MauiAudio-Cross platform audio plugin for MAUI

Based from .NET Podcasts - Sample Application

Intro

Platform/Android

AndroidManifest.xml

<uses-permission android:name="android.permission.WAKE_LOCK" />

MainActivity.cs

using Android.Content;
using MauiAudio.Platforms.Android;
using MauiAudio.Platforms.Android.CurrentActivity;

public class MainActivity : MauiAppCompatActivity,IAudioActivity
{
    MediaPlayerServiceConnection mediaPlayerServiceConnection;

    public MediaPlayerServiceBinder Binder { get; set; }

    public event StatusChangedEventHandler StatusChanged;
    public event CoverReloadedEventHandler CoverReloaded;
    public event PlayingEventHandler Playing;
    public event BufferingEventHandler Buffering;

    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        CrossCurrentActivity.Current.Init(this, savedInstanceState);
        NotificationHelper.CreateNotificationChannel(ApplicationContext);
        if (mediaPlayerServiceConnection == null)
            InitializeMedia();
    }

    private void InitializeMedia()
    {
        mediaPlayerServiceConnection = new MediaPlayerServiceConnection(this);
        var mediaPlayerServiceIntent = new Intent(ApplicationContext, typeof(MediaPlayerService));
        BindService(mediaPlayerServiceIntent, mediaPlayerServiceConnection, Bind.AutoCreate);
    }
}

Usage

private readonly INativeAudioService audioService;
public async Task PlayAsync(string url)
    {
        await audioService.InitializeAsync(url);
        await audioService.PlayAsync(position);
    }

or use MediaPlay:

private readonly INativeAudioService audioService;
public class MediaPlay
    {
        public string Name { get; set; }
        public string Author { get; set; }
        public string URL { get; set; } # URL is must
        public string Image { get; set; }
    }

MediaPlay media=new(){...};
await audioService.InitializeAsync(media);
# play 
# position is double (second)
await InternalPlayAsync(position);
# pause
await audioService.PauseAsync();

Interface

Version ≥ 1.0.6

public interface INativeAudioService
{
    Task InitializeAsync(string audioURI);
    Task InitializeAsync(MediaPlay media);
    Task PlayAsync(double position = 0);

    Task PauseAsync();
    ///<Summary>
    /// Set the current playback position (in seconds).
    ///</Summary>
    Task SetCurrentTime(double value);

    Task DisposeAsync();
    ///<Summary>
    /// Gets a value indicating whether the currently loaded audio file is playing.
    ///</Summary>
    bool IsPlaying { get; }
    ///<Summary>
    /// Gets the current position of audio playback in seconds.
    ///</Summary>
    double CurrentPosition { get; }
    ///<Summary>
    /// Gets the length of audio in seconds.
    ///</Summary>
    double Duration { get; }
    ///<Summary>
    /// Gets or sets the playback volume 0 to 1 where 0 is no-sound and 1 is full volume.
    ///</Summary>
    double Volume { get; set; }
    /// <summary>
    /// Gets or sets the playback volume muted. false means not mute; true means mute.
    /// </summary>
    bool Muted { get; set; }

    ///<Summary>
    /// Gets or sets the balance left/right: -1 is 100% left : 0% right, 1 is 100% right : 0% left, 0 is equal volume left/right.
    ///</Summary>
    double Balance { get; set; }

    event EventHandler<bool> IsPlayingChanged;
    event EventHandler PlayEnded;
    event EventHandler PlayNext;
    event EventHandler PlayPrevious;
}

version<1.0.6

public interface INativeAudioService
{
    Task InitializeAsync(string audioURI);
    Task InitializeAsync(MediaPlay media);
    Task PlayAsync(double position = 0);

    Task PauseAsync();

    Task SetMuted(bool value);

    Task SetVolume(int value);

    Task SetCurrentTime(double value);

    ValueTask DisposeAsync();

    bool IsPlaying { get; }

    double CurrentPosition { get; }
    double Duration { get; }

    event EventHandler<bool> IsPlayingChanged;
    event EventHandler PlayEnded;
    event EventHandler PlayNext;
    event EventHandler PlayPrevious;
}

Notify

If you want to process the player's previous or next song:(only Android and Windows available now), preprocess the four EventHandlers.

    event EventHandler<bool> IsPlayingChanged;
    event EventHandler PlayEnded;
    event EventHandler PlayNext;
    event EventHandler PlayPrevious;
