I am trying to view a list of item. From mainActivity class, I am passing arrayList of item to composable function. But while running the app, I am getting this error java.lang.RuntimeException: Unable to start activity ComponentInfo{<http://package.name/package.name.MainActivity|package.name/package.name.MainActivity>}: java.lang.IllegalStateException: Composition requires an active composition context

My mainActivity class

class MainActivity : AppCompatActivity() {
    var dashboardList: ArrayList<Dashboard> = ArrayList()
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        fillDummyData()
        setContent {
           MainScreen(dashboardList)
        }
    }
    fun fillDummyData() {
        dashboardList.add(
            Dashboard(title="Sample title",preview="nfjsad dsaf  safsadf ", image= +imageResource(R.drawable.icon), dateTime = "Aug 10", isOnline = "true")
        )
    }
}

If i remove fillDummyData function everything is working fine.

You’re calling Dashboard which I guess is a @composable function outside a composition

[Luca Nicoletti]

Try adding a model to the list, and reference the model from a @Composable function

[amar_1995]

Dashboard is a data class

[amar_1995]

Okay
I got your point +imageResource is composable function
Now making fillDummyData function @Composable is working

[Luca Nicoletti]

Hmmmm

[Luca Nicoletti]

Not sure that’s the best solution though

[Luca Nicoletti]

I’d store the ID in the dataclass

[Luca Nicoletti]

and retrieve the actual image inside a composition

[Luca Nicoletti]

so from a function which is somewhere `inside`/`nested` in the setContent - which is to be considered a starting point for composition

[Luca Nicoletti]

as it interally calls Compose.composeInto()

[amar_1995]

Okay i will do the same
Thanks.
