"PendingIntent must be mutable" error using Geofencing

[RQISystems]

I have created a .NET MAUI 10 App that uses geofencing to allow users to verify if a location is valid and to add reviews using Actions. When I add .UseLocalNotificationGeofence to MauiProgram.cs, I get the following error: "10: PendingIntent must be mutable". If I remove the line from MauiProgram, i do not get the error. Here is the JavaException:

"com.google.android.gms.common.api.ApiException: 10: PendingIntent must be mutable

I am creating the NotificationRequests based on a collection of Locations that the user has requested. Here is my MauiProgram.cs code:

.UseLocalNotification(config =>
{
config.AddCategory(new NotificationCategory(NotificationCategoryType.Status)
{
ActionList =
[
new(100)
{
Title = "Yes",
Android =
{
LaunchAppWhenTapped = false,
IconName =
{
ResourceName = "launcher_40"
}
},
Apple =
{
Action = Plugin.LocalNotification.Core.Models.AppleOption.AppleActionType.Foreground
}
},
new(101)
{
Title = "No",
Android =
{
LaunchAppWhenTapped = false,
IconName =
{
ResourceName = "launcher_40"
}
},
Apple =
{
Action = Plugin.LocalNotification.Core.Models.AppleOption.AppleActionType.Foreground
}
},
new(102)
{
Title = "Add Review",
Android =
{
IconName = { ResourceName = "add.png" },
LaunchAppWhenTapped = true
},
Apple =
{
Action = Plugin.LocalNotification.Core.Models.AppleOption.AppleActionType.Foreground
}
}
]
})
.AddAndroid(android =>
{
android.AddChannel(new AndroidNotificationChannelRequest
{
Id = "",
Name = "",
Description = "",
Importance = AndroidImportance.High,
Sound = "rimshot"
});
})
.AddiOS(iOS =>
{
#if IOS
//iOS.SetCustomUserNotificationCenterDelegate(new CustomUserNotificationCenterDelegate());
#endif
});
})
.UseLocalNotificationGeofence();

My NotificationRequest code is:
var notification = new NotificationRequest
{
NotificationId = Convert.ToInt32(sight.SightInGeofence.Id),
Image = { ResourceName = "launcher_40" },
Title = "Sight Nearby!",
Subtitle = "Is the Sight still there?",
Description = "Click the Add Review button.",
CategoryType = NotificationCategoryType.Status,
Android =
{
ChannelId = "",
Priority = AndroidPriority.High,
TimeoutAfter = TimeSpan.FromHours(1),
OnlyAlertOnce = true,
IconSmallName = { ResourceName = "launcher_40" },
IconLargeName = { ResourceName = "launcher_40" },
},
Apple =
{
ShowInNotificationCenter = true,
}
};

notification.Geofence = new NotificationRequestGeofence
{
Center = new NotificationRequestGeofence.Position
{
Latitude = Convert.ToDouble(sight.SightInGeofence.Location_Latitude),
Longitude = Convert.ToDouble(sight.SightInGeofence.Location_Longitude),
},
RadiusInMeters = 30,
NotifyOn = NotificationRequestGeofence.GeofenceNotifyOn.OnEntry | NotificationRequestGeofence.GeofenceNotifyOn.OnExit,
};

Also, my notifications are not showing the Action buttons. I assume it is related to the issue above.

Thanks in advance for your help.

Can you please attach a sample project?

I'm using the Sample project for Maui from the github repository. I have modified the code with the code above. I have updated the Microsoft.Maui.Controls package to 10.0.80. I get the error in the following code block:

try
{
if (await _notificationService.AreNotificationsEnabled() == false)
{
await _notificationService.RequestNotificationPermission();
}

var status = await Permissions.RequestAsync<Permissions.LocationWhenInUse>();
if (status == PermissionStatus.Granted)
{
    var ff = await _notificationService.Show(request);
}

//var ff = await _notificationService.Show(request);

}
catch (Exception exception)
{
Console.WriteLine(exception);
}

The error has changed to: "exception {"1000:"} and the JavaStackTrace is as follows:

exception.StatusCode == 1000 is Android reporting GEOFENCE_NOT_AVAILABLE.

On the emulator, use a Google Play system image, turn Location on, and set a simulated location in Extended Controls before creating the geofence.

If 1000 still happens after a restart, check these emulator steps:

1. In the emulator, open Maps once and confirm it can get a blue-dot location.
2. In the emulator Extended Controls > Location, send a location.
3. In Android Settings > Location, ensure Location is On.
4. In App Info > Permissions > Location, set “Allow all the time."
5. Use a radius of at least 100m.
6. Cold boot the emulator from Device Manager if Play Services remains stuck.
