Make colors in MaterialTheme of M2.5 immutable Based on the recommendation from the API council, making the Colors of M2.5 immutable which improves the performance. Related CL for Wear Compose M3: https://android-review.googlesource.com/c/platform/frameworks/support/+/2871294 Results from the benchmarks added * Before the change: 2.39 ms and 1013 allocs * With the change: 2.145 ms and 906 allocs We improve the initialisation by around 0.2 ms and 107 allocations. Bug: 318814129 Test: Existing tests and new benchmarks Relnote: """ Colors is now Immutable, making individual color updates less efficient, but making more common usage of colors more efficient. The reasoning behind this change is that the majority of apps wouldn't have updating individual colors as a main use case. This is still possible but it will recompose more than before, in turn we significantly decrease the amount of state subscriptions through all of material code and will impact initialization and runtime cost of more standard use cases.

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.
