…ink to a lifecycle owner? The problem is with Hilt, there is a memory leak. The memory leak is because Epoxy link the view pool to the activity however, when a view get inflated in a Hilt fragment, the context is a wrapper and hold a reference on the fragment. The fragment leak. So why Epoxy link the view pool arbitrary to the `Activity`. Instead, could we use the view's context and find the closest `LifecycleOwner`. Use the `LifecycleOwner`'s lifecycle ti decide when to clear the pool. However this change won't be enough to fix the memory leak we have with Hilt. We will also need this change in Hilt :

I think this makes a lot of sense, and is cleaner anyway. I can't think of any cases it wouldn't work in, although I also don't know when the context wouldn't be an Activity (possible a Compose context? but epoxy wouldn't really be used there anyway, unless we have some interop)

This is a proposal and will require an update to Hilt, see google/dagger#2202 (comment).
The idea of theses changes in to Epoxy and Hilt are to fix a memory leak. It happen because Epoxy link the view pool to the activity. However, when a view get inflated in a Hilt fragment, the view's context is a wrapper and hold a reference on the fragment. The fragment leak for the whole activity lifecycle.
So why Epoxy link the view pool arbitrary to the
Activity? Instead, could we use the view's context and find the closestLifecycleOwner. When this lifecycle get destroyed we can clear the pool.It is a proposal, happy to discuss here. Using the
LifecycleOwnerinstead ofActivitylooks natural. Is it possible to use Epoxy outside of anActivitythat is not aLifecycleOwner?
