In Hilt is there a way to have a dependency scoped to @ActivityRetainedScoped but have a value injected to it from the Activity. I need the depedency to survive device rotation but the problem is it also needs a value taken from the `Activity`'s bundle. Any advise on how to work around this?

How about injection via setter?

Do you mean,

@Inject
lateinit var myObject: MyObject

...

myObject.setValue(someValueFromBundle)

??

yep

Or use a ViewModel and savedStateHandle

[allan.conda]

class MyViewModel @ViewModelInject constructor(
  @Assisted savedStateHandle: SavedStateHandle // your bundle args is here
): {
  private val myArg = savedStateHandle.get("arg_key")
}

the problem is that the inject value from the activity bundle should only work as the initial value... overtime that value would change.. now if the activity gets recreated because of device rotation... it value would be reset to the initial value from the bundle

for viewmodel inject, it works as you want it.
For setter injection, it’s just a matter of checking for savedInstanceState == null

I guess I will need to restructure the project to make this work. use ViewModel to hold the states instead of just a scoped object. making ViewModel hold states is probably the correct way anyway.

ActivityRetainedComponent is meant specifically for ViewModel
