Caching buildSrc resolutions This reduces the time to run `./gradlew :help --console=plain` on my desktop from about 1.731 seconds to about 1.349 seconds This also reduces speeds up Android Studio by a comparable amount: When I run `./gradlew studio` on my desktop, and open ./room/runtime/src/test/java/androidx/room/BuilderTest.java, and click to run the nullContext test, Android Studio reports a certain amount of time spent by the Gradle build. Before this change, that time is about 1.3s After this change, that time is about 0.9s This only increases the time to run `./cleanBuild.sh -y :help` from 56s to 58.5s Bug: 144998998 Test: treehugger runs busytown/androidx.sh Test: Run `./gradlew --rerun-tasks :help --debug | grep "Gradle source classpath"` before and after this change and see that the classpath exported by buildSrc is unchanged except for the addition of these files, caused by adding hilt-android-gradle-plugin: prebuilts/androidx/external/com/google/dagger/hilt-android-gradle-plugin/DEV-SNAPSHOT/hilt-android-gradle-plugin-DEV-SNAPSHOT.jar prebuilts/androidx/external/org/javassist/javassist/3.26.0-GA/javassist-3.26.0-GA.jar Change-Id: Iba9a7833b50f8c38ac3cc68095b72a6a5492f42d
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.
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-master-dev cd androidx-master-dev
repo
command to initialize the repository.repo init -u https://android.googlesource.com/platform/manifest -b androidx-master-dev
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/ ./studiow
and accept the license agreement when prompted. Now you're ready edit, run, and test!
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/' }
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-4v-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.
