Why do you need this? ComponentActivity is way to go for all cases

There is a use case which requires FragmentActivity or Fragment for initialisation. But in Compose it's giving error if I am directly passing Activity so needs this conversions. Is it possible ??

ComponentActivity is Activity, no need to cast

Copy code
private fun getContextFromComponent(): Context? {
        return when (val componentCallbacks = componentCallbacksWeakReference.get()) {
            is Fragment -> {
                componentCallbacks.context
            }
            is FragmentActivity -> componentCallbacks
            else -> null
        }
    }

If some API requires FragmentActivity, you just should extend it, it cannot be "casted" somehow
What are you trying to do in this code? What is componentCallvacks?

Yes. Agree. But passing Activity as a parameter to my use case which needs Fragment or FragmentActivity as a instance gives me error as this cast can't be succeed
This is the Use case

Right, just extend FragmentActivity, not ComponentActivity
