import { TNSPlayer } from 'nativescript-audio';

export class YourClass {
private _player: TNSPlayer;

constructor() {
this._player = new TNSPlayer();
this._player.debug = true; // set true to enable TNSPlayer console logs for debugging.
this._player
.initFromFile({
audioFile: '~/audio/song.mp3', // ~ = app directory
loop: false,
completeCallback: this._trackComplete.bind(this),
errorCallback: this._trackError.bind(this)
})
.then(() => {
this._player.getAudioTrackDuration().then(duration => {
// iOS: duration is in seconds
// Android: duration is in milliseconds
console.log(`song duration:`, duration);
});
});
}

public togglePlay() {
if (this._player.isAudioPlaying()) {
this._player.pause();
} else {
this._player.play();
}
}

private _trackComplete(args: any) {
console.log('reference back to player:', args.player);
// iOS only: flag indicating if completed succesfully
console.log('whether song play completed successfully:', args.flag);
}

private _trackError(args: any) {
console.log('reference back to player:', args.player);
