Breeze

A modern music-playing app, built using Modern-Architectural practices.

How to build the app

• clone the repo
• open the app in android studio
• run the application

What is used in this app

• ExoPlayer (The Heart of this App)
• Coil - For Image Loading
• Mockito-Kotlin - Testing
• Koin - For Dependency Injection
• MVVM

Structure

The project is divided into two parts :

1. Player
2. App

Player

As the name suggests, the Player part is responsible for handling all the events:

1. Play/Pause the Music
2. Handle user input from Notification Bar
3. Manages Next/Previous

App

This is the part of the application, that manages the overall performance of the application. The structure of this applilcation:

- data
   -- model
      - Song
   -- repository
      - PlaylistRepositoryImp
   -- source
      - dao
        - SongDao
      - AppDatabase

The above structure forms the lowest level of the architecture for Breeze. This is the level, where a song is stored and all modification(Insertion of a song/ Deletion of a song/Retriveal of song) happens.

To store a song, a 'Song' Entity is created(aka Table), with the following schema:

data class Song(
    @PrimaryKey var id: Int,
    var songName: String?,
    var path: String,
    var artistName: String?,
    var albumArt: String?,
    var duration: String?,
    var type: Int = 0
) : ASong(id, songName, albumArt, artistName, path, type, duration), Parcelable

The following operations can be performed on the Song entity using SongDao :

@Insert(onConflict = OnConflictStrategy.REPLACE)
fun insert(song: Song): Long

@Query("SELECT * FROM Song")
fun loadAll(): MutableList<Song>

@Delete
fun delete(song: Song)

@Query("DELETE FROM Song")
fun deleteAll()

@Query("SELECT * FROM Song where id = :songId")
fun loadOneBySongId(songId: Long): Song?

@Query("SELECT * FROM Song where title = :songTitle")
fun loadOneBySongTitle(songTitle: String): Song?

@Update
fun update(song: Song)

In this project, Koin is used for dependecny injection.
