We have an AndroidView which reads from a lambda passed into the function, which is stable

AndroidView(factory = { context -> 
    onViewCreated()
    ...
  }
)

However this is causing the factory function to be called, and the underlying view to be re-created on every configuration change. The lambda is ultimately created this way:

val onViewEvent = remember(viewModel) { viewModel::onViewEvent }
val onViewCreated = { onViewEvent(SomeViewEvent) }

The problem I'm seeing is that remember doesn't survive configuration changes, so onViewEvent gets remember'd again with a new reference (even though the viewModel instance is the same) and we can't use rememberSaveable with lambdas (and I'm not sure it feels right to do so!)

Has anyone dealt with this before and figured out a solution?

Do remember {} get preserved during configuration changes? I thought the entire compositions gets recreated since the Activity is getting recreated? Have you disabled that functionality first?

Can you put a println statement in your Activities onCreate(Bundle) and see if it get printed every time you rotate your device?

@luke_c the factory function is called on every configuration change because of the configuration change (re-creating Activity & composition), not because of onViewEvent changing. Is that what your question is about?
