Android : Issue having multiple sounds

[Bebz0r]

Hi there,

First, thanks a lot about your fantastic work, @thudugala, the functionnality and usage is really simple and straightforward.

However, I can't make multiple sounds to work on Android. One works fine, but if I want to add more, it does not work : only the first one I declare in .AddAndroid is played :

My files (legit_01.mp3 and legit_02.mp3) are located in Platforms/Android/Resources/raw

I did some tests (uninstalling / reinstalling the app before each test).

Here is how I call my notification. I want to be able to change the sound just by changing "legit_01" to "legit_02" :

// Create the request itself
var request = new NotificationRequest
{
	NotificationId = Convert.ToInt32(NotificationId),
	Title = $"{theNotif.Description} coming at {theNotif.TimeEvent:HH:mm}",
	Subtitle = "", // Appear on the right side of the title (optionnal)
	Description = theNotif.Category,
	// CategoryType, defined in MauiProgram.cs' config is the list of buttons available for actions
	CategoryType = NotificationCategoryType.Status,
	Sound = DeviceInfo.Platform == DevicePlatform.Android ? "legit_01" : "legit_01.mp3", // or legit_02
	Schedule = new NotificationRequestSchedule
	{
		// Set it based on the week day
		NotifyTime = TargetDate,
		RepeatType = NotificationRepeat.TimeInterval,
		NotifyRepeatInterval = TimeSpan.FromDays(7)
	}
};
LocalNotificationCenter.Current.Show(request);

And how I create my two channels :

.UseLocalNotification(config =>
{
	config.AddCategory(new NotificationCategory(NotificationCategoryType.Status)
	{
		ActionList = new HashSet<NotificationAction>(new List<NotificationAction>()
				{
					new NotificationAction(1337)
					{
						Title = "MUTE",
						Android = { LaunchAppWhenTapped = true }
					}
				})
	})
	.AddAndroid(android =>
	{
		android.AddChannel(new NotificationChannelRequest { Sound = "legit_01" });
		android.AddChannel(new NotificationChannelRequest { Sound = "legit_02" });
	});
})

After multiple tests, it's always the first one defined in .AddAndroid that is played, whatever the value of the "Sound" parameter I give to the NotificationRequest. If I switch the AddChannel (e.g. : legit_02 first), it will play legit_02 first, no matter which legit_XX I put in the "Sound" parameter. If I give a random "Sound" parameter though, no sound is played - as if it didn't find the file (which is correct and expected).

Based on the docs, I tried to add Id and Names to the Channels, like so :

.UseLocalNotification(config =>
{
	config.AddCategory(new NotificationCategory(NotificationCategoryType.Status)
	{
		ActionList = new HashSet<NotificationAction>(new List<NotificationAction>()
				{
					new NotificationAction(1337)
					{
						Title = "MUTE",
						Android = { LaunchAppWhenTapped = true }
					}
				})
	})
	.AddAndroid(android =>
	{
		android.AddChannel(new NotificationChannelRequest { Id=$"legit_01", Name="legit_01", Description="legit_01", Sound = "legit_01" });
		android.AddChannel(new NotificationChannelRequest { Id=$"legit_02", Name="legit_02", Description="legit_02", Sound = "legit_02" });
	});
})

But this behaves even worse : the default sound of my device (which is already a custom one) is played.

@Bebz0r Can you please attach a sample project?

[Bebz0r]

Sure, let me create one from scratch, I'll keep you posted

[Bebz0r]

Here you go, I created a sample project reproducing the issue : https://github.com/Bebz0r/TestSoundNotification

By the way, from my tests, it seems that (at least on Android), the mp3 files :

• Have to respect Android naming convention (everything in lowercase letters)
• Must be 128kps (320kps didn't played)
  This could be a nice addition to the read me

@Bebz0r Is your issue fixed after fixing bit rate and name of the file ?

Documentation updated

[Bebz0r]

Hi @thudugala ,
No, the issue still happens, my remark was just a random finding :) Thanks for updating the docs.

@Bebz0r Have you specified the ChannelId in NotificationRequest?

Hi,
I have the same problem with multiple audio files. Only the first file works.

@pelka-mariusz can you please attach a sample project?

Hi,
MauiApp1.zip

An example project is attached. Not any sound is played. Tested on Pixel 5 emulator - API 34 (Android 14.0 - API 34).

Hi,

did you manage to solve the problem?
