Using the Android Paging Library
Explore how to use the Android Paging Library to load large datasets in manageable chunks within RecyclerViews. Understand the core components like PagingSource, Pager, and PagingDataAdapter, and see how they optimize network and system resource usage while supporting Kotlin coroutines and LiveData for reactive data streams.
Introduction
The Paging Library is part of the Jetpack library components. It makes it easier to load and display smaller chunks of data from a large dataset. It minimizes the development effort for optimally using network and system resources.
Paging Library features
The Android Paging Library provides quite a few default features and makes it easier to work with large datasets.
It provides in-memory caching of data for optimizing system and network resources.
It provides request deduplication to avoid redundant network calls.
It integrates with the
RecyclerViewand lets us load more data as the user scrolls.It works with
LiveData, Kotlin coroutines, and RxJava.
