How to play audio continuously in xamarin forms - xamarin

Question

I implemented audio implementation and added looping property also. But the audio Plays a two times only and after that audio doesn't play. Here I attached a code I implemented. Kindly help how to fix. Thanks for advance
namespace Com.Audio.Droid
{
public class AudioService : IAudio
{
public AudioService()
{
}
public void PlayAudioFile(string fileName)
{
var player = new MediaPlayer();
var fd = global::Android.App.Application.Context.Assets.OpenFd("siren.wav");
player.Prepared += (s, e) =>
{
player.Start();
};
player.SetDataSource(fd.FileDescriptor, fd.StartOffset, fd.Length);
player.Looping = true;
player.Prepare();
}
public void PauseAudioFile(string fileName)
{
Device.BeginInvokeOnMainThread(() =>
{
var player = new MediaPlayer();
var fd = global::Android.App.Application.Context.Assets.OpenFd("siren.wav");
player.Prepared += (s, e) =>
{
player.Stop();
player.Release();
player.Dispose();
};
player.SetDataSource(fd.FileDescriptor, fd.StartOffset, fd.Length);
player.Prepare();
});
}
}
}
And in iOS the audio play a only one second. It's doesn't play the audio file entirely
namespace com.Audio.ios
{
public class AudioService : IAudio
{
public AudioService()
{
}
public void PlayAudioFile(string fileName)
{
string sFilePath = NSBundle.MainBundle.PathForResource(Path.GetFileNameWithoutExtension("siren"), Path.GetExtension("siren.wav"));
var url = NSUrl.FromString(sFilePath);
var _player = AVAudioPlayer.FromUrl(url);
_player.FinishedPlaying += (object sender, AVStatusEventArgs e) =>
{
_player = null;
};
_player.NumberOfLoops = -1;
_player.Play();
}
public void PauseAudioFile(string fileName)
{
string sFilePath = NSBundle.MainBundle.PathForResource(Path.GetFileNameWithoutExtension("siren"), Path.GetExtension("siren.wav"));
var url = NSUrl.FromString(sFilePath);
var _player = AVAudioPlayer.FromUrl(url);
_player.FinishedPlaying += (object sender, AVStatusEventArgs e) =>
{
_player = null;
};
_player.Stop();
}
}
}

For Android
You need a hook way to implement a loopMediaPlayer, that is creating a new player when the audio is finished.
Refer to : https://stackoverflow.com/a/29883923/8187800 .
For iOS
Due to ARC , probably AVAudioPlayer is released after calling dependency service , to solved it you can try to make _player as global variable .
