I am trying to integrate my .NET MAUI app with Azure cognitive speech service, following the old xamarin tutorial from microsoft https://learn.microsoft.com/en-us/xamarin/xamarin-forms/data-cloud/azure-cognitive-services/speech-recognition
According to this guy MAUI-Android: How to keep Google Speech Recognizer from timeout it should work.
The implementation part of the microphone service is giving me compilation errors. This is the code:
using Android.App;
using Android.Content.PM;
using Android.OS;
using AndroidX.Core.App;
using Google.Android.Material.Snackbar;
using System.Threading.Tasks;
using Atk.Progen.NETMAUI.Interfaces;
using Atk.Progen.NETMAUI.Platforms.Android;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Android;
namespace Atk.Progen.NETMAUI.Platforms.Android
{
public class MicrophoneService
{
public const int RecordAudioPermissionCode = 1;
private TaskCompletionSource<bool> tcsPermissions;
string[] permissions = new string[] { Manifest.Permission.RecordAudio };
public MicrophoneService()
{
tcsPermissions = new TaskCompletionSource<bool>();
}
public Task<bool> GetPermissionAsync()
{
if ((int)Build.VERSION.SdkInt < 23)
{
tcsPermissions.TrySetResult(true);
}
else
{
var currentActivity = MainActivity.Instance;
if (ActivityCompat.CheckSelfPermission(currentActivity, Manifest.Permission.RecordAudio) != (int)Permission.Granted)
{
RequestMicPermissions();
}
else
{
tcsPermissions.TrySetResult(true);
}
}
return tcsPermissions.Task;
}
public void OnRequestPermissionResult(bool isGranted)
{
tcsPermissions.TrySetResult(isGranted);
}
void RequestMicPermissions()
{
if (ActivityCompat.ShouldShowRequestPermissionRationale(MainActivity.Instance, Manifest.Permission.RecordAudio))
{
Snackbar.Make(MainActivity.Instance.FindViewById(Android.Resource.Id.Content),
"Microphone permissions are required for speech transcription!",
Snackbar.LengthIndefinite)
.SetAction("Ok", v =>
{
((Activity)MainActivity.Instance).RequestPermissions(permissions, RecordAudioPermissionCode);
})
.Show();
}
else
{
ActivityCompat.RequestPermissions((Activity)MainActivity.Instance, permissions, RecordAudioPermissionCode);
}
}
}
}
The error is on MainActivity.Istance and on Android.Resource.Id.Content. It says "MainActivity does not contain definition for Instance".
Any suggestion on how to make it work on .net MAUI?
