Android: Tapping a notification causes second `OnCreate()` call and crash.

[RobTF]

Description

I start with an application which generates a notification. I opted to use a foreground service to generate the notification however it doesn't seem to make a difference how the notification is generated.

The notification in the foregroun service is created like so;

                var notification = new NotificationCompat.Builder(this, "MyChannel")
                .SetContentTitle("Notification Title")
                .SetContentText("Notification Description")
                .SetSmallIcon(Resource.Drawable.DefaultNotificationIcon)
                .SetContentIntent(pendingIntent)
                .SetOngoing(true)
                .SetShowWhen(false)
                .Build();

                StartForeground(10000, notification);

I start the service in the OnCreate lifecycle callback, which results in an app with the notification present;

When the user taps on the notification two things happen;

1l The OnCreate lifecycle activity is called again for the same activity instance it got called for on startup. There is no call on OnDestroy.

2. The app crashes with the following error

Steps to Reproduce

1. Open my reproduction project.
2. Build and run on Android (real device or simulator)
3. When the app launches wait for the notification to appear, and tap it.
4. Observe crash.

I think putting [Android.App.Activity(LaunchMode = Android.Content.PM.SingleTask)] or [Android.App.Activity(LaunchMode = Android.Content.PM.SingleInstance)] on MauiAppCompatActivity would solve the problem but is that what MAUI wants to do for ALL apps?

[RobTF]

[Android.App.Activity(LaunchMode = Android.Content.PM.SingleTask)]

Thanks @AmrAlSayed0 - unfortunately this still fails in exactly the same way if the user taps the notification and the activity is in the foreground already, but does fix the issue of tapping when the activity is in the background.

EDIT: To clarify, when I say "this" doesn't work, I mean either of the proposed values for LaunchMode as I tested both.

[henda79]

Same issue here, I'm using Notifications from the Shiny.org lib

[ne0rrmatrix]

I am having same issue. Anyone have a workaround for this?

[masterofdaemon]

Me too

Changing to LaunchMode = Android.Content.PM.SingleTask) fixed it for me. But I would like to see at least a way forward that does not require this adjustment.

This only works if killing the activity kills the app process as essentially when you tap the notification you're getting a totally fresh copy of your app. If you run foreground services etc. unfortunately, it has no effect and the crash still occurs as your app has an existing process running.

Verified this on Visual Studio Enterprise 17.7.0 Preview 2.0. Repro on Android 13.0-API33 with below Project: NotificationTapIssue.zip

[sfernandez131]

Still a problem.

[sfernandez131]

It appears to be crashing somewhere in the base.OnStart() method. I can't figure out how to debug or at least see what's going on.

[ibanezjp]

Still a big issue. We are using .NET 8 and this is preventing us from releasing a version. Any update?

[AlleSchonWeg]

Hi, in this video: https://youtu.be/YNkdsJTyOJE?t=64 the author has the same exception and show how to fix it.

[RobTF]

Unfortunately, the solution in the video doesn't work if you kill the activity via a "swipe up" but the app contains background processing such as a foreground service (see my note above).

The problem remains and cannot be worked around by adjusting the activity type.

Solución:

[hugofonseca-incontrol]

Solución:

@edwinjoelmarte could you please provide more detail regarding where and when in the lifecycle of the app are you doing this exactly to overcome the issue?

[sfernandez131]

That's assigned to the intent that's captured in the notification.

[konradzuse]

This is a problem for me also, using Shiny.Notifications library
