NetworkInterface.GetAllNetworkInterfaces() on Android leads to FileNotFoundException #77441

Description

@kdotdk

Description

This has been reported previously in #3617 but problem still exists.

I have tried the following combinations:

  • Works on Android 9 API 28 (Physical Tablet)
  • Works on Android 10 API 29 (Visual Studio Pixel 5 Emulator, Win 10)
  • Fails on Android 11 API 30 (Visual Studio Pixel 5 Emulator, Win 10)
  • Fails on Android 12 API 31 (Visual Studio Pixel 5 Emulator, Win 10)
  • Fails on Android 13 API 32 (Visual Studio Pixel 5 Emulator, Win 10)
  • Fails on Windows 11 Windows Subsystem for Android Version 2207.40000.8.0

Steps to Reproduce

  1. Get MAUI sample app

  2. Add Permissions:
    [assembly: UsesPermission(Android.Manifest.Permission.AccessNetworkState)]
    [assembly: UsesPermission(Android.Manifest.Permission.ChangeNetworkState)]
    [assembly: UsesPermission(Android.Manifest.Permission.AccessWifiState)]
    [assembly: UsesPermission(Android.Manifest.Permission.ChangeWifiMulticastState)]
    [assembly: UsesPermission(Android.Manifest.Permission.ChangeWifiState)]
    [assembly: UsesPermission(Android.Manifest.Permission.Internet)]

  3. Add a call to System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces() on a button click (E.g. in AboutPage TabCommand)

Result the application crash with FileNotFoundException.

              Description

              This has been reported previously in #3617 but problem still exists.

              I have tried the following combinations:

              • Works on Android 9 API 28 (Physical Tablet)
              • Works on Android 10 API 29 (Visual Studio Pixel 5 Emulator, Win 10)
              • Fails on Android 11 API 30 (Visual Studio Pixel 5 Emulator, Win 10)
              • Fails on Android 12 API 31 (Visual Studio Pixel 5 Emulator, Win 10)
              • Fails on Android 13 API 32 (Visual Studio Pixel 5 Emulator, Win 10)
              • Fails on Windows 11 Windows Subsystem for Android Version 2207.40000.8.0

              Steps to Reproduce

              1. Get MAUI sample app

              2. Add Permissions:
                [assembly: UsesPermission(Android.Manifest.Permission.AccessNetworkState)]
                [assembly: UsesPermission(Android.Manifest.Permission.ChangeNetworkState)]
                [assembly: UsesPermission(Android.Manifest.Permission.AccessWifiState)]
                [assembly: UsesPermission(Android.Manifest.Permission.ChangeWifiMulticastState)]
                [assembly: UsesPermission(Android.Manifest.Permission.ChangeWifiState)]
                [assembly: UsesPermission(Android.Manifest.Permission.Internet)]

              3. Add a call to System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces() on a button click (E.g. in AboutPage TabCommand)

              Result the application crash with FileNotFoundException.
