Cluster Manager Save Instance State
Is your feature request related to a problem? Please describe.
Throughout a Fragment's lifecycle, Android can be quite aggressive when destroying and recreating a fragment's view. It's almost certain to require instance state restoration when a user navigates from a fragment that hosts a MapView
.
In my case, I'm forced to recreate a ClusterManager
to redraw my markers when the host fragment is made visible again. Recreating custom markers can be a time consuming process, and a visual blip in the map can negatively affect the user experience.
Describe the solution you'd like
A first-class feature that allows the ClusterManger
to be rebound to a newly created map view, allowing for fast recovery of the MapView's state including all markers and state of interaction e.g. restoration of a visible item info window that was activated before the view was destroyed.
Describe alternatives you've considered
I haven't seen any documentation on how to handle UI state restoration. I'm wondering if I need to:
- Cache custom marker Bitmaps in memory
- Keep track of active item info windows
Additional context
Thanks in advance. I can provide additional context as needed to clarify my concern.
