Describe the bug
When you schedule multiple notifications, and they have all been triggered, you will only get the ReturningData from the last notification that was triggered.

To Reproduce
Steps to reproduce the behavior:

1. Schedule one notification in 5 seconds with the Title and ReturningData = "1"
2. Schedule another notification in 10 seconds with the Title and ReturningData = "2"
3. Add a NotificationTapped handler that just prints the Data
4. Run the App
5. Wait for both notifications to appear
6. Click on one notification and see that it says "2" in the console
7. Click on the other notification, it will also say "2" in the console

Expected behavior
When I click on the first notification, I want to get the ReturningData that was scheduled with the first notification and when I click the second notification, I want the ReturningData for that.

Platform:

• OS: Android
• Version: Android 10.0 - API 29

Smartphone:

• Device: Samsung SM-G973F
• OS: Android 10.0
• Version: API 29

Additional context
If you click on the first notification, before the second one appear, you get the correct data for it, and when you wait for the second one, it also has the correct data. The problem only occurs if you wait for both notifications to be shown.

Describe the bug
Plugin.LocalNotification and System.ServiceModel can't be together in the same project

To Reproduce
Steps to reproduce the behavior:
When I include wcf service to my project , the dependence for: System.ServeceModel.Duplex + System.ServeceModel.Http + System.ServeceModel.NetTcp + System.ServeceModel.Security and 73 compile Error popup !!!

Here's the sample project , from this site, with the Compile errors
Sample.zip

Hi,

In the attached sample, Ia m using a PeriodicWorkRequest to be running every 30 minutes and inside the WorkRequest I am getting prayer times and then scheduling the time for the notifications.

I am showing the Times On MainPage,xaml just to refer to..

The problem that when I start the app then the push notification is sent immediately although it should be scheduled on the specific time which gives false alert about the prayer time

Also try to close the app several times and open several times you'll notice the push notification is being sent too

LocalNotifications.zip

I install this plugin to PCL and all project in Xamarin.form without error.
and in Iphone it works well.
But in android I get the following error message.

[Plugin.LocalNotification] No platform plugin found. Did you install the nuget package in your app project as well?"

What did I miss in installation.

Thanks.

Describe the bug
Badge on app is not cleared after reading the local notification

To Reproduce
Steps to reproduce the behavior:

1. Send some local notification.
2. Read it.
3. Badge still hangs on app icon

Expected behavior
Badge should be cleared

Platform (please complete the following information):

• OS: iOS
• Version 10+

When trying to install package from NuGet in VS 2019 16.4.3 I have this error:

Failed to add reference. The package 'Plugin.LocalNotification' tried to add a framework reference to 'System.Drawing.Common.dll' which was not found in the GAC. This is possibly a bug in the package. Please contact the package owners for assistance.
Reference unavailable.

Describe the bug
No sound is played on devices with Android 7.0 or before

It doesn't work if request.Sound is null or empty. It works if request.Sound is set e.g. to "Default". The sound file must not exist.

The documentation is out of date, in the Platform Specific Notes section, NotificationCenter has Current property, has no NotificationIconId, etc.

I've spent a significant amount of time on this: the tap handler does not fire if ReturningData is not set.
Seems to be the case only for iOS.

For example, If I set a notification to pop at 18:30. Is it possible for my app to pop a notification at 18;30, everyday till I disable that particular notification?

Sample

Also, I noticed that on Android Oreo, the icon doesn't get any color (not even the gray when no color is set). Any idea why? I've only been testing on Android 8 and 9.

Check this out:

Android 9 Pie:

Android 8 Oreo:

As I know, this color feature was added on API 21, right? Not sure though.. Also, the icon file is exactly the same on both.

This could be a thing on my physical device.. it's a Samsung A5 2017 with the brand modified Android system and things..

And, by the way, thanks for the plugin, it's pretty good. I've been testing and if everything runs smooth, I'll use it on production.

Describe the bug
You have a typo in code

To Reproduce
https://github.com/thudugala/Plugin.LocalNotification/wiki/How-to-change-notification-icon

Expected behavior
IconName = "myicon"

Is the migration to AndroidX planned ?

Describe the bug
The setted icon is only used in notifications when app is running in debug mode or in release mode with linking option set to none.
In that last case, it uses the launcher icon instead of the icon set in the notification options. Also, this only happens when NotifyTime is set to future. I tested it with a past DateTime and it didn't appeared any notification. I believe this is expected behavior. Instant notifications works just fine.

To Reproduce
Steps to reproduce the behavior:

1. Set a notification with an icon and also set a launcher icon on the android project and a future NotifyTime.
2. Set linking option to "SDK Assemblies Only" in release mode.
3. Run app in release mode.
4. Future notifications shows up with the app launcher icon instead of the originally setted icon on code.

IconSample.zip

Expected behavior
Future notification shown with the selected notification icon of when it was setted on code.

☝️ Android 9: blank round icon because android expects a entirely white icon, and that's not the launcher icon case.

☝️ Android 8: actually shows launcher entirelly instead of setted icon on the notification.

Platform (please complete the following information):

• OS: Android
• Target version: 10

Smartphone (please complete the following information):

• Device: Genymotion emulator and Samsung A5 2017
• OS: Android
• Version: 9 and 8 respectively

Additional context
I bet the other issue that I had (#63) is probably happening because of that and I see that #69 may have some similarity as well. The issue at #58 may also have some similarity with this "only works without any linking set" thing and such.

This also is the reason that another project of mine (my main one atm) is actually not showing notifications when NotifyTime is set. I just disabled linking and it's working flawlessly. It soon needs to go into production, so I just gotta deal with the big apk size. If you have any idea of what's going on, it would help a lot.

Thanks for the plugin, see you guys.

Hi

How can I loop through all the scheduled notifications and read their details?

Or how can I get a specific scheduled notification details by ID?

** I a not not talking about Notification_Tapped here but I just want to know what are all the pending notifications

Thanks,
Jassim

Hi,

First of all, thanks and appreciate for the effort of creating this plugin, it is working in anywhere accept no alert sound or ring when notification appears, seeking fo help.

Thank you =)

I installed the nuget package in both Android and iOS projects of Xamarin Forms project.
The NotificationCenter.Current property has a compilation error that it does not exist in the iOS project. I tried changing the iOS deployment target to 11, but still the error exist.

I couldn't show the notification due to this issue.

Refer the attached screenshot.

Hi,

In this link:

https://github.com/thudugala/Plugin.LocalNotification/wiki/Notification-with-a-Sound-File

It's mentioned from Androidn >= 26 the sound must be set in Channel Level

What if I have different sound files and it depends on the user preference the sound should play?

Thanks,
Jassim

Describe the bug
Updated from v4.0.8 to v4.1.1 and now notifications with a NotifyTime set in the future no longer work on Android. Instead the application output displays the following when the time is reached but no notification is displayed:
[WM-WorkerWrapper] Worker result SUCCESS for Work [ id=8b6a975d-8bb3-43c7-9dc8-23110e719443, tags={ md50e8eea8286f69b03ef3779df0abd57a6.ScheduledNotificationWorker, 4 } ]

To Reproduce
Steps to reproduce the behavior:

1. Install v4.1.1 from nuget.
2. Setup notification request on Android for a future time.
3. Wait for notification to reach time.
4. No local notification is displayed.

Expected behavior
A local notification should appear like previous versions.

Screenshots

Platform (please complete the following information):

• OS: Android
• Version: All versions, recently tested on API 29

Smartphone (please complete the following information):

• Device: Pixel 2XL
• OS: Android
• Version: API 29

Additional context

NotificationCenter.Current.NotificationTapped += LoadPageFromNotification is being binded everytime in App constructor, which binds the event multiple times in android.
That can cause of invoking LoadPageFromNotification multiple time on single notification click. I would appreciate if you add some solution for this too in your sample.

Adding unbinding works for me in onsleep()

protected override void OnSleep()
{
   NotificationCenter.Current.NotificationTapped -= LoadPageFromNotification;
}

Describe the bug
I have the NotificationCenter.Current.NotificationTapped += Current_NotificationTapped; in the App.xaml.cs file above the MainPage=new AppShell(); but no matter what I do this event is not triggered when I click on the notifications. As of writing this, I'm on the latest version of everything including ios, xamarin.forms and this plugin.

Describe the bug
On iOS, if ReturningData is null in NotificationRequest, then NotificationCenter.Current.Show results in an ArgumentNullException.
No issue on Android.

To Reproduce
Steps to reproduce the behavior:

1. Create a NotificationRequest without setting ReturningData (value should be null)
2. Call NotificationCenter.Current.Show for this notificationRequest
3. On iOS, the notification is not shown, and an exception is raised

Expected behavior
The notification should be shown on iOS (as it does on Android).

Platform:

• OS: iOS

Smartphone:

• Device: simulator (iPhone XR)
• OS: iOS 12.4

Additional context
Here is the exception:

[0:] System.ArgumentNullException: Value cannot be null.
Parameter name: str
  at Foundation.NSString..ctor (System.String str) [0x00009] in /Library/Frameworks/Xamarin.iOS.framework/Versions/12.16.0.5/src/Xamarin.iOS/Foundation/NSString.cs:159
  at Plugin.LocalNotification.Platform.iOS.NotificationServiceImpl.Show (Plugin.LocalNotification.NotificationRequest notificationRequest) [0x00036] in <a9531fbd8e004bca81f421001d65427d>:0

I suspect something is wrong in this part of the code (in NotificationServiceImpl for iOS, method Show):

using (var returningData = new NSString(notificationRequest.ReturningData))
{
           userInfoDictionary.SetValueForKey(
                  string.IsNullOrWhiteSpace(notificationRequest.ReturningData)
                       ? NSString.Empty
                       : returningData, NotificationCenter.ExtraReturnDataIos);
}

Maybe you should test for IsNullOrWhiteSpace before creating the NSString ?

Hi,

Is it possible with the current version (v4.0.6) to get the Local Notifications even when the app is not running?
I have a sample code which is working fine when the app is running (foreground and background) and the Android app displays the notification, but when I kill the app, the notification is not sent/received.

Thanks,
S.

Describe the bug

To Reproduce
Steps to reproduce the behavior:

1. Create a SplashActivity class.
2. Set its MainLauncher to true.
3. Start MainActivity inside its OnCreate method.
4. Create a notification
5. Tap on the notification

Expected behavior
NotificationTapped event gets fired

Hello,

I have this error on the project Xamarin.Froms.Android with version 4.0.3 :

Error: error: cannot access ListenableFuture public class ScheduledNotificationWorker class file for com.google.common.util.concurrent.ListenableFuture not found

Does this come from the plugin or an implementation error?

4.0.6 version not working in xamarin.ios 12.4. Checked with 4.0.5 also same issue. Android version is working fine. Issue with ios only.
"Notification is not raising"

I've put all the sample code in my application, and it worked perfectly fine on IOS and Android version 7.1 and below. But on Android 8.0 and above, it won't work. Maybe I missed something?

Here's the code i've inserted to my application.

var notifications = new NotificationRequest
{
NotificationId = 100,
BadgeNumber = 10,
Title = "sample title",
Description = "sample description",
ReturningData = "sample data",
NotifyTime = DateTime.Now.AddSeconds(1),
Android =
{
IconName = "download.jpg",
ChannelId = CrossDeviceInfo.Current.Version.ToString(),
Priority = NotificationPriority.Max,
AutoCancel = false,
TimeoutAfter = TimeSpan.FromSeconds(5),
Ongoing = true,
Color = 255,
LedColor = 255
}
};
NotificationCenter.Current.Show(notifications);

any sample please?

Describe the bug
After setting NotificationRequest.Android.IconName, the notification icon on Android is still the default icon.

To Reproduce
Steps to reproduce the behavior:

1. Add notification icon (e.g. icon.png) to Resources/drawable.
2. Initial NotificationRequest object and set Android.IconName to "icon".
3. Try to push notification.
4. Notification icon is the default one

Expected behavior
Notification icon should be the customised one.

Platform:

• Plugin Version: 4.1.1
• OS: Android 9 (Pie)
• Emulator: Pixel 2 XL

Additional context
Notification icon can be set only when setting NotificationRequest. Android.IconName to the resource id of the icon (which can be found inside Resource.designer.cs)

var notification = new Plugin.LocalNotification.LocalNotification
{
    NotificationId = 100,
    Title = "Test",
    Description = "Test Description",
    ReturningData = "Dummy data", // Returning data when tapped on notification.
    NotifyTime = DateTime.Now.AddSeconds(30) // Used for Scheduling local notification, if not specified notification will show immediately.
};
NotificationCenter.Current.Show(notification);

This doesn't complile, new NotificationRequest should be used instead

Hello is possibile to schedule notification for a future date?
Will this notification persist after phone reboot?
Thanks for your plugin!

I have this warning when building my app:
NU1107: Version conflict detected for ....

Could you please publish a Plugin.LocalNotification 4.0.7 referencing Xamarin.Android.Arch.Work.Runtime 1.0.0.3 instead of 1.0.0 ?

xamarin/AndroidSupportComponents/issues/204

1. Compile your sample project using Android 10
2. Run on emulator with android 9
3. Notification icon is fully white circle

I also tried icons from clipart (Android notification icons) and they also display incorrectly - always full square.

Is your feature request related to a problem? Please describe.
this Notification plugin is great, but its always using default notification sound. please add feature to custom notification sound each notification

Describe the solution you'd like
sound file may stored on res/raw (Android), so in pcl project just input the name of file in NotificationRequest

Describe alternatives you've considered

Additional context
thank you

Hi,

I am getting:

error: cannot access ListenableFuture public class ScheduledNotificationWorker class file for com.google.common.util.concurrent.ListenableFuture not found LocalNotifications.Android C:\Users\jrahm\Source\Repos\LocalNotifications\LocalNotifications\LocalNotifications.Android\obj\Debug\90\android\src\md50e8eea8286f69b03ef3779df0abd57a6\ScheduledNotificationWorker.java 4

I can use the NotificationTapped event to listen to notification interactions while the application is running, however, this event does not get fired when the App had to be started (was not running).

Consider the following scenario.

1. I schedule a notification to be displayed in an hour.
2. The user kills the application before the notification is displayed.
3. The user taps the delayed notification.

When the application starts, I would like to be able to receive data of the notification that caused the application to start so I can i.e display the correct page.

Is that possible?

Hi,

How can I make the Local Notification triggered in the background even when the app is closed?

Thanks,

I could not change notification icon in Xamarin.forms project.

There is option android in

                NotificationId = notification_id,
                Title = body,
                Description = body,
                ReturningData = "Dummy data", // Returning data when tapped on notification.
                                           
                NotifyTime = myDateTime

Hi,

How can I prevent LocalNotification from sending the message when device is switched on again?

For example, here is my scenario..

I am sending a reminder for prayer time so the app is storing the times and scheduling the messages, let's say the next prayer is at 13:00 and before that the user has switched off his device, and he switched it on at 13:30, in this case I don't want the message to be sent because the time for the prayer is 13:00 so he should not get the message for that prayer

Hi,

thank you for this great plugin and accepting the PR.

I'm still testing with the channel. When I change the description of the channel name, the settings are set back to default. The NotificationManager can retrieve the channel if it exists with GetNotificationChannel(string channelId).

I checked the android docs:

CharSequence name = getString(R.string.channel_name);
String description = getString(R.string.channel_description);
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);
channel.setDescription(description);
// Register the channel with the system; you can't change the importance
// or other notification behaviors after this
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);

Priority can't bet set for each NotificationRequest, it is only working for the first. I don't know what is better: Extend INotificationService with and AndroidCreateChannel Method and remove Priority and ChannelDescription from AndroidOptions, or creating the channel with the first NotificationRequest. With second option, the comment should be extended.

I'm wondering why the channel is recreate, when I change the channel description.

Describe the bug
I have a solution implementing scheduled local notifications. On Android notifications are sometimes delayed (0 - 40 seconds). What we need in our project to schedule local notification on specified time interval.

I created solution replicating this issue. This project schedules 2 notifications. The first one is scheduled after 60 seconds and second one 120.

To Reproduce
Steps to reproduce the behavior:

1. Download and run LocalNotificationTestingFinal
2. Click on the button bellow
3. Observe countdown and how notifications are sometimes delayed

Expected behavior
Notifications should be triggered exactly on specified second time interval.

Screenshots
NA

Smartphone (please complete the following information):

• Device: Sasmung S8
• OS: Android 9
• Version: API 28

Additional context
LocalNotificationTestingFinal.zip

I implemented a JobScheduler to show notifications.
The notifications are nicely shown after I opened my app and the jobscheduler gets triggered.
When I minimize my app the job keeps processing and the notifications are shown.

After reboot my job is still triggered and processing, but the notifications are not shown and the
I added logcats to see if the job is working properly and everything seems fine.
Do I miss any special setting to allow showing notifications after the reboot?

there is no such a property which can be use to repeat a local notifications using this plugin.
For Example: If i want to set a schedule for Monday and Tuesday 5 pm and want to get notification every Monday and Tuesday of each week on Same time till I cancel the local notification than there is no scope to do that using this plugin.
