Question

I have the iOS application developed in the Xamarin.Forms. How can I play the sound when app is in minimized mode?

Could someone please give any hint or example of how to do it?

Thanks in advance.

class musicPlayer {
    public static var instance = musicPlayer()
    var player = AVPlayer()

    func initPlayer(url : String) {
        guard let url = URL.init(string: url) else { return }
        let playerItem = AVPlayerItem.init(url: url)
        player = AVPlayer.init(playerItem: playerItem)
        playAudioBackground()
    }

    func playAudioBackground() {
        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, mode: AVAudioSessionModeDefault, options: [.mixWithOthers, .allowAirPlay])
            print("Playback OK")
            try AVAudioSession.sharedInstance().setActive(true)
            print("Session is Active")
        } catch {
            print(error)
        }
    }

    func pause(){
        player.pause()
    }

    func play() {
        player.play()
    }
}
