vpaliy/Music-App

This system is an Android music application that manages audio playback and media interactions. It implements a modular architecture separating domain logic, data persistence, and presentation, featuring background audio playback via ExoPlayer and a comprehensive data layer with local and remote sources. The app supports infinite scrolling, custom UI animations, and uses RxJava for asynchronous operations.

The app now supports background audio playback via a new playback layer. This introduces a dual-engine playback system: a standard MediaPlayer for older Android versions and Google ExoPlayer for Lollipop and above, managed by a central PlaybackManager. The service integrates with Android's MediaSession and MediaBrowserService to handle play, pause, skip, and notification updates, while also managing audio focus and Wi-Fi locks to ensure uninterrupted listening.

The data layer is established with a new local data source backed by an SQLite database (MusicDatabaseHelper) and a remote data source for network calls. This includes a suite of mappers (Comment, MiniUser, Playlist, Track, User, UserDetails, WebProfile) to convert between domain models and network/local entities, along with utility classes for data transformation. Repositories (MusicRepository, MusicSearchRepository, MusicPersonalRepository) are introduced to orchestrate data fetching, caching (via ExpiringMap), and local storage, exposing clean interfaces for the domain and presentation layers.

The domain layer is established with a new package structure, including model classes for User, Track, Playlist, and related entities. This change introduces core use cases (interactors) for fetching and modifying user data, such as GetPlaylist, GetTrack, and GetUserFavorites. It also adds a new Playback interface and QueueManager to manage audio playback state and queue navigation. Additionally, repository interfaces are defined for data access, and a base scheduler provider is introduced to handle threading for RxJava operations.

Added four new classes to the UI layer to support enhanced visual effects and list interactions. The app now includes a custom Android Transition (LiftOff) that animates view elevation, a wrapper (PauseLessAnimator) to manage animator listeners without affecting pause/resume states, a RecyclerView scroll listener (OnReachBottomListener) to detect when the user reaches the bottom of a list for infinite scrolling, and a Transition (StartAnimatable) that triggers Animatable drawables on ImageViews.

The Gradle wrapper has been upgraded from version 3.3 to 4.1, ensuring the project uses a more recent version of the Gradle build tool.

Added unit tests for the data layer, including a FakeDataProvider for generating test data, and specific test cases for the CacheStore, TrackMapper, and UserMapper to verify their mapping and caching behaviors.

The project is restructured into separate 'app', 'data', and 'domain' modules, each with their own build configuration. The build system is upgraded to Gradle plugin 3.0.0-beta5 and Kotlin 1.1.4-3, introducing centralized dependency management via a new 'dependencies.gradle' file. This change also updates the minimum supported Android version to API 21 (previously 16) and adds support libraries and testing dependencies for the new modules.
