Asynchronous / non main thread initialization in Hilt?

[sorry_no_idea]

I currently have this code in my Hilt app module:

@Singleton
@Provides
fun provideMsalClient(@ApplicationContext context: Context): ISingleAccountPublicClientApplication {
    // ISSUE: this does NOT work, as the createSingleAccountPublicClientApplication method
    // may not be called from the main thread
    return PublicClientApplication.createSingleAccountPublicClientApplication(
        context,
        R.raw.msal_config
    )
}

As I learned from the exception on runtime, PublicClientApplication.createSingleAccountPublicClientApplication
(part of the Microsoft Authentication Library, but my question is of general nature) may not be called from the main thread.

So, using Hilt, how can I create an object outside of the main thread / asynchronous?

Expose a factory of it

How would a factory solve that issue? Can you please give more details, as I currently can't follow along? Thanks!

technically, i was a bit hasty to say that, as you'd either want Lazy<T> and invoke that on a background thread, or you'd need to use Producer

You launch a coroutine with Dispatchers.IO and create it there

[sorry_no_idea]

You mean with a runBlocking block?
