Recurring notification is not working

[erossini]

In my NET8 MAUI, I'm using the plugin Plugin.LocalNotification. I set a notification to be repeated daily with this code:

INotificationService _notificationService;

var notifyDateTime = 
    DateTime.Parse($"{DateTime.Now.ToShortDateString()} 08:00:00");
var notification = new NotificationRequest
{
    NotificationId = 100,
    Title = AppResources.NotificationsTitle,
    Description = AppResources.NotificationDescription,
    CategoryType = NotificationCategoryType.Status,
    Schedule =
    {
        NotifyTime = notifyDateTime,
        RepeatType = NotificationRepeat.Daily
    }
};

await _notificationService.Show(notification);

The notification is fired once and then nothing. I thought the notification would stay there until the cancellation and fired daily. Do I have to resend the notification again every time it is fired?

I added in the MauiProgram.cs the following lines

var builder = MauiApp.CreateBuilder();
builder
	.UseMauiApp<App>()
	.........
	.UseLocalNotification();

For the other settings, I followed the documentation. In the AndroidManifest.xml I added the following lines

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM" />
<uses-permission android:name="android.permission.USE_EXACT_ALARM" />

The issue I had was with the Google Play. When I submitted the app with those settings, Google rejected my app because it is not an agenda or a calendar.

I just want to give you an update. The notification is working perfectly on iOS. On Android defo it is not working and on some devices the app crashes.

Hi, I have a Samsung Galaxy S20. I followed all the procedures mentioned in the link https://github.com/thudugala/Plugin.LocalNotification/wiki/3.-Scheduled-Android-notifications
I'm creating daily notifications starting in 3 days but the notification doesn't arrive.
If I create it to notify every 1 day, it works.
Does anyone have any tips?

You forgot to add the following line to the AndroidManifest.xml:
<uses-permission android:name="android.permission.WAKE_LOCK" />

You forgot to add the following line to the AndroidManifest.xml: <uses-permission android:name="android.permission.WAKE_LOCK" />

I used it and others but the error persists:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />

<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.USE_EXACT_ALARM" />
<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM" android:maxSdkVersion="32" />

Same here on iOS. When I schedule for daily or even use a 24 hour TimeSpan, it doesn't fire the next day. When I iterate the pending notifications it does see one for the right day and time, though now it's in the past. The weird thing is that when I set it to repeat every minute with a cancel date it seems to work. I'm running the app in the background during my tests.

I use LocalNotificationCenter.Current, not INotificationService, and it works correctly

I ended up writing my own code. I'm using AlarmManager to get the notification to be as accurate as possible, along with a BroadcastReceiver and a BootReceiver. When it sends the daily notification, and schedule the next one. And this all happens whether the app is in the background or not. It works well for my use case.

The thing that made it complicated was that in .NET 9 Maui (perhaps earlier versions too?) you don't need to put the receiver references in the manifest like all the docs tell you to do.

Can you send code?
