Foundation milestone (REDI-78, REDI-79):
- Multi-module skeleton: :app, :core:{domain,data,presentation,design-system},
:feature:characters:{domain,data,presentation,presentation-compose,presentation-views},
:feature:about:presentation, plus the :build-logic composite build.
- gradle/libs.versions.toml as the single source of truth ([versions]/[libraries]/
[bundles]/[plugins]); no inline versions in any build file.
- Convention plugins: architecture.android.{application,library,feature,feature.views},
domain.module, compose, koin, ktor, kotlinx.serialization.
- Pure-Kotlin domain modules; presentation-compose uses android.feature;
presentation-views uses android.feature.views (ViewBinding on, Compose off);
the UI-agnostic :presentation has neither Compose nor Views deps.
- Toolchain: AGP 9.0.1, Kotlin 2.3.20, Gradle 9.1.0, compileSdk 36, minSdk 24, Java 17.
- Minimal MainActivity placeholder; CI (assembleDebug) via GitHub Actions.
Verified: ./gradlew projects lists the full tree and ./gradlew assemble is green.
Android Architecture Showcase
A single runnable Android-only (Jetpack Compose) reference app that demonstrates good architecture conventions — each in its own module/example. Teaching repo: every module is meant to be minimal but complete and idiomatic.
Status: built milestone-by-milestone from the Linear backlog. Foundation (scaffold, version catalog,
build-logicconvention plugins) is complete and the project assembles green. Full architecture docs land with the Quality & Docs milestone.
Stack
Multi-module Gradle + build-logic convention plugins · Koin (constructor DSL) · Ktor ·
KotlinX Serialization · Coil · Kermit · type-safe Compose Navigation. Data comes from the no-key
Rick & Morty API.
What it will showcase: MVI as the primary presentation pattern (flagship characters feature),
an MVVM contrast screen, and the same MVI ViewModel driven by two renderers — Jetpack
Compose and classic XML + ViewBinding + RecyclerView — proving the presentation logic is
UI-toolkit-agnostic.
Module structure
:app → wires everything; single Activity, Compose host
:build-logic → Gradle convention plugins (the only place versions/config live)
:core:domain → Result/error types, shared domain models (pure Kotlin)
:core:data → Ktor HttpClient factory, safe-call helpers
:core:presentation → UiText, ObserveAsEvents, DataError → UiText
:core:design-system → AppTheme + reusable composables
:feature:characters:domain → models + repository interface (pure Kotlin)
:feature:characters:data → DTOs, mappers, data source, repository impl
:feature:characters:presentation → MVI ViewModel/State/Action/Event (UI-agnostic: no Compose, no Views)
:feature:characters:presentation-compose → Compose renderer
:feature:characters:presentation-views → Views/XML renderer (same ViewModel)
:feature:about:presentation → MVVM contrast screen
Dependency rules: presentation → domain ← data; domain depends only on :core:domain;
features never depend on other features; :app wires the graph.
Build & run
./gradlew assembleDebug # build the APK
./gradlew projects # print the module tree
./gradlew check # tests + lint (added in the Quality & Docs milestone)
Requires JDK 17+ (the Gradle build pins a Java 17 toolchain) and the Android SDK
(compileSdk 36, minSdk 24).
