Android Jetpack: Manage infinite lists with RecyclerView and Paging
summary
Introduces the Paging Library that turns a LiveData list into a lazy-loading PagedList backed by Room or network (Retrofit), shows adapters like PagedListAdapter, and demonstrates a complete DB+network flow using a boundary callback that inserts network pages into Room. Examples include avoiding creating 10,000 objects for an 8–10 item view, configuring page size = 30, placeholders vs no placeholders, and three DataSource types (Positional, ItemKeyed, PageKeyed); Paging 1.0 is released and works with Rx.
