Implement Flow extension method to generate a PagingSourceFactory Extension method on Flow<List<Value>> to generate a pagingSourceFactory to be supplied to a Pager by calling flow.asPagingSourceFactory(). This factory extends InvalidatingPagingSourceFactory which internally tracks the PagingSources generated from this factory to faciliate PagingSource invalidation by external sources. In this implementation, the PagingSources are invalidated whenever a new List is collected from the Flow, with each emission representing a new generation. Test: ./gradlew paging:paging-testing:test Bug: 235528239 Relnote: Helper method to create a pagingSourceFactory from a FLow<List<Value>> to be supplied to a Pager. Each List<Value>> emitted from the Flow represents a generation of Paged data. This facilitates paging tests on, for example, PagingData transformations by faking a data source for the Pager to collect from. Change-Id: I6f230da9825c187eb0d8ae6645df7f0a67925574
Jetpack is a suite of libraries, tools, and guidance to help developers write high-quality apps easier. These components help you follow best practices, free you from writing boilerplate code, and simplify complex tasks, so you can focus on the code you care about.
Jetpack comprises the androidx.*
package libraries, unbundled from the platform APIs. This means that it offers backward compatibility and is updated more frequently than the Android platform, making sure you always have access to the latest and greatest versions of the Jetpack components.
Our official AARs and JARs binaries are distributed through Google Maven.
You can learn more about using it from Android Jetpack landing page.
For contributions via GitHub, see the GitHub Contribution Guide.
Note: The contributions workflow via GitHub is currently experimental - only contributions to the following projects are being accepted at this time:
When contributing to Jetpack, follow the code review etiquette.
We are not currently accepting new modules.
Head over to the onboarding docs to learn more about getting set up and the development workflow!
Our continuous integration system builds all in progress (and potentially unstable) libraries as new changes are merged. You can manually download these AARs and JARs for your experimentation.

AndroidX uses git to store all the binary Gradle dependencies. They are stored in prebuilts/androidx/internal
and prebuilts/androidx/external
directories in your checkout. All the dependencies in these directories are also available from google()
, jcenter()
, or mavenCentral()
. We store copies of these dependencies to have hermetic builds. You can pull in a new dependency using our importMaven tool.
