. If an analytics
helper exists, prefer it over a raw flavor check; if no helper exists, use BuildConfig and
leave a TODO to extract a helper.
Testing
- JUnit 4 — base test runner.
- MockK — Kotlin-idiomatic mocking; prefer mocking interfaces over concrete classes.
- Turbine — Flow testing; use
turbine to assert emissions from DataState flows.
- kotlinx-coroutines-test —
runTest, StandardTestDispatcher, or
UnconfinedTestDispatcher for coroutine tests.
- Test dependencies are auto-added to every module by
DependencyStrategy.kt; no manual
declaration needed.
