How to play a track and listen to events

Prerequisites

• Package installed and Expo dev build setup completed.
• Native host app running (expo run:ios or expo run:android).

Steps

1. Call setup before playback operations.

await audioPlayer.setup();

2. Register listeners.

const progressHandle = onPlaybackProgress(({ position }) => {
  console.log('position', position);
});
const stateHandle = onPlaybackStateChanged(({ state }) => {
  console.log('state', state);
});

3. Add a track to queue.

await audioPlayer.add({
  tracks: [{ id: 'intro', url: 'https://example.com/intro.mp3' }],
  startIndex: 0,
});

4. Start playback.

await audioPlayer.play();

5. Remove listeners during teardown.

await progressHandle.remove();
await stateHandle.remove();

Expected Result

Playback and event delivery are app-wired from runtime namespaces (audioPlayer, listener helpers), with explicit listener cleanup.
