Updates Material components to have a minimum touch target size Button, Slider, Checkbox, RadioButton, and Switch have a visual size smaller than the minimum touch target size of 48x48dp. This means that even with the recent touch target expansion work, in many cases there will not be enough space for hit testing to expand, meaning that these components are not accessible. This CL adds extra space around these components if they are smaller than 48x48, to make sure that there will be enough size for the expanded hit testing to work, ensuring that these components have an accessible touch target. Also updates Snackbar and AlertDialog to account for the new larger size of buttons in their layout implementation. Bug: b/149691127 Fixes: b/171509422 Fixes: b/150377503 Fixes: b/174707736 Test: existing tests, new tests Relnote: "Adds minimum touch target sizing for Material components that do not have an accessible touch target. As this adds extra spacing around components to make sure they have a large enough touch target, this may change existing UIs that assume the size of these components is their visual size, and doesn't account for touch target size. You can use the experimental LocalMinimumTouchTargetEnforcement composition local to disable this behavior across a hierarchy, but this is intended only to be a temporary escape hatch while updating existing UIs to account for the new minimum size."

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.
NOTE: You will need to use Linux or Mac OS. Building under Windows is not currently supported.
repo
(Repo is a tool that makes it easier to work with Git in the context of Android. For more information about Repo, see the Repo Command Reference)mkdir ~/bin PATH=~/bin:$PATH curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo chmod a+x ~/bin/repo
git config --global user.name "Your Name" git config --global user.email "you@example.com"
mkdir androidx-main cd androidx-main
repo
command to initialize the repository.repo init -u https://android.googlesource.com/platform/manifest -b androidx-main --partial-clone --clone-filter=blob:limit=10M
repo sync -j8 -c
You will use this command to sync your checkout in the future - it’s similar to git fetch
To open the project with the specific version of Android Studio recommended for developing:
cd path/to/checkout/frameworks/support/ ANDROIDX_PROJECTS=MAIN ./gradlew studio
and accept the license agreement when prompted. Now you're ready to edit, run, and test!
You can also the following sets of projects: ALL
, MAIN
, COMPOSE
, or FLAN
If you get “Unregistered VCS root detected” click “Add root” to enable git integration for Android Studio.
If you see any warnings (red underlines) run Build > Clean Project
.
You can do most of your work from Android Studio, however you can also build the full AndroidX library from command line:
cd path/to/checkout/frameworks/support/ ./gradlew createArchive
You can build maven artifacts locally, and test them directly in your app:
./gradlew createArchive
And put the following at the top of your ‘repositories’ property in your project build.gradle
file:
maven { url '/path/to/checkout/out/androidx/build/support_repo/' }
NOTE: In order to see your changes in the project, you might need to clean your build (Build > Clean Project
in Android Studio or run ./gradlew clean
).
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.
Run FooBarTest
Run androidx.foobar
The AndroidX repository has a set of Android applications that exercise AndroidX code. These applications can be useful when you want to debug a real running application, or reproduce a problem interactively, before writing test code.
These applications are named either <libraryname>-integration-tests-testapp
, or support-\*-demos
(e.g. support-v4-demos
or support-leanback-demos
). You can run them by clicking Run > Run ...
and choosing the desired application.

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.
