Using the Android Paging Library

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 RecyclerView and lets us load more data as the user scrolls.

• It works with LiveData, Kotlin coroutines, and RxJava.
