Significantly improve the performance of SupportMenuInflater By preventing the dispatch of change events until all items are inflated, we only send one change event rather than n. This can potentially be multiple frames's worth of time with realistic numbers of menu items. Fixes: 253460617 Test: Manual, used the sample app at https://github.com/borysboykogoogle/ToolbarMenuInflationLatencyExploration with an additional 500ms delay to the Fragment's menu inflation. Confirmed that without the changes, menu inflation is much slower in the Fragment version, and with the changes, they're about equal. Also added new tests to MenuBuilderTest Change-Id: I0b0875546d4817576a9d360a890eccce60555884
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.
