How to use Shiny in an Avalonia iOS/Android project?

[teklot]

I want to use Shiny in an Avalonia iOS/Android project. My understanding is I have to first wire in the Shiny services using the UseShiny through the app builder, but the problem is UseShiny is not available for Avalonia iOS/Android app, so I have to utilize the Manual Hosting Model. Can someone please tell me how to register Shiny services manually or if there is an alternative method to wire in Shiny services? Thanks!

@teklot No idea. I don't use avalonia at all. I'm not sure what you mean by registering manually? The native hosting shows everything you need to wire up Shiny where MAUI isn't in use

@aritchie, by "registering manually" I mean registering the Shiny's services/modules manually which is done by UseShiny for MAUI. Right, the native and manual hosting show the boilerplate code but do not show how to register Shiny's services/modules.

For example, how do I "add shiny services" (part of the comment) in the code below to enable the resolution of IJobManager when using Shiny's Background Jobs? Thanks!

public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
    var host = HostBuilder.Create();

    // add shiny services & your own services here
    host.Build().Run();

    return base.FinishedLaunching(application, launchOptions);
}

UseShiny only covers the hooks within MAUI. HostBuilder does the equivalent of that stuff in the native module.

Once you have the host, you have access to the same basic service collection that MAUI uses, so:

var host = HostBuilder.Create();

host.Services.AddJob(...);
host.Build().Run();

return base.FinishedLaunching(application, launchOptions);

Great! It's working like a charm. I did not pay enough attention to the host.Build().Run(), it is indeed does the job. Thanks!

Hi Aritchie hi teklot,
 
 
@aritchie will this be supported in the future? like UNO Hosting. Avalonia also offers the possibility to use Microsoft.Extensions.DependencyInjection.
https://docs.avaloniaui.net/docs/guides/implementation-guides/how-to-implement-dependency-injection
 
@teklot
could you provide me with a sample project of how you linked this to the shared folder?
 
Many thanks to both of you

@HausBJB It is supported through the native integration. If you mean something as simple as "UseShiny", well... that's a platform thing. The MAUI team setup a great set of hooks to start. Uno & as far as I know, Avalonia - do not have the platform hooks that would allow me to do that. Uno doesn't have hosting in Shiny.

Ok, that's a shame of course. With UNO, I thought that was it.

But I must have misunderstood

Thank you very much!
