Migrating to Paging Library
summary
Step‑by‑step migration from RecyclerView.Adapter to Android Paging Library with Room and LiveData, replacing LiveData<List> with LiveData<PageList> and switching ListAdapter to PageListAdapter; example config uses page size = 30 and default initial load = 3×page size. Covers DataSource types (positional, item‑keyed, page‑keyed), how placeholders return null and require null handling, and using BoundaryCallback to fetch from network into Room when database is out of data. Results: lower memory use, background diffing, clearer UI/data separation and easier unit testing.
