How to sound (beep)? - Xamarin Forms

Question

I need to sound (beep) on the Smartphone to get the user’s attention, I’m testing only by a button initially. The codes I have tested only gives error, the last is being link here. What I did I understood is below:

   //Botão Som
        private void Som_Clicked(object sender, EventArgs e)
        {
            var player = Plugin.SimpleAudioPlayer.CrossSimpleAudioPlayer.Current;
            player.Load("Glass_audio.mp3");

            player.Play();
            Task.Delay(10000);
        }

The mistake:

Answer 1

In the System.Media namespace has a class called Systemsounds, which contains methods to perform the main sounds associated with Windows (Beep, Asterisk, Question, Exclamation and Hand).

So just use this class to play the sound you want.

using System.Media;

public class MinhaClasse
{
public void TocarBeep()
{
    // Toca o som associado ao Beep, no Windows
    SystemSounds.Beep.Play();
}
}

There may be error caused by the version of the OS used. In this case something more specific should be used.

Answer 2

The beep function is not compatible with Android platform.

To run a warning sound on Android follow this guide.
