KotlinAudio is an Android audio player written in Kotlin, making it simpler to work with audio playback from streams and files.
Inspired by SwiftAudioEx. Our aim is to have feature parity with the iOS equivalent.

implementation 'com.github.doublesymmetry:kotlinaudio:v2.0.0'To get started playing some audio:
let player = AudioPlayer()
let audioItem = DefaultAudioItem(audioUrl: "someUrl", type: MediaType.DEFAULT)
player.load(item: audioItem, playWhenReady: true) // Load the item and start playing when the player is ready.To listen for events in the AudioPlayer, subscribe to events found in the event property of the AudioPlayer.
To subscribe to an event:
// jetpack compose
val state = player.event.stateChange.collectAsState(initial = AudioPlayerState.IDLE)
// normal
player.event.stateChange.collect {}The QueuedAudioPlayer is a subclass of AudioPlayer that maintains a queue of audio tracks.
let player = QueuedAudioPlayer()
let audioItem = DefaultAudioItem(audioUrl: "someUrl", type: MediaType.DEFAULT)
player.add(item: audioItem, playWhenReady: true) // Since this is the first item, we can supply playWhenReady: true to immedietaly start playing when the item is loaded.When a track is done playing, the player will load the next track and update the queue.
All AudioItems are stored in either previousItems or nextItems, which refers to items that come prior to the currentItem and after, respectively. The queue is navigated with:
player.next() // Increments the queue, and loads the next item.
player.previous() // Decrements the queue, and loads the previous item.
player.jumpToItem(index:) // Jumps to a certain item and loads that item. player.remove(index:) // Remove a specific item from the queue.
player.removeUpcomingItems() // Remove all items in nextItems.KotinAudio is available under the MIT license. See the LICENSE file for more info.
