SelectionTracker.Builder isn't working IllegalArgumentException

Question

I am trying to implement recyclerView multi-selection but I get java.lang.IllegalArgumentException on StorageStrategy.createLongStorage()

here is my code

tracker = new SelectionTracker.Builder<>("selection1"
                , recyclerView
                , new StableIdKeyProvider(recyclerView)
                , new MyItemDetailsLookup(recyclerView)
                , StorageStrategy.createLongStorage())
                .withSelectionPredicate(SelectionPredicates.<Long>createSelectAnything())
                .build();

Answer 1

You need to call recyclerView.setAdapter(...) before SelectionTracker.Builder<>(...).build()

Answer 2

This is probably because at this point the adapter of the RecyclerView has not been set.
