Android MVP WeakRefrence

Question

In mvp we save that reference of an activity in a weak reference. WeakReference<Activity> view = new WeakReference<Activity>(activity); If we lose the reference. can we get it back?

Answer 1

If you lose the reference to your Activity it means the activity was garbage collected and it doesn't exist anymore. You can't get back what doesn't exist.

Ex. If this happens because of configuration change it means a new activity was created.

You need a way to attach the newly created view to the same presenter.
