Custom badge with number for app icon is not showing for Android devices - working for iOS device

Question

Trying to show a custom badge on app icon based on some data in the app. I am using xamarin forms for both Android and iOS apps.
The logic and code is working fine for iOS but not for Android. Tried various suggestions, dependency services and plugin but on Android it is not working.
One thing to note is that the badge is showing in case of Push Notifications but if we want to show some custom badge at all times on App icon. that is not working.

Below is the source code for custom badge showing on iOS. Can someone guide me on how can I achieve the same result on Android.
public void SetBadge(int number)
{​​​​​​​
try
{​​​​​​​
var settings = UIUserNotificationSettings.GetSettingsForTypes(UIUserNotificationType.Badge, null);
UIApplication.SharedApplication.RegisterUserNotificationSettings(settings);
UIApplication.SharedApplication.ApplicationIconBadgeNumber = number;
}​​​​​​​
catch (Exception ex)
{​​​​​​​
Crashes.TrackError(ex);
}​​​​​​​
}​​​​​​​

Hello,​

Welcome to our Microsoft Q&A platform!

Unfortunately, Android does not allow changing of the application icon because it's sealed in the APK once the program is compiled. There is no way to programmatically change it to a 'drawable'.

You may achieve your goal by using a widget instead of an icon. Widgets are highly customizable and can do what you want. Please see this thread.

Here is similar thread about how to achieve the Custom badge with number for app icon in Xamarin. It contains several ways to achieve it, you can try it.
