How to play sounds on Xamarin.forms?

Question

I'm creating an app for Android, iOS and Windows Phone using Xamarin.forms. My question is how to play a mp3 or wav with Xamarin Forms?

My business logic is handled by Shared Project and I don't know how to use platform specifically "MediaPlayer".

Solution 1

I just finished creating an AudioManager for Xamarin that works on iOS, Android, UWP, Windows 8.1, and Windows Phone 8.1. If you are interested check it out at https://github.com/jcphlux/XamarinAudioManager. There is a link to a Nuget package or feel free to clone the project.

Right now Xamarin.forms has not sound API, so you need to use DependencyService

Check the following link, it is working fine for me:

We would require to create an Interface which will be implemented in platform specific project, I named it as IAudio.cs and the code for the same is as follows:

using System;
  namespace AudioPlayEx
   {
    public interface IAudio
        {
            void PlayAudioFile(string fileName);
        }
   }

Android Solution:

    using System;
    using Xamarin.Forms;
    using AudioPlayEx.Droid;
    using Android.Media;
    using Android.Content.Res;

    [assembly: Dependency(typeof(AudioService))]
    namespace AudioPlayEx.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(fileName);
                player.Prepared += (s, e) =>
                {
                    player.Start();
                };
                player.SetDataSource(fd.FileDescriptor,fd.StartOffset,fd.Length);
                player.Prepare();
            }
        }
}

iOS Solution:

using System;
using Xamarin.Forms;
using AudioPlayEx;
using AudioPlayEx.iOS;
using System.IO;
using Foundation;
using AVFoundation;

[assembly: Dependency (typeof (AudioService))]
namespace AudioPlayEx.iOS
{
    public class AudioService : IAudio
    {
        public AudioService ()
        {
        }

        public void PlayAudioFile(string fileName)
        {
            string sFilePath = NSBundle.MainBundle.PathForResource
            (Path.GetFileNameWithoutExtension(fileName), Path.GetExtension(fileName));
            var url = NSUrl.FromString (sFilePath);
            var _player = AVAudioPlayer.FromUrl(url);
            _player.FinishedPlaying += (object sender, AVStatusEventArgs e) => {
                _player = null;
            };
            _player.Play();
        }
    }
}

And finally, we will use the following code in our PCL/shared project in order to play the audio file.

DependencyService.Get<IAudio>().PlayAudioFile("MySong.mp3");

You might give Xam.Plugin.SimpleAudioPlayer a try, since Xamarin.Forms doesn't have a sound API.

In short, add the NuGet package to each platform-specific project you wish to support. Copy the audio files to the Assets folder for Windows UWP and Android and set the build actions as Content and Android Asset respectively. For iOS copy the audio files to the Resources folder and set the build action to BundleResource, then play the files like so:

var player = Plugin.SimpleAudioPlayer.CrossSimpleAudioPlayer.Current; 
player.Load("intro_sound.mp3");
player.Play();

Solution 4

I think, Xamarin.Forms has no sound APIs at the moment so you will have to write custom, platform-specific code.
