Connectivity.ConnectivityChanged handler does not work on Android 14

XamarinEssentialsBug-ConnectivityChanged

A repo to demonstrate a bug in Xamarin Essentials.

Description

Connectivity.ConnectivityChanged handler does not work when targeting API 34 on Android 14 phones.

With other combinations of API levels and Android version it seems to work.

This is the same bug already reported and fixed in Maui: Adding a Connectivity.ConnectivityChanged handler does not work on Android 14 #19949.

Project overview

This is a basic template Xamarin project. In App.xaml.cs i have added the following in the constructor:

Connectivity.ConnectivityChanged += Connectivity_ConnectivityChanged;

And the following method:

        private async void Connectivity_ConnectivityChanged(object sender, ConnectivityChangedEventArgs e)
        {
            Console.WriteLine("Connectivity changed");
        }

Stepts to reproduce

Download and compile this project targeting API 33 or run it in an Android 13 emulator. When you make change on the connectivity (switch flight mode on and off), the line 'connectivity changed' appears on the console.

When compiling for API 34 and running in an Android 14 emulator, nothing appears on console (Connectivity_ConnectivityChanged is never reached).
