How to access microphone in Xamarin emulator - xamarin

Question

Is it possible or is there anyway that I can access the Microphone and use it to test my code?
I have enabled all of this in the extended controls of my emulator for microphone:
I also have these permissions in my AndroidManifest.xml:
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
This is the code:
using System;
using System.ComponentModel;
using Plugin.AudioRecorder;
using Xamarin.Forms;
namespace AudioDemo
{
[DesignTimeVisible(true)]
public partial class MainPage : ContentPage
{
AudioRecorderService recorder;
AudioPlayer player;
public MainPage()
{
InitializeComponent();
recorder = new AudioRecorderService
{
StopRecordingAfterTimeout = true,
TotalAudioTimeout = TimeSpan.FromSeconds(15),
AudioSilenceTimeout = TimeSpan.FromSeconds(2)
};
player = new AudioPlayer();
player.FinishedPlaying += Finaliza_Reproducao;
}
async void Record_Clicked(object sender, EventArgs e)
{
try
{
if (!recorder.IsRecording)
{
recorder.StopRecordingOnSilence = TimeoutSwitch.IsToggled;
RecordButton.IsEnabled = false;
PlayButton.IsEnabled = false;
//Start recording
var audioRecordTask = await recorder.StartRecording();
RecordButton.Text = "Parar Gravação";
RecordButton.IsEnabled = true;
await audioRecordTask;
RecordButton.Text = "Record";
PlayButton.IsEnabled = true;
}
else
{
RecordButton.IsEnabled = false;
//stop recording ...
await recorder.StopRecording();
RecordButton.IsEnabled = true;
}
}
catch (Exception ex)
{
//blow up the app!
await DisplayAlert("Erro", ex.Message, "OK");
}
}
async void Play_Clicked(object sender, EventArgs e)
{
try
{
var filePath = recorder.GetAudioFilePath();
if (filePath != null)
{
PlayButton.IsEnabled = false;
RecordButton.IsEnabled = false;
player.Play(filePath);
}
}
catch (Exception ex)
{
//blow up the app!
await DisplayAlert("Error", ex.Message, "OK");
}
}
void Finaliza_Reproducao(object sender, EventArgs e)
{
PlayButton.IsEnabled = true;
RecordButton.IsEnabled = true;
}
}
}
This code works when I use a phone to run it, but when I just use (my laptop) emulator, it does not work.

Not able to record sound in the emulator because the android emulator doesn’t support it yet. This code should only work on the phone.
Note: The Android Emulator cannot record audio. Be sure to test your
code on a real device that can record.
