PersistState

Annotate a field in your MvRxViewModel state with PersistState to have it automatically persisted when Android kills your process to free up memory. MvRx will automatically recreate your ViewModel when the process restarts with these fields saved.

You should ONLY SAVE what you need to refetch data, not fetched data itself. For example, for search, save the search filters not the search results.

You can also only annotate Serializable and android.os.Parcelable fields.

An example state class could look like: data class State(@PersistState val count: Int = 0)
