I cannot use the librarte in a MAUI project, will you support MAUI in the near future?

MAUI is fully supported.

Can you provide us more details?

  • What package(s) are you trying to use?
  • What error(s) do you get?

MAUI is supported. You need to try in Platform specific folder (Platforms/Android/) because WebViewAssetLoader is Android only API.

I have a project developed in Xamarin.Forms and It uses the class WebViewAssetsLoader, but this class is not available for MAUI.

WebViewAssetLoader

https://developer.android.com/reference/androidx/webkit/WebViewAssetLoader

is bound in WebKit nuget:

https://www.nuget.org/packages/Xamarin.AndroidX.WebKit

generated/androidx.webkit.webkit/obj/Release/net6.0-android/generated/src/AndroidX.WebKit.WebViewAssetLoader.cs
generated/androidx.webkit.webkit/obj/Release/monoandroid12.0/generated/src/AndroidX.WebKit.WebViewAssetLoader.cs

Hi!

When I add the nuget package Xamarin.AndroidX.WebKit to my MAUI project, the code looks good as far as VS identifies the class properly and intelisense works. But when I build the project, it fails throwing this error:

This got me the fix, after pasting the code:

  1. Quit VS Studio.
  2. Reopen VS Studio
  3. Clean, then Build Project.
  4. Android Emulator/Device should be working.
