How do I solve this problem to play sound or music using Simple Audio player?

CodePudding user response：

this is a basic C# error. You are declaring a local variable inside a method, then trying to use it in another method. If you want to reference an object from multiple methods, you have to declare it at the class level so it remains in scope.

    // declare this at the class level so it remains in scope
    ISimpleAudioPlayer simpleAudioPlayer

    public MainPage()
    {
        InitializeComponent();
        
        simpleAudioPlayer = CrossSimpleAudioPlayer.CreateSimpleAudioPlayer();;

It looks like you are trying to use the Simple Audio Player package in Xamarin.Forms project, but it is only compatible with .NET Framework projects. This is why you are seeing the error message "Package Xam.Plugin.SimpleAudioPlayer.WPF 1.6.0 is not compatible with monoandroid13.0 (MonoAndroid, Version=v13.0)".

To play audio in a Xamarin.Forms projects, you can use Xamarin.Essentials MediaPlayer class. This class provides a simple API for playing audio files on iOS, Android, and UWP.

Here's an example of how you can use it to play an audio file in your MainPage class:

public MainPage()
{
    InitializeComponent();
    // Replace "Beep.mp3" with the name of your audio file
    string fileName = "Beep.mp3";
    // Load the audio file as a stream
    var assembly = typeof(MainPage).GetTypeInfo().Assembly;
    Stream stream = assembly.GetManifestResourceStream($"{assembly.GetName().Name}.{fileName}");
    // Play the audio file
    MediaPlayer.Play(stream);
}

Note that you need to include the audio file as an embedded resource in your project. You can do this by right-clicking on the file in the Solution Explorer, selecting "Properties", and setting the "Build Action" to "Embedded Resource".
