Fix back stack changes during host lifecycle changes When we dispatch lifecycle changes to destinations because of back stack changes, we operate on a copy of the back stack to avoid reentrant changes - lifecycle observers that call navigate / popBackStack. Now, we do the same for host lifecycle changes, ensuring that any lifecycle observers that are triggered when the host lifecycle changes state also avoid any reentrant issues due to changing the back stack during the dispatch of the lifecycle change. Relnote: "Fixed a `ConcurrentModificationException` that could occur when a `LifecycleObserver` attached to a `NavBackStackEntry` triggers a change to the back stack when the host `LifecycleOwner` such as the containing Activity or Fragment changes its lifecycle state." Test: new NavControllerTest BUG: 377537292 Change-Id: Ia9494e9967aa45a7613c49d7530f524f5400d1ca
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()
, or mavenCentral()
. We store copies of these dependencies to have hermetic builds. You can pull in a new dependency using our importMaven tool.
