igorwojda/android-showcase

This is an Android showcase application built with Jetpack Compose, featuring a modular architecture that separates concerns into album, favourite, and settings domains. It implements a clean architecture with explicit use cases, repositories, and ViewModels, supported by a modernized Gradle build system using convention plugins. The app provides UI for browsing albums with local caching, managing favorites, and viewing open-source licenses, all underpinned by comprehensive unit and static analysis tests.

6 changes.

The period marks the initialization of the Android 2.0 showcase app, establishing its documentation, code of conduct, and modern architecture using Jetpack Compose and Koin. Concurrently, the project underwent a significant build system overhaul, migrating from a legacy Gradle configuration to convention plugins and type-safe accessors, while updating the Gradle wrapper and ProGuard settings.

15 changes.

This period focused on implementing the album feature, including its domain, data, and presentation layers using Jetpack Compose and Room. Simultaneously, the codebase established standardized build logic, test utilities, and static analysis rules to support future development.

The Settings feature now includes a Settings screen that displays an 'Open Source Licenses' option, and an About Libraries screen that uses the LibrariesContainer component to display third-party library information. This introduces new UI components, view models, and Koin modules for both screens, enabling users to view open source licenses directly within the app.

The settings feature now includes the necessary Android manifest and ProGuard configuration files, along with a new strings resource file. This adds the UI text for the main settings screen (title, about, open source licenses) and the about libraries screen (title, back navigation), enabling the display of these interface elements to the user.

The album and favourite feature modules were initialized with essential configuration files. Each module now includes a ProGuard rules file for code shrinking and obfuscation, an AndroidManifest.xml file defining the module's manifest, and, for the album feature, a strings.xml file containing UI text resources such as search hints, titles, and content descriptions. These changes establish the foundational structure for these features within the application.

feature/album · high confidence

The album feature now implements a data layer that caches album information locally using Room, allowing the app to retrieve album data from the database when the network is unavailable or after an error occurs. This is achieved by adding API response models, a Room database with DAOs, mappers for converting between API, Room, and domain models, and a repository implementation that falls back to the local cache. Additionally, Koin modules are added to wire the data and presentation layers, including ViewModels for the album list and detail screens.

Adds a new set of reusable Compose UI components including \ErrorAnim\, \LoadingIndicator\, \LabeledAnimation\, \PlaceholderImage\, \TextTitleLarge\, \TextTitleMedium\, and \UnderConstructionAnim\. Additionally, introduces a base \BaseViewModel\ with state time-travel debugging, a generic \ApiResult\ sealed interface for handling network responses, and supporting resources like dimensions, colors, and string constants.

The build-logic module now includes a set of new Gradle convention plugins that standardize the configuration for Android application and library modules. These plugins automatically apply and configure essential tools and dependencies, including the AboutLibraries plugin (with duplicate merging enabled), KSP, Compose, and various utility plugins like Detekt, Spotless, and EasyLauncher. The changes ensure that all Android modules share a consistent baseline configuration for SDK versions, build features, and common dependencies.

The library/test-utils module now includes JUnit 5 extensions to simplify testing asynchronous code. CoroutinesTestDispatcherExtension replaces the main coroutine dispatcher with a test dispatcher, while InstantTaskExecutorExtension forces synchronous execution of Architecture Components tasks. These utilities help developers write deterministic tests for background operations.

The repository was initialized with essential project documentation and configuration files. This includes a comprehensive README detailing the Android 2.0 showcase app's architecture, tech stack, and usage; a DeveloperReadme covering known issues with tools like Detekt, Gradle, and Kotlin; a Code of Conduct; a Contributing guide; and configuration files for code quality (EditorConfig, Detekt, .gitignore) and automated dependency updates (renovate.json).

(repo-wide) · high confidence

The project's build system has been restructured to use Gradle convention plugins, moving common build logic from \buildSrc\ into a dedicated \build-logic\ module. This introduces type-safe project accessors (e.g., \projects.feature.base\) and a centralized \libs.versions.toml\ catalog for dependency management. As a result, individual module \build.gradle.kts\ files are significantly simplified, and the root \build.gradle.kts\ now applies these convention plugins to all subprojects.

(dependencies) · high confidence

The album feature's domain layer has been reorganized to introduce a clear separation of concerns. A new \AlbumRepository\ interface defines the data access contract, while \GetAlbumListUseCase\ and \GetAlbumUseCase\ encapsulate the business logic for retrieving album data. This structure supports the album functionality by providing distinct entry points for listing and detailed views, leveraging Koin for dependency injection via the newly created \AlbumKoinModule\.

The album list and album detail screens have been rewritten using Jetpack Compose, replacing the previous Fragment-based implementation. Users will now see a modern UI for browsing albums in a grid with a debounced search bar, and viewing album details including cover art, artist name, tags, and track lists. The implementation introduces new composables for the search bar, album grid, and album detail view, along with corresponding ViewModels and UI state models.

The Favourite feature has been restructured to separate concerns into distinct Koin modules for data, domain, and presentation layers, each defined in its own file. The presentation layer now includes a Compose-based FavouriteScreen that displays an 'Under Construction' animation, reflecting the initial state of this feature.

The app's main entry point has been replaced with a Compose-based \MainShowcaseActivity\ that utilizes a \NavHost\ for declarative navigation between screens, replacing the previous \MainActivity\ and XML-based layouts. A \BottomNavigationBar\ has been added to the main screen, providing navigation to Albums, Favorites, and Settings. The application now initializes Koin for dependency injection and configures OkHttp interceptors for network requests. Additionally, the app icon has been updated to support adaptive icons with monochrome variants, and the theme has been migrated to \Theme.Showcase\ with splash screen support.

app/src · high confidence

The buildSrc module's Kotlin files defining application configuration, core versions, Gradle dependencies, library dependencies, and module dependencies have been deleted. This removes the centralized version and dependency management from the build script, likely as part of a broader migration to a different dependency management approach.

buildSrc · high confidence

The app's ProGuard configuration files were updated to reflect a shift in the build system: the proguard-rules.pro file now references build.gradle instead of build.gradle.kts, and the .gitignore file was removed from the app directory.

app · medium confidence

Added domain layer tests for album feature; Added static code analysis tests for Android, Clean Architecture, and general coding standards; Added tests for album data layer mappers and repository; Added unit tests for album feature ViewModels; Added unit tests for settings view models.

The Gradle wrapper has been upgraded from version 4.10.2 to 9.4.1. This update changes the distribution URL to the 'bin' variant instead of 'all', and adds network timeout and distribution validation settings to the wrapper configuration.
