Type inference failed: fun <T : Any!> getSystemService(context: Context, serviceClass: Class<T!>): T?
cannot be applied to
(String)

Type mismatch: inferred type is String but Context was expected

I just used the code provided here https://developer.android.com/guide/topics/text/copy-paste

var clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
var pasteData: String = ""

And i get this error

You’re using getSystemService from core-ktx library and it’s a function with reified generic parameter. So you need to instead wrote getSystemService<ClipboardManager>()

@wasyl still not working, this is in my ViewModel, it's troubleing me for a while now. Everyone does it this way but it doesnt work for me

[wasyl]

Oh, in that case you can’t get system service from a class that doesn’t extend a Context

[wasyl]

and ViewModel doesn’t

Yeah I've done some research now, but I am still confused. I want to keep my logic away from my fragment and in my viewmodel. So i just call

override fun quoteClicked(quote: Quote) {
        viewModel.copyText(quote)
    }

in my fragment, but now I need a way to copy text in the viewmodel. Any pointers/ help/ article would be appreciated. Not sure what to do
Thanks by the way @wasyl

If you are using dependency inversion (Dagger, Koin, etc.), you could inject the ClipboardManager so you can supply a mock version in testing. Otherwise, you could have your viewmodel extend AndroidViewModel and use the application to call getSystemService().

Hmm I'll do the DI approach, thanks!
