SvgImageSource.FromFile etc

@daniel-luberda Thanks! I'm new to Xamarin... is that something I do in Xaml or code?

[kieronlanning]

Updated to bind to a view model now, but the icon doesn't appear.

I've also included the same icon on the page (as content) using the same code, and it's fine.

Tried a variety of things to make sure it's picking up the correct file and content, and it's fine on page, but not in the Tab Icon.

@candidodmv It's on the Xamarin backlog: https://github.com/xamarin/Xamarin.Forms/issues/6477

I did some research:

Android is using IImageViewHandler and IImageSourceHandler - FFImageLoading implements both, but FFImageLoadingImageSourceHandler is ignored and cannot be registered. Shell tabs are relying on IImageSourceHandler, that's why no icons are displayed.

This issue could be resolved by simply adding an InitImageSourceHandler routine for Android, similar to iOS.

@daniel-luberda I would go for a PR if that makes sense for you.

Any updates?

using FFImageLoading.Forms.Platform;
using FFImageLoading.Svg.Forms;

// FFImageLoading.Forms.Platform
namespace Application.Droid
{
    public static class SvgImageRegister
    {
        public static void Init()
        {
            Xamarin.Forms.Internals.Registrar.Registered.Register(typeof(SvgImageSource), typeof(FFImageLoadingImageSourceHandler));
        }
    }
}

@candidodmv It's on the Xamarin backlog: xamarin/Xamarin.Forms#6477

Xamarin says it is an issue on FF side:

This is not a Xamarin Forms issue, FFImageLoading does not register IImageSourceHandler for Android (see comment).

you can use a tabbed page like this:

This is not using Xamarin Shell

See my post on May 22nd, same as @Dresel already pointed out. Call SvgImageRegister.Init()
